250k under 10000ft....

[Drew]

if you request to go faster while on the runway, and the request is accepted

take off, have flight etc

do you have to request the faster speed again before decending, or does the 1st request before take off last for the full flight?

thought i'd ask before i head off on a journey

once you climb aboce 10,000 feet you have to ask again.

thank you Sovek
