c) The phrase 're-cleared' should not be employed.
d) When transmitting messages containing flight levels each digit shall be
transmitted separately. However, in an endeavour to reduce ‘level busts’ caused
by the confusion between some levels (100/110, 200/220 etc.), levels which are
whole hundreds e.g. FL100, 200, 300 shall be spoken as “Flight level (number)
HUN DRED”. The word hundred must not be used for headings.
NOTES:
1
Use of the word 'hectopascal' for pressures lower than 1000
2
Transmission of Regional Pressure Setting (Wessex) limited to regional name
and pressure.
