In aviation, instrument flight rules (IFR) is one of two sets of regulations governing all aspects of civil aviation aircraft operations; the other is visual flight rules (VFR). The U.S. Federal Aviation Administration 's (FAA) Instrument Flying Handbook defines IFR as: "Rules and regulations established by the FAA to govern flight under ...
Instrument flight rules (IFR) navigation is similar to visual flight rules (VFR) flight planning except that the task is generally made simpler by the use of special charts that show IFR routes from beacon to beacon with the lowest safe altitude (LSALT), bearings (in both directions), and distance marked for each route.
In aviation, a standard terminal arrival route (STAR) is a published flight procedure followed by aircraft on an instrument flight rules (IFR) flight plan just before reaching a destination airport. A STAR is an air traffic control (ATC)-coded IFR arrival route established for application to arriving IFR aircraft destined for certain airports.
In 1989 the very first commercially available off the shelf instrument procedure design software (Wavionix) conforming to ICAO document 8168 Pans-Ops was programmed by Ian Whitworth. This software was first demonstrated at Bailbrook College in Bath, England in 1992 to a procedure design course. Prior to this all procedure design was done with ...
Candidates for the instrument rating must be knowledgeable in IFR-related items in the AIM, the U.S. ATC system and procedures, IFR navigation, the use of IFR charts, aviation weather, requirements for operating under IFR conditions, recognition of critical weather, Aeronautical Decision Making (ADM) and Crew Resource Management (CRM).
Instrument Flight Rules (IFR) flight below 18,000 ft ASL when no other code has been assigned. [7] ICAO: 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 ...
A contact approach is an approach available to aircraft operating on an instrument flight rules (IFR) flight plan, where the pilot may deviate from the published instrument approach procedure (IAP) and proceed to the destination airport by visual reference to the surface. [1]
En-route charts are divided into high and low versions, with information on airways and navaids for high- and low-altitude flight, respectively. The division between low altitude and high altitude is usually defined as the altitude that marks transition to flight levels (in the United States , this is taken to be 18,000 feet MSL by convention).
