APU Restriction

a) Fixed ground supply (400Hz): Aircraft operators are recommended to reduce electric load immediately after parking. 400hz ground power supply shall be connected no more than 05 minutes after on-block time. If fixed ground power supply is out of service, mobile Ground Power Unit (GPU) or Auxiliary Power Unit (APU) may be used with consent from Airside Operations by communicating through GHA operational control centre.

b) Fixed pre-conditioned air (PCA): Aircraft operators are recommended to turn off the cabin air re-circulation system to prevent outside air mixing with PC-Air. If fixed PCA is out of service,mobile Air Conditioning Unit (ACU) may be used with consent from Airside Operations by communicating through GHA operational control centre.

2.2. APU shall not be used more than 10 minutes before off-block time and 05 minutes after on-block time.

2.3. If the aircraft operator needs to run the APU more than the mentioned time length, they must seek approval from Airside Operations through GHA operational control centre. Any acts of non-compliance by the aircraft operator will result in actions being taken by the airport authority, including the assignment of parking stand to one not equipped with serviceable GSE pop-up pits.

2.4. Aircraft operators that would like to run the APU for an extended period shall notify the ground staff to ensure that they are prepared for the effect of extra ground noise.
