GA Noise Abatement

When in noise-sensitive areas, the following noise abatement procedure is recommended:

1. Set takeoff power prior to brake release.
    
2. Perform normal takeoff through rotation and liftoff.
    
3. Establish and maintain initial climb speed of + 20 KIAS.
   

   This climb speed will normally require an 18 º to 20º pitch attitude. Limit pitch attitude to 20º for passenger comfort.

   
    
4. Perform thrust cutback to 90% RPM at 400 to 1000 feet AGL depending upon local airport noise sensitivity.
   

   Under some ambient conditions, the cutback thrust setting may not provide the required climb gradient in the event of an engine failure. If an engine should fail, advance remaining engine thrust to takeoff EPR.

   
    
5. Continue climb at the above conditions until clear of noise-sensitive area or 3000 feet AGL.
   Then set climb thrust and accelerate.
    
6. Retract flaps at + 30 KIAS and accelerate for normal climb.
