All fine and good, but you must ALWAYS ask yourself the question:
"What will I do if the GPS fails right now?"
Dual redundant IFR approved systems are one thing, more basic VFR systems quite another. But both are EXCELLENT tools when used with respect for their limitations.
I wish that more of the pilots at my club could be bothered to learn how to use the panel-mounted GPS systems we bought for all the aircraft. The user guides are on our Yahoo! Newsgroup, freely available for members to download and study at their leisure. But even some of the FIs can't, it seems, be bothered to switch them on and use even the basic 'Direct to' function....
The CAA's CFE has now decided that an element of visual navigation must be included in SEP LPCs/LSTs. If a candidate wants to use GPS for that, that's fine by me - if he/she does so correctly.
