FAA Flight Instructor Airplane (FIA)Flight Maneuvers and EndorsementsEasy
During slow flight on a private pilot practical test, the ACS requires the applicant to maintain altitude within how many feet of the assigned altitude?
- A150 feet
- B100 feet
- C50 feet
- D200 feet
Show answer & explanationAnswer & explanation
Correct answer: B. 100 feet
The Private Pilot ACS standard for slow flight requires the applicant to maintain the specified altitude within 100 feet, heading within 10 degrees, and airspeed +10/-0 knots while flying at minimum controllable airspeed.
Why the other options are wrong
- A. 150 feet is not the recognized ACS tolerance.
- C. 50 feet is tighter than the published ACS tolerance.
- D. 200 feet is too loose for the ACS slow flight standard.
Slow Flight ACS Standards
A maneuver requiring the pilot to fly at minimum controllable airspeed while maintaining precise control of altitude, heading, and airspeed.
- Altitude tolerance: ±100 feet
- Heading tolerance: ±10 degrees
- Airspeed tolerance: +10/-0 knots
Memory trick: '100 up or down' keeps slow flight in bounds.
