Practical purposes of comm maneuvers?

[Horizon]

I believe the chandelle was originally intended as an escape maneuver if you find yourself in a boxed canyon.

For the boxed canyon, the ultimate escape maneuver is the hammer-head stall...

I perfer a split-S or a Immelman, I forget which goes up?

...and for instrument let-downs, the spin

You know that's probably a BIG reason for it - before working on my commercial, about the only time I used the pedals is when taxiing.

You had a crappy instructor.

And GKrangers, if you don't have a PTS, you're starting off on the wrong foot. That should be the first thing you read before whatever stupid Jeppesen/ASA/King maneuvers manuals your instructor makes you use.

And the Chandelle was originally used in WWI to escape enemy ground fire.

As far as box canyons go, I prefer the 1/2 turn spin. Certainly easier than an immelman or hammerhead.

The commercial maneuvers help to perfect your flying skills. Yes, I admit that they are stupid, but they really do make you gain a better feel for the airplane.

Let me add a bit to this. As an airline pilot (if this is your goal) you want to be smooth on the controls to the extreme. Consider this - sloppy rudder control in a c152 is barely noticed. Fly an aircraft 30 to 75 ft long and passengers in the last row really feel it! Paying customers be it an airline, or charter expect perfection. As crazy as these maneuvers sound now, being proficient in doing them is gonna pay off - trust me. Hope that adds another explanation.

I prefer overflight at FL390 or above.

Chandelle: The objective of this maneuver is to develop the pilot's coordination, orientation, planning, and feel for maximum performance flight, and to develop positive control techniques at varying airspeeds and attitudes.

Lazy Eight: The objective of the lazy eight is to develop the pilot's feel for varying control forces, and the ability to plan and remain oriented while maneuvering the airplane with positive, accurate control. It requires constantly changing control pressures necessitated by changing combinations of climbing and descending turns at varying airspeeds. This is a maneuver often used to develop and demonstrate the pilot's mastery of the airplane in maximum performance flight situations.

Taken from FAA-H-8083-3 (Airplane Flying Handbook, since you probably don't have one)

There mainly to see how smooth and accurate you can fly the aircraft. Also to see how well you can keep the plane coordinated.

I've got one.

I've got one.

Then read it. Believe it or not, there's actually some good info in it. Like, oh I dunno... something like the purpose of different types of maneuvers.

So what is a "maximum performance flight situation" that I might use a Lazy eight in?

I can see in the statement you quoted why they're in the PTS...but is that the only practical purpose? To pass the "practical" test? If so, that's pretty weak.

The Airman instructors always told me, however, that the purpose of the maneuvers was to pass the checkride...take that for what its worth though.

Everyone has forgotten the most important reason for doing the commercial manuevers: Giving your instructor the chance to work for a couple hours and make some money so he can afford to buy a tank of gas and a jar of peanut butter.

DOH! I knew I missed a few questions in the oral....darn it...

Yeah, this is one of those things that only comes with experience. Now where did I put my peanut butter?
