For sure Raynen!
It wasn’t stable and I was surprised it was able to increase airspeed at all.
Probably only because I hit 31k and nosed down to gain some speed.
Get it below these speeds and it does not gain airspeed, only bleeds off until stall.
It may be performing slightly too well when at alt & below .8
I doubt it’s controller related and more that your too slow by the time you get to 30k. How are you getting there and what speed are doing.
Try this.
Use preset weather, clear skies. Full fuel.
Take off from a sea-level or close to it, airport.
Go full AB, and engage fpas for 5deg climb.
Don’t turn, just a straight depart shallow climb. Hands off to 30k.
What is your speed at 10k, 20k and 30k?
Level off at 30kish, engage balt and stop AB, but put throttles to full.
What’s your speed in mach.
I’ll do the same thing when I get home in an hour or so to compare.
I noticed the same thing, FleeToTheCleve. Used to be pretty easy to stay above mach 1.0 (I could usually stay at mach 1.25 or so) without burners in cruise at FL300, but now it will decelerate to mach .098 or so without the burners every time.
I flew a flight about a month ago from KMCF to KNBG, and was able to fly at about Mach 1.3 or so the entire time I was over water without the burners on. Did the reverse last night, and couldn’t get it to stay above Mach 1.0 without burners on. Also seems like it has less power/thrust throughout the flight envelope in general.
Maybe it’s more realistic (I don’t really think so…) - but it’s a lot less fun!
The F-18 cannot super cruise above Mach 1. If it was doing it before SU9, then it was bugged before and is now fixed
Going to try to find time to dig deeper to find the envelope where the performance drops off, above M0.85 everything works as expected with MIL power up to service ceiling, but it should be able to accelerate from as low as M0.4 at altitude with MIL power. I normally had no reason to fly below .85 at altitude so never noticed this issue prior.
@FleeToTheCleve
Here goes, you should get numbers close to these.
Sealevel to 30K. (phko)
Gear up at 175kts, AB engaged, flaps to auto.
5deg on ladder, fpas engaged.
Hands off, but slight adjust to maintain 5deg after passing mach boundry.
10,000’ = 647kts
20,000’ = m1.31
30,000’ = m1.35
balt engaged about 29,900, AB off, throttles to full mil power.
Settled in level at 30,300’, speed bleeding off slowly.
Speed continued to slow until m0.97
M0.97 held until I throttled back.
As long as your at least m0.45, it will remain in level flight & will gain airspeed from that point up.
It will be a very slow increase for sure, but AB will help. As you get nearer to m0.8ish, airspeed will increase quicker and then hold up at m0.97 in full mil power.(AB off)
Full AB was m1.41
*I tried in decreasing steps of 0.05 from m0.8 to m0.45, then going full mil to check.
At 0.44 it was not able to increase airspeed in level flight.
At 0.43 it was unable to maintain level flight, becoming worse as the flight computer increased AoA,
as expected, resulting is a stall. (Recovered at around 18,000’ , fun stuff 
)
Honestly feels about right over all, low alt performance is much better.
But it will not hold super cruise, drops to m0.97 always.
Uncertain on super cruise speed. Will it maintain m1 or close 1.05ish @mdapol
( Prior to SU9, m1.1 or 1.2 maybe even, which didn’t seem right either. )
I was going to go through the data, but called back into work for another shift today…oh joy 
but I’m sure @Raynen is doing this as we type 
Tomorrow tackle the external light controls…
It’s something to do with how the dimmer gets set using the FALSE flag in the apron.flt file. If you change the FALSE flag to 0 for the associated lights everything works normally. Clearly not a viable fix for xbox users though.
I am having the same issue and I use a gamepad to fly around
Did you also not read the patch notes?
Not done all the testing I wanted, but initial tests show some conflicting results. MIL power acceleration tests are just bad, it improves above M0.85 until you start building shockwave drag around M0.94. Now doing some of these tests at SL and using the Debug menu I see the engines are putting out the correct thrust for MIL power, so this points to a drag related issue being at least part of the performance problems.
Edit: had a “moment” part of the trend I was seeing makes sense
Going to have to do some testing over a larger range, but initial debug tests show going from Sea Level to 6000’MSL there’s a already 14% drop in thrust generated for the same KIAS due to the lower pressure, by 20,000’ MSL this drop has reached 44%.
At Sea Level below 360 KIAS the amount of excess thrust available at MIL power is pretty good, as soon as you increase speed and/or altitude the available excess thrust starts to fall off faster than it should. My best guess is there’s 2 potential issues going on, the jet generates too much drag once above 360 KIAS, and the MIL power thrust loss with altitude is potentially too high.
That being said the afterburner thrust performance above FL300 is actually really good up until it hits a wall at M1.48.
Do you have real world performance data that you are comparing the sim too?
