Question to the speed brake

[Atari800XL]

Hi everyone,

Is it in the real F-15E so, that I have no lights or other feedback in the pilots frontseat when the speed brake is extracted?
It's really cool to see the speedbrake "hesitate" when I use it at higher speeds, in the F-15C (FC3) the speedbrake will extract and work at nearly every speed.

And even when I raise the seat-position, I can't see the extracted brake in the upper mirror. Are the only ways to recognize a extracted speedbrake the braking speed in the HUD and the sound? (and external views?)

Sorry for probably the stupidest question of the week but this interests me. I love the planespotter-videos of landing F-15's, touching down, keeping nose up and then extracting the speed brake. I often try to land exactly this way.

Thanks and best regards!

That's correct, no light or gauge indications, etc.

Thank you, I inspected every corner of the cockpit with fixed TrackIR and maximum zoom ... and found nothing

So strange …

how to tell if airbrake is deployed?

turn your head?

No light in the real jet.  It’s a huge “barn door”.  You can hear it, feel it, and see it.

Yep, just look over your shoulder. It's not like the viper where a partially deployed brake can't be seen.

My troubles have been when the brake is extended just a bit. Enough to cause drag but not enough to see it from pit.

also... YOUR THUMB is currently holding it open! 

so, kinesthetic feedback would probably be a good indication that the speedbrake is employed

Sb does not require SB to be held open manually.  Switch has static switch positions to freeze speedbrake in place.

There is an option in the control setup for fully extend or retract.

i'm curious --- is that how the SB functions in real world??

Yes.  The switch holds in a constant state

In the DCS F-15E, there are separate controls for the speed brake that you can choose from depending on your controls and the type of switch you want to bind it to: momentary (what I use on my Virpil CMP3 throttle for example), or a 3-position switch that holds in place and you have to put back to centre yourself (such as the TM Warthog throttle).

As thought, I just timed it.  It takes roughly 3-4 seconds to deploy and 7-8 to retract.  Me, I'll just count whilst pressing the button.

Its roughly 2 and 5...so you must be counting a bit fast

Wouldn't deny that.  After all, I was in a jet fighter...
