  2. Maximum elevation figure - Wikipedia

    en.wikipedia.org/wiki/Maximum_Elevation_Figure

    Pilots are also required to ensure their planned route does not contravene the minimum flying altitude regulations contained in CAR 167. This restriction is normally 1000FT above populated or built-up areas and 500FT elsewhere. Procedures are different when flights are conducted under IFR, where LSALT is commonly used.

  3. En-route chart - Wikipedia

    en.wikipedia.org/wiki/En-route_chart

    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).

  4. Instrument flight rules - Wikipedia

    en.wikipedia.org/wiki/Instrument_flight_rules

    In controlled airspace, air traffic control (ATC) separates IFR aircraft from obstacles and other aircraft using a flight clearance based on route, time, distance, speed, and altitude. ATC monitors IFR flights on radar, or through aircraft position reports in areas where radar coverage is not available. Aircraft position reports are sent as ...

  5. Flight level - Wikipedia

    en.wikipedia.org/wiki/Flight_level

    Therefore, a pressure altitude of 32,000 ft (9,800 m) is referred to as "flight level 320". In metre altitudes the format is Flight Level xx000 metres. Flight levels are usually designated in writing as FLxxx, where xxx is a two- or three-digit number indicating the pressure altitude in units of 100 feet (30 m). In radio communications, FL290 ...

  6. Standard instrument departure - Wikipedia

    en.wikipedia.org/wiki/Standard_Instrument_Departure

    Standard instrument departure (SID) routes are published flight procedures followed by aircraft on an IFR flight plan immediately after takeoff from an airport. SIDs are one of the two types of departure procedures (DP); the other type being Obstacle Departure Procedures. [1]

  7. CRAFT (aviation) - Wikipedia

    en.wikipedia.org/wiki/CRAFT_(aviation)

    The initial altitude is sometimes stated on the charts. If not, it will be given by the air traffic controller. The departure frequency is given to the pilot when ATC hands the aircraft over to the next sector. A typical IFR clearance would be: OOABC, cleared to Ostend via the DENUT 7C departure, climb flight level six zero, squawk four six ...

  8. Aeronautical chart - Wikipedia

    en.wikipedia.org/wiki/Aeronautical_chart

    An aeronautical chart is a map designed to assist in the navigation of aircraft, much as nautical charts do for watercraft, or a roadmap does for drivers. Using these charts and other tools, pilots are able to determine their position, safe altitude, best route to a destination, navigation aids along the way, alternative landing areas in case of an in-flight emergency, and other useful ...

  9. Instrument rating in the United States - Wikipedia

    en.wikipedia.org/wiki/Instrument_Rating_in_the...

    Under FAR 61.57, to be eligible to fly in Instrument Meteorological Conditions (IMC) an IFR-rated pilot must accomplish and log at least the following IFR procedures under actual or simulated IMC every 6 months: 6 instrument approaches. Holding procedures. Intercepting and tracking courses through the use of navigation systems.
