The Instrument Trivia Thread

Here's a super trivial one: where can I find a list of continuous power facilities in the US? What are they for and what will they provide?

No takers? ;)

No new trivia to report that isn't specific to Army ops, but I have some complaints. Flying a full approach with a course reversal to an un-towered field. Switched to advisory. Did the approach, making CTAF calls as normal. During the debrief I was told I didn't make the required reports when not in radar contact per the FIH (which is regulatory and mandatory for us) but is stolen from the AIM:

5−3−3. Additional Reports
a. The following reports should be made to
ATC or FSS facilities without a specific ATC
request:

2. When not in radar contact.
(a) When leaving final approach fix inbound
on final approach (nonprecision approach) or when
leaving the outer marker or fix used in lieu of the outer
marker inbound on final approach (precision
approach).

Me: Sure I did - I announced on CTAF.

Him: Is that an ATC or FSS facilty?

Me: You have to be sh * tting me.

Him: It's in the FIH!

Me: So you really expect me to either call back up approach who already freq changed me or call up an FSS while I'm on the final approach segment in the soup with only one VHF radio? When was the last time you flew a real aircraft on a real IFR plan?

Him: 15 years ago.

Me: See you tomorrow.

Also - everyone here is under the impression the world is still a /U world. "So, how are you going to get your ground speed to adjust your MAP timing?"

The GPS.

No, no, no... pull out the wind face of your E6B and...

I'd have to know my ground speed first...

That's why you use the wind face!

I got that, but that also implies I know the winds...

You got the ATIS didn't you?

I'm at 2000 feet... those are surface winds. Look, it's one little click on the GPS right here if you'd just...

Just do the E6B!

Sigh... cooperate and graduate.

I seem to remember that's in the A/FD.

Yeah, continuous power facilities are listed in the AFD, in the "supplement" section. In addition to the obvious need to have some facilities that could continue to operate even in a massive power system failure, so that all the aircraft currently in flight could land, I believe that continuous power is a requirement for a facility providing CAT III operations.

* Edit: well clearly I'm wrong on the last point, since I see CAT III approaches to airports that are not listed as "continuous power".
 
Actually the second example in the aim uses the example of a helicopter flying at 130 kts needs to use Cat C

For what purpose, though? Same reason I don't bother with VDPs on a non-precision; don't need one, don't use one. Nor do I bother with circling mins, unless that's the only exiting mins, as I don't fly circling maneuvers in the classic "pattern to a runway" sense that an airplane has to: I maneuver to where I need to on the airport after I break out, and land, remaining laterally within the airports perimeter fence the whole time.
 
Ian. Were you ordered by Big Green to go to this course, or did you voluntarily sign up for this pain? :)

I must be an IP and an IE for my GS position. So I guess it's voluntary since I guess I really don't HAVE to have a job. Right, Obama? Right? Is this thing on?

There is no common sense allowed here! Quick! How much does the APU weigh?! How many times per minute do the upper and lower strobes blink?! How long does it take for the stab to slew from full up to full down?!

If you punch in without having these numbers down cold, YOU. WILL. DIE.

Of course in practice, but then again why would a helo be flying 130 on final anyways? I'm pretty sure if you helo drivers get lost you just "stop" and ask for directions. Amiright?

I was just responding to the question of what the mins are. If for some god forsaken reason a helo decided to fly an approach at nothing but cat C speeds then that's the mins that need to be obeyed.

I fly 130 or more on final quite often! 10-1-2 says I'm good with cat A mins.

Right here is where I would have pulled the chute on this conversation.......
 
Right here is where I would have pulled the chute on this conversation.......

Examiner (on airspace): Where is Class A airspace located, altitude-wise, and what equipment is needed to operate within it. Also, where does RVSM begin and what does it entail?

One of our OH-6A pilots, who never gets above 500 AGL, and has all of a single ADF for navigation capability: "Uhhhhhh, whut?? What are those?"

Examiner: Im troubled by the demonstrated lack of AIM airspace general knowledge of some of these pilots.......this is basic information they're required to know if they hold a pilot certificate!
 
Examiner: What's the service volume distance of an H-VORTAC?

OH-6A pilot: What's the TAC part? I don't think I have one of those navaids onboard....

Examiner: What is a Center Weather Advisory, and what areas does it cover?

OH-6A pilot: Center? That the 122.95 guy I call my fuel order into? They do weather also, in addition to the AWOS? Right on!
 
For @MikeD - since he loves sectional questions:

Significant terrain relief is generally shadowed a certain direction. Which direction and why?
