ATC FL300 impossible (career mode)

[ModelCornet6746]

In career mode, on missions, usually medivac, ATC is requesting I fly to FL300 in a cessna which has a maximum ceilling of 17,000ft.

If I ask ATC to decrease altitude, it allows this, then auto defaults back to FL300 again repeatedly instructing me to climb.

Any ideas?.

Before starting ANY mission, Open the EFB and change the Flight Level on the rought screen, then scroll tot he bottom and click “File with ATC”. Flight level is in hundereds of Feet 1FL = 100 feet. FL100 = 10,000FT
