How to induce Deep Stall
-
are you using the AFM?
Some of these deep stall instruction did work in F4AF. -
For tour information the current AFM is just just a bit more resistant to roll departure than the real .
This is due to a number I slightly changed in the FLCS a Loooong time ago and that I completely forgot to change back before release
This will be fixed in next BMS version (with a lot of other FM goodies )
But be reassured, this is very very subtitle difference
-
Will we finally be able to recreate this:
I tried it with 3 missiles on one wingtip and 0 on the other, and still couldnāt get a departure like that

Well this is not difficult as i already succeeded in doing it -as many others - secret is in speed and rollā¦.
-
Please tell me the secret, because I have tried many times at 30,000 feet, M0.9~0.95 and never got a departure.
-
That case in that video was one of the first things i tried after BMS came out. Works. M0.9 is too fast for 30kf, try it slower.
-
In the video he says it is over 35k that the test was done, rolled 90 right and aft stick, is that what you try in bms too?

@A.S:

Interestingā¦the test pilot said ātransonicā IIRCā¦is M0.9 not close to being transonic?

I tried it at altitudes varying from 25k to 37k. Rolled 90, aft stick. All I got was horrendous energy loss.

you know, its a very heavy switch to throw, the MPO. its spring held - you have to hold it in the override position. its a very strong springā¦
once again, you wont stall by holding 60 degreesā¦ the FLCS will limit your pitch authority and nose downā¦ and by this point you should have no rudder authority.
any time the nose drops, its generally the FLCS doing it for you, not the result of interrupted airflow over the wings.
Maybe it just works in the BMS flight model? But it works. Try it
Also, to answer the MPO question, the easiest answer can be found like so:
- Get into a deep stall (MPO off)
- Switch to external view and move your stick full forward and aft while watching the elevators.
- Now turn MPO on
- Switch to external view and move your stick full forward and aft while watching the elevators.
-
Iām gonna try this again. I was using a -D model before with just a center line tank and asymmetric missiles. I noticed the video has a -C model with a TGP as well.
-
As I said, thatās the only function of MPO: disconnect the neg G limiter.
-
Saw this and thought it was cool. No info on how the jet was loaded, but gives a HUD view of departure in left turn at M0.91 and 36~37k:
-
Nice find. I still have not seen a r/l vid with a comfirmed deep stall. They must as rare in r/l as they are in F4.
-
Found oneā¦ā¦ nasty
-
Does not sound like this guy was able to rock out of it with the MPO and has to use the drogue chute.
Some countries deep stall SOP is a chute recovery?

I think thatās the HUD cam from the video posted in post #22. You can just hear what sounds like the same female voice in the background of the AvWeb external video. And itās the same kind of test - Yaw Departure during Test Flight.

Chute did not deploy.
Check YouTube Description, then listen again ā¦. youāll hear it.

I heard thatā¦
then I think he said āchute ____ late.ā -

It was probably similar, but the on in #22 was a right-turn. This one was a left.
I tried to replicate and was still unsuccessful. Block 52 with center tank, TGP, two AIM120s on left wing, one (STA9) on the right. Tried M0.8 and M0.9 at 37k. No departure. I even added the āboot-full of right rudderā myself and all I got was the stall horn for a brief second. I donāt understand what Iām doing wrong.
-
Iāve tried a lot of load out. Even empty the forward tank to move the CG aft. No departure.
There is a TE that was bundled with BMS that I did get a good departure, but, never could repeat it.
It was a test flight TE. iirc ,āFLCS failureā maybe
