Tha use of lat long co ordinates. Seems to be a forgotten art with modern GPS and the PPL world ?
Flying over vast areas of Africa and many parts of the world when flying airways there is little or no radar coverage means extensive use of lat long co ordinates.
Flying those airways and you will be streaming out long lists of lat long co ordinates to controllers with estimates and you will hear every other airline doing the same.
I do find it amazing that there is a reluctance to create user waypoints using co ordinates.
Yes there is room for error but that goes for inputting any nav or communication data.
How many times have you put in an intersection name only to mispel it and find you are heading somewhere 3000 miles away?
Using a Garmin 530 / 430 does allow you to create points with a cursor! more useful for skirting around shown blocks of airspace but the use of lat long co ordinates should not become a lost art as we become slaves to the direct to button on GPS units.
