bobtait replied the topic: NDB requirement for a position fix above more than SCT
This is the sort of thing that makes me mad. I'm not sure if this came from a CASA question, but if it did it's a disgrace. Does 'within 30 miles exclude 30 miles? I believe that if you can't be 'within' 30 miles if you are 'at' 30 miles. Surely the people who write questions like this could find something more constructive to do with their time! If both NDBs are at 29.9 miles you can claim a fix, but if both are at 30 miles you cannot claim a fix. This is almost as stupid as the recent high court decision about dual citizenship!
In any case, apart from a 1950s full time fight navigator, who has ever even tried to plot a positive fix from two off-track NDBs while traveling at 3 miles per minute? Spare me!
