General background
Ground procedures
Ground Operations involve all aspects of aircraft handling at airports as well as aircraft movement around the aerodrome, except when on active runways. The safety challenges of ground operations arise in part, directly from those operations; for example, ensuring that aircraft are not involved in collisions and that the jet efflux from large aircraft does not hazard small ones.
Ground operations involve the preparation of aircraft for departure and must be done in such a way that the subsequent flight will be safe; for example, correct loading of cargo and baggage, sufficient and verified fuel of adequate quantity and quality and the correct use of ground de/anti-icing facilities where appropriate.
Controlled airports generally follow the same procedures for arriving and departing traffic. It's important to know who to contact for what, and what to expect when you do talk to them.
