3. You are descending IMC on an ILS approach and have reached your DH, in order to legally continue the approach to your landing point, what must you have in sight?

A)PAPIs
B)REILs *Since all three are correct I was forced to choose this one*
A pilot may not descend to intended point of landing unless the runway environment is in sight, PAPIs will only allow you to descend to 100 above touchdown zone elevation unless you also have the red terminating bars in sight 91.175
C)Threshold lights
D)Both B and C This was the "correct" answer
This is the correct answer. A pilot may not descend to intended point of landing unless the runway environment is in sight, PAPIs will only allow you to descend to 100 above touchdown zone elevation unless you also have the red terminating bars in sight 91.175

Anyone see anything wrong about the supposedly correct answer? Here's 91.175:

(3) Except for a Category II or Category III approach where any
necessary visual reference requirements are specified by the
Administrator, at least one of the following visual references for the
intended runway is distinctly visible and identifiable to the pilot:
(i) The approach light system, except that the pilot may not descend
below 100 feet above the touchdown zone elevation using the approach
lights as a reference unless the red terminating bars or the red side
row bars are also distinctly visible and identifiable.
(ii) The threshold.
(iii) The threshold markings.
(iv) The threshold lights.
(v) The runway end identifier lights.
(vi) The visual approach slope indicator.
(vii) The touchdown zone or touchdown zone markings.
(viii) The touchdown zone lights.
(ix) The runway or runway markings.
(x) The runway lights.

Answer is correct. What do you see wrong with it? The question indicates leaving DH to a landing, not to 100 ft. above the TDZE. The wording is kind of funky though.

 

[GaTechKid]

Yep, the wording is funky. Answer D should have read "either B or C" - However, I wasn't aware that a Precision Approach Path Indicator was included in the ALS definition of 91.175. I always thought of it as a more precise VASI system and that the PAPI could be used like the VASI as a visual requirement to land.

 

[GaTechKid]

I still disagree with that answer so I asked a few instructors that I know about the use of a PAPI to descend to touchdown. All agreed that it qualified under the "visual approach slope indicator" of 91.175

There's an article on ipilot.com HERE that also confirms a PAPI as legal to use as a visual requirement. I'll be calling the FSDO on Monday as well to find out their opinion.

Don't bother, the PAPI IS included. That's not the point. You have to pick the MOST correct answer. I don't like the way they worded it either, but I still answered the question correctly. That's a test for ya. There's always a few questions like that.
