Making Panoramas

Not bad, but I’m not ready to buy yet.

I spent part of Sunday afternoon in Sedona, AZ, on top of a red rock with about 270° views of the red rock cliffs around me. I was playing with panoramic photography.

I’d just bought a new tripod head for my camera. I wanted a ball head set up with a swivel base for panoramas. That means compass points marked off for precision panning. I wound up with another Manfrotto, which makes sense because the tripod is Manfrotto, too. It cost about twice what I wanted to spend, but I figured that between it and the tripod head it was “replacing” I’d have all the tripod heads I’d ever need.

Anyway, I was experimenting with panoramas shot with the camera held vertically, in portrait view. Most folks don’t think of doing panoramas that way, but if you want great big finished photos, you need to maximize your pixels. Do the math. My 10 megapixel Nikon D80 shoots photos that are 2592 x 3872. Shoot that vertically, and your panorama becomes nearly 13 inches tall at 300 dpi. That’s 5 inches taller than if the photos are shot in landscape.

Of course, the drawback is that you need to stitch more photos together to get the final image. Like this one, which is 8 images:

Sedona Panorama

In case you’re curious, the images in this panorama were shot with a 50mm focal length (that’s a 75mm equivalent for standard 35mm film cameras, if that matters anymore). All the shots had the same exposure: f6.3 at 1/160th second. The tripod head was rotated at 15° increments. If you’re looking for a seam, you won’t find one — not even in the full sized image.

This represents my first stitching attempt with Panorama Maker 5, a Mac OS application by ArcSoft. Panorama Maker takes a lot of the guesswork out of creating panoramas by automatically identifying shots taken around the same time (and likely to be part of a panorama) and handling the stitching for you. Just click a photo in its browser and it selects the shots that go with it. Tell it what kind of panorama you want, and let it get to work.

I ran into frustrations with the software immediately. For this particular panorama, even though the software’s browser recognized the images as vertical shots, the stitching component wanted to turn them all sideways before stitching. This would basically attempt to stitch the top of one shot to the bottom of the next. I couldn’t find a way around this — at least at first. But then I just told it to create a vertical panorama. I saved the resulting image and opened it in Photoshop, where I rotated it 90°.

Later I realized that if I used the software to rotate the images 90° and then rotated them back, it properly recognized them for a stitch. Personally, I don’t think that step should be required. I think the software should stitch photos in the same orientation they appear in the browser. Period.

I also tried a 360° panorama. The images were great (if I do say so myself) — 24 shots taken at equal intervals using a tripod with manual exposure settings. The software had a lot of trouble with it. It failed on several attempts and when it finally succeeded, one of the images was shifted way higher than it should have been. I had to manually edit the match points on one shot. That fixed things, but it really did take forever (or almost) on my old 15-inch MacBook Pro, which is what’s with me on this trip. At one point, the fan was screaming. And the resulting QuickTime movie looked like the first effort that it was. (You can click here to download it; didn’t think it worth embedding in this post.)

Panorama Maker is try-before-you-buy software and the folks that make it don’t time-limit it. Instead, they display the usual annoying reminder and limit save size to 1/16 of full size. Perfectly fine for testing purposes. It costs $70 to buy and I’m not 100% sold on it because of the problems discussed here. When I get time — if I ever get time again — I’ll try it on my iMac back at home. I suspect it’ll be a bit quicker and not have to wheeze to get the job done.

If I see any improvements, I’m sure I’ll have more panoramas to show off here.

In the meantime, I’d love to get comments from readers about solutions they’ve found that work on Mac OS.

Going Around

Complacency leads to sloppy flying.

I did a go-around today when landing in Sedona.

It was the second go-around I did in just over a week.

If you’re not a pilot, you might be wondering what I’m talking about. A go-around is a flying maneuver you perform when you realize that you’re botching up a landing beyond what you can smoothly — or perhaps safely — fix.

[To be fair, sometimes it isn’t the pilot doing the go-around who’s botching up the landing. Sometimes the tower tells a pilot to go around when the plane that landed before him is still on the runway. I was in a commercial airliner that did a go-around because of that. There are lots of reasons to do a go-around, but I won’t lean on any of those.]

In both cases, I was expecting a routine landing and simply wasn’t paying as much attention to what I was doing as I should have been.

