When to start descend from High Altitude Jet route?
I am wondering when jet liners should start to descend from high altitude jet route.
Is US, the high altitude jet route should be flown above FL180.
When pilots need to descend for landing, can you descend to below 18,000ft on jet route or need to transit to low altitude "V" route at 18,000ft before further descending?
