2  Arriving flights

2.1 IFR flights entering and landing within a terminal control area will be cleared to a specified point and instructed to contact approach control at a specified time, level or position depending on traffic situation. The terms of this clearance shall be adhered to until further instructions are received from approach control. If the clearance limit is reached before further instructions have been received, holding procedure shall be carried out at the level last authorized as applicable.

3  Departing flights

3.1 IFR flights departing from controlled aerodromes will receive initial ATC clearance from the local aerodrome control tower. The clearance limit will normally be the aerodrome of destination. IFR flights departing from non-controlled aerodromes must make arrangements with the area control centre concerned prior to take-off.
3.2 Detailed instructions with regard to routes, turns, etc. will be issued after take-off.
