4.1.3.1. MinimumAcceleration Height
JAR 25.111 Subpart BFAR 25.111 Subpart B
“JAR/FAR 25.111
(c)(2) The aeroplanemust reach V2 before it is 35 ft above the takeoffsurface and must continue at a speed not less than V2 until it is 400 ft above the takeoff surface”
4.1.3.2. MaximumAcceleration Height
The Maximum Takeoff Thrust(TOGA) is certified for use for a maximum of 10
minutes, in case of anengine failure at takeoff, and for a maximum of 5 minutes with
all engines operating.The Maximum ContinuousThrust (MCT), which is not time-limited, can only be selected once the enrouteconfiguration is achieved (i.e. when the aircraft is in clean configuration at green dotspeed). As a result, the enroute configuration (end of the third segment) must be achieved within a maximum of 10 minutes after takeoff, thus enabling the determination of a maximum acceleration height
