The Flight Safety section of International Civil Aviation Organization (ICAO) is responsible for PANS-OPS, [1] which outlines the principles for airspace protection and procedure design to which all ICAO signatory states must adhere. The regulatory material surrounding PANS-OPS may vary from country to country.
In 2005, the FAA assisted ICAO in its creation of a formal, internationally-accepted definition of a runway incursion. The new verbiage was first added to the fourteenth edition of PANS-OPS Doc 4444, but it was not until 1 October 2007, that the FAA finally adopted the ICAO definition. Previously, the FAA had maintained that an incursion only ...

The International Civil Aviation Organization (ICAO) classifies aircraft by their indicated airspeed at runway threshold (V at, [1]: II-5-1-3 also known as approach speed or V REF). The categories are as follows: [1]: II-5-1-3 Category A: less than 169 km/h (91 kt) indicated airspeed (IAS)
RNP procedures were introduced in the PANS-OPS (ICAO Doc 8168), which became applicable in 1998. These RNP procedures were the predecessor of the current PBN concept, whereby the performance for operation on the route is defined (in lieu of flight elements such as flyover procedures, variability in flight paths, and added airspace buffer), but they resulted in no significant design advantages.
Pan-pan calls may be made on the aircraft emergency frequency, but they are more often made on the frequency already in use, or another appropriate frequency. ICAO Annex 10, Volume V, § 4.1.3.1.1 states "the emergency channel (121.5 MHz) shall be used only for genuine emergency purposes". However, ICAO member states can deviate from this rule.
An "approach plate" depicting an instrument approach procedure for an ILS approach to Tacoma Narrows Airport in the United StatesIn aviation, an instrument approach or instrument approach procedure (IAP) is a series of predetermined maneuvers for the orderly transfer of an aircraft operating under instrument flight rules from the beginning of the initial approach to a landing, or to a point ...
In order to ensure unobstructed communication between the ANSPs, the European Air Navigation Planning Group (EANPG) of ICAO has defined 59 test cases in its EUR AMHS Manual (V5.0), 17/06/2010 (Appendix D, AMHS Conformance Tests), ASIA/PAC AMHS Manual (Annex B, AMHS Conformance and Compatibility Test, V2.0, 22/09/08) which have to be performed prior to establishment of bilateral links between ...
