Pilot Interview, Technical portion question

[Cherokee_Cruiser]

Here's a typical tech interview question, and I was wondering how one would go about handling this particular case:

ILS RWY 4 - LGA

http://204.108.4.16/d-tpp/0608/00289I4.PDF


Interviewer asks:

* Finger fly this approach (What would you say?)

* Where is the IAF, and FAF?

* If you have to go missed, what entry would you use to enter ORCHY?

1. Take finger and go down approach, talking them through it, if that's what they are wanting...ie., what altitudes, headings, and procedures, etc.

2. No real defined IAF, since it's RADAR required, if they push for an IAF, I'd say where they join you on the Loc. FAF is at glide slope intercept and OM (LG) (1319').

3. Going missed is easy, since the hold is the same course as the Loc. Either teardrop or parallel entry should be correct...I'd simplify it and say teardrop, since they are easier.

The previous post about said it all. The FAF is always the point where you intercept the glideslope on an ILS.

Good luck with your interview. Who is it with?

FAF is at glideslope intercept, outer marker has nothing to do with it.

Yeah, not sure why I put it in there...time for bed, I guess.

I'd say time for a drink! Jack and Coke do it for you?

Oh, no one. I read this from an aviationinterviews.com gouge, a guy was asked these kinda questions about the ILS rwy 4 at LGA, and I was curious as to how to properly answer those kinda questions.

It's the point that you have to be inside of to continue the approach if the weather falls below mins.

[Cherokee_Cruiser]

In the plan view panel, shouldn't "FAF" be put on top of the box that surrounds PETHS ?

Huh?

No because PETHS is identified as the FAF for a non-precision approach by the maltese cross in the profile view.

It's the point that you have to be inside of to continue the approach if the weather falls below mins.

He's talking about if you're operating under 121/135 rules, if the wx is reported below mins and you're outside the FAF you cannot shoot the approach. If it's reported below mins inside the FAF then you can continue.

Yea it has to do with the FAF, not the OM ( unless its the FAF)

This approach has no IAF, which is why it is RADAR required. It is designed specifically as "vectors to final only." This is sort of a slightly unusual and tricky thing, and I think that's why this approach is one that they ask about in interviews. They want you to catch stuff like that.

Going missed is not quite as easy as it looks. There is something to consider, which is that you probably need to switch your ADF equipment over. You probably had it set up on 332, to back up the glideslope intercept point when you were flying the approach, and to fly the missed you need to fly direct to ORCHY. This means that you need to put in 385, and hold a course based on the ADF/NDB/LOM--(These terms are all pretty similiar--reference AIM for the exact differences). Just flying the back course of the LOC is not legal for the missed, since you aren't guaranteed to receive it all the way out to ORCHY, and that's not how the missed portion is designed. That's probably another one of the tricks that they want you to catch as you "finger-fly" this approach.
