Abstract: Methods and systems are disclosed for preventing aircraft collisions with forward looking terrain avoidance (FLTA) functionality based on a terrain avoidance profile used to evaluate potential terrain threats based on the projected flight path of an aircraft in flight, and a clear terrain profile to determine whether the terrain threat has been cleared. If the terrain avoidance profile conflicts with terrain, a collision threat may exist whereby the pilot is notified and a terrain avoidance maneuver is executed. During the terrain avoidance maneuver the clear terrain profile extends in a direction substantially parallel with the horizon at or near the present altitude of the aircraft to check whether it is safe to return to the previous flight path angle or otherwise end the terrain-avoiding maneuver. When the clear terrain profile no longer conflicts with the terrain threat, a terrain clear indicator is then issued to the pilot.

Abstract: Systems and methods relate to an aircraft with a CAS that may be employed to enhance pilot awareness. The CAS may be employed on a formation member aircraft to provide a TA that is distinctive for an intruding formation member aircraft, as opposed to a TA provided as a result of an intruding nonmember aircraft. The CAS may also provide a plurality of status indications for aircraft engaged in airborne refueling, as well as aural indications of the present mode of operation for the CAS.

Abstract: A system includes a first processor that performs a first self test process in response to a first actuation of a provided test control by a user of the system and a second processor that performs the second self test process in response to a second actuation of the test control prior to lapse of a first predefined period of time and terminates the second self test process in response to a third actuation of the test control by the user of the system, wherein the third actuation is maintained for more than a second predetermined period of time. In effect, a single test control formerly dedicated to a legacy processor is actuated to activate and control self testing of an additional processor.

Abstract: A method and apparatus for recording data concerning a system is provided. The apparatus comprises a memory card, such as a COMPACTFLASH card, and a processor unit, such as a T2CAS processor unit. The memory card includes a supplemental file that contains instructions as to what data is to be recorded and when the recording should start and stop. To conserve space the supplemental file is written as a sequence of hexadecimal characters whose position in the sequence and binary bit value indicates which data is to be recorded and when. A lookup table can be used to interpret the supplemental file. The processor unit includes or is coupled to a memory card reader/writer.
