IFR GPS as clock for ifr flight

[PropsForward]

I hate GPSs, I hate GPSs, I hate GPSs, I hate GPSs...

all they do is p*ss me off! Especially those dman approaches!

Give me an ILS or an NDB even! Keep me away from a GPS and their f*cking approaches!

HAHA! Got a little GPS Air Rage action going on here!

If you can run a PC and download a song from the internet, you can run a GPS.

Technophobe!!

Funny thing is I can shoot a GPS approach but I haven't had any luck with downloading songs fromthe internet. Something to do with the firewall or some nonsense.

I agree with one quibble. RAIM is only required to fly a GPS approach. RAIM is n/a in cruise flight, and many GPS units that are approved for enroute and terminal only don't use the RAIM feature at all.

RAIM performs a computation that predicts the number and geometry of satellites available at the time the box expects to fly the approach.

Not quite correct. If you have RAIM enroute, then you do not need to monitor your alternative navigation system. If you do not have RAIM enroute, then you do need to monitor your alternative navigation system.

Secondly, RAIM doesn't perform any predictions. The box performs calculations to predict RAIM availability. Confusion about what RAIM is is quite common I've found.

Lastly, and unrelated to my previous comments, the lesson plans from Garmin for the 430/530 suck.

Oh, and if your box uses WAAS, then you don't need RAIM, ever, unless WAAS is unavailable. But that's beside the point.

GPS units take some time to get to know. You really have to get into the manual and learn the different features and how they relate to your flying.

Absolutely!
You have to learn some of it in the real world, but you really need to understand the functions of your unit before you try to use it in flight. THe manual is a good place to start, and there are simulators you can download form Bendix and Garmin - the Garmin sim I've used for the 430 is terrific. You can fly from one city to another - try all the different functions, even 'shoot' an approach. Definately helps the situational awareness. I am positive if you build o up some familiarity you will not mind GPS useage at all.

'course I'm still happier with a ILS myself, but thats just because I think GPS and glass cockpits are the 'anti-aviator' and the spawn of the devil. Give me stream gauges, or give me death! ; )
