What do pilots say to ATC before landing?

Phrases tower controllers say: “Line up and wait” (taxi onto the runway and wait for a takeoff clearance) “Cleared to cross runway two seven” (taxi across runway 27) “Fly heading two three zero, Runway two seven Left, Cleared for takeoff” (After takeoff, fly a magnetic heading of 230º.

When an ATC clearance has been obtained?

(a) When an ATC clearance has been obtained, no pilot in command may deviate from that clearance unless an amended clearance is obtained, an emergency exists, or the deviation is in response to a traffic alert and collision avoidance system resolution advisory.

What is clearance delivery in aviation?

Flight data and clearance delivery Clearance delivery is the position that issues route clearances to aircraft, typically before they commence taxiing. These clearances contain details of the route that the aircraft is expected to fly after departure.

Why do pilots say Niner?

Aviators often speak “pilot English” to avoid miscommunications over radio transmission. “Tree” for instance, means three, “fife” is the number five and “niner” means nine, says Tom Zecha, a manager at AOPA. The variations stemmed from a desire to avoid confusion between similar-sounding numbers, he says.

Why do pilots say heavy?

Thus, the term “heavy” (unlike light, medium and large) is included by heavy-class aircraft in radio transmissions around airports during take-off and landing, incorporated into the call sign, to warn other aircraft that they should leave additional separation to avoid this wake turbulence.

What is the purpose of ATC clearance?

An ATC clearance means an authorization by ATC, for the purpose of preventing collision between known aircraft, for an aircraft to proceed under specified conditions within controlled airspace.

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.

Do VFR pilots use clearance delivery?

Clearance Delivery For VFR departures, the request is similar to that for taxi clearance. You tell the controller who you are (your aircraft’s N-number, where you are on the airport, and where you want to go, i.e. “west departure” or your destination airport.

What is clearance void time?

Used by ATC, the time at which the departure clearance is automatically canceled if takeoff has not been made. The pilot must obtain a new clearance or cancel the IFR flight plan if not off by the specified time.

Why 9 is Niner?

Pilots and air traffic controllers say niner instead of nine to distinguish it from other numbers. Radio transmissions may not be crystal clear, and with any disturbances on the frequency, nine could be easily confused with five, given they are one-syllable and rhyme.

Why do pilots say uhh?

I’ve always heard/believed, not just in th aviation world, that it’s an old crutch to prevent the beginning of a received transmission from being missed — by using a throwaway word like “and” or “uhh” to give the receiver something to break squelch before any actual info is transmitted.

What kind of landing clearance can I get from ATC?

When you’re “cleared for the option”, you can pretty much do it all. ATC authorizes you for a touch-and-go, stop-and-go, low approach, missed approach, or a full stop landing. So when would you use this?

What does ATC stand for in air traffic control?

Used by ATC to space an aircraft from the one in front. Land on the specified runway. This is the one and only clearance that authorizes an aircraft to land . Abort the landing and fly the published missed approach. Used when a controller deems that the landing would be unsafe. The pilot aborts the landing and flies the published missed approach.

When does air traffic control give a clearance?

Reduced Runway Separations is in use and the criteria for issuing the landing clearance are met. The previous traffic will have left the runway when the following aircraft crosses the threshold.

When do you need to give landing clearance?

Usually, the clearance is given when the runway is clear of traffic or, at least in Europe, when two conditions are met: Reduced Runway Separations is in use and the criteria for issuing the landing clearance are met. The previous traffic will have left the runway when the following aircraft crosses the threshold.
