SECTION 4
Departure Procedures
Engine Failure Immediate Action and Off-Airport Landings
While a complete loss of engine power is a rare occurrence, it can happen.
ATP pilots must know the emergency procedures from the POH and have a
contingency plan in mind for the worst-case scenario.
General Guidelines:
• Know immediate action items
• Best glide speed & altitude = time
• Gliding distance from 1000 ft. AGL = Approx. 1.5 miles and 1 ½
minutes
The following chart comes from extracted POH data and shows the
glide distance and time expected after an engine failure with no wind
and at max gross weight. Aircraft performance may vary considerably
based on wind conditions, airplane weight and bank angle.
