Why I Wear a Flight Suit to Dry Cherries

Just a precaution.

In a comment to yesterday’s post about my work drying cherries, Miraz asked:

Could you write a post about your Nomex flight suit. What is it? What’s special about it? Why don’t you just wear whatever you normally wear when flying?

A good topic for a post, so here it is.

First, Nomex. Wikipedia describes Nomex as follows:

Nomex (styled NOMEX) is a registered trademark for flame resistant meta-aramid material developed in the early 1960s by DuPont and first marketed in 1967.

It can be considered an aromatic nylon, the meta variant of the para-aramid Kevlar. It is sold in both fiber and sheet forms and is used as a fabric wherever resistance from heat and flame is required […] Both the firefighting and vehicle racing industries use Nomex to create clothing and equipment that can withstand intense heat. All aramids are heat and flame resistant but Kevlar, having a para orientation, can be molecularly aligned and gives high strength….

The Wikipedia piece goes on to list the different uses of Nomex fabric, including this statement:

Military pilots and aircrew wear flight suits made of over 92 percent Nomex to protect them from the possibility of cockpit fires and other mishaps.

A Pickle Suit

Here’s an example of a flight suit available on Flightsuits.com. (And no, it doesn’t come with the guy.)

It’s not just military pilots. Nomex is also widely used in flight suits worn by EMS pilots and crew members and law enforcement pilots.

A flight suit is usually a one-piece, zip up garment, often with many pockets, that is worn by pilots and aircraft crew members. While they come in many colors and styles, they’re usually a military green or khaki color. The green suits (see photo) are sometimes referred to by the folks who wear them as “pickle suits.”

Flight suits can be made of any fabric, but since they’re available in Nomex, it seems silly to wear one that doesn’t offer the additional protection of the Nomex fabric. And although they come in long sleeve and short sleeve styles, it also seems silly to have Nomex protection on only half of your arms when you can get full arm coverage.

At least that’s the way I see it.

Why does a pilot need protection at all? Well, it’s mostly to save your life (or even just your skin) in the event of a post-crash fire. And fires are definitely possible when you’re carrying fuel (which you should be) if you hit the ground hard in a crash.

Safety Notice 40Robinson Helicopter Company recommends that all pilots — and even passengers! — wear flight suits. Safety Notice 40 was released in July 2006, possibly in response to an accident with a post-crash fire in Texas. Robinson often releases Safety Notices in response to what it sees as dangerous or potentially dangerous situations. Safety Notices are not requirements; they’re suggestions. They’re also Robinson’s way of “covering its butt.” The company is owned by Frank Robinson and is self-insured. By recommending that we wear flight suits, Robinson Helicopter cannot be held accountable for burn injuries if we’re not following their recommendation.

That’s not to say it isn’t good advice. It is. But it isn’t exactly practical to require every person on board a flight to wear a flight suit. And while I might be tempted to wear a flight suit more often if I actually looked good in one, I don’t. Besides, I’ve decided on a more professional “corporate pilot” appearance for my charter flights: slacks with a polo shirt or pilot shirt.

It’s a matter of risk assessment. Tour and charter flying has much lower risk associated with it. I’m usually operating at airports, landing and departing from locations very suitable for that kind of activity. Flight profiles remain outside the “deadman’s curve.” There isn’t anything unusually risky about these flights. Even most of my photo and survey flights are relatively low-risk.

But hovering 5-10 feet over cherry trees at 5-10 knots ground speed puts me firmly into the deadman’s curve. If I have an engine failure, there’s nothing I can do to prevent a messy crash into the trees. With lots of fuel on board, a post-crash fire is possible. Wearing a Nomex flight suit seems like a pretty good idea.

Helicopter Helmet

A helicopter helmet like the one I wear. This is a low-cost model available from AviationHelmets.com.

