What is????

[1.3XVso]

Not to be a wise guy but whats the distance in NM on the non protected side on a hold?

 

[DX Rick]

And you're the CFII?

What i mean is what is the guarantee protection that you may exceed the non protected side. This question came up and can't seem to find the answer.

I cannot remember offhand; it's been too many years. Try looking it up in the TERPS.

1.3X,


A cursory look at TERPS didn't turn up much. Acft-acft separation is defined in FAA Order 7130.3 ( whatever THAT is ) while TERPS defines obstacle clearance only with the holding pattern area being as defined in 7130.3 ( of course, that's only on alternate mondays in months containing the letter "R" ). I would guess you were interested in separation from other acft ??

TERPS says that it gives 1000' obstacle protection in the primary area and 500' in the secondary area ( 2nm wide surrounding the primary) at the inner edge tapering to zero at the outermost edge of the secondary area.

That's all I could stand...I could actually hear my brain cells cry out for mercy.

seems as though I once heard that there was something like four miles on the non-protected side. But it's 9:30 on a sunday.... sooo basically... I have no idea

yesimawesome~!

I thought it was 4 miles on protected side and one mile on the non-protected side, for the lower altitude holds anyway.

The protected area for the Non-Holding Side is 4nm and 10nm for the Holding side. I can't remember where I found this to give you a ref. I'll see what I can dig up...

If you click on Bobbysamd's "TERPS" link above, you'll find FAA Order 7130.3A detailing holding pattern construction. It doesn't appear there is one simple answer to the original question. It appears that pattern size varies with speed, alt, distance of the hold fix from the navaid, etc.


Para 2-9 says, " There are 31 holding airspace sizes." Good question from 1.3X, but no simple answer.

 

[100LL... Again!]

There are something like 26 different holding protected areas. It isn't worth it to try to remember them all.

Standard area on the unprotected side of a procedure turn is a whopping 4nm from the IAF all the way out to 10nm (or as noted).

Holds are probably similar. Much easier to just fly 'em right. Then you don't gotta know them details.

Kudos for being diligent enough to care, though.

while back on a slow day I drew the smallest holding template to scale as specified in FAA Order 7130.3A It had 3.2 nm of protected airspace on the non-holding side
