IF instrument flying. Also intermediate frequency
IFF identification friend or foe
IFR instrument flight rules prescribed for the operation of aircraft in instrument meteorological conditions (see below). Flight in most controlled airspace in the UK is conducted under IFR or Special VFR. Also used by military to denote in-flight refuelling.
IGE in ground effect. Helicopter performance with an earth surface immediately below. Also OGE, out of ground effect. Helicopters can hover at a greater maximum altitude IGE (above a mountain slope, for example) than they can in free air, OGE.
IGS instrument guidance system
ILS instrument landing system. The approach aid employing two radio beams to provide pilots with vertical and horizontal guidance during the landing approach. The localiser provides azimuth guidance, while the glide-slope defines the correct vertical descent profile. Marker beacons and high intensity runways lights are also part of the ILS.
IMC instrument meteorological conditions: weather below VMC minima, see below. Also associated rating used in conjunction with UK PPL.
INCERFA uncertainty phase of search-and-rescue procedure.
INS inertial navigation system. A gyroscope-based system which senses acceleration and deceleration and computes an aircraft's position in latitude and longitude with great accuracy. Used mostly by long-haul airliners, military aircraft and sophisticated business jets. Also IRS, inertial reference system.
INTER intermittent or fluctuating, term used in Met reports.
IR Instrument Rating
IRAN Inspect and repair as necessary
IRE Instrument Rating Examiner
IRT Instrument Rating Test
ISA International Standard Atmosphere -- a set of standard conditions or temperature and pressure which serve as a basis for comparison. ISA = pressure 1013.2 millibars, temperature 15 degrees C. Aircraft performance figures quoted by manufacturers are often based on such a 'standard day'.
