Instrument Procedure Question

[Hobiehawker]

On many GPS approaches there is a racetrack pattern outside the FAF. On the government charts there are distance marks (what I have seen usually 4nm) on the end of the outbound and inbound legs. On the Jepp charts they are not there. On a Garmin 430 it shows the racetrack.

Can you do normal timing as is any approach in this procedure or is there a distance requirement. My guess is that the depicted pattern is the protected area and as long as you stay inside that area you are ok.

Anyone have any input?

Thanks for all response.

I'm pretty sure that pattern is actual size since the 430 is IFR certified. What does it say in the manual? But really you should be doing the pattern on your own anyways, you will not always have a garmin 430 when you need to do a hold.

Give us an example of an approach to look up?

 

[Hobiehawker]

An example would be KORL RNAV (GPS) RWY 7

Then download the chart towards the bottom of the page.

Thanks

This particular approach requires a 4 NM leg outbound from the IAF when necessary. The requirement is depicted both pictorially and provided in a note found in the profile. Timing would then not be appropriate.

You said Jepp doesnt have this noted. Do you have a Jepp version of this approach? was it current?

 

[Lynxman]

I'm going to go out on a limb and say your not instrument rated yet. What you are seeing is a hold in lieu of a procedure turn so that you can get established on the inbound course. There is no timing in this hold you simply turn when your distance read off the 430 is 4NM from Esraq. At any rate your doing a course reversal so your just going to do the entry to the hold and once your established inbound then you continue in. Unless of course you need more time for whatever reason then you can do some laps in the hold. BTW I'm sure you know this, but just in case you don't fly the CDI; please don't fly off of the mini airplane and depicted pattern on the GPS screen.

 

[Hobiehawker]

The 4nm is not on the Jepp chart. Neither is the note. But it is, obviously, on the FAA chart. Which is the basis of the question.

Are you required to fly the outbound leg to 4nm before turning inbound for course reversal? Where as precision and non-precision are most often based on time unless depicted. And it would be equally as depicted on both the Jepp and FAA charts.

I bring up the Garmin 430 only because it looks like the pattern is about 4nm also.

I am instrument rated but consider myself always a student of aviation.

The Jepp chart does show 4 miles for the pattern if you look at the profile view of the approach.

 

[Hobiehawker]

Yep. And so it does. I was so focused on the racetrack I didn't look at the profile close enough. I am now rather certain you need to fly to the 4nm point. I wonder why?

Thanks for all who have participated.

Why not? This is a GPS approach - that means you always know how far from a waypoint you are. So instead of timing the holding pattern and adjusting and readjusting and readjusting to create that 1-minute leg, you just have a nice simple distance. That's standard for GPS holds. Doesn't that just make sense?
