[2.9.7.59263 MT] Jet does not stop completely / chocks do not stop aircraft immediately

[Stickler]

In the attached track, note how I taxi into the last chance area and attempt to come to a complete stop.

It's only that the aircraft does not stop, but continues to drift forward even at idle power. If not installing wheel chocks, the aircraft will drift forward indefinitely.

Even having wheel chocks installed will only cause the aircraft to come to a complete stop after approximately 3 minutes.

The mission has 15 knots of tailwind in the last chance. However, the effect occurs also without any wind. The only difference seems to be that the stronger the wind is, the longer it takes for the aircraft to stop after installing chocks.

Using time acceleration during playback is strongly recommended to more easily see the problem. This would be merely an aesthetic one if it didn't

• prevent realignment/break the INS when attempting to realign in the last chance without chocks installed, or
• forces one to wait up to several minutes until the aircraft is REALLY stationary before starting the realignment, wasting valuable time.

Parking brake???

We have seen similar issues ourselves already as well. Its a weird one and probably has to do with fine tuning some friction values on the wheels - but that also influences how they behave during landing etc. It is all very finicky to get right.

While the F-4 as simulated by Heatblur does not have a parking brake and the Emergency Wheel Brake will not stop the drift, your input did cause me to do some more investigating.

I am pretty sure the problem has to do with the slope of the surface one is standing on.

The last chance in the track has such a slope. I tested this by reversing the parking position. Even with 30 knots of tailwind, wheel chocks applied, full military power and a gross weight above limit, the aircraft will very slowly roll downslope, in this case, backward. The funny thing is: In this scenario, setting the wheel chocks will actually ACCELERATE the backward drift.

The only way I have found to completely stop the drift is to hold the regular wheel brakes depressed.

If one does not want to do that, a workaround is to bind a toggle switch to the wheel brakes keyboard command or a custom joystick button.

The Emergency Brake isnt a brake. It reroutes hydraulic power to the brakes to enable you to use the wheel brakes even if the normal hydraulic feed failed.
