Airspeed offset

[dcmoore2]

Hi Pete,

I hope you had a good holiday.

I am trying to write the airspeed offest into FS 2004. I am wanting to set the airspeed of an aircraft so I can generate a scenario between two machines without having to go into the Map menu and set all the variables in there. I have managed to get the altitude set and the position and I am trying to set the airspeed but without much sucess! I have tried to write to the offsets 02B4, 02B8 and 02BC with no sucess, I have found that by writing to the 07E2 offset that I can get the autopilot to the right speed but actually seting the aircraft directly to the speed is proving tricky!

I was wondering if you could help? Do I have to write to all of the above offsets, or is there a dominate one that would alter the others accordingly?

Thanks in advance for you help.

I don't recall the exact offset address, but check in the 3050 - 3090 range. The speed values in that range are the one's you need to set.

I'm afraid we've never discovered how to set the airspeed directly. The offsets for this are *results* of computation, and will simply get overwritten on the next cycle. There are some velocities, accelerations, etc, in the 3000 + area which do certainly have an effect, but not precise and not maintained unless you keep writing fast enough.

Even in FSX, where the facilities are already a little more comprehensive in this area, the only sure way of setting the airspeed is by an effective "restart", where the position and attitude are also needed and it it nearly as slow as loading a new flight.

Pete & Doug,

Thank you both for your very prompt reply, I will research into the 3000+ area and try to set it there.

I did find a work around though. I found that even though it take a while to settle, setting the Autopilot, with throttle control, to the correct speed the aircraft will achieve the desired speed!

Thanks again for the help and the support
