HANKE-Aviation GmbH - Flight Crew Training




Report to air traffic control, as soon as practicable, any event that may affect ability to comply with the current clearance, examples being: severe turbulence, loss of thrust, loss of pressurization, need to divert, uncertainty of present position, etc. If, at any time, it is not possible to notify air traffic control immediately that a problem has occurred and obtain a new clearance before departing from the old, comply as accurately as possible with any procedures that may be specified for the airspace. In all cases a good look out should be maintained, and if the aeroplane is equipped with TCAS, the visual display should be used to assist in the sighting of proximate traffic. The following equipment failures must be reported to air traffic control:

ATC shall render all possible assistance to a pilot experiencing an in-flight contingency. Subsequent ATC actions will be based on the intentions of the pilot, the over-all air traffic situation, and the real-time dynamics of the contingency.


In this RVSM airspace, it is expected that all aeroplanes will be in continuous radio contact with ATC either on the assigned frequency or on the distress and emergency frequency (121.5MHz). They will therefore be able to advise ATC of any abnormal circumstances where RVSM performance requirements cannot be met, including encounters with turbulence greater than 'moderate'. ATC will then respond and issue an appropriate revised clearance before the pilot Initiates a deviation from the original clearance. It is recognized, however, that there may be some circumstances (such as an emergency descent following the loss of cabin pressurization) where deviations may have to occur with little or no prior notice to ATC. In such cases the pilot will need to obtain a revised clearance as soon as possible after the deviation.
