inner flaps "stuck" after landing

[LOW_Hitman]

Hi all,

after i landed on the carrier the inner flaps stuck - i put the leaver forward but only the long, outside flaps are retracting. I watched the speeds carefully so iam pretty sure i not "overspeeded" them.

And because of this iam not able to use the wing sweep.

What iam doing wrong?

Thnx for your help!!

Were they ever retracted after take-off? It is pretty easy to overspeed them when taking off with AB.

I never experienced them stuck, except when I oversped them.

[LOW_Hitman]

yes they where fully retraced after the takeoff - i also got no master caution warning. I retract them at the moment the plane left the deck.

After the plane left the deck i pushed gear up and flaps up, also put the throttle back.

The strange thing is, after the landing - hook up and flaps up - only the inner flaps stuck fully down. No warning - no master caution... strange

You may have lowered them at too high an airspeed.

Also, I don't recall any warning lights when flaps get stuck down.

You are talking about - during the landing ? So maybe i lowered them to full at to much speed? ok - ill give it a try and but iam sure i didn't lowered them to full above 250 knots.  thnx for that hint!

Do not lower flaps above 225 KIAS. 250 might already have been too fast.

Thnx! ill check it the next time to not lower them to much until final approach! Thnx guys for you help!!

You need to lower them on the downwind leg so you can get on speed. Just be below 225 as Jayhawk wrote above.

ok - well thanks for your comments! Now iam sure it was because of overspeed - during landing i lowered the flaps 1 step at 250 knots and full above 200 knots.

I think the actual overspeed number is around 225 for flaps though I always make sure I am atound 200 as well for flaps just to have a margin of error

They will extend fully when the FLAP handle is at more than 5° extension. Also beside speed there is also 2.5G limit afair so be gentle.

How are you dealing with this speed during takeoff? With full afterburner the plane is hitting more than 200 knots to fast to react.

In the B, no AB on take off, and in the A, you can reduce it a bit just after take off, and even if not, you should have ample time to retract the flaps. Just something you need to prepare yourself ahead for.

Wouldn't the OP be refering to another issue - regarding DLC use when landing, which :

- if the DLC is not tweaked correclty after landing, can indeed cause the inner flaps to not retract completely and get stuck at 28 % position ?

 

Because I've noticed it only happens to me after landing since I'm using the DLC.

DLC wheel also controls maneuvering flaps depending on the mode so if you use it as an axis you have to make sure it goes back to center if you don't need any other position atm

Didn't know that and, pretty sure I never used that mode yet.

Man... I loved the F-14 exactly since the first time I knew it, but is it a complex bird or what...

In the A, full AB takeoff, the moment I pitch up and I'm leaving the ground, it's flaps up, gear up (in that order, wheels can be out up to about 300 if they have to). You wait 5 more seconds, and ya, flaps stuck, no wing sweep...  It's definitely quick, but it's not faster than you can react.

Just pull the power back once airborne to slow your acceleration.
