What is IFR clearance in aviation?

An IFR clearance is an authorization for an aircraft to operate in the IFR System. The 5 critical parts of an IFR clearance are easily remembered using the acronym CRAFT, which stands for Clearance Limit, Route, Altitude, Frequency, and Transponder.

What is clearance limit?

Clearance Limits Formally, a clearance limit is the fix, point, or location to which an aircraft is cleared when issued an air traffic clearance. The clearance issued prior to departure normally authorizes flight to the airport of intended landing.

How do pilots talk to ATC?

The most common form of communication in aviation, very high frequency (VHF) radio calls are what we use for around 95% of our communications with ATC. In simplified terms, the transmitting station sends a signal that travels in a straight line and is picked up by the receiving station.

How long is an ATC clearance good for?

Usually two hours. But you can give ground or clearance a call and extend it. Two hours is the normal lifetime of a flight plan in the Flight Data Processing computer. Two hours from the proposed departure time, but that’s not the lifetime of a delivered clearance.

Who gives ATC clearance?

Section 4. ATC Clearances and Aircraft Separation. A clearance issued by ATC is predicated on known traffic and known physical airport conditions.

What does the symbol T with a black triangle?

What does the symbol T within a black triangle in the minimums section of the IAP for a particular airport indicate? A) Instrument takeoffs are not authorized. Takeoff minimums are 1 mile for aircraft having two engines or less and 1/2 mile for those with more than two engines.

What is the difference between a clearance and an instruction?

The difference between a clearance and an instruction is the word clear and that a clearance is effective when accepted, while an instruction is effective when received.

Is VOR required for IFR?

They are not considered ” required” for IFR flight, but most IFR routes can be flown using Victor airways and hence VORs. VOR approaches are now more deprecated but plenty exist – I just did one a few days ago! A VOR approach is like a localizer approach – non precision, with higher minimums.

How do I ask for IFR clearance?

What is in an IFR clearance?

Departures are described in an IFR clearance issued by ATC prior to takeoff. The departure clearance may contain an assigned heading, one or more waypoints, and an initial altitude to fly.

What is a clearance void time?

A pilot may receive a clearance when operating from an airport without a control tower that provides the clearance will be void if the aircraft is not airborne by a specific time. This time cannot exceed 30 min.

What are the maximum holding speeds?

International Civil Aviation Organisation (ICAO) maximum holding speeds are as follows: Holding altitude 14000′ or below – 230 KIAS. Holding altitude above 14000′ to 20000′ – 240 KIAS. Holding altitude above 20000′ to 34000′ – 265 KIAS.

When should I leave clearance limit?

(ii) If the clearance limit is not a fix from which an approach begins, leave the clearance limit at the expect-further- clearance time if one has been received, or if none has been received, upon arrival over the clearance limit, and proceed to a fix from which an approach begins and commence descent or descent and
