HOW TO FLY A J-3 CUB

SOME AIR WORK

Ok, your first takeoff went pretty well and your wondering why you read all this crap when nothing scary happened, piece of cake. Your probably amazed at your speed and the fact that a plane can fly this slow and wondering if you have enough fuel to climb to two thousand feet. Not exactly a performance tiger but hey, this is kinda fun. Neat being able to fly with doors and window open...yea, this is fun.

Head on out to the practice area and do some turns, keep that ball in the middle (try to keep the ball in the middle). Relax and have some fun. Enough fun, your instructor wants to do a stall (They always want to do that. What is it with instructors? What's the big deal with a stall? I don't like stalls) Let's face it, stalls are about as much fun as a certified letter from your x-wife.

I hear you, the big deal with a stall is that it can turn into a spin. I am not going to go into my full stall spin lecture but a few things are worth reviewing as they apply to the Cub. The Cub will spin! The Cub has a narrow speed band. In other words, you don't have a large window between stall speed and cruise speed. The Cub does not have some of the inherent stability or stall dampening characteristics of later modern trainers. A lot of people have been killed in J-3 Cubs in stalls and spins. I knew a few.

Your instructor knows that if you don't stall you can't spin. He also knows that you have been trained in stall recognition and recovery. He knows you have been trained to avoid stalls. He also watched the airspeed get down to 45 mph on your takeoff with the ball off to one side. Humor him, it's for your own good. Here's how to make your instructor happy and avoid spending the rest of the day practicing something that you don't like (and scares you...just a little bit) . Pick a point on the horizon that you can see with the nose up. A mountain or perhaps a nice cloud. Check to make sure your not dragging a wing, wings level. Center that ball, I say again, center that ball because this is the main thing he's looking for. As you increase your angle of attack keep the nose on the point you picked with the rudder. If it strays off to one side, bring it back and keep it there. If you have done all this, the airplane should stall pretty much straight ahead and your instructor is so happy you move on to other things more fun. If the nose breaks a little to one side, use the rudder to bring it back in conjunction with your normal recovery. Happy instructor. If you use the ailerons to try to steer the nose back get ready for a long lecture and more stalls.

Realistically, most accidental stalls do not occur in the manner that we practice them. The wings are probably not level, the ball is not centered and the power may not be at idle, and of course if you stalled by accident, your not ready for it. Personally, I like to demonstrate to the student what will happen in various stall conditions. I demonstrate a normal straight ahead stall. (No big deal). A stall from a slip (hmm, she broke over the top, that's interesting). And a stall from a skid. (Oh @#$%! What happened!) A stall from a skid, this is the one that makes you a believer in centering that ball. This is the one that helps you understand why you have been chided from day one for not centering the ball. This is why it is important. This is the one that will get you into a spin. In short, this is the killer. Now, a word of caution: A stall from a skid is what I call and approach to a spin. A lot of people have been killed in Cubs practicing spins. If you have confidence in your instructor then ask him to show you this one. It will certainly make a believer out of you. If your instructor is your brother in law Vern, who said he flew a Cub once you shouldn't be there in the first place. Know your instructor. The FAA removed spin training from the curriculum a long time ago (because too many people were getting killed in spins). Instructors are required to demonstrate a series of spin entries and recoveries to get their ticket but that may also have been a long time ago and in a different kind of trainer. Spins can go bad for a variety of reasons. In short, don't screw around with this yourself and if you want to see it ask somebody who is well respected and documented to show it to you. Remember the most dangerous words in aviation "Watch this". One of my acquaintances was going to show his girlfriend what a hot pilot he was by spinning a J-3. Killed them both. Enough said, keep that ball centered and the nose straight on the stall and everybody is happy.

One of the keys to being a good pilot is being able to coordinate the controls and make nice smooth turns. Student pilots spend much time and effort trying to please their instructors by synchronizing the ailerons and rudders. This is as it should be. But, one of the keys of being a good pilot is being able to use the controls independently when required. In a tail dragger this becomes more of an issue. The two following maneuvers will help you learn to use the controls independently. Progress made here will be a valuable asset overall but especially helpful when we start dealing with crosswinds.

DUTCH ROLL

Relax, it's not a full roll your not going to get turned upside down. Just a series of small turns where you don't really turn. Pick a point over the nose. Make a little turn to the right but before the plane actually starts to turn, go left. The idea is to bank the wings from side to side, keeping the nose on the point. This really gets funny because it is a lot harder than it looks and you'll find yourself yawing all over the place. No, you didn't? Try a steeper bank. Woaa!!! Told you. You thought keeping the rudders and ailerons synchronized was the ticket but it didn't work did it? That's why this is a good maneuver. Although it is a coordination maneuver, you will find that it won't work unless you learn to operate the rudders and ailerons as independent devices. The ailerons may be one way, the rudders the other but the nose stays on the point. If your instructor is laughing at this point, ask him (or her) to do it only faster at a steeper bank. Who's laughing now? This is one of those things I use to see how much trouble we are going to have later (and as a gauge of much experience a a pilot has). If the student does good Dutch rolls my job is much easier.

DRAWING A BOX

I borrowed this from the glider guys but it is an excellent maneuver to practice getting the hang of independently using the all of the controls. Start from straight and level cruise. Pick a point. Keeping the wings level, draw a box around the point with the nose. Up, right, down, left, you know, a box. Again, harder than it looks. Keep those wings level! Tired of that, ok, now make a circle. Remember, all this practice pays off soon when we start working on landings.

SLIPS

Now might be a good time to practice your slips. Slip, remember that thing you learned a long time ago to help get you down in case your flaps didn't work. A J-3 does not have flaps. Another cross control maneuver where you use the rudder and ailerons independently. Everybody has a favorite side. Practice them both ways because the text book way to slip for landing is into the wind. A common mistake in a landing slip is to let the airspeed get too low, remember to lower the nose to maintain speed.
