Hi Everyone,
When deciding upon a suitable alternate, is it possible to plan for an alternate which has holding (ie. INTER/TEMPO) provided it is above the alternate minima or must the alternate have no deteriations forecast regardless of whether it is above or below the alternate minima?
Also I have heard some sources that airlines have different requirements regarding the onset of INTER/TEMPO's when the a/c is enroute to the destination. Are some are required to divert to carry the holding fuel if not on board, while some believe that it is only a planning requirement and therefore it does not apply. Does this again revolve around whether the deteriation is above or below the alternate minima?
If anyone could please shed some light on the correct action for the above situations it would be much appreciated.
Thanks B.E.
