The VOR/LOC mode maintained the plane on a specific course, transmitted from a VOR (VHF omnidirectional range, a type of short-range radio signal transmitted from ground beacons) or Localizer (LOC) beacon selected by the pilot.The ILS (instrument landing system) mode caused the plane to track both vertical and lateral course beacons, which led to a specific runway selected by the pilot.KAL 007's divergence prevented the aircraft from transmitting its position via shorter range very high frequency radio (VHF).It therefore requested KAL 015, also en route to Seoul, to relay reports to air traffic control on its behalf.If, however, the plane was more than 7.5 miles (12.1 km) from the flight-planned course line when the pilot turned the autopilot mode selector from HEADING to INS, the plane would continue to track the heading selected in HEADING mode as long as the actual position of the plane was more than 7.5 miles (12.1 km) from the programmed INS course line.
The HEADING mode of the autopilot would normally be engaged sometime after takeoff to comply with vectors from ATC, and then after receiving appropriate ATC clearance, to guide the plane to intercept the desired INS course line. The INS mode was necessary for this route, since after Bethel the plane would be mostly out of range from VOR stations.The Soviets found the wreckage under the sea on September 15, and found the flight recorders in October, but this information was kept secret until 1993.The Soviet Union initially denied knowledge of the incident, The incident was one of the most tense moments of the Cold War and resulted in an escalation of anti-Soviet sentiment, particularly in the United States.Then, when over the Bethel beacon, the flight could start using INS mode to follow the waypoints that make up route Romeo-20 around the coast of the U. According to the ICAO, the autopilot was not operating in the INS mode either because the crew did not switch the autopilot to the INS mode (shortly after Cairn Mountain), or they did select the INS mode, but the computer did not transition from INERTIAL NAVIGATION ARMED to INS mode because the aircraft had already deviated off track by more than the 7.5 miles (12.1 km) tolerance permitted by the inertial navigation computer.Whatever the reason, the autopilot remained in the HEADING mode, and the problem was not detected by the crew.
