GA Noise Abatement

Gulfstream V Noise Abatement Procedure
Santa Ana, John Wayne/Orange County, California (KSNA)

During any operations at Santa Ana, the following Noise Abatement procedures are required:

Daytime Hours
Departures: 7:00 AM [8:00 AM Sundays] – 10:00 PM
Arrivals: 7:00 AM [8:00 AM Sundays] – 11:00 PM
No restrictions
Nighttime Hours

Arrivals: 11:00 PM – 7:00 AM [8:00 AM Sundays]
Nighttime Takeoff:
  1. Limit aircraft weight to 77,000 lbs. for takeoff.
  2. Utilize Rated EPR and Flaps 20° for all takeoffs.
    1. Pre-takeoff: Select TRS menu on Display Controller panel, select MAN, set and box an EPR value of 1.21
    2. Plan takeoff using manual throttles set to TO EPR (i.e. full forward throttle)
    3. Align aircraft on the runway as close to the departure end as feasible.
    4. Hold brakes and advance power levers to approximately 1.1 EPR (LP=66%)
    5. Release brakes, rapidly advance power levels to Rated EPR.
    6. At VR, promptly rotate aircraft to a 13˚ nose-up attitude.
    7. Upon obtaining a positive rate of climb, retract landing gear, maintain 13˚ pitch attitude while accelerating to VSE.
    8. At 400’ AGL, retract flaps to Flaps 0˚ and maintain VSE, (minimum 13˚ pitch attitude).
  3. At 500 feet AGL, engage auto-throttle which reduces climb EPR to 1.21.
    1. Execute SID and/or departure instructions as closely as possible and continue climb to 3000 feet.
  4. At 3000 feet select auto EPR and accelerate to normal departure speed.
Nighttime Landing:
  1. Limit weight to 58,000 lbs.
  2. Set GPWS/GndSplr Flap Override to OFF prior to beginning approach.
  3. Fly approach to Flaps 20˚ and maintain 125 KCAS.
         NOTE: VREF for Flaps 20˚ approach at 58,000 lbs is 125 KCAS.
  4. At 200’ AGL, deploy Flaps 39˚

         NOTE: An EGPWS callout for “too low flaps” will occur at 245’ AGL.
