@aeaeaeaeae ok now im a stupid guy and now idk how

can anyone tell me how to input command expression ?

@edensk I did it dare too late.. I uploaded the aircraft..

@Whatseatoya that's strange considering you typed it correctly.
Unless you did it in the designer, of course...

@edensk bro it said "command "DebugExpression" not found" :/

@edensk thank you very much for helping!!!! :)

(GS > 0.1)*(round(-AngleOfAttack) > 7)*(AltitudeAgl > 1.91)
for stall
gtg now

@edensk ok

If you published it unlisted and tagged me there it would be nice

@edensk Thanks. Do i have to send you the plane??

Of course

@edensk Yes! As long as you're okay

no risks

oh, strange. I can do it for you if you want to though

@edensk ummm... the command keyboard doesn't open..

@edensk are there risks of doing it?

You have to use the dev console.
You activate it like this and open it by pressing with three fingers.
Once it's open you can run the command DebugExpression round(-AngleOfAttack*100)/100 to see your AoA. (this specific code is to show up to two decimal places)
You can just do DebugExpresion -AngleOfAttack if you want to se the entire number.
For altitude above terrain use DebugExpression AltitudeAgl, for example

@edensk Thanks but I don't know how to measure AoA...

Stall warning:

(GS > 0.1)*(-AngleOfAttack > a)*(AltitudeAgl > b)
a is the AoA at which the stall occurs
b is the altitude in meters above terrain at which the aircraft no longer touches the ground (you can try with 2)

Altitude warning:

(AltitudeAgl > a)*(AltitudeAgl < b)*(rate(AltitudeAgl) > 1)
a is the altitude above terrain in meters at which the aircraft no longer touches the ground (you can try with 2)
b is the altitude above terrain in meters below which the warning will work
1 is the climbrate in m/s above which the warning won't work (to make it not work during take-off)

@edensk Ummm... then do you know how to make stall warning or low altitude warning beacon lights?

You can't
