PC light turns off at altitude above 59000feet

[lucky-hendrix]

Not sure if it is a bug or a feature but the PC light turns off at very high altitudes(>59000 feets), even tough the afterburner is still engaged (same visual effect and same fuel comsuption).

Also at that altitude Tt7 is very low (about 410°C), again,. not sure if normal or a bug

I don't know, but you're above operational ceiling...

PC light off and AB on can happen sometimes, it is a known bug, Zeus said.

Then maybe there is another bug, I will try to reproduce, but I think in remembered being able to maintain level flight at that altitude

What I meant is that the plane is probably capable to go that high.

 

But operational ceiling is 50 000ft or 55 000ft because of cockpit pressurization.

 

If target is flying higher use missiles.

Are you sure the engine is not simply stopped ? I have seen that at very high altitude, the engine stalls (which seem pretty logical) and you have to go lower and restart it.

No it wasn't, rpm still 100%

Isn't usually the service ceiling defined as the Max height at which the plane can maintain level flight ? I have difficulty seeing why the pressurisation system would have problems at that altitude

Every plane has pressurization ceiling, because the fuselage needs to sustain the difference of pression with outside.

 

In planes like SR-71 or U-2 pilots wear space suit, it's lighter than building the plane strong enough to sustain pressure needed at 70 000ft.

 

Mirage III could zoom climb to 70 000ft with special suit too.
