Question about NDB's

[PCL_128]

exactly. my question is, aren't you on the 225 bearing inbound to the ndb heading 045?

That's correct. You're holding SW on the 225 bearing from the station. The inbound course (no-wind hdg) would be 045. Clear as mud?

Just called the fsdo here in san antonio. they said that the controller would specify a hold on a radial(even though i made it perfectly clear we were talking non published ndb holds). when i corrected him and said bearing, there was silence and then he repeated that the controller would specify a radial. WTF? probably won't be calling those guys with anymore questions.

Answer to my quiz:

The original clearance:

Hold southwest of the ABC vor 045 radial 15 DME


Read the clearance very carefully - it is a valid clearance. You are not cleared to hold SW of the vor. You are cleared to hold SW of the 15 dme fix on the 045 radial.

Inbound course is 045.

The fix is not always the station - here it is a dme fix.

Hehe. I misread your clearance. I thought you were looking for 15 DME legs. Now that I know you meant a DME fix, it makes perfect sense.

Write when I point to not clearly make sometimes.

Lessons taking writing smarter look make me.

Ah! That explains it!

But it still was a valid clearance.

Yes, although arguably the controller giving the clearance didn't use approved phraseology. (Your point about Write when I point to not clearly make sometimes) From the ATC manual:

"HOLD (direction) OF (fix/waypoint) ON (specified radial, course, bearing, track, airway, azimuth(s), or route)."

which would translate to

"HOLD (southwest) OF (the 15 DME fix) ON (the 045 radial of the ABC VOR)."

There are a couple examples of this in the instrument knowledge test.
