Read the airspace before the radio call.

1. Establish position and altitude

Begin with the chart or scenario: where is the aircraft laterally, and at what altitude will it operate? Many incorrect answers apply the right rule to the wrong layer. Check whether a boundary is inclusive, whether the floor changes along the route, and whether another airspace area overlies or underlies the position.

2. Define the operation

Flight rules, aircraft category, equipment, transponder and surveillance capability, navigation approval, visibility, cloud clearance, and pilot qualifications can change the requirement. List the facts before selecting the rule. Do not infer a clearance merely because communication has been established.

3. Identify the required service

Ask what the pilot needs: entry authorization, traffic service, a route clearance, weather information, an amended altitude, or an advisory. Then identify the facility capable of providing it and the point by which communication must be established.

4. Use a disciplined radio structure

A clear initial call normally communicates who is being called, who you are, where you are, and what you need. Subsequent transmissions should confirm the item that affects the flight path or clearance. Readbacks reduce ambiguity, but they do not transfer responsibility for aircraft control or compliance.

5. Separate clearance from safety

A clearance authorizes an operation within the air traffic system; it does not guarantee terrain, weather, performance, or aircraft suitability. The pilot must still identify an unsafe instruction, request clarification, and select an alternative when necessary.

6. Anticipate communication failure

Before entering a high-workload phase, know the next frequency, expected route and altitude, reporting requirement, and applicable lost-communication procedure. Preparation reduces the temptation to improvise when reception is weak or an instruction is missed.
