Holding Patterns

Sun May 20, 2001 2:17 pm

Does the holding pattern radial go on the top or bottom of the OBS when you're setting up to intercept said radial?

For example-- if I wanted to hold on the 210 radial of Boiler VORTAC, would I place 210 on the bottom of the OBS?

I can't believe I'm asking this, I'm getting a brain fart right now.  Sad

Thanks!

Holding on the 210 Radial would mean your inbound course for the holding would be 030, right?
As you are flying to the station you have to set 030 on "top" of the OBS with a "to" indication in order not to get a reverse sensing indication!

The most common technique I see (and use myself since long time) is to locate the INBOUND (QDR) on the HSI, for the 210 radial, that would be to select 030 on that instrument, a short while before reaching that VOR station, and proceed to the station using the RMI at "12 o'clock" or so.
If you are talking about the "OBS", you must be dealing with light planes, which I am not familiar with as far as that type of instrument's standard use, or recommended procedure. I personally would do the same, select the INBOUND (QDM 030) -
Happy landings to you...

Thanks guys!

I do place 210 on the bottom of the OBS then.

And no I don't have an HSI or an RMI or what have you.  Sad I'm just flying Cessnas now, but in the future I hope to graduate up to those funky things you call FMCs!

NO!!!! It could go either way. It all depends which way you are tracking the 210 radial. If your inbound course in the hold was towards the VOR, you would have 210 in the bottom of the OBS. If you were holding on the 210 radial going away from the VOR, 210 would be on the top. If you remember nothing else remember this: RADIALS ONLY GO FROM A STATION. If you know that, remembering this little ryme will help everything. FROM top TO bottom. If you are going TO the station, the radial will be on the bottom. Hope I helped.

>>FROM top TO bottom

Thanks for that rhyme! I'm definately gonna use that in the future!

Thanks again! Don't worry, I know that all radials from VORs go FROM the station.

Just a reminder that although you will put the 210 at the top of the OBS for the intercept, you will want to turn it to the reciprocal 030 (210 at the bottom) before you turn inbound in the hold. Otherwise you will get reverse sensing.
