Fuel planning.

ACS element text (the applicant demonstrates understanding of)

Fuel planning.

Bottom line

Misunderstanding or mishandling the aircraft's fuel system, a lack of adequate planning, trying to stretch aircraft fuel range, or an unwillingness to stop for fuel contributes to fuel-related accidents. Carrying enough fuel with a sufficient reserve reduces the likelihood of a low-fuel emergency or a forced landing. During the day, an airplane flown under VFR must have enough fuel to fly after the first point of intended landing for at least 30 minutes at normal cruising speed.
