Approach Clearance?

I'm posting this in general, because I want the traffic.

Your clearance is:

"N123AB, cleared direct to MEGPE, cross MEGPE at 3000, cleared RNAV 11 approach." What do you do at MEGPE? When can you start a descent below 3000?

Discuss.

You aren't cleared for the full procedure?


Why not just exactly as stated? Direct on FMS to MEGPE, cross it at 3,000 and make sure you can do 1,800 feet down in 6 miles for LABIY. At MEGPE, start down out of 3,000.

Other way around. Unless cleared for a straight in approach you are required to do the full procedure... unless it says NoPt of course.

Granted, I *think* the .65 says something different than the FARs but it's been a while since I've been down that rabbit hole.

Have gotten RNAV approaches just that way, and I've done just that. Direct to fix, cross fix at assigned altitude, and start down. Considering the traffic behind us coming into the approach as well, I'd have a hard time seeing a full procedure turn. Not saying you're wrong, but doing a circle there would most likely surprise the controller.


To be honest the only time I recall full procedure turn was at the regional, going to uncontrolled airports like SCE (UNV), which is now towered. But back then, Ny approach would sometimes be lazy and have us do the full turn. Explicity, if I recall. We requested vectors, they said negative and "expect full approach"

The key here is the arrow. Because he is coming to MEGPE at less than a 90 degree intercept no PT is required or expected. A PT allows you to be cleared direct at greater than a 90 degree intercept where you fly the PT.
 
Why are we talking about a procedure turn? I don't see one.

Cross MAGPE at 3,000 and at final approach speed, drop the gear and flaps and start your let down. You have to go straight in.
 
It's a hold in lieu of procedure turn, which means you just do the entry to the hold and shoot the approach. Since it's a direct entry, cross MEGPE at 3,000 tun 112 descend and intercept vertical guidance at 1800 and half dot.

The 90 degree thing is the difference between FAR/AIM and the .65 I think. There's no reference to that on our end of things. The only place it might apply is with a TAA type approach.

Lighten up Francis!

The note
to section 5-4-9-a adds: “If the pilot is uncertain whether the
ATC clearance intends for a procedure turn to be conducted or to allow
for a straight-in approach, the pilot shall immediately request
clarification from ATC (14 CFR Section 91.123).
 
Seems to get brought up a lot. From what I've learned it would be to make the procedure turn then shoot the approach. Logically that doesn't make sense given where you're coming from and I'm sure ATC just wants you straight in. If they don't make it clear by saying straight in, just ask
 
Only 10 yrs in 121 operations (not a whole lot) but I've never had any procedure turn on a relatively straight in, as in this case. The only procedure turn approaches I did were at the regional to smaller airports, and it was explicitly cleared as such for the full approach, and we were coming from the opposite direction where it was obvious a PT was necessary. And when we did do a PT, it was fairly obvious from the instructions of ATC.

In this case, you are almost direct to the fix anyway. Cleared direct to the fix, maintain 3,000 to that fix, and cleared for the approach.

And this, right here, is why the MPL is a terrible idea.
 
And it says it right there, you're not expected to do a PT if one of 3 conditions, one of which is:

"When ATC provides a radar vector to the Final approach course "

Which is exactly what I implied with the regional airline approach into SCE (UNV) in which we were told to expect a full approach for Rwy 24. I asked for radar vectors and he wasn't able (New York center, not approach, good catch). We were coming in from ppposite direction, and it was fairly obvious from the setup and lack of radar vectors to final that we would be doing a PT, and the controller was expecting it too.
