Browse and contact companies on AvPay, to find the most suitable and cost-effective option for your aircraft. Ensure your hangarage service provider is qualified and competent to handle your aircraft. Different aircraft have different operating procedures. You should check whether your handler has an International Standard for Business Aircraft Handling certification. This is an award given by the International Business Aviation Council. Use spotters where possible, to help you park your aircraft. Position them at the back of the aircraft and on each wing tip, so that you can ensure adequate clearance from other aircraft and obstructions. Use aircraft tugs where possible, to move aircraft more easily. Do not taxy aircraft into or start aircraft engines while in a hangar. Always chock your aircraft when in a hangar, in case gusts of wind enter the hangar through the doors. Be careful how you position the chocks, since farings can be damaged if tyres deflate. Take care around propellers and do not use them to push or pull the aircraft, until you have checked the Master Battery Switch is in the off position. Place drip trays under each engine cowling, to help you monitor leaks. Always use canopy cover, to prevent canopies from clouding over time through the effects of cosmic radiation. Hangarage can also be found by browsing the AvPay Airport Directory.
