What is the function of a SELCAL decoder?

A SELCAL decoder is connected to each aircraft’s radio receiver. When a SELCAL decoder on an aircraft receives a signal containing its own assigned SELCAL code, it alerts the aircraft’s crew by sounding a chime, activating a light, or both.

What is the SELCAL code?

SELCAL is a signaling method which can alert an individual aircraft that a ground station wishes to communicate with it. SELCAL codes are assigned to aircraft operators and not to individual aircraft. Aviation Spectrum Resources (ASRI) is the registrar of SELCAL codes worldwide.

Where is SELCAL located?

flight deck

What are the advantages and drawback of using higher frequencies?

Answer: Advantages: smaller antennas, less interference, more bandwidth. Disadvantages: shorter range, can’t get signals through walls and windows.
