This Day in FAA History: December 24th

Full FAA Chronology at this link.
19631224: New York International Airport (known as Idlewild) was renamed John F. Kennedy International Airport.
19741224: FAA published a rule requiring installation of the Ground Proximity Warning System (GPWS) on large turbojet and turboprop airliners. The equipment was to provide both visual and aural signals when the aircraft was less than 2,500 feet above the ground. The rule’s implementation deadline of December 1, 1975, was subsequently extended due to persisting technical difficulties, but all major airlines were in compliance by the end of 1976. A rule published on October 10, 1978, extended the GPWS requirement to smaller commuter airline turbojets if able to seat as many as ten passengers. (See December 1, 1974, and March 17, 1992.)