Last Saturday it was while landing at a helipad at a rides event. I came in too high. If I’d been alone on board, I could have made the landing safely by simply descending from a high hover. But I had three passengers on board and enough fuel to put us right about at max gross weight. I could easily see myself running out of power in an out-of-ground effect hover with that crosswind. Why fight with it? I went around. I joked with my passengers that they were getting a half landing for free.

N630ML

N630ML at Sedona Airport.

Today, I think my brain was out to lunch while I made my approach. The AWOS reported that the wind was 170 at 17 gusting to 28. I came in almost parallel to runway 3. What was that all about? The gusty quartering tailwind had me fishtailing all over the place, dancing on the pedals as I tried to make the pad. All the time, I’m pulling more and more collective. I knew I’d run out eventually — like the guy who landed his R44 there in a bush. So even though I was only 25 feet off the ground, I pushed the nose forward, gained speed, and flew out of there. I came around in on the taxiway parallel to runway 21 (duh-oh!) and had a smooth landing, despite the gusts.

Although I’m not happy about having to go around, I’m glad I had the presence of mind to do so. Too many pilots try too hard to make a sloppy landing work. That’s where you get hard landings, bent rotor blades, chopped off tail cones, and mangled helicopters.

But today’s go-around was a real wakeup call for me. It reminded me that I’m probably not thinking as much as I should be when flying. I’m at about the 2200 hour mark and complacency is rearing its ugly head.

Flying isn’t automatic; there is thought involved. Any “routine” landing can go south at any time for any reason. I should always be prepared. I should see problems before they become problems.

And there’s no excuse for sloppy flying.

So I’m scolding myself, publicly. And I’m hoping a few more experienced pilots scold me, too. (Try to be gentle, though, okay?)

I don’t want to be involved in an accident that gets linked to from someone else’s blog.

Yes, I’m Still Among the Living

And do I hate deadlines!

I’m too busy to blog, so don’t expect much here. I finished a book and immediately flew to Ventura, CA to record a video course. I’m in a soundproof booth all day long. Then I go to my hotel and sit at a desk in front of two laptops, preparing for the next day’s recording sessions.

I’m even too busy to tweet!

On Saturday, I fly home. Then, on Sunday, I start another 6-day helicopter excursion.

Since I apparently haven’t posted anything for at least a week, I thought I’d send this just to let everyone know I’m still alive.

Maybe I’ll have time to blog next week.

How to Become a Helicopter Pilot, Part II: The Big Tests

I want pilots to know what they’re doing — and prove it.

In the first part of this post, I explained the prerequisites to taking the tests you need to take to become a pilot. If you haven’t read that yet, read it now.

In this part, I’ll tell you about the two tests: the knowledge (AKA “written”) test and the practical test (AKA “check ride”). You’ll also find a few links to useful resources to help you pass them.

Written Test

The first of two tests you must pass to become a helicopter pilot is the knowledge test, which is also known as the “written test.” This is the test that has Stu — remember the blog reader from Part I? — so worried.

The written test is proof that you understand all the things you learned in ground school. If you don’t know or understand these things, you won’t pass the test.

The written test isn’t really a written test. It’s a multiple choice test with four possible answers per question. You can get a study guide that actually lists all the questions with their answers. This is possibly the best way to cram for the test — if you like to cram. It’s not the best way to learn the material, though.

Want to see what’s on the test? Download all the questions.

Want to learn? Talk to a flight instructor and other pilots. Watch the videos. Read the AIM. Read articles in Vertical, Rotor & Wing, HeliNews, and even Flight Training. Visit blogs and forums where experienced pilots discuss flying issues. Ask questions; listen to answers. Hang out at airports. Buy a scanner and listen to the local airport chatter.

The written test and ground school knowledge are important . It makes me very sad that Stu (and so many others like him) isn’t taking it as seriously as he should. After all, the first time he gets hit with LTE in a hover, is he going to know how it’s caused and what he can do to stop it? When he does a photo flight with a fattie on board on a hot day in that R22, will he know how to avoid settling with power? Will he understand the danger of thunderstorms or virga or what a lenticular cloud means? Will he know what to expect when flying close over the top of a mountain ridge with a tail wind? Will he be able to read a chart well enough to keep out of a restricted area or learn whether military operations in an MOA affect his operating altitude? Will he bust Class Bravo airspace because he doesn’t know which magic words from ATC grant him entry? When the clutch light flickers on in his R22, will he know what to do?

