Take-off procedures (VFR) – Part 1

At busy aerodromes with separate GROUND and TOWER functions, aircraft are usually transferred to the control tower at or approaching the runway holding point.

Since misunderstandings in the granting and acknowledgement of takeoff clearances can result in serious consequences, care should be taken to ensure that the phraseology employed during the taxi manoeuvres cannot be interpreted as clearance to enter the runway or to take-off.

Some aircraft may have to carry out checks prior to departure and are not always ready for take-off when they reach the runway holding point.

The takeoff clearance will include always the runway designator.

For traffic reasons it may be necessary for the aircraft to takeoff immediately after lining up.

Conditional clearances shall not be used for movements affecting the active runway(s), except when the aircraft or vehicles concerned are seen by both the pilot and the controller. When a conditional clearance involves a departing aircraft and an arriving aircraft, it is important that the departing aircraft correctly identifies the arriving aircraft on which the conditional clearance is based. It may be necessary to add a description of the colour or company name to ensure correct identification.

A conditional clearance is given as follows:

  1. call sign;
  2. the condition;
  3. the clearance;
  4. brief repetition of the condition.