So does wearing a helmet. I can’t tell you how many articles I’ve read in helicopter flying magazines about the importance of wearing a helmet on high-risk missions. The main thing that worries me is the flinging parts that might just enter the cockpit in the event of a crash. It would be awful to have a soft landing only to have a main rotor blade enter the cockpit and split your head open like a coconut. (Ick. What a terrible visual.) Or even to just clock your head on the door frame hard enough to cause serious damage. The helmet protects me against this.

But I don’t think my passengers would feel very comfortable if I wore it on a charter flight.

So, in answer to Miraz’s question, I wear a flight suit for cherry drying because of the increased risks associated with that kind of flying. I don’t wear it for other, less risky missions because I’m trying to maintain a “corporate pilot” professional look for my passengers. And I look like a big khaki sausage in my flight suit.

Fortunately, the cherry trees — and growers — don’t care what I look like.

Quincy Clouds Time-lapse Movies

I draft my old G5 for time-lapse duty.

About two weeks ago, I got the bright idea that it was a complete waste of valuable camera resources to use my Nikon D80 for time-lapse photography when I had an older camera I could use. The other camera is my Canon PowerShot G5, which I bought back in 2003 for aerial photography work.

Buying the camera was a huge deal back then. Digital SLRs, if available back then, were too expensive to be an option. The G5 offered 5.0 megapixel (!) resolution — more than twice the resolution of any other digital camera we had. But it also included features we needed, including manual setting for focus and exposure.

Canon PowerShot G5Looking at the camera today, it’s amazingly big and clunky. But it takes a decent picture — certainly good enough for my time-lapse experiments. And frankly, I was having trouble getting my mind around leaving my Nikon outdoors, unattended, for hours at a time. It could be because the tripod got knocked over once and it was sheer luck that it fell toward a rail that caught it rather than toward the empty concrete behind it. I had no love for the G5; if it broke, well, that’s the way it goes. Ditto if it got stolen. In fact, I’d be more upset about losing my tripod or Pclix than the G5.

Oddly enough, the G5 has a built-in intervalometer — a fact I was unaware of. Unfortunately, the interval must be set in minutes (1 to 60) and it can only take 100 shots at a time. This simply wasn’t going to cut it for my needs. Besides, for some reason I still can’t understand, I can’t get the damn thing to work.

So I bought an optical cable for my Pclix. It arrived right before I left for Washington. I tried it for the first time on Friday.

For the optical cable to work, its end must be taped to the camera. The Pclix maker recommends electrical tape, so that’s what I used. Unfortunately, the heat of the day softened the tape. After about 2-1/2 hours, it shifted out of position. The camera stopped taking pictures. Here’s the result, with most of the beginning edited out (since there was really nothing going on):

Disappointing in so many ways. The sky was just getting interesting when the setup failed. And let’s face it — the view of the golf cart shed isn’t all that enticing.

So I tried again yesterday after recharging the camera’s battery overnight. I fixed up the camera differently and pointed it north instead of west. Same settings: one shot every minute, compiled into a movie at 10 frames per second. To prevent the camera battery from running out, I turned off the camera’s video screen. First shot at 9:13 AM; last shot at 7:33 PM. I left the camera outside all day long — even while I was out doing a helicopter ride. I never would have done that with my Nikon.

The result isn’t bad at all. I’m a little POed at myself for including the wires in the shot and it’s a little weird that some of the larger vehicles that drove by appeared in some shots — like the hay truck near the beginning! Again, I think I could have done better. But the clouds are so awesome in this movie. They build and move and swirl around. So cool. See for yourself:

I’ll keep working on this. Hopefully, I’ll get it right soon.

The Life of a Cherry Drying Pilot

What it’s really like.

Help Wanted!

I wrote this blog post way back in 2009. Since then, I’ve built a medium sized cherry drying business and have moved to the Wenatchee area to be close to my work. Each summer, I contract with five or more pilots to fly with me and help me cover my contracts. If you have an R44 helicopter and want a “paid vacation” in central Washington State next summer, I want to hear from you. Read this and then get in touch.

