Line up, line up and wait

By John Quarterman

 

COPA members are urged to familiarize themselves with all Aeronautical Information Circulars (AICs) on the Nav Canada website, ( http://www.navcanada.ca/ContentDefinitionFiles/Publications/AeronauticalInfoProducts/ AIP/Current/PDF/EN/part_5_aic/5aic_eng.pdf ) as part of any pre-flight preparations they do.

One such AIC was published recently and Nav Canada asked us to give this special mention.

In Canada the phrase we are all currently used to hearing on towered airports is:

"Taxi to position" or "Taxi to position and wait" when instructing an aircraft to enter the departure runway.

On April 10, 2008 Nav Canada Tower controllers will commence using a new phraseology that will be familiar to ICAO pilots but not to Canadians or Americans. That phrase is "Line up" or "Line up and wait." Below, an equivalency chart, taken from the AIC, shows the phraseology that pilots should expect after that date.

 

ICAO CANADA United States (FAA)
TAXI VIA (taxiway routing) TO HOLDING POINT RUNWAY (number) RUNWAY (number) TAXI VIA (taxiway routing) TAXI VIA (taxiway routing), HOLD SHORT OF RUNWAY (number)
LINE UP LINE UP RUNWAY (number), POSITION AND HOLD
LINE UP AND WAIT LINE UP AND WAIT (reason) RUNWAY (number), POSITION AND HOLD

 

It is important to realize that there is no operational difference between the phrase "Line up" and "Line up and wait." They both mean the same action, and the pilot must wait for Take Off clearance in either case. Please refer to the Nav Canada official version after April 10, 2008.
