New to GPS approaches; where's the MAP for this one?

[JimNtexas]

Would you believe I still don't know when to execute the missed approach?

If you are using a GPS that doesn't give vertical guidence then miss at RW3, if you have something like a Garmin 480 that has vertical guidence then miss at the decision altitude of 1320 feet.

Just be careful how far you trust that GPS. I know of several people who recieved violations by "blind trust" of the GPS navigation (such as Class B mapping, etc).
GPS is great, but still no replacement for good ole' piloting skills and proper SA. This is one of the reasons the FAA does not authorize stand-alone GPS operation.

I'm afraid I've been guilty of that one, myself, as far as airspace boundaries - which is one of the few things I used GPS for until recently. I have probably been WAY too trusting, in that respect.

what do you mean stand-alone gps operations? please clarify.

acaterry,
hmm it would be time to wakey and smell the coffee.....as I have shot many stand alone approaches ...GPS...as the plane I fly doesnt have an ADF....and YES THEY ARE AUTHORIZED....and condoned

I *think* what terry is saying is you CANNOT simply have a GPS installed in your aircraft and use that EXCLUSIVELY for navigation. You must have another backup receiver (VOR/ADF) installed in the airplane.

Ref: AIM 1-1-19 (d) (1) (b):

Aircraft using GPS navigation equipment under IFR must be equipped with an approved and operational alternate means of navigation appropriate to the flight. Active monitoring of alternative navigation equipment is not required if the GPS receiver uses RAIM for integrity monitoring. Active monitoring of an alternate means of navigation is required when the RAIM capability of the GPS equipment is lost.

I'm pretty sure that the Garmin 480 is authorized for sole-source navigation.

Certainly if an ADF can be used as a sole navigation source, it's not wild and crazy to trust a gps.

ETA: I think the AIM may not be totally up to date on this point, I'll look into it.

That's what I meant in my own little incomplete way of saying it. .
..seen too many a pilot violated over Class B mapping on the GPS in PHX...

Back to the question of when to do the missed approach.

Anytime you want to and no later than the RW03. If you pay attention to the distance on the GPS you can determine if you realistically can meet landing visibility requirements and may as well go missed then, certainly no later than RW03. For training purposes and check ride purposes, they probably are looking for RW03, just as if it was one of the other approaches at this airport where the end of the runway is the MAP. Don't get confused here. It's just another navigation aid, doesn't change the rules.