I’ve been writing a lot about my summer gig as a cherry drying pilot. Most folks focus on the flying or the money or the simple fact that I can perform what looks like an easy task, make money, and build flight time. Few people seem interested in what it’s really like.

The truth is, it’s neither fun nor glamorous. In fact, when you look at the big picture and understand the responsibility and potential danger involved, it’s rather tedious.

So I thought I’d take the time to fully describe what being a cherry drying pilot is all about.

An Introduction to Cherry Drying

Let me begin by describing what this is all about.

Cherries grow on trees in orchard blocks in the U.S. northwest (and elsewhere). Like other fruit trees, cherry trees flower in the spring and are pollinated by birds and bees and possibly by other methods I’m not familiar with. The fruits begin to grow.

Split CherryAbout three weeks before the cherries are ready to be picked, they are particularly vulnerable to threats that can damage them. One of those threats is water. When it rains, the water sticks to the cherries and can cause them to rot, split, or both. This makes the cherries far less valuable to buyers.

Cherry growers have long tried to find ways to dry the cherries and prevent the rot/split problems. They put fans on tall poles in their orchards and run blowers up and down the rows. But this isn’t usually effective. Enough rain in those last few weeks can destroy the entire crop.

Sometime in the past — maybe 10 or 15 years ago? — someone had the idea of using the downwash of helicopters hovering over the cherry trees to blow the branches around and shake the water off the cherries. This was extremely effective and apparently well worth the cost.

“Cherry drying” by helicopter was born.

How I Got Here

Learn more about helicopter cherry drying

I first heard about cherry drying a little over four years ago. I was looking for summer work with my helicopter and another helicopter pilot, who was based in Seattle, got in touch with me. He was trying to build a cherry-drying operation and wanted to get together a bunch of pilots he could call on each year.

Two years in a row, I almost got work doing this. But there wasn’t enough guaranteed work for me to make the 10-hour (each way) ferry flight from Arizona. Last year, there was. I flew up, stopped in Portland, OR to get some training with another pilot, and set up base in Quincy, WA. I was working for my pilot friend as a subcontractor for several growers and for another cherry drying provider.

Last year wasn’t very good for pilots — but it was great for growers. Why? It didn’t rain. I was on a variety of contracts for a total of seven weeks and only flew 5.2 hours. And because my assigned orchard blocks were so small, most of that time was spent flying from one to another.

This year, everything was a mess. My friend had let his business go because of a serious health problem so he wasn’t digging up work for me. The other cherry drying provider had promised me some work but, at the last possible minute, went out of business. Pilots like me were frantic, trying to find contracts for work. Growers were frantic, trying to find pilots. And out of this mess, with the help of some contacts I had from last year, I managed to get four contracts stretching out over a period of six weeks.

How It Works

The cherry drying work I do is on contract. This year, I contracted directly with growers (or orchard managers) for a 2 or 3 week period. During the contract period, the grower pays me a daily standby fee. Payment of this fee ensures that I will be available to come dry the orchard block within a reasonable period of time — usually within 20 minutes of the call to come.

When it rains, the grower calls. He usually calls at least twice:

  • The first call is what I call the “heads up” call. At this point, it’s either raining or very likely to rain on the orchard. The grower wants to make sure I’m aware that I’ll probably be called out to dry soon.
  • The second call is the call to action. The grower expects me to arrive as quickly as possible and get right to work.

When I’m finished drying and return to my base, I note the time flown as indicated on my Hobbs meter. At the end of the week, I bill the grower for the flight time at a pre-agreed hourly rate.

The Expenses

Because I can never depend on it to rain, I have to set my standby rate high enough to cover all of my fixed expenses. These expenses include:

  • Cost of transporting the helicopter between Arizona (where I live) and Washington (where I dry cherries).
  • Cost of getting my truck up to Washington and back.
  • Lodging expenses for the entire time; I save money by living in my small RV, which I tow up with my truck.
  • Meals and other living expenses.
  • Insurance. Last year I had to supplement my regular insurance with a second policy; this year I got a policy that covers all of my operations.

