missing info Afterburners Fail to Ignite

[Bucic]

BTW, it's the same with pushbuttons. The issue is not "latching". I don't remember whether it takes just one cycle or more though. In any case we've got just the lengthy tracks for the devs. Maybe this week I'll fire up DCS to capture the shortest possible stint.

Still present in current build. 

Best way I find to trigger it is to creep up to MIL power slowly, engines will hit 103% but you can push more to bring the EGT to the first red line (680c) 

Once you are max EGT and max RPM pushing into AB which you are already into on control indicator will fail to light AB.

Also

Check this video, pretty sure this is A model so whatever engine that was...

But, check the fuel flow and egt gauges, they behave nothing like what we see in dcs. Not even close.

Can see the engine gauge pack is a little different in image, but response to throttle and egt should be close right?

Our F-5E is a bit weird. I found the only reliable way to get burner light-off is to pull off *enough* power that the RPM decreases slightly below MIL, then push the throttles up again.

If you pull it out of burner, but not enough to drop RPM, pushing the throttles up doesn't cause burner light-off.

When this behavior occurs, there is a strange bump in fuel flow, but not remotely close to what it should be for max AB.

This module could be the best if these issues would be resolved. These issues have existed since release.

I'm very pleased they addressed the drag issue that plagued this module for so long, but there are still some "rough edges" that need to be sorted out. Slats still produce too much drag, and max clean speed in level flight is still too low (though it is greatly improved). I struggle to break Mach 1.0 at sea level, clean.

There is a wider problem with too much drag with all modules when carrying stores, but at least everything is affected by that. Even the F-16 has noticable degradation in performance carrying two wing-tip AIM-9s.

As is "finding" MIL power.

I find myself looking at RPM and seeing 102% and thinking I'm at MIL only to slide the power up more and see the TGT increase without RPM increase.

very puzzling but as we know more heat = more thrust

I do wonder if this isn’t a real system recreation. An all electromechanical Reheat can be a bit temperamental. Haven’t looked at the (whatever the Air-force calls the NAVAIR) in a while. There may be an actual linkage or electromechanical lock out around the detent to prevent undesirable…..excursions we’ll say. 
 

Never flown one so Dono.

Hey all, just reviewing this section, and realize this has been around for a while but is this still something people are experiencing, if anyone still sees it and wants to include an updated track and explanation I can review it. Thanks!

seems to have been fixed for me

They are too eager to ignite now

It's pretty much impossible for me to tap "slow afterburner increase" to go from 90% to even 95%. The pointer stays at 90% and after several very short taps the AB kicks in.

[Bucic]

They still fail to ignite sometimes. Log and track file https://1drv.ms/f/c/66cf2646234394fc/ErPDfopS8NxGvDMUlCKDSi4B1czHPRfbp3TVD-BSkJsDOg?e=sTqRgb

This bug report is not for the today's release. My DCS version is 2.9.12.5336 so pre-update.

Keyboard only, page up/down only. AB failed to ignite when cycling the throttles at least two times i.e. at least two fails are included in the track file.
