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.