How can anyone consider himself a pilot if he doesn’t possess the basic knowledge required to be a pilot? Passing a multiple choice test about the basics of flying the aircraft is the least a future pilot should be required to do.

And you must pass the knowledge test before you can move forward to take the big test. FAR Part 61.39, “Prerequisites for Practical Tests,” starts with:

(a) Except as provided in paragraphs (b) and (c) of this section, to be eligible for a practical test for a certificate or rating issued under this part, an applicant must:
(1) Pass the required knowledge test within the 24-calendar-month period preceding the month the applicant completes the practical test, if a knowledge test is required;
(2) Present the knowledge test report at the time of application for the practical test, if a knowledge test is required;

It’s a really good idea to take and pass the knowledge test as soon as you get the required endorsement. It gets a big part of the learning process out of the way, clearing your mind so you can concentrate on the flying and use your knowledge to understand how the flying works.

It also starts a clock ticking: once you pass, you have just 2 years to take and pass practical test. Otherwise, you’ll have to take the written test all over again. How’s that for a motivator?

Check Ride

Once you’ve met all the other requirements above and have passed your written text, you’re ready for the practical test, which is better known as a “check ride” or “check flight.” The practical test is administered by a special examiner who is authorized by the FAA. In some instances, it might be a CFI at your flight school. It could also be someone who works directly or indirectly for the FAA.

I personally believe that a check ride with the FAA or an examiner not employed by your flight school is a better check ride. Your flight school has too much riding on your test and might pass or fail you based on any number of factors other than your knowledge or ability.

Did you pay a flat fee for all your training with a guarantee of completion with a set number of flight hours? Are you near the end of that time? What’s the flight school’s motivation? Do you really want to become a helicopter pilot if you’re not ready? Sadly, a now-defunct flight school that passed too many students before they were ready has gotten a reputation for it. Many of those students, now pilots looking for jobs, aren’t even getting interviews.

Don’t Get Milked!

In 2001, I was ready to take my commercial check ride. My CFI signed me off just before he left for a job at the Grand Canyon. But my new CFI, following instructions from the chief flight instructor, claimed I couldn’t perform the most basic of maneuvers. They refused to give me a stage check I needed to get an endorsement for my check ride. Shocked, I left the flight school and went to another. I took and passed my check ride after only 10 days there.

It was pretty obvious that the first school wanted to keep my $200/hour of dual flight revenue flowing in as long as possible.

Or perhaps the flight school’s enrollment is down and they need your hourly dual rate revenue to pay their bills. What’s the flight school’s motivation? Do you really want to keep financing your flight school?

Before I go any further, I should remind you that before you take your practical test, you need to meet the rest of the requirements of FAR Part 61.39, “Prerequisites for practical tests.” I won’t quote them here; use the link to read them for yourself. In general, no good flight school will sign you off until you meet these requirements. If they do and you go to take the test, you’re likely to have the test stopped before it gets going. That would be a real embarrassment, because it would show the examiner that you didn’t bother to read Part 61.39 and have wasted his time.

The practical test is actually two tests in one. The first part is an oral exam, where the examiner asks a bunch of questions he thinks you need to know answers for. These are usually the same questions covered in the written test — but there’s no multiple choice crutch to lean on. There are also questions specific to the helicopter you’ll be tested in. Better know the engine horsepower, RPM limits, emergency procedures, fuel capacity, best RPM and speed settings to extend your range in autorotation, and just about anything else in the POH. This part of the test can be as short as an hour or as long as three or four. It depends on the examiner and how confident you can make him about your knowledge.

Once the oral part is finished, the flight part begins. FAR Part 61.43, “Practical Tests: General Procedures,” gives a good idea of what the goal is. It starts with:

(a) Except as provided in paragraph (b) of this section, the ability of an applicant for a certificate or rating issued under this part to perform the required tasks on the practical test is based on that applicant’s ability to safely:
(1) Perform the tasks specified in the areas of operation for the certificate or rating sought within the approved standards;
(2) Demonstrate mastery of the aircraft with the successful outcome of each task performed never seriously in doubt;
(3) Demonstrate satisfactory proficiency and competency within the approved standards;
(4) Demonstrate sound judgment; and
(5) Demonstrate single-pilot competence if the aircraft is type certificated for single-pilot operations.

This is the meat of the matter. Does the pilot know what he’s doing? Can he prove it beyond doubt?

