INS,
We did not file a 1261, but in work today I took the matter up with TC Ops, who were "extremely concerned".
They are going to pursue this with BAW ops, so hopefully we can get this sorted soon.
Anyone for amending the AIP and MATS Part 1 to state:
"Any alternative clearance shall invalidate the previous clearance, except for clearances which contain level by or level abeam instructions, whereby the pilot will still be expected to maintain the vertical profile required to comply with the previous clearance"............or something along those lines?
It doesn't bear thinking about what chaos will happen if pilots are going to interpret the BAW memo so literally
Expedite
PS: This is also happening with pilots from Go as well.
