  • Storage Periodic Ground Checks
  • RTS after Parking period
  • RTS after Storage period
  • Mooring

Aircraft Protection Equipment

  • Do not apply adhesive tape on the probes, ducts, or sensors (Static, Pitot, TAT, AOA).
  • Use only the specified tools for the protection of the aircraft.

Wheel Chocks

  • Removal/Installation – AMM
  • Use chocks that agree with the SAE AIR4905 standard.
  • Approach the a/c after the beacon light is off.
  • There must be a small distance between the tires and the chocks.
  • Weight changes can have an effect on the wheelbase, which can cause the tires to catch the chocks.
  • If the aircraft is parked on a slope, Make sure that the down-slope chocks touch the wheels and that the up-slope chocks do not touch the wheels.
  • On slippery surfaces, or in strong wind conditions, It is recommended to apply the parking brake. The parking brake has sufficient pressure for 12 hours.
  • Number of chocks requirements – Local regulations/AMM
    • Aircraft in Flight Ready Condition with
      • Wind Speed less than 25 KTS : Both outer main wheels – Front & Behind
      • Wind Speed more than 25 KTS : All wheels – Front & Behind
    • Aircraft in Parking or Storage condition
      • All wheels – Front & Behind

MOORING

  • The purpose of mooring is to prevent damage to the aircraft on the ground in high wind conditions.
  • For wind speeds less than 50 knots – Mooring is not necessary.
  • For more than 50 knots – Do the mooring as per AMM.
