Fokker 70 warning light
« on: December 18, 2006, 08:59:46 pm »
Hi guys, can any one who flies the Fokker 70 help me? When ever i fly this plane i always get one of the cockpit warning lights on which i think is labeled "FDP". I have tried turning various things on and off but dont seem to be able to get it to go out. Does any one know what it stands for and how to turn it off?
Thanks,
Jim

Jim,

Where is it on the panel? I've been flying the little Fokker quite a bit recently and I don't recall this one...

Is it perhaps LDP? I thought these are the spoilers.

If you push the lift dump button then it iluminate green.
and goes out after a while.

It has three settings I thought (or I am confused with the BRK):
- out
- blinking = after landing they will be deployed
- on = in-flight deployment

Jim,

I think you're referring to the middle one of the five buttons as it's the only one without a tooltip - from left to right in this row you have:

1. Stall warning STL
2. Overspeed warning - OVS
3. FDN button
4. Lift dumpers - LDP
5. Airbrakes - BRK

If it's the LDP button then your answer is in the posts above ;D

If it's the FDN button I'm not sure what this stands for but I've done some tests and it seems to light up when the aircraft is not in trim - if you set a high climb rate it will go on while the autopilot tries to get to the correct attitude to climb then go off when the aircraft is back in trim. Similarly if you set up a deliberate stall with low airspeed during a climb, as the speed bleeds off the light will come on.

I think it's a visual reminder to the pilots to check their Autopilot/Flight Director settings (is this what the FD stands for I wonder..?) when there is an out-of-trim or abnormal flight condition.

I've Googled it too but can't find a specific answer...

Hope that helps!

It might be a Alpha floor system that just warns you that you are nearing a the flight envelope.

But i can't find it on the real Fokker 70 cocpit

It is a warning light, and it is input is a special sensor in the mouse. FDP stands for Frightened Depressed Pilot ! :P

FDN: Flight Dynamic warning light. Will lit on when aircraft goes into stress-mode (i.e. steep turns )

Jim,

Do you click the button when it first comes on, to cancel it like the Master Warning/Caution? If so it stays on until you click it again - not sure why...
