Do you think this idea has any merit?

Automatic Landing Assistant
If I had half an engineering brain I would design the "ALAHA" (Automatic Landing and Hovering Assistant). This would be a great training aid for newbies and crap pilots.

It would have 2 modes - "Hover Mode" and "Landing Mode".

Basically, it would be a gizmo roughly the size of the gyro.

"Landing Mode" would be activated once the heli approached the ground (say 1.5m). It would stabilise the heli in a hover, point the heli into the wind, take over control of all the servo's, drop the headspeed to 1500 and then land your heli.

It would use technology similar to that of the current CoPilot for lateral orientation, and the Governor for the throttle, and then it would need some altitude sensing device to calculate height and rate of descent.

It could also be used to practice new tricks if you placed the ALAHA in "Hover Mode" instead of "Landing Mode". You might set a minimum ceiling of 25m. You then attempt your trick, and let's assume you fluff it completely. The ALA senses you have hit your 25m ceiling, and takes over control. The heli is bought upright, rises back to 25m, and goes into "Hover Mode".

Control is returned to the pilot once Hover Mode has been successfully established for 3 seconds and an input is sensed from the Tx.

Alternatively if the pilot is a bit shook up the ALAHA will hover your heli for up to 60 seconds to let you regain your composure. If you still have not assumed control, "Landing Mode" is activated and ALAHA lands your heli and shuts off the engine for safety reasons

You could call it Pilot-in-Charge instead of Co-Pilot.

Should work (in theory) and it would sell if the price was reasonable.

assuming it knows what is below it, wouln't be much good trying to land on a hedge

Sounds good in theory but i don't think it could be done, trying to automatically correct itself to land in that last foot or so with the groundwash buffetting the chopper around would be to tricky. But who know's if you lose control of a heli, it's going to come down somewhere, might as well have something to aim it for you

I don't have any experience with the current CoPilot, but I've been lead to believe that it doesn't work at low altitude when it can't "see" the horizon. This might be a problem....
