holding pattern protected area

[matt152]

Hi all. Would anyone know where I can find the dimensions of the protected area for holding patterns? Is it specific to each individual hold? I am primarily interested in what (if any) obstacle protection there is on the non-holding side of the pattern.

Thanks
Matt

That's why they have speed limits for holds and as far as I know there is no obstacle protection on the non-holding side.

If you find some figures, please share with us.

I'm curious where you found the data?

Taylor FTW. And that would come out of TERPS.

FAAO 7130-3 "Holding Pattern Criteria " has the holding pattern sizes; the obstacle clearance data comes from TERPS.

Unfortunately, it is virtually imposssible to know exactly WHICH template for a holding pattern has been used, so you can't really say as you are flying around, "Oh, I have X miles of clearance on this side".

But, since template #4 is the smallest, you can always say, "I have at least X miles," which is worth something, I guess. In practice, though, I don't even think about it. I just do the hold following the rules, and assume that the TERPSter designed the hold following the rules.
