Engine spool-down time vs. real aircraft.

Since I bought the Harrier, I noticed that when chopping the power (after a vertical landing) the spool down time seems much longer than according to the many RL videos (also, there is a very distinctive whine that is completely lacking in DCS).

Reading the manual, I found this interesting bit:

2.3.1.3 Engine Fast Deceleration Solenoid

To avoid aircraft bounce on vertical landing, DECS incorporates a fast deceleration solenoid that is armed for 1 second by the weight on wheels (WOW) switch. A rapid throttle chop will activate the fast deceleration system and immediately reduce fuel flow. For aircraft with IPPC-227 incorporated, the engine fast deceleration solenoid is disabled.

So I suspect this is not included/simulated by Razbam.

I looked for what IPPC-227 is but couldn't find it, maybe Razbam can shed some light on this and confirm if / when this feature will be implemented?

Thanks,

IPPC-227 FDS = Interim Power Plant Change - 227 Fast Deceleration Solenoid.

I'm finding documents mentioning it as far back as 2006. I'm assuming given how long it's been since 2006 and the fact that your flight manual excerpt even mentions it that it's been implemented in the real jet.

Nice Find!

Either way, every harrier seems to have this feature, so the question is: when will we see it in DCS?

I'm surprised this isn't getting more attention.

It's quite a basic part of how the Harrier engine works and has a great effect on the realism of vertical landings. In fact, what I have to do now is to wait a few seconds with nozzles fully forward and brakes set until the engine spools down enough, to avoid moving forward when I touch down.

In real life, the engine spools down very quickly and the pilot can rotate the nozzles back as soon as he is safely on the ground.

Agree, And that cool whine sound it makes going to idle. :)

There are still lots of basic * features that are still not added. I hope this one gets addressed.

Up ! Please take a look at this Razbam .;)

Bump

Paging @=Decoy=...can you please check on this

I bet they are like "shit, no idea the Harrier had such a feature, let alone how to implement it...better pretend we didn't see this":P

In light of yet another request for this feature (https://forums.eagle.ru/showthread.php?t=245815), BUMP!
