SAFETY EXTERIOR INSPECTION
An assessment should be made of the aircraft external environment before applying pneumatic or hydraulic power. Items to check include.
• wheel chocks, the parking brake must be applied if chocks are not in place,
• landing gear door positions
• APU Inlet and exhaust areas
• connection of external electrics
• connection of external
air-conditioning
This visual assessment is normally made when approaching the aircraft from ground level. However, where such an assessment is not feasible, co-ordination with the ground engineer must be established before starting the APU or activating aircraft pneumatic electric or hydraulic systems.
Double chocks should be positioned approx 2 inches forward and aft of the nose wheel. Main wheels must also be chocked if wind or ramp slope conditions require and/or if single type chocks only are used on the nose wheel. Be aware that the parking brake efficiency is significantly reduced if ACCU Press falls below 1500 PSI (amber sector.
EXTERIOR INSPECTION
The objective of the exterior inspection it to get a global assessment of the aircraft status. Any missing parts or panels should be checked against the CDL for possible dispatch and operational consequences. Ensure that main aircraft control surfaces are in no evidence fuel, oil or hydraulic leaks
Check the status of essential visible sensors. e. g. AOA pitot and static probes. Check the landing gear status e. g. Wheel/tyre condition, safety pins removed.
Check engine condition e.g. fan blades turbine exhaust, engine cowl and pylon status check all access panels are closed.
COCKPIT TO GROUND COMMUNICATE
It is essential that good communication is established with the ground personnel prior to engine start or push back. It is important that standard terminology is used to avoid confusion and ensure safety.
To attract the attention of the ground mechanic from the flight deck, use the mech call" pb. To speak to the Mechanic, use the "INT" key on ACP when wearing headsets or the "INT" Pb on ACP and the hand-mike Establish communication with the mechanic before commencing any action that may compormise safety e. g. Powering a hydraulic circuit.