The flight part of the test usually includes preflight inspection with questions, examination of aircraft documents, and the flight itself. Then you fly. From the moment you step in to the moment you step out, the examiner is watching you. If he thinks, for even a moment, that you’re unsafe or don’t know what you’re doing, he’ll fail you. If you scare the crap out of him — or even make a big boo-boo — he’ll stop the test.

Pass it and you’re a pilot.

And That’s All There Is to It

Yes, the heading is a joke. Getting a pilot’s license is not easy. But should it be?

Let’s face it: a pilot flies aircraft over the ground. If he screws up and crashes, he can kill innocent people on the ground as well as his passengers. It’s a heavy responsibility. Don’t you want pilots to know what they’re doing? I do.

Flying is not something to be taken lightly. Want proof? Search this. I’d say that 95% of aviation accidents are due, in one way or another, to pilot error. Don’t think so? Read the reports. I do.

My message for “Stu” is this: If you want to be a pilot, get serious about it. Study hard, learn what pilots need to know. Stop making excuses. Put up or shut up.

Because the last thing the world needs is another “lazy” pilot.

How to Become a Helicopter Pilot, Part I: Before the Tests

It can’t be too easy, can it?

A few weeks ago, I got this e-mail message from a blog reader. In an effort to keep him anonymous, let’s call him Stu (short for student). Here’s what he had to say:

Perhaps you could post an article about the difficulties of initial licensing. I have some 40+ hours of instruction and believe I can fly a R22 quite well. My problem is the written test. I just can not get my arms around studying for and taking it. Partially due to time constraints, partially due to me being much better at practical things than book learning.. and partially of course, laziness.

I know I have to do it.. I just procrastinate a lot and simply have not gotten around to studying.. nor of course taking the test itself.

Any words or advice, thoughts, inspiration (LOL).

I wrote back, telling him that he’d just given me a topic for a blog post. I finally have time to write it.

So allow me to explain what you need to do to become a private helicopter pilot. In this first post, I’ll talk about the pre-test requirements. In the second part, I’ll talk about the tests and link to some useful resources that can help you pass them.

Hours

There’s a lot in that e-mail message, so I’ll start at the top. Stu says he has “some 40+ hours of instruction” and believes he “can fly an R22 quite well.” That’s great. If it’s true, it also makes him a better than average pilot. Most pilots need at least 60 hours of flight time before they’re proficient enough to take a check ride.

FAR Part 61.109, “Aeronautical experience” states, in part:

(c) For a helicopter rating. Except as provided in paragraph (k) of this section, a person who applies for a private pilot certificate with rotorcraft category and helicopter class rating must log at least 40 hours of flight time that includes at least 20 hours of flight training from an authorized instructor and 10 hours of solo flight training in the areas of operation listed in Sec. 61.107(b)(3) of this part, and the training must include at least–
(1) 3 hours of cross-country flight training in a helicopter;
(2) Except as provided in Sec. 61.110 of this part, 3 hours of night flight training in a helicopter that includes–
(i) One cross-country flight of over 50 nautical miles total distance; and
(ii) 10 takeoffs and 10 landings to a full stop (with each landing involving a flight in the traffic pattern) at an airport.
(3) 3 hours of flight training in preparation for the practical test in a helicopter, which must have been performed within 60 days preceding the date of the test; and
(4) 10 hours of solo flight time in a helicopter, consisting of at least–
(i) 3 hours cross-country time;
(ii) One solo cross-country flight of at least 75 nautical miles total distance, with landings at a minimum of three points, and one segment of the flight being a straight-line distance of at least 25 nautical miles between the takeoff and landing locations; and
(iii) Three takeoffs and three landings to a full stop (with each landing involving a flight in the traffic pattern) at an airport with an operating control tower.

The short version of this is that to be a private helicopter pilot, you need 40 hours of flight time, of which 20 must be dual, 10 solo, and 3 cross-country. Stu might meet this requirement.

Training

It isn’t enough to have the hours you need to be a pilot. You must also meet the requirements of FAR Part 61.107, “Flight Proficiency.” It points out, in part:

(a) General. A person who applies for a private pilot certificate must receive and log ground and flight training from an authorized instructor on the areas of operation of this section that apply to the aircraft category and class rating sought.
(b) Areas of operation.

