Airmanship II Communication Aids and Airspace
Communication Aids We shall Discuss in this lecture, • RADAR • DRDF • ILS • Airspace • Airways
RADAR • RAdio Detection And Ranging. • Transmits a pulse of energy and listens for an echo with a receiver. • The information is displayed visually on a cathode ray tube
DRDF • Digital Resolution Direction Finding • It receives an transmission from an aircraft and displays it on a CRT as a green line called a “trace”. • Controllers direct the aircraft to a point above the airfield and from there control its descent through cloud (CDTC) to a height and position on the approach. The pilot can either land visually or employ a runway approach aid.
ILS • Instrument Landing System. • Transmits a radio beam which acts as a path.
Airspace • Used to manage and control air traffic. • Airspace is divided into classes, or functional areas. • Some have strict rules on the conduct of flying within them: they are termed “Controlled Airspace”.
Airways • These a part of the air space system. • They are imaginary tunnels in the sky. • They are between 10 and 20 nautical miles wide. • Marked by beacons. • Permission to use airways is sought from ATC.
Crossing an Airway • Fly below the airway, no permission needed.
Crossing an Airway • Fly through, requires clearance.
