Click the question to see the answer

1. If intending to land on RWY 09, what is the landing distance available?

8,300 feet as noted in the second line in the appropriate box.

2. What minimum ceiling and visibility would you need to achieve a successful landing if completing the ILS 09 Approach; and is an approach ban a possibility on this approach?
A minimum ceiling of 200’ and ½ SM. And yes, an approach ban is a possibility due to the fact that this RWY is RVR equipped as is noted in the minima box (RVR26).

3. To fly this procedure for a straight in approach either via the KAXUG or SATIL transitions, your aircraft must be equipped with:

An IFR certified GPS is required to fly the depicted transitions. Note “GNSS Required” below the text boxes.

4. In the event of a missed approach, what would be your course of action upon arrival at the clearance limit (ATURU) prior to receiving further clearance?

Hold as published at 5000’, via either an offset or parallel entry.

5. The glidepath is U/S and the active approach now reverts to the LOC/DME. You are established inbound on the localizer at 4000. At what point are we legal to commence descent out of 4000?
7.1 DME, note the highlighted box indicating this.

6. Relative to the above question, with your GPS indicating a groundspeed of 120 knots, what should be your target sink rate from 7.1 DME in an effort to fly a constant descent angle (CDA) approach?
With a groundspeed of 120 we interpolate between 110 and 130, and this results in a target descent rate of 635 FPM.
