- Contexto
- As in the case of a Mode A/C transponder, inputs from an encoding altimeter are required for altitude reporting.
- Altitude is usually obtained from the pressure altitude encoder (also used as the data source for Mode C replies).
- Mode A/C transponders provide an identity (Mode A) code and pressure altitude (Mode C) code in response to radar interrogations. The spacing of the interrogation pulses determines the mode and hence controls the transponder response. The Mode A identity code, in the form of a four-digit octal number, is assigned by ATC and entered into the transponder by the flight crew. The transponder receives altitude from an on-board pressure altitude encoder or air data computer.
