This was weird. Never happened before today. I landed, selected thrust reversers, and the plane immediately, literally popped a wheelie and stopped from around 110kts in probably about 50 feet.

I'd think it was some stupidity about the world-tearing that's causing us to crash while on the ground, but I loaded at a different airport, hit the reversers while stopped and holding the toe brakes, and it popped another wheelie and started spinning around the main gear while bouncing backwards several hundred feet. 

It did not display this behavior when I was flying it around shortly after the AAU1 update. I'm using the default Asobo livery, so its not a 3rd party issue. Anyone else ever get this behavior?

I'll have to give it a try. Have to admit to not flying the Longitude much after the last update as I find pitch is virtually uncontrollable and pitch movement of the aircraft is really funky.

I'm really curious about the thrust reverser function - actually sounds funny from what you describe.

If you are struggling with operating the Longitude after AAU1, I suggest you head over to WT's Longitude discussion channel.

So far my experience landing the Longitude has been pretty rock solid - at least it was on 19th Feb at SEQM RWY 18.

Agree it can be a bit twitchy sometimes (esp in cross winds etc) but it would seem from what you described, that this may not be a universal bug with the plane in itself.

Since the release of AAU1 I've done at least 25-30 flights with the Longitude - and I never experienced any of the issues being reported here - "wheelies" or "uncontrollable pitch"

You probably had accidentally set the parking brakes during the flight

This. Check key binds, sounds like a double bind reversers + parking brake.

I use thrust reversers on every of the 10+ landings I've made on the Longitude and no problems.

Nope. Parking brake is fine. It's not even bound to a key on this airplane, I just click it in the cockpit. Did some more testing today. It's a thrust issue. From a standstill, throwing it into reverse accelerates the plane *much* faster than full forward thrust. It's like it has afterburners.  Yes, this is full reverse thrust, since I'm using a button to engage it because the Bravo doesn't have a reverse axis, but even at full reverse thrust the thing should not be outrunning Formula-1 cars while going backwards.

I had the same issue and solved it (not in the Longitude as yet, but in other aircraft), setting the same button on my Throttle control to kill the engines and toggle the reversers at the same time

How did you do that? Which button if I may ask?

From memory (away from my PC now), we're talking about two sim actions, both mapped to the same joystick button (of your choice, depending on your hardware: mine is the Thrustmaster TWCS Throttle and the button is the orange one to its right side):

1. Engine shutdown (or so; look for something that would do the same).

2. Toggle Reverse (or so)

So, this way, you're making sure your engines are at idle when you apply your reversers, like you are accelerating.

Thanks alot!

I dunno. I started while stopped, with the engines at idle. They spooled up in reverse, of course, but the backwards acceleration was much faster than the plane accelerates going forward even with the throttle set to max. It's behaving as though reverse thrust turns the engines backwards, then adds 4 more.

What button are you exactly using for reverse? I use "reduce throttle" (default F1) and it works as expected.

Honeycomb Bravo buttons 26 and 27, which are set in SPAD.neXt to "Send THROTTLE1_DECR Event" and  "Send THROTTLE2_DECR Event" respectively when held.  There are no assignments for the Bravo in MSFS.

I should probably note that this command works fine in other aircraft that have reverse/beta range for when I want to use the prop handles (which more closely match most bizjet throttles) rather than the airliner handles.

Should probably also point out the meat of the issue, which is that this airplane should not be physically capable of accelerating like that in reverse regardless of what control inputs it thinks it's being given. So, if I can find a workaround control scheme that prevents this from happening, great, but that it's possible for this to happen at all indicates a bug in the reversers for this specific airplane.
