Drift Down

Drift down is the gradual descent an aircraft makes after losing an engine at high altitude, descending to the single-engine service ceiling while maintaining safe terrain clearance.

In private aviation, Drift Down isn't academic — it translates to real operational or financial implications for your flight. Understanding it helps you participate in the planning process rather than delegating every decision to your broker.

Charter pricing reflects operational complexity, and Drift Down is one factor that contributes to that complexity. Depending on how Drift Down applies to your specific itinerary, it could influence the quoted rate, required crew configuration, or aircraft selection.

The core concept behind Drift Down is recognized internationally, but implementation varies. The FAA, EASA, and national aviation authorities each apply their own regulations, which means Drift Down may carry different specific requirements depending on where you're operating.
