Alternate NA

Who knows. For a long time I also assumed you could use an A N/A airport if you could descend in VFR conditions as that is the way it was taught to me in the military. Maybe it was that way at one time... not sure.

Yeah, that's how they teach it. Wonder if its different for FAA vs mil, or standard across the board?

From good ol' 95-1...

f. Alternate airfield selection.
(1) An airfield may be selected as an alternate when the worst weather condition for that airfield is forecast for ETA
through 1 hour after ETA to be equal to or greater than—
...
(b) VFR minimums and descent from en route minimum altitude for IFR operation, approach, and landing can be made in VFR conditions.

(2) An airfield will not be selected as an alternate except per f(1)(b) above—
(a) If the approach procedure to be used at the alternate is shown not authorized (NA) in FLIP.

I guess that's why... I pretty much dumped AR 95-1 several years ago.

Oh me, too. The Googles helped me find this one. I was just curious because I couldn't remember and back then I remember having problems keeping the FAA and Rucker differences straight. Wasn't the rule 40 sec out on a procedure turn?

I stopped using it myself about 16 years ago, but I still have a current copy. My son flies UH-60's and I have to "set him straight" once in awhile.:) Dad's are always dad's.

Altimeter 70' off verses 75' off civilian was another. Or was it the other way around? I'm confused again.
 
For some reason I remember hearing that if your destination was served solely by GPS approaches then you needed an alternate but reading the AIM I can't find that anywhere...

Anyone remember?

Look in the IFH section 7. I believe it's in there.

It seems to change every time the AIM changes, so I would look at this section each year.
Under GPS approach procedures:

NOTE​

Any required alternate airport must have an approved
instrument approach procedure other than GPS that is
anticipated to be operational and available at the
estimated time of arrival, and which the aircraft is
equipped to fly.​

 
necro post, but I didn't think I needed to open a new thread. So, is there someplace that lays out why an airport would NOT qualify to be filed as an alternate? The only place that says an airport can't be used is the NA on the airport diagram. Why does it say NA? I've heard the "warm body on the field" answer, but where does it say that that IS in fact the answer?

The origin of the requirements is in TERPS, but it's easier to find them in secondary documents, such as the Instrument Flying Handbook, chapter 8:

When a triangle containing an “A” NA (NA) appears in the notes area, it signifies that Alternate Minimums are Not Authorized due to unmonitored facility or the absence of weather reporting service.
