"In controlled airspace a pilot shall commence a change of level as soon as possible, but not later than 1 minute after receipt of instructions, unless a later time or place for commencement is specified or approved. A pilot shall report leaving a level which has been maintained for any period."
This is straight from Australian MATS so obviously not completely relevant to your Western Europen discussion however I do have a question reference the instruction "reach a level by a reporting point". Don't you guys have to use the word "requirement" somewhere in the instruction?
eg "Speedbird 234, descend to 9000, QNH 1013, requirement reach FL130 by DOTAP, report maintaining"
The examples before didn't seem to mention it. Just curious to see how you would phrase it. Thx
