Why not ??? After we reach 10000 ft , can`t you fly indefinetely at 10000ft?? Why proceed so desperately to the alternate???
You turn right30š get yourself out of RVSM , and request vectors to your alternate , in this case left on track.
Procedures are done to be complied with. Otherwise they are useless.If everybody do whatever they want it would be a mess.
Why don`t you comply with air traffic control regulations , but you comply with SOPīs?
Of course , the PIC in an emergency situation can do whatever he needs to guarantee flight safety , but none of all the predictable failures we normally can have like rapid depressurization , EO cruise , DualBleed fault , etc are a reason not to comply with procedures.
