procedure for "Flaps stuck/locked in up position"

[chrisporter41]

I was on approach and had just put in 1 degree of flaps in when my first officer told me that the flaps were stuck/locked in the up position. Oddly enough I could see that the flaps automatically continued to drop without any input from me with the flaps lever (i'm not sure this is realistic or not). Looking at the abnormal procedure checklists this is not addressed. I would appreciate some input.

Fly with the PMDG 737-800/900

Thanks,

In real life, flaps extend by degrees (5°, 10, 15° ... and so on) at intervals, according to your input on the flaps lever. The same happens in FS2004, unless you inadvertently pressed "F8" Key which fully extend the flaps or any button assigned in your controls for that purpose.

Sorry, forgot to mention I fly with fspassengers where "failures" happen from time to time and whatever aircraft you are flying the aircraft will behave or show the failure unlike default FS failures (another fspassenger example: right gear wont go down--the aircraft will show this from an outside view and the aircraft will actually behave as such. That was why I needed a procedure. Something happened that the stick shaker activated and with being so low to the ground I was unable to recover. Had I had instruction on how to handle the problem when I found I had no flaps I might have avoided the disaster.

Thanks,

I belive the proc would be to use a faster landing speed after ensuring the runway is long enough for the higher than normal speed.


According to the 737-300 AFM I have for Dispatch Class

"ALL FLAPS UP LANDING

Land at as low a gross weight as possible
Mantain Flap-up maneuvering speed until on final approach
Limit Bank angle to 15 deg below 210 knots
Approach and Land at Vref flaps 40 + 55 Knots"

Number may varry on a 800-900 series 737.

The a/a program you're using has no "alternate flap" system?

Simply would have to land at or above Minimum stall speed flaps up gear down. Would have to look a manual but probably around 180 to 190+knts. Vsr1. There are many Vspeed to reference this scenerio! Its not hard to do. The limiting factor will be runway length to get whoad stopped!

Thanks, helps a lot.

Hi Chris,

Approach speeds are based on 1.3Vso, or 130% of the stalling speed in the "landing configuration." If the landing configuration is flaps up, add 30% to the flaps ups stalling speed and fly that. If whatever airplane you're flying stalls at, say, 130 kts, move the decimal one place to the left (=13, 10%), multiply by three to get the 30% (39 kts), then add it to the stalling speed in that configuration (130 kts + 39 kts), for an approach speed of 169 kts. Your actual touchdown speed will be slower.

Thanks all.

If you've got 'Failures' set in the options, things can randomly fail (engine, controls, instruments etc), or the airflow can cause stress damage if you try to put the flaps or wheels down at too high speed.
