8/15/19 AIM  4 − 2 − 8. Figures EXAMPLE − 4 − 2 − 10. Directions EXAMPLE − EXAMPLE − 4 − 2 − 11. Speeds EXAMPLE − EXAMPLE − EXAMPLE − EXAMPLE − NOTE − 4 − 2 − 9. Altitudes and Flight Levels 4 − 2 − 12. Time EXAMPLE − EXAMPLE − The three digits of bearing, course, heading, or wind direction should always be magnetic. The word “true” must be added when it applies. The separate digits of the speed followed by the word “KNOTS.” Except, controllers may omit the word “KNOTS” when using speed adjustment procedures; e.g., “REDUCE/INCREASE SPEED TO TWO FIVE ZERO.” Radio Communications Phraseology 4 − 2 − 6 EXAMPLE − a. Figures indicating hundreds and thousands in round number, as for ceiling heights, and upper wind levels up to 9,900 must be spoken in accordance with the following. b. Numbers above 9,900 must be spoken by separating the digits preceding the word “thousand.” c. Transmit airway or jet route numbers as follows. d. All other numbers must be transmitted by pronouncing each digit. e. When a radio frequency contains a decimal point, the decimal point is spoken as “POINT.” ICAO procedures require the decimal point be spoken as “DECIMAL.” The F AA will honor such usage by military aircraft and all other aircraft required to use ICAO procedures. a. Up to but not including 18,000 feet MSL, state the separate digits of the thousands plus the hundreds if appropriate. b. At and above 18,000 feet MSL (FL 180), state the words “flight level” followed by the separate digits of the flight level. The separate digits of the Mach Number preceded by “Mach.” 0920 UTC zero niner two zero,  ..... zero one two zero pacific or local, or one twenty AM 1. (Magnetic course) 005 zero zero five ...... 2.

EXAMPLE − a. FAA uses Coordinated Universal Time (UTC) for all operations. The word “local” or the time zone equivalent must be used to denote local when local time is given during radio and telephone communica- tions. The term “Zulu” may be used to denote UTC.