There are also a bunch of startup costs that have to be considered:

  • Helicopter. Medium sized helicopters with two-bladed systems are best. Think Robinson R44, Bell JetRanger, and Hiller. R22s and Schweitzer 300s generally don’t push enough air, although they can get into tighter spots.
  • Truck. It’s needed to provide ground transportation and haul around fuel.
  • 100-gallon fuel tank, pump, filter, and grounding strap so I can carry and pump aircraft fuel.
  • Helicopter helmet.
  • Nomex flight Suit.

As you can imagine, this can be a major investment. My fuel setup alone cost $2K. And have you priced up helicopter helmets lately?

Finally, the expense many people don’t consider: taking a normally revenue-generating helicopter offline.

You see, when you contract for cherry drying, you have to keep your helicopter near the orchards. That means you can’t hold it out for hire on other jobs. While my helicopter is here in Washington, I can’t be doing charter work down in Arizona. I have no customer base here. And even if I did, I couldn’t fly customers unless I was absolutely certain it wasn’t going to rain.

So suppose I’d fly 5 hours a week in Phoenix but can’t fly those 5 hours in Washington. That’s 5 hours of revenue lost each week. My standby rate has to compensate me for this potential loss of revenue.

What It’s Like

Cherry drying is a waiting game, one that turns you into a local weather expert.

Radar

Here’s the kind of analysis I make all day long when there’s weather moving in. The arrow indicates the direction of the weather movement.

Each day starts with a look out the window and at the current day’s weather. I have an Internet connection here, so I can check the weather from a variety of sources throughout the day. I also have a scanner with weather frequencies that broadcast official local weather 24 hours a day. If there’s no rain in the forecast and no clouds in the sky — like most days last season — you’re free to do what you like, as long as you keep monitoring the weather and can be back at base at the slightest hint of rain. But if there’s any rain in the forecast or any clouds in the sky, you need to stick around base, just in case those clouds turn rain-bearing and they drop moisture on your assigned orchard blocks.

Or maybe the day starts with a phone call. Like today.

The point is, when you’re on contract and being paid standby money, you’re responsible for making sure you’re available quickly when called. That means you can’t screw around and do whatever you want wherever you want. If it looks like rain, you need to be ready to fly. Even if it doesn’t rain and you don’t get the call.

For me, that means spending a lot of time hanging around my RV at the golf course. (It’s almost unfortunate that I don’t golf.) It means having access to weather information and having something to do to keep busy so you don’t die of boredom. It means keeping your cell phone fully charged and in a place where it gets a good signal.

It doesn’t mean disappearing to Seattle for a few days without telling anyone. That’s a horror story I heard from a guy who hires pilots as subcontractors. He’d hired one irresponsible pilot who didn’t take the job seriously. When he called the guy to fly, the guy admitted that he was in Seattle and couldn’t get back for hours. That’s too late. The crop would be destroyed by then.

For the amount of money we’re being paid to hang around, the least we could do is hang around.

Oh, and did I mention how long the days are here up in North Central Washington in June and July? Sunrise is at around 5 AM. Sunset is around 9 PM. I have to be available for all daylight hours. That means I have a 17-hour work day.

The Work

Of course, sooner or later those calls will come.

On the first call, I prepare the helicopter and myself for flight. For the helicopter, that means taking off the cockpit cover (if it’s on). I’ll also remove the blade tie-downs, but only if a storm isn’t approaching my position. The helicopter is already pre-flighted. Then I’ll go back to the camper — it’s literally right down the block — and prep myself by pulling on my flight suit. I wear a tank top with it, so I can keep the top half of the flight suit off with the sleeves tied around my waist. It’s hot and humid here and I don’t want to sweat my brains out in a long-sleeved Nomex suit. I make sure all my documents and my sunglasses and the helicopter keys are in my pockets. I put on socks and comfortable shoes. If Alex the bird is outside, I bring him in. I also zip the bed windows closed so rain doesn’t get into the camper. I put a bottle of regular water and a bottle of “vitamin water” in my little six-pack cooler to bring along on the flight.

