Level Restrictions
Inbound AVANT for a Lorel 3C in STN this afternoon and issued the usual descent clearance to be level at FL190 by Avant. Approaching Avant we were given direct VATON. I would say we were passing FL220 at this point with around 10nm to run to AVANT. The FL190 abeam AVANT was not reiterated as part of the direct VATON clearance.
Could someone please point me in the direction of some official wording that would clarify the result expected by the controller. I know there have been previous debates pertaining to speeds and SIDs etc but I have not seen this be resolved by the CAA or NATS.
Thanks in advance....
