A code indicating a transponder mode.

Source: EUROCONTROL-FAA AIXM v.5.1

Properties:

Properties	Definition	Type
MODE_1	Mode 1 provides 2-digit 5-bit mission code. (military only - cockpit selectable)	enum value
MODE_S	Mode S provides multiple information formats to a selective interrogation. Each aircraft is assigned a fixed 24-bit address. (military and civilian) Mode S, or mode select, despite also being called a transponder radar system replacement for Air Traffic Control Radar Beacon System (ATCRBS), is actually a data packet protocol which can be used to augment ATCRBS transponder positioning equipment (radar and TCAS). Mode S is designed to fully interface with ATCRBS systems: mode S SSRs can interrogate ATCRBS transponders, and AIS-P transponders will also reply to older ATCRBS and TCAS interrogations.	enum value
MODE_C	Mode C provides 4-digit octal code for aircraft's pressure altitude. (military and civilian)	enum value
MODE_5	Mode 5 provides a cryptographically secured version of Mode S and ADS-B GPS position. (military only)	enum value
MODE_4	Mode 4 provides a 3-pulse reply to crypto coded challenge. (military only)	enum value
MODE_3A	Mode 3/A provides a 4-digit octal identification code for the aircraft, assigned by the air traffic controller. (military and civilian)	enum value
MODE_2	Mode 2 provides 4-digit octal unit code. (military only - set on ground for fighters, can be changed in flight by transport aircraft)	enum value