And then I wait.

The other day, I waited three hours. The second call never came. The first call had been premature and it never rained on the orchard. I had to call the grower to see if he thought he’d need me to fly. He didn’t. I was all dressed up with no place to go.

When the second call comes, I’m ready to go. I pull up the top half of my flight suit and zip up. I lock up the camper and drive back over to the helicopter. I take off the tie-downs (if they’re not already off), do a walk-around, and climb on board. I start the engine and get it warming up. Then I put on my helmet, set up my cell phone to receive calls in flight, and when the helicopter is warmed up, I take off.

The Orchard Block from Hell

I thank my lucky stars that I never had to dry this nightmarish block.

I use my GPS to fly direct to the orchard block. I’ve already scouted all the blocks on foot and by air, so I know how to approach. I come in low over one corner and settle down to 5 to 10 feet over the tree tops. Then I fly slowly down the row. At the end, I turn, move over a row or two — depending on the density of the trees — and fly back to the side I started on. I go back and forth like this at 5 to 10 knots groundspeed, being careful to avoid obstructions like wires, fans, poles, tall bordering trees, hillside rock outcroppings, and buildings. Some orchard blocks are easy to dry. Others are damn near impossible. Most fall somewhere in between — not too difficult to do, but not so easy that you can do it without paying attention.

Complacency can kill you — or at least destroy your helicopter and a bunch of trees.

You can read about my first time drying here.

Cherry Drying Isn’t for Everyone

I can’t tell you how many people have contacted me, asking me to help them get into cherry drying. Do these people understand the expenses involved? The skill level required? The dedication to waiting around for a phone call that may never come? I don’t think so.

I also don’t think they understand the competitive nature of this work. Right now, there are too many pilots for the available work. We’re all competing against each other for contracts. This year, a bunch of JetRanger pilots were so desperate for work that they undercut the rates of most other pilots — they were actually billing themselves out for less than R44s! How can we compete against that?

When the company I flew for part of the season last year fell apart this year, I had to scramble to get the contracts I have. While I got enough work for myself, I could handle more. It’s just tough to break into this work and build a reputation for yourself — especially if you don’t get a chance to fly and prove you can meet growers’ needs. I wasn’t able to prove myself last year and feel lucky to have the opportunity again this year.

And then there’s the skill level required to do this kind of flying. It’s not as easy as it seems — especially if conditions are less than perfect. Sure, any decent pilot should be able to hover slowly over tree tops. But for hours on end? And what if the wind kicks up and you’re dealing with a quartering tailwind as you travel in one direction? Or the block is full of obstructions, like power lines and fan poles? Or bordered by trees? Or there are storms in the area that you need to fly through to reach your orchard blocks?

Why do you think I wear a helmet and a Nomex flight suit when I fly?

No Flying Today

I worked on this blog post on and off all day. I watched the storm clouds build and move in the sky and on Doppler radar. I saw the scary yellow blobs of convective activity flare up and fade out on my computer screen.

It’s still cloudy, but if the radar can be believed, it’s not threatening rain over my orchard.

But it’s only 5 PM. There are still more than 4 hours left in my work day.

I’m Being Paid to Worry about the Weather

A funny true story.

The backstory: I’m in Washington State on cherry drying contracts. In short, I’m being paid to be on call to use my helicopter to dry cherry trees in case it rains. You can learn the details about this in “The Life of a Cherry Drying Pilot.”

Last night, my grower called around 9 PM. He was almost certain that it would rain at 4 AM this morning. He lives in Wenatchee and his orchard block is near Quincy, a 30-minute drive south. He wanted to give me a heads up. He said that he knew I wouldn’t fly in the dark, but if it rained, he expected me to be drying at dawn. I assured him that would be no problem and encouraged him to call me if he needed me, no matter what time it was. That, after all, is what he’s paying me for.

