Re: What is "lift"?

I need to hear about gliders with thrust. Tell me more.

Is there a diagram in Dynamics of Atmospheric Flight that illustrates the balance of Lift, Drag, Thrust and Weight for specifically for a glider? If so, could you post a scan or picture of it?

Re: Sometimes the turnback is too successful

Whatever mnoeuvre you’re planning to do, make sure you’ve practiced it ahead of time. 500agl with no power isn’t the time to be experimenting to find out what the plane you’re flying is capable of.

Re: Use of VFR flight plan?

I'm thinking controllers with the system could look up VFRs routing informations and plans as they give the squawk code on their departure airport but maybe too busy??? Actually they do exactly that, at my home airport. Gave me a bit of a shock the first time, but you get used to it. "ground, C-ABC...

Re: Is the Class C Control Zone at Langley Airport Dysfunctional?

Whereas pilots are famous for their largesse and their unconcern about their paycheques.

Re: Lock Those Controls

Parked on the ground you could theoretically get strong tailwinds creating forces you wouldn't encounter in flight. Loads on control forces in flight are often kept low with trim anyway. You're rarely flying more than 6 hours at a time in the average airplane, so after that the forces relax. I coul...

Re: Lock Those Controls

Making the entire control system withstand whatever loads the flight controls could transmit back to the control wheel/stick, just abuses the whole system. You have a point, but the loads transmitted this way are no different to the in-flight loads, for which the system is designed. And at least yo...

If you want to annoy your instructor a bit more, ask him if the tail on a plane generate an upwards or downwards force :)

Absolutely, if you can take three months away from home/work. And if you can do it now, while the weather is ok. And if you can find a flight school that has availability and will cooperate with your plans.

Re: What is "lift"?

It goes against all spin training I've ever been taught. The only spin recovery you should have been taught is to follow the procedure listed in the Approved Flight Manual for the aircraft you’re flying at the time. If the flight manual says to use into-spin aileron, then that’s what you should do.

The law does not permit a freelance instructor to teach in her own plane. You and your son will have to buy your own plane for his training, or he will have to attend a Flight Training Unit. In theory you could contract with a flight training unit to send an instructor and one of their planes to you...
