Approach Plate Ques. Hayden, CO and KPVD

[your_dreamguy]

Wondering if anyone could help me with these questions?

1. Hayden, CO KHDN

I'm pretty sure my charts are up-to-date. Why is "Special" written at the top of chart 11-7? Also, why is there an airport diagram on the back of 11-1 and 11-7?

Also, on chart 12-1 does anyone know what the "Y" in the RNAV GPS Y RWY 10 stands for and what does "Z" in the RNAV GPS Z RWY 10 on 12-2 stand for?

2. KPVD

On 10-7 of the special departure procedure for rwys 5 and 34, reads: "Engine failure prior to 1200' MSL: Fly runway heading to 400' MSL. Turn right heading 180. Then as assigned by ATC." Is it assumed that if you have an engine failure between 400' to 1200' MSL that you are to make an IMMEDIATE right turn to 180?

Thanks.

Hayden has been designated a "special" airport by the FAA, meaning a 121 operator needs to have an established familiarization program for its crews operating there. It is usually pictorials included in the plates, and the first entry for a CA may be with a checkairman.

I believe the "X" and "Y" designators are because there are multiple GPS approaches to the same runway.

Not sure about the airport diagram.

You are correct about PVD, an immediate turn would be expected.

You'll like Hayden, that is a spectacular approach on a nice day.

RNAV approaches are lettered from the back of the alphabet forward and LDA/VOR's are lettered from front to back to avoid confusion. Thus RNAV... Z and LDA... A.

So can you explain the ILS Z 18 and ILS Y 18 at DFW?

Same approach, same runway, but different minimums. The "Y" approach has different minimums for Cat "D" a/c, the "Z" one does not.

 

[VAjetlag]

Often Approaches are carrier specific and are also numbered or named differently. We have runways with much lower mins for the same Vis then others at some airports.

STRAIGHT-IN PROCEDURES​

When two or more straight-in approaches with the
same type of guidance exist for a runway, a letter
suffix is added to the title of the approach so that it
can be more easily identified. These approach
charts start with the letter Z and continue in
reverse alphabetical order. For example, consider
the RNAV (GPS) Z RWY 10R and RNAV (GPS)
Y RWY 10R approaches at San Francisco
International Airport. These two
approaches to the same runway are slightly different,
one includes an intermediate step-down fix
and the other does not; and one allows the use of
vertical navigation (VNAV) and the other does
not. In order to differentiate the approaches, the
FAA has labeled them Z and Y. This convention
also eliminates any confusion with approach procedures
labeled A and B, where only circling minimums
are published. The designation of two area
navigation (RNAV) procedures to the same runway
can occur when it is desirable to accommodate
panel mounted global positioning system (GPS)
receivers and flight management systems
(FMSs), both with and without VNAV. It is also
important to note that only one of each type of
approach for a runway, including ILS, VHF
omnidirectional range (VOR), non-directional
beacon (NDB), etc., can be coded into a database.​
