Capt Wally,
You wonder????? Of course it has an effect on other nav skills. My a/c does not have any radio nav aids, so its Map and Eyes around CTA and the 1 x GPS for cross country legs.
I should point out that not all the CTA & Restricted boundaries on the Jepp database in your GPS are that accurate. Most are likly to be within 100m however I have found over several updates (still
) that the Class C boundaries west of Brisbane and north of Amberley are up to a few miles different than the lines on the GPS
. So the old rule of skirting around with a buffer of a few miles is probably a good one!
