Airways
Hello,
I've recently come to understand that there are airways and that there is a set of airways for high altitude and airways for low altitude. A few questions I have:
1. I would like to know how airliners transition from takeoff to get to their airway. Do they have to follow a set of low altitude airways to get to the higher airways, or do they just go straight there?
2. Can one waypoint exist at both high and low altitude airways
3. What are the height and width of airways? Seeing as atc can ask pilots to follow various headings or altitudes, I assume there is room for manoeuvre
4. On a slightly different note, how many waypoints are selected in a typical flight plan for short, mid and long haul flights?
I appreciate any answers and also happy if there are any links that give more insight.
