NDB service volumes

[DiverDriver22]

I know NDBs are rarely used these days but I'd still like to know what the abbreviations MH, H, And HH stand for respectively.

Thanks Cessnaflyer but I'm pretty sure it's not in there. With respect to VORs T is terminal, L is low, and H is high. That is written. But either it's not given or I'm not a very thorough reader because I can't seem to find it.

Medium high, high, and high high

Seems kind of too obvious. But I wasn't sure and I couldn't find it anywhere. Thanks guys.

Ha

Got those boxes checked on every single recurrent check ride I've taken while at 135 operators. I don't even have the luxury of a RMI

If you read through it there is a table there.

Sounds like the different coffee sizes at Starbucks! Whats an NDB?

No idea if what I wrote is true, but it's as good as anything else I've heard.

Medium high, high, and high high

This is what I was taught but then going through my CFII I was told that it was medium homing, high, and high homing...I never could really find anything to support this so I'm going to stick with what Roger, Roger posted.

Personally, anytime I deal with NDBs I generally only care about whether or not I can pick up ESPN radio.

I remember on my IFR checkride the DPE asked me what MH, H, and HH meant. I gave him the "homing" answer and he laughed and told me that as far as he knew the acronyms had no meaning...but that he asked all his applicants since he liked hearing creative answers.

From Cessnaflyers post:

TBL 1-1-2 NDB Service Volumes

Class Distance (Radius) Compass Locator 15 NM, MH 25 NM, H 50 NM*, HH 75 NM

Where I took my checkride, you'd better well know this stuff... I can't believe a freaking DPE didn't know this!

*edit* Apparently neither my phone nor I can spell...

HH = High Homing.

High High ---> Weed

Umm...the DPE and I knew the service volumes cold, it was the "meaning" of the acronym he was joking about.
