NOISE ABATEMENT DEPARTURE PROCEDURESFOR JAA / EASA OPERATORSENGINE FAILURE CONSIDERATIONSGeneralAll takeoff performance in the Airplane Flight Manual assumes that anengine fails at or after V1. With this in mind, should an engine fail ator after V1, the PF should follow the AFM procedures for an enginefailure during takeoff.a. Maintain directional control.b. After a positive rate of climb is established, call for gear retraction.c. Climb at V2 to V2+10 kt until a minimum of 450 m (1,500 ft)above the departure airport elevation before commencing theEngine Failure Checklist. Should any turns be required asmandated by ATC for terrain or traffic or as mandated by theStandard Instrument Departure Procedure for terrain clearanceor airspace limitations, maintain a minimum speed of V2 toV2+10 kt while in the turn.Engine Failure During an NADP 2 ProcedureShould the engine failure occur during an NADP 2 procedure above240 m (800 ft) during or after flap retraction, accelerate to VSE andcontinue the climb using either climb power or MCT if necessary toclear obstacles to a minimum of 450 m (1,500 ft) above the departureairport elevation before commencing the Engine Failure Checklist.STANDARD DEPARTURE PROCEDURE GUIDANCEIf the operational limitations above preclude the use of either theNADP 1 or 2 procedures, the following guidance is offered. Thisprocedure was developed during the certification process for all of theapplicable models and meets noise abatement requirements at mostairports.This procedure involves initiation of flap retraction on reaching theminimum prescribed altitude. The flaps are to be retracted onschedule while maintaining a positive rate of climb. The powerreduction is to be performed with the initiation of the first flapretraction. At the prescribed altitude, complete the transition tonormal en-route climb procedures.BASIC ISSUEGAC-OMS-02Aug 29/07 Page 7
