Non-discrete mode A code reserved use in mode S radar/ADS-B environment where the aircraft identification will be used to correlate the flight plan instead of the mode A code. [1] US: Used exclusively by ADS-B aircraft to inhibit mode 3A transmission. [3] US: Non-discrete code assignments in accordance with FAA Order JO 7110.65, 5-2.
When ground-based radar equipment [9] receives the IDENT bit, it results in the aircraft's blip "blossoming" on the radar scope. This is often used by the controller to locate the aircraft amongst others by requesting the ident function from the pilot, e.g., "Cessna 123AB, squawk 0363 and ident". [6] [7]
The civilian aircraft frequency for voice distress alerting is 121.5 MHz. Military aircraft use 243 MHz (which is a harmonic of 121.5 MHz, and therefore civilian beacons transmit on this frequency as well). Aircraft can also signal an emergency by setting one of several special transponder codes, such as 7700.
A piece of the wreckage of Air New Zealand Flight 901, which crashed in Antarctica in 1979, despite being equipped with a GPWS.All 257 people on the plane died. Beginning in the early 1970s, a number of studies looked at the occurrence of CFIT accidents, where a properly functioning airplane under the control of a fully qualified and certificated crew is flown into terrain (or water or ...

Light aircraft, helicopters, and fighters usually have limited space and mass capacity for additional equipment. The system may also cause adverse aerodynamic drag which demands minimal physical size and number of boxes. The power consumption must further be kept within the capacity of the platform's electrical system.
AAR-47 Sensors mounted on a USMC V-22 Osprey aircraft. The AAR-47 missile warning system consists of 4 Optical Sensor Converters (OSC), a Computer Processor and a Control Indicator. The system is relatively light at a total weight of approximately 32 pounds. [4] There is one optical sensor converter for each side of the aircraft.
The Honeywell HTF7000 is a turbofan engine produced by Honeywell Aerospace.Rated in the 6,540–7,624 lbf (29.09–33.91 kN) range, the HTF7000 is used on the Bombardier Challenger 300/350, Gulfstream G280, Embraer Legacy 500/450 and the Cessna Citation Longitude.
