MARSHALLING SIGNALS
4.1.
From a signalman/marshaller to an aircraft
4.1.1.
The signals for use by the signalman/marshaller, with hands illuminated as necessary to facilitate observation by the pilot, and facing the aircraft in a position shall be:
(a) for fixed-wing aircraft, on left side of aircraft, where best seen by the pilot; and
(b) for helicopters, where the signalman/marshaller can best be seen by the pilot.
4.1.2.
Prior to using the following signals, the signalman/marshaller shall ascertain that the area within which an aircraft is to be guided is clear of objects which the aircraft, in complying with SERA.3301(a), might otherwise strike.
This signal provides an indication by a person positioned at the aircraft wing tip, to the pilot/marshaller/push-back operator, that the aircraft movement on/off a parking position would be unobstructed.
This signal is also used as a technical/servicing communication signal.
For use to hovering helicopters.
This signal is intended mainly for aircraft with the set of integral stairs at the front.
