Noise Abatement Departure Procedures

The following two Nose Abatement Procedures may be used during the initial climb sequence.  These profiles were formally known as ICAO ‘A’ and ‘B’ respectively.

Note that these profiles are only relevant for jet aircraft.
 

NADP 1:

- From runway to 800 feet AGL:

    *Takeoff Power & Takeoff Flaps
    *Climb at V2 + 10 to 20 Knots

- At 800 feet AGL:

    *Reduce to Climb Thrust & continue climbing at V2 + 10 to 20 Knots

- At 3000 feet AGL:

    *Accelerate to Flaps Up Speed
    *Retract Flaps/Slats on Schedule






NADP 2:

- From runway to 800 AGL:

    *Takeoff Power & Takeoff Flaps
    *Climb at V2 + 10 to 20 Knots

- At 800 feet AGL:

    *Accelerate to Flaps Up speed
    *Retract Flaps/Slats on Schedule
    *When flaps up, maintain Flaps Up speed + 10 knots maximum

- At 3000 feet AGL:

    *Accelerate to en-route climb speed
