Starting today, whenever you ask for the METAR enroute from A to B, you’ll also get a link to map showing you very useful info.
Check it out with this Route from Rochester,NY to Kalamazoo.
Or with this other Route From Miami INTL to San Francisco INTL. Ain’t that GREAT?
(The later is a good example of a great difference between the straight -projection- line and the orthodromic line)
The orthodromic (great circle) is the line we use to calculate the distance and true course.
Enjoy!
