AutoPilot VS

[Badger]

Dear Pete,

Is it possible for FSUIPC to alter the default VS in the autopilot, in the same way you can force the Nav radio's to increment by 50Hz?

I'm trying to get Concorde to creep up to FL50 etc but the default VS of 100ft/min is TOO much.

I'd like to automate it, so I can use Radar Contact at the same time. I could use OTTO to maintain control and still nip out for a coffee :)

No. I think that is defined in the AIR file. It may be overridable in the AIRCRAFT.CFG file.

Creep up to 5000 feet? Use the afterburners for take off and point the nose to the sky on rotation! It will reach 5000 feet before you know it! :D

but the default VS of 100ft/min is TOO much.

100 fpm is the default? Surely not? Even a Cessna defaults to several hundred feet per minute. I know nothing which defaults to 100 feet per minute -- that's only a little over 18" per second! I can go up stairs faster than that and I'm 60 years old with no jets attached! :)

Anyway, the V/S you need will be completely different at different altitudes. You should not leave it (cannot leave it!) to any "default", you have to set it using the V/S setting for the A/P.

Pete

Hi Pete,

I think my message is a good example of why its never a good idea trying to write something quickly before going to a bonfire:)

I meant 50,000 ft

100 fpm is the default? Surely not? Even a Cessna defaults to several hundred feet per minute.

I should have explained this a little better. The Aircraft.cfg can determine what the initial setting is e.g.1800. I've found that. But if you want to reduce or increase this, it goes up or down in 100ft steps. Therefore the lowest setting is 100ft/min. Even if I edit the Aircraft.cfg to make it read 50ft/min for the initial setting, it defaults to 100 incremental changes :(.

Of course you are correct that the V/S changes during different stages of flight. Concorde has to be one of the most extreme examples. I wanted to use 50ft/min at the very end of her climb as she tries to approach Mach 2.02, but it looks like your saying its not possible anyway.

Oh well, I'll continue to nudge the trim wheel :)

Thanks again.

I think the granularity is 100 fpm, and I don't see any way to change it. Sorry.
