#1 SPEEDBRAKES von aetio 13.04.2008 22:31

looking to the real BAe146, when it's on final tail big speedbrakes are extended, while wings speedbrakes are retract . How can i do that, in our very good Bae Panel project aircraft?
Thanks for replies ;-))

Hi Ezio,

I think the best way is to use an axis for this. At about 3/4 travel the speedbrakes will be fully deployed and in the full position the spoilers will deploy as well, just like the real thing.

Hi Adrian,

as you can see on this VIDEO - wings airbrakes extend only when 146 is landed....Tail brakes instead extend when 146 is on final........
Best wishes ;-))

The flaps that lift on the wings are the 'Lift Dump Spoilers' , they destroy any lift that the wings produce, which is why they are only used on the ground.

The airbrakes are the conic section at the rear of the fuselage that opens outwards to slow the aircraft down, these can be deployed while the aircraft is still in flight, normally on approach.

By assigning an axis to the spoilers in FS, you will be able to control them correctly. i.e. 75% lever position will give full airbrakes and then once on the ground, you manually move the lever to 100% for full airbrakes and lift dump spoilers just like in the real 146.

N.B. The automatic deployment of the spoilers didn't come about until the ARJ's were built.

The airbrake can be used during flight and is deployed just before landing. The lift dump spoilers are not available in flight. Either 2 mains or 1 main and the nose wheel MUST be on the ground for the Lift dump spoilers to deploy, and even then there is a 6 second delay.

If the pilot commences a go-around once on the ground, the spoilers will automatically close. (2 throttle leavers must be at a high power setting). The air brake how ever doesn't.

Dont know if that helps explain the system?

G'Day Adrian

Thanks. Ive been helpin Mathias out for a while with the panel. But only recently made the forum account.

I enjoy explaining systems to people. I still have lots to learn myself (never ends!!!)