(3) For a rotorcraft category rating with a helicopter class rating:
(i) Preflight preparation;
(ii) Preflight procedures;
(iii) Airport and heliport operations;
(iv) Hovering maneuvers;
(v) Takeoffs, landings, and go-arounds;
(vi) Performance maneuvers;
(vii) Navigation;
(viii) Emergency operations;
(ix) Night operations, except as provided in Sec. 61.110 of this part; and
(x) Postflight procedures.

This means it isn’t enough to just get 40 hours that meet the requirements of Part 61.109. You must also get training on all of these areas from an “authorized instructor,” or CFI. If Stu went to a reputable training organization to get his flight training, he might meet all of these requirement’s too.

Ground School

Aeronautical knowledge or “ground school” training is also required, although the FAA does not specify a minimum amount of time. This training helps a pilot understand the important part of flying: aerodynamics, aircraft operations, communications, weather, navigation, flight planning — the list goes on and on.

FAR Part 61.105, “Aeronautical knowledge,” gets pretty specific when it states:

(a) General. A person who is applying for a private pilot certificate must receive and log ground training from an authorized instructor or complete a home-study course on the aeronautical knowledge areas of paragraph (b) of this section that apply to the aircraft category and class rating sought.
(b) Aeronautical knowledge areas. (1) Applicable Federal Aviation Regulations of this chapter that relate to private pilot privileges, limitations, and flight operations;
(2) Accident reporting requirements of the National Transportation Safety Board;
(3) Use of the applicable portions of the “Aeronautical Information Manual” and FAA advisory circulars;
(4) Use of aeronautical charts for VFR navigation using pilotage, dead reckoning, and navigation systems;
(5) Radio communication procedures;
(6) Recognition of critical weather situations from the ground and in flight, windshear avoidance, and the procurement and use of aeronautical weather reports and forecasts;
(7) Safe and efficient operation of aircraft, including collision avoidance, and recognition and avoidance of wake turbulence;
(8) Effects of density altitude on takeoff and climb performance;
(9) Weight and balance computations;
(10) Principles of aerodynamics, powerplants, and aircraft systems;
(11) Stall awareness, spin entry, spins, and spin recovery techniques for the airplane and glider category ratings;
(12) Aeronautical decision making and judgment; and
(13) Preflight action that includes–
(i) How to obtain information on runway lengths at airports of intended use, data on takeoff and landing distances, weather reports and forecasts, and fuel requirements; and
(ii) How to plan for alternatives if the planned flight cannot be completed or delays are encountered.

So it isn’t enough to know how to fly the aircraft. You need to know all the other things that are part of being a pilot. That’s what ground school is about.

There is a way to complete ground school quicker, more conveniently, and probably more cost-effectively: buy a video training course. I used the King Schools course for my primary training as a way to supplement ground school. John and Martha may be among the most corny and/or boring people on the planet, but they do cover all the basics very well. When I used the course back in the late 1990s, it came with a certificate that can could be used as certification that I’d completed ground school training. (Remember that the FAA says a “home study course” is okay.) Of course, your CFI won’t sign off on you unless he knows that you’ve covered all that material and understand it, so don’t be surprised if you still need additional ground school after watching all those videos. Still, when I took the written test right after watching the videos for days on end, I passed easily with a 94.

Endorsements

Before I go any further and start talking about tests, I do need to comment on endorsements or “sign offs.” To solo, you need an endorsement. To take the written test, you need an endorsement. To take a check ride, you need an endorsement.

What is an endorsement? It’s a signed and dated note in your logbook that confirms you’re ready to do whatever the endorsement is good for: solo, take the written test, take the check ride.

Who gives you your endorsements? Usually, it’s your flight instructor, but in some instances, it could be another CFI at your flight school. Good flight schools often require you to take a “stage check” with another CFI before getting an important endorsement. This helps prevent an ineffective CFI from pushing a student forward when he’s not ready. It also helps identify ineffective CFIs and unprepared students.

This is the gotcha that a lot of student pilots don’t get. It isn’t enough to have the 40 hours and meet the requirements of Parts 61.109, 61.105, and 61.107 quoted above. You also have to be able to prove that you have the knowledge you need to pass the written test and that you can perform the maneuvers you’ll be required to perform on a check ride.

And in the real world, 40 hours usually isn’t enough flight time to get the endorsements you need to move forward.

Up Next

In the second part of this article, I’ll tell you about the two tests you need to take and pass to become a private helicopter pilot. I’ll also provide links to some resources you might find helpful for preparing for — and hopefully passing — these tests.
