En-Route ATC
A. Dialogue
B. Terminology Practice
affirmative:a term used to indicate assent Affirmative, Jet 567, you're cleared to land. Affirmative, your squawk code is 1234. Is that an affirmative? area navigation (RNAV):a navigational system in which aircraft fly on a desired course within the limits of navigational signals When we pass St. Louis, ask ATC for RNAV routing direct to New York. With a direct RNAV routing, an aircraft can save fuel. How do we request an RNAV flight plan? distance measuring equipment (DME):electronic equipment used to measure the distance between an aircraft and a VOR DME is usually located at VOR stations. When is distance measuring equipment used? The DME indicates that we're 120 miles from the Honolulu VOR. flight level (FL):a level of atmospheric pressure, stated in three digits that represent hundreds of feet You're cleared to flight level 330. Are we cleared to descend to flight level 240? FL 250 represents an altimeter indication of 25,000 feet. go ahead:to proceed with; or, approval to proceed with Beech 56XY, go ahead with your message. Is that a go ahead? The controller said, "go ahead." out:a term used to indicate the completion of a radio message Your message was received, out. We received the weather report, out. Did that pilot say "out"? position report:a pilot's report of the physical location of an aircraft We'll make a position report when we pass over London. The copilot already completed the position report. Our position report should mention that we're five minutes ahead of schedule. say again:a term used to request that a radio message be repeated Please say again your messages. Control, our expected arrival time 1230, say again. I did not hear your transmission, say again. stand by:a term used to indicate that a radio message is due in a short time Stand by for your IFR clearance. This is Frankfurt Center, please stand by for the amended weather report. Should we stand by for clearance to take off? VHF omnidirectional range station (VOR):a navigational aid that provides 360 courses using VHF radio waves The course to the VOR is 120 degrees. Is the VOR frequency 114 degrees? Since VORs use VHF radio waves, they're subject to line-of-sight restrictions.
