reverse toe brakes axis?

Got it. It was the Anti-skid brakes stuck on full. Funny that releasing them didn’t seem to work before.
I’m sorry but I don’t understand what you are saying : « anti skid brakes stuck to full » has no meaning
The only reason for which your brakes are on is that( without knowing ) you have bad analog axis setup for brakes in your config
OR
You have a bad joystick control setup and the Parking brake command is constantly pressed
Yes, Brakes are either ON/ANTI-SKID/OFF. Only ON will stop you…

It’s happening again. It is a random thing where my tires get stuck and I can’t move on the tarmac without full afterburner. I am unable to re-create the problem. I tried taxiing around for 30 minutes last night without any trouble. Sometimes it occurs on landing, other times on taxiing or takeoff. My wheel brakes are mapped to the keyboard; not an axis. It’s a sudden occurrence and nothing I do will release the wheels, except restarting the mission. The cockpit switches for braking are unchanged when it happens. I’ll be rolling along and the F-16 just stops dead without any input on my part. Anyway, I seem to be the only person with this problem, so it must be peculiar to my system devices. If I discover anything more I will post. Thank you.

@Dufus Happened to me yesterday at Daegu. Practiced the ILS Weather mission a couple of times. When it happened, I had just landed on 31L and turned right off the runway onto txway D. Having landed at 31L I wanted to see what parking directions I would get if I turned off in the “wrong direction”.
I was given parking directions for Delta-Foxtrot-04, which meant I was supposed to do a U-turn. Not sure if that is by design ?
I Alt-Tab’ed out to bring up the parking chart, when I got back in BMS my jet was stuck like you describe. No chocks, no parking brake but it takes afterburner to get it to move.
Curious which airport it happened at for you. Were you in comms with ground control at the time and did you Alt-Tab out at any time ?
-
you just broke your gear after overheating your brakes
-
In my case, not sure? The landing wasn’t especially hairy and no excessive braking took place as I recall.

@jayb - I would look for a key collision with some other assignment and the “k” - Brakes - key. Could be that’s getting stuck/invoked due to some other assignment or combination of assignments.
I had one once that caused my Hook to cycle when I put Brakes on and closed the Speedbrakes during landing rollout. Key collisions can be hard to sort, but that’s what I’d look for.

@Stevie Yeah good point. It doesn’t happen often but I will doublecheck my bindings

Hi,
something like described here happened two times in MP to me(us) over the last few days.
In both cases we made a hotpit refuel.
First occasion:
- Land at airbase for hotput refuel
- After refuel the jet had a strong drift to the left and i had to use way more power to move the jet than normal
- Decided to T/O anyway, after NWS off, drift to left was uncontrollable
Second Occasion
- Land at airbase for hotput refuel
- T/O normal
- Return to homeplate, after touchdown jet drift to left, needed more power to taxi
In both cases we had good landings, Also checked “brakes-chart” to be sure no overheat problem.
Tried to repro in SP, no luck.cheers

@Magic49th - what you describe is a classic case of a blown tire. And the fact that it happened after landing to refuel is almost a guarantee that this is the case. When landing with heavy loads (I’m assuming you still have weapons remaining otherwise why refuel and takeoff again) or even if you simply try to stop too quickly, you can overheat the brakes and cause a tire to fail. It doesn’t have to happen immediately either…you can be sitting still on the ramp taking on fuel and suddenly the aircraft will lean to one side, that’s you tire failing.

Even IRL, when the tires overheat the rims where they are mounted, they have a thermal indicator. When the brake block reaches high temperature, it melts and lets the air (nitrogen) that is inside the tire escape at full pressure, this is done to prevent the tire from detonating and fragments of it and the brake block flying out and injuring or killing ground personnel.
Even if I remember correctly, in the actual flight manual of the F-16 block 5,10,15 it mentions that when hot brakes are suspected, the aircraft must go to the hydrazine bay and remain there without the pilot leaving the cockpit, even the Ground personnel have the obligation to approach from the front or behind the aircraft as well as firefighters or aircraft technicians.
What is happening here in this thread is the same situation and very well implemented that is in our FALCON BMS. On more than one occasion, as @Zeus say, I landed with weapons (candy) and while I was on the ramp, refuling, I saw how the aircraft tilted and I already know that it has a tire that deflated itself.
Soviet aircraft do not have tubeless tires. So when the brakes overheat they flatten and have no protection system. They blout out.

sometimes the K stays stucked, just press it again when it happens

Magicbrakes overheat

Ok guys, thx for the info directing to brakes overheat.
But then the published chart for accumulative brakes energy is wrong.
I checked our grossweight, wind and airspeed when brakes were apllied, according to the mentioned chart we are in the green area.
So why brakes overheat when in green area?https://www.falcon-bms.com/articles/flight-model/changing-the-brakes-model/
cheers

@Magic49th I live at the bottom of a steep descent and whenever there is a driver, that doesn’t know the road well passes by there is always that smell of burnt brakes and clutch behind the car.
The theory is not the same as RL. I understand BMS is not RL but the code as I see it is not 100% by the books either. Maybe there are other aspects on brake malfunction in BMS. -
Not 100% sure, but it now appears that the cause is my old CH Products Fighterstick. The trigger seems to stick on, which I have mapped to both 1st detent and wheelbrake (depending on the state). The other night, in a dogfight, my gun stuck on and emptied before I could press it again. It is very rare, which is why I could not re-create it, and I only rarely use the cannon. Thanks for all the suggestions. I will post again if new information comes to light.
