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. Under 14 CFR 91.167(a), no person may operate a civil aircraft in IFR conditions unless it carries enough fuel, considering weather reports and forecasts and weather conditions, to complete the flight to the first airport of intended landing.