I was dead asleep this morning when my phone rang. My Blackberry’s ring tone is a digitized version of the classic analog telephone bell. Despite the fact that I’d heard that sound every day for the first 20 years of my life, when it rang this morning, I had no idea what it was. After all, I was asleep. When I realized it was my phone ringing just inches from my head, I grabbed it, pushed the answer button, and said “Hello.”

It was my grower. “I’m leaving Wenatchee now,” he told me. “The sky is clear.”

I wasn’t too sleepy to wonder why he was calling me to tell me the weather was good.

“I’m going to see what it’s like down at the orchard,” he went on.

I got the feeling he wanted a local weather report. After all, I was only 6 miles (as the crow flies) from his cherry trees. Fortunately, the zip-up window beside my head faced out that way. I unzipped it and looked out. I could see stars. It wasn’t raining. I couldn’t see any rain clouds by the light of the waning moon. I reported my findings.

“Well, I’m going down there anyway,” he said. “I’ll call you if it rains.”

“Sounds good to me,” I said. We said goodbye and I found the button that disconnected us. The phone reverted to clock mode. It was 3:50 AM.

I managed to get back to sleep for another hour before the birds woke me up for the day.

It’s nearly 12 hours later and it still hasn’t rained.

When I told this story to my husband, he told me I needed to have a talk with the grower. I told him I’d do no such thing. I explained that I was on standby and that the grower had paid me good money to worry along with him about his crop of cherries. If it made him feel better to wake me up to discuss the weather once in a while, that was fine with me.

As long as he didn’t do it every morning.

Parked at the Flying Service

Neighborly flying service folks let me park my helicopter on one of their tie-down spots.

Last year, when I was in Quincy for cherry drying season, I was fortunate enough to get a hangar for two months. Having a hangar can be a pain in the butt when you have a helicopter, but I was prepared and had my tow bar handy. Weather was [too] good and I didn’t fly much. It was nice to keep the helicopter out of the sun.

This year, I didn’t bother trying to find out if the hangar was still available. I doubt it is — someone else was moving in the day I moved out. And since I don’t have my tow bar with me, moving the helicopter in and out would be nearly impossible by myself anyway.

Quincy airport is about 4-1/2 miles from my living space at the Quincy Golf Course. That isn’t very far. But there were other, closer options for parking the helicopter. One was the Ferguson Flying Service right across the street from the golf course. I stopped by there on Monday, before bringing the helicopter in from Seattle, to see if I could park there. They very graciously said that I could.

Helicopter at Ferguson's

My parking space at Ferguson’s Flying Service in Quincy, WA.

So I’m parked on one of the concrete tie-down pads they used to use for their crop dusters.

For those readers who are not familiar with agricultural aviation, i should probably explain what a flying service is. A flying service is a company that provides crop dusters and related agricultural aviation services for farmers and growers. Quincy is farm country, full of wheat, corn, alfalfa, potato, and other crop fields, as well as fruit trees and even some grape vines. There are at least two flying services in the area. Each has its own scrawny paved runway and a small handful of crop dusters.

Helicopter at Ferguson's

Another view of my parking spot and the plane beside me.

Now, if you look closely at the biplane in these photos, you’ll probably notice that it doesn’t look “airworthy.” It’s not. For one thing, it’s missing it’s tail — or “tail feathers” as one of the local pilots referred to it. Its big radial engine also needs some work. It’s apparently bled out, too — the engine needs some serious TLC.

But Ferguson’s has other airplanes it flies. This one is parked until it’s repaired and ready to fly.

I want to thank the folks at Ferguson’s Flying Service for allowing me to park at their facility. It’s great to have the helicopter so close and it’s great to chat with the guys when I go over to check on it or prepare for a flight.
