The main purpose of IFR is the safe operation of aircraft in instrument meteorological conditions (IMC). The weather is considered to be MVFR or IMC when it does not meet the minimum requirements for visual meteorological conditions (VMC).
A pilot's view of the runway just before landing in thick fog at night. In aviation, instrument meteorological conditions (IMC) are weather conditions that require pilots to fly primarily by reference to flight instruments, and therefore under instrument flight rules (IFR), as opposed to flying by outside visual references under visual flight rules (VFR).
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.
If they are not met, the conditions are considered instrument meteorological conditions (IMC), and a flight may only operate under IFR. IFR operations have specific training requirements and certification required of the pilot, and increased equipment requirements for the aircraft. Additionally, an IFR flight plan must usually be filed in advance.
Instrument rating refers to the qualifications that a pilot must have in order to fly under instrument flight rules (IFR). It requires specific training and instruction beyond what is required for a private pilot certificate or commercial pilot certificate, including rules and procedures specific to instrument flying, additional instruction in meteorology, and more intensive training in flight ...
Continued VFR into IMC is when an aircraft operating under visual flight rules intentionally or unintentionally enters into instrument meteorological conditions.Flying an aircraft without visual reference to the ground can lead to a phenomenon known as spatial disorientation, which can cause the pilot to misperceive the angle, altitude, and speed at which they are traveling.
An instrument instructor rating authorizes a certificated flight instructor to give training and endorsement for an instrument rating pilot. A multi-engine rating is required to fly an airplane with more than one engine.
An en-route (also known as en route [1] or enroute [2]) chart provides detailed information useful for instrument flight, including information on radionavigation aids (navaids) such as VORs and NDBs, navigational fixes (waypoints and intersections), standard airways, airport locations, minimum altitudes, and so on.
