Noise abatement departure procedure one (NADP 1), is designed to meet close-in noise abatement objective. At minimum 800' AAE reduce to climb thrust, continue with V2 +10 to maximum 3000' AAE. Maintain positive climb, accelerate and retract flaps and slats on schedule.
Noise abatement departure procedure two (NADP 2), is designed to meet distant noise abatement objective. At minimum 800' AAE maintain positive climb, accelerate and retract flaps and slats on schedule and set climb thrust (if not already done together with initial flap/slat retraction) and climb with Vzf +10 until reaching 3000' AAE.
