Net Take-off Flight The net take-off flight path is the gross take-off flight path
Path diminished by 0.8% climb gradient capability (or equivalent reduction in acceleration along that part of the take-off flight path at which the airplane is accelerated in level flight). The net take-off flight path must clear all obstacles in the take-off area by at least 35 feet vertically.
Climb Gradient The ratio of the change in height, during a portion of a climb, to the horizontal distance traversed in the same time interval.
Gross Gradient Climb gradient expressed as a percentage ratio, obtained using the following formula:
(Change in height ÷ Horizontal distance travelled) × 100
The gradients shown on the charts are based on true (not pressure) rates of climb.
Net Gradient The gross gradient reduced by the required margins.
First Segment The first segment starts from the 35-foot height and extends to the point where the landing gear is fully retracted, at a constant V2 speed and flaps in the take-off position.
Second Segment The second segment starts at the point where the landing gear is fully retracted up to at least 400 feet above the runway, flown at V2 speed and flaps in the take-off position.
Acceleration Segment The acceleration segment is the part of the take-off flight path that begins at the end of the second segment and extends horizontally over the distance required to retract flaps to zero, and accelerate to the final take-off climb speed.
Final Segment The final segment starts from the end of the acceleration segment and extends to the end of the take-off flight path, flown at the final segment climb speed, flaps up.
APR Automatic performance reserve – In the event of an engine failure during take-off, the APR function will increase the thrust rating of the remaining engine.
Centre of Gravity (CG) The point at which the airplane would balance if suspended. The CG distance from the reference datum is found by dividing the total moment by the total weight of the airplane.
GW Gross weight – The maximum weight to which the airplane is certificated.
