Antarctica Brief (NZFX)

Phoenix Field (NZFX)

There are two significant issues flying into NZFX:

1. There are no publicly available charts for NZFX.

2. There are misalignments between the available navdata and the scenery for the runway at NZFX.

We have mitigated these to the best of our ability.

To simplify operations the only active runway will be RWY 33T.

Williams Tower (NZWD_APP) will provide a surveillance approach service to Phoenix.

Headings

There are three ways of representing a heading in Antarctica. These are:

1. Magnetic - This is largely useless as due to the magnetic variation it swings widely causing you to fly a curved track if you were to follow it.

2. True - This points towards the true south pole at S090 E180. This is what all bearings will be given in.

3. Grid - This is a way of getting around the issue of many directions being south. A map grid is overlayed over the south pole and "North" is defined as pointing along the prime meridian.

Grid is what the phoenix runway is defined using, hence RWY 33T has a True bearing of 160T. You may see this as a small box in the top corner of your ND labeled "GRID".

We will be using True headings for all navigation. If your aircraft does not have a switch for true bearings advise ATC if you are requested to fly one and an alternate instruction will be issued. The True headings below do not align with the grid headings used to define the runway. Additionally the Runway drawn onto your ND may not align with the scenery. The recommended scenery is correct.

Procedures

The procedures we have designed are defined below in a textual format. You will need to load these manually into your FMC if you wish to fly them.
