Which of the following IAPs will NOT have a published VDP?
a. circling approaches
b. an approach with an MDA based on part-time or full-time remote altimeter settings
c. an approach where the visual descent angle would pass below a required altitude at a step-down fix
d. an approach where the VDP would be between the MAP and the runway
e. any of the above.

What are the optimum and maximum non-precision final segment descent gradients?
a. 300'/nm and 380'/nm
b. 318'/nm and 400'/nm
c. 400'/nm and 500'/nm

What are the minimum and maximum distances for a DME arc that serves as an intermediate approach segment?
a. 5 nm and 25 nm
b. 7 nm and 30 nm
c. 9 nm and 35 nm

What is the maximum difference between the course to be flown in the intermediate approach segment and the final approach course?
a. 0
b. 10 degrees
c. 20 degrees
d. 30 degrees
e. 45 degrees

Fill in the blanks in the following sentences: The obstacle clearance in the initial approach primary area shall be a minimum of ____ feet. In the secondary area ____ feet of obstacle clearance shall be provided at the inner edge, tapering uniformly to zero feet at the outer edge.
a. 2000, 1000
b. 1500, 750
c. 1000, 500

What is the total width of the initial approach segment that is within 50 nm of the facility?
a. 6 nm
b. 8 nm
c. 10 nm
d. 12 nm

What is the minimum angle of the courses or radials for an intersection holding fix if the facilities are less than 30 miles apart?
a. 30 degrees
b. 45 degrees
c. 60 degrees

Which of the following is not a possible name for an IAP?
a. VOR/DME
b. LOC/DME
c. ILS/DME

What are the optimum and maximum descent gradients for the intermediate approach segment (in feet per nautical mile)? NOTE: The maximum may be exceeded for a localizer approach published in conjunction with an ILS procedure. In this case, a higher descent gradient equal to the commissioned GS angle (provided it does not exceed 3°) is permissible. Higher gradients resulting from arithmetic rounding are also permissible.
a. 150'/nm and 318 '/nm
b. 200'/nm and 424'/nm
c. 300'/nm and 636'/nm

d.) They are all possible names for an IAP.

I assume the answer you were looking for was "C."

But alas, I found an ILS/DME approach in Bardufoss (ENDU), Norway. Plate is here.

I was walking around the airport today and thought, "Who will respond to that TERPs quiz?" And then I though MarshMan would be perfect candidate, that guys knows his [censored]. And alas, here you are. How's things going?

What they were looking for in that question was that the DME function of stating that in the approach pertains only to the Localizer only approach. Apparently no ILS has to be flown with DME because the MAP can be found with proper altimeter setting while on the glideslope.

Haha. Those are some tricky questions, I haven't had time to tackle them all. Things are going alright. Trying to find some kind of more steady flying job. I hooked back up with my old company, and even though they had already hired my replacement, they said they'd try to get me on some trips soon. I'm also diligently bugging a local freight-hauling company that has a decent-sized fleet. Aside from that, not much luck with the job search. Hows things going with you? Keeping busy, it sounds like!

Yeah, I figured thats what they were looking for. Now here's a piggyback question...why is the ILS/DME at Nashville an ILS/DME instead of an ILS that just says, "DME Required" in the notes section?

Is it because the DME is the substitute for there being no OM?
 
Well, TWITY, the FAF for the LOC-Only approach is identified with DME. All of the step-down fixes are identified with DME. That, however, wouldn't make any difference.

The reason this is an ILS/DME approach vs. an ILS with DME required, is that the Localizer has DME colocated with it.

If it said "DME Required" instead of ILS/DME, it would mean that DME from some other NAVAID is used on the approach or on the missed.
 
Does anyone know how they come up with the descent gradient on an ILS or any other approach? Like 2.75 degrees or 3 degrees descent graidient on the ILS.

It is probably something easy, but my brain is farting and I can't seem to figure it out.

Thanks
 
Those that I have seen like that require DME for something other than identifying the MAP. I'll bet it has a DME arc or a waypoint associated with the MAP procedure that forces the identification of the procedure to DME aircraft only.

I haven't been able to see the MEM approach though. Thoughts?

Oops,I meant Nashville.

The DME station being a different station or not colocated makes a ton of sense. NICE
