Stage 1 of Take-Off Segments covers which range?

• A. 35 ft to Gear Retracted
• B. Gear Retracted to 400 ft
• C. Acceleration Altitude 400 ft until Flaps Retracted
• D. Flaps Retracted until 1500 ft

Answer: (A)

Take-off segments group the climb into phases based on configuration changes and fixed altitude or height markers. In Stage 1, the airplane is in the initial climb from liftoff up to the point the landing gear is retracted. This captures the period when the aircraft has just left the ground and is still with the gear down and flaps set for takeoff. The moment the gear retracts marks the end of Stage 1 and the start of the next phase, where other changes (like gear up, flap retraction, and acceleration targets) begin. The other ranges describe later portions of the takeoff after the gear is up or after additional configuration changes, which is why Stage 1 is specifically the interval from 35 ft above the runway to gear retraction.
