CAP 413
Chapter 3: General Phraseology
Level Reporting

3.7 Only basic level instructions are detailed in this Chapter. More comprehensive phrases are contained in subsequent Chapters in the context in which they are most commonly used.
3.8 The precise phraseology used in the transmission and acknowledgement of climb and descent clearances will vary, depending upon the circumstances, traffic density and nature of the flight operations.
3.9 However, care must be taken to ensure that misunderstandings are not generated as a consequence of the phraseology employed during these phases of flight. For example, levels may be reported as altitude, height or flight levels according to the phase of flight and the altimeter setting. Therefore, when passing level messages, the following conventions apply:

1. The word ‘to’ is to be omitted from messages relating to FLIGHT LEVELS.

2. All messages relating to an aircraft’s climb or descent to a HEIGHT or ALTITUDE employ the word ‘to’ followed immediately by the word HEIGHT or ALTITUDE. Furthermore, the initial message in any such RTF exchange will also include the appropriate QFE or QNH.

Furthermore, the words FEET and FLIGHT LEVEL must never be omitted.

NOTE: Even though regulation states that the term “TO” shall be followed by altitude, it seems that the correct option does not state “Altitude”. Therefore, we would say that the most correct option is “Climbing to two thousand five hundred feet.” As there is no “Climbing to altitude two thousand five hundred feet” option available.
