Upwind and downwind throttle compensation

[julioall]

Hello everyone!

Here is a problem I've been dealing with lately. I'm flying at ~300m ASL and sometimes my aircraft will be facing some winds about 20-30 kph. Since I'm doing photogrammetry missions, when flying upwind ground speed is decreased therefore more pictures are taken. In the other hand, when flying downwind ground speed is increase and less pictures are taken.

Here is the question: Is there a way for GP2 to compensate and have a constant ground speed when facing winds?

I thought about the auto throttle but seems like is not working for this or perhaps I'm missing something.

Thanks for your help. Cheers!

Hi Julio,

I have the same issue and the best solution is auto-throttle control but you must be sure that your flight lines are not parallel with the wind direction but perpendicular .

The downside of this option is the turn sharpness at the end of flight lines : the turns from one side will be very good and the others will be overturning , so you must take into consideration this when doing the flightplan.

Try this on a flight and check if it works.

Hi,

Gluonpilot combines altitude and speed to steer the throttle. If it is too slow (compared to the defined minimum and cruise speed) throttle should increase.

But indeed:
You should arrange your flight plan that you fly perpendicular to the wind, and the plane flies into the wind when it turn to the next line. This ways the turning circles are small.

That is dangerous! Any crosswind will result in unstability, aerodynamically speaking.

Do you guys have any experience doing this with flying wings?

By the way Tom, I sent you a PM. Hope you find the time to reply.

Thanks guys!

Sorry I only fly flying wings. Never had any instability in crosswinds.

I am flying 2 wings : Skywalker X5 and a FX-61.
