About Driftdown
What is a driftdown calculation?
Driftdown is used to determine the trajectory for descending altitude in case of an engine failure during climb or cruise. Flygprestanda's driftdown calculation compares drift down data with topographic data along your route to illustrate its decision points in case of an engine failure.
