Hurricane Speed Test in game

'Full throttle height' is defined as that altitude above which the supercharger is unable to compensate for the reduced air density and both the BHP and airflow decrease in direct proportion to any further increased altitude.

Most of the flight data and engine data you guys argue about is converted to standard day conditions.

On non-standard day's FTH will change true altitude to maintain the same density altitude.
