Is XPD mode C always taken from same side ADC?
Altitude Reporting (Mode C)
The “ATL RPT L/OFF/R” control is a three position toggle switch. It
selects the air data computer (ADC) source for the transponder to
reply with coded altitude information. In the L position the left ADC
is used, while in the R position the right ADC is used. In the OFF
position no altitude information is being used.
Does RH AP use RH ADC regardless of LH ADC being the active (normal)?
FCC/AIR DATA COMPUTER INTERFACE
Two air data computers provide air referenced data to the Autopilot
Flight Director System (AFDS). The left air data computer ( ADC)
supplies data to the left and center FCC and the right air data
computer supplies data to the right FCC. Each ADC transmits a source
destination identifier ( SDI) code to identify the source of the data.
Does JAR require use of side matched ADC and APs?
Sorry, can't help you on that one! I'm just an engineer.
