Hello, when I plan a flight, from lets say Heathrow to Kennedy Intl, the route goes all the way to alaska and then it turns towards New York. Whats wrong? I canīt fly all the way to alaska from london and then turn back towards new york? Thats ridiculous lol 😕
BTW, I chose IFR flight and "High altitude airways" in the options.
The shortest distance on a sphere (The Earth) is a curved line called a Great Circle route. 🙂
I see, but the route goes so far west of alaska so that I almost end up in Russia. Then it suddenly takes a steep turn towards New York.
Thx for your help anyways 🙂
Why do you use high altitude airways?
Set to "Direct GPS"
I just took a look at the route that you are trying to fly, it's a misunderstanding of what you what and what the planner can accomplish. You are requesting high altitude routing via airways. High altitude airways require VOR stations on the ground to make up those airways. For an over the ocean flight, high altitude airways don't exist and are not flown. For an airliner to fly over the ocean, it must have GPS or FMC in order to navigate between waypoints over the ocean. The default flight planner can navigate these routes using the GPS but if you ask it to find airways, it will send you wherever it has to to use airways, it won't automatically find a over water route using waypoints. If you use a route finder, you can determine the waypoints for inclusion in the flight planner. If you don't want to go to all of that trouble, use GPS direct. It won't be exactly what the real aircraft fly but it will be close enough. 🙂
Acutally, I had no idea what high altidude and low altitude meant. I know that Direct GPS creates a straight line to the destination but I read somewhere that high altitude airways are what real airlines use so I chose that. Thank you very much CRJ for explaining what they mean 🙂
