Max Altitude and Max Speed

[n-wuttiphan]

Hi BlueSky team,

I would like to ask if It is possible to change the maximum altitude and speed of an aircraft (ex. the default B738). I noticed they are capped at around FL370 and their max speed is tied to the altitude which will be in the range of 2xx-3xx knots (in TAS). Would it be possible to raise it to FL390-FL450 with a max speed in the range of 4xx~5xx knots? Is this where it can be adjusted?

Kind regards,
Nitipads

Hi @n-wuttiphan,

It looks like you've already found where to edit those: in the OpenAP performance xml files.

Hi!
Have you managed to get any airplane to, for example, FL400? Because, for some reason, I cannot get mine to more than FL260-FL370, approx, even when their limits are more than that, as you have shown
