Indicated Altitude
The altitude shown on the altimeter when it is set to the current local altimeter setting. Indicated altitude is not the same as cabin pressure altitude; supplemental-oxygen rules follow the pressure altitude the occupants experience in the cabin, which can differ in pressurized aircraft.

- Instrument CurrencyThe recent instrument experience required under 14 CFR 61.57(c) to act as PIC under IFR or in weather conditions less than VFR minima. Instrument currency is separate from the flight review and from passenger takeoff-and-landing currency; an Instrument Proficiency Check can restore it when experience has lapsed.
- Instrument Proficiency Check (IPC)An instrument proficiency evaluation with an authorized instructor or examiner under 14 CFR 61.57(d). An IPC restores instrument currency when a pilot has not met recent instrument experience requirements and is distinct from the broader flight review under 61.56.
- Instrument RatingAn FAA rating added to a pilot certificate that authorizes the holder to act as pilot in command under instrument flight rules (IFR) in instrument meteorological conditions. Requirements include instrument flight training, actual or simulated instrument time, a knowledge test, and a practical test.
- Instrument TimeFlight time logged when the aircraft is controlled solely by reference to instruments, either in actual IMC (actual instrument) or under a view-limiting device (simulated instrument). Instrument rating applicants must log required instrument time under 14 CFR 61.65, and some of it may be credited in an approved simulator or training device.
