Just out of curiosity, Ray.....have you ever tried a transatlantic flight with no passengers on board? I would be curious to know the difference in performance (fuel burn/altitude reached etc).

That's one thing I've never tried Chris but I believe it's one of the few situations where FL600 across the pond could be achieved.

I've just landed at Honolulu. Flight time from throttles forward to wheels down was 2h 27m.

Decel point was 63nm before SHARK.

12T of fuel remaining. CPS-X calculated 11.8T. 👍

The maximum altitude reached with ISA of -5 throughtout supersonic flight was FL581.

Landing rate was 166fpm which is very nice at 171kts - a tad fast.

And 801Mb of VAS remaining. Some of you younger ones might need to ask what that is! 🤣 Not applicable to MSFS of course.

VAS…there’s a three letter acronym my brain has blocked from my memory! 😂

I remember the chimes of death in 32-bit P3D and FSX…put all sliders left and try to land quick before the sim crashes!

I’m watching a YT video and the Elapsed Time and Chrono readouts are showing zero. Are those timers enabled?

On real Concorde videos you’ll hear the Captain ask if everyone’s ready and after confirmation you’ll hear him call 3 2 1 NOW.

3 was the point the Elapsed Time button was pressed, 1 was when the countdown Chrono was started and NOW is when the throttles were slammed forward.

The Chrono time was monitored by the FE and you’ll hear him call out the final few seconds after which he’ll enunciate “Noise” at which point he would cancel the reheats and retard the throttles to a predetermined level. Generally 93% N2.

The Chrono time is variable of course depending on weight. So those timers were crucial to proper operation. Are people using them assuming they’re enabled?

I’ll have to check I think it wasn’t working upon release but it was operational after an update. I usually don’t use an in-game timer but rather the one on my yoke so I hadn’t really noticed. I don’t think it has full functionality through.

@JasonPC, understood, thanks. There would have to be a way of entering the time in the Chrono timer of course.

In the P3D Concorde it will automatically cancel reheats and retard the throttles to the predetermined level on reaching zero. Very handy when you’re busy flying the aircraft.

Yeah as I remember in the Concorde-x you could set your reheat chrono to count down and manage another timer for the elapsed time. Fairly sure the chrono only functions as an elapsed timer. Granted there are fewer things to manage here and I think the sim is a little more forgiving if you make a mistake compared to the Concorde-x. I know I always felt quite overwhelmed with the FSLabs one.

My question wasn’t meant as any criticism. The developers have clearly stated it’s not a fully featured version. I was just curious if those timer options worked.

It took me quite a while before I took control of fuel management in the FSL one. It seems daunting at first but you do get used to it after time and the procedures aren’t that difficult. Just practice. 😉 And it gives you something to do when in Max Cruise mode.

Ok, my next stupid question: as soon as you use AT, the sim turns afterburners on no matter what position the reheat switch has. BUT: if I control throttle manually, afterburners never kick in, even if the reheat switches are in the up position... Do I have to bind a button to afterburner on?

@AnkH, the real-world procedure prior to transonic climb at FL280 was:-

1) set 60000 in the Altitude Selector

2) Engage Pitch Hold

3)  disengage autothrottles

4) throttles full forward

5) Inner reheats on

6) outer reheats on

7) start the timer.

Use the pitch adjuster on the centre console on the pilot’s side to keep IAS just below Vmo.

Once through Mach 1 engage Max Climb. Reheats stay on until Mach 1.7 reached around 43,500ft. Make a note of the timer when you disengage reheats. They should be on for no longer than 9 minutes.

Thereafter reheats were not used. If you keep autothrottles off the reheats should stay off. Watch the fuel gauges. They’ll increase significantly if reheats are on. 13T per engine.

Personally, I’d try to fly with autothrottles off as much as possible to avoid reheats being erroneously engaged by MSFS. But irrespective of the throttle position if you select reheats they should engage.

There’s some limitations apparently in the msfs coding where AT causes the afterburners to turn on (at least the animation not sure if fuel flow is showing that reheats are actually being used). AT is supposed to be turned off prior to performing the transonic climb but I’m not quite sure if max cruise or max climb work properly with AT not set to armed. 

OK I figured out what's the problem (or one of the problems). It involves using the throttle quadrant. Physical throttles at 100% end up turning the reheats on. I think by default (by dragging the throttles in the virtual cockpit) the maximum setting with reheats off is around 98%. So I will have to do some creative programming of my throttles in Spad.next to prevent this from happening.

Or land on a runway with just a black line on each side and no detail whatsoever.

So I did some editing of the maximum values of my throttles so that it ends at 89% thrust for maximum throttle. This ends up not triggering the afterburner. I have a button mapped to each reheat switch and when I hit those, it bumps the throttle to 100% and turns on the burner. I had to make another trigger to set the throttle back to 89% when reheats are turned off, but only if the throttles are set to maximum. Seems to work well but a lot of work involved. Don’t know what could be done to fix the auto throttle from using reheats. Maybe if there’s a way to set the logic to only use 89% thrust?

I  mapped the 4 afterburners levers to 4 buttons of my CH Throttle Quadrant, using the "toggle afterburners # .." option, but they doesnt work.

I tried also with the general "toggle afterburner" to a sole button and also a lever, but no way again.

Is there any way to fix that ?

Thanks

It’s using custom LVARs for the after burners so you’ll need a program that can address those.

I sent a bug report in for this issue, and the answer I got was they are aware of it, but it's a current limitation in MSFS as far as the DC devs see it.
