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.
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).
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 ...
VFR over-the-top is different from VFR-on-top, in that VFR-on-top is an IFR clearance that allows the pilot to fly VFR altitudes, while VFR over-the-top is strictly a VFR operation in which the pilot maintains VFR cloud clearance requirements while operating on top of an undercast layer. [2]
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 ...
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]
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.
The flight visibility at the cruising altitude of the aircraft must be at least 5 miles and the weather at the destination aerodrome must be forecast to have a sky condition of scattered cloud or better, a ground visibility of 5 miles or greater with no forecast of precipitation, fog, thunderstorm or blowing snow, and that these conditions must ...
