ILS Quiz
How well do you know your ILS approaches? See if you can answer these questions about the ILS approach for runway 5 at KAND
Can this approach be flown without DME?
AIM 1-2-3 allows a suitable RNAV system to substitute Distance Measuring Equipment (DME)
Which of these is not an initial approach fix?
OWUXO does not have an (IAF) and is therefore not an intial approach fix. It is, however, the final approach fix.
You pass the final approach fix and notice the glideslope is no longer working. Can you continue the approach?
If the glideslope becomes inoperative during the approach, the pilot may continue the approach given they utilize the localizer minimums and adhere to the non-precision altitude restrictions of the approach. This includes adhering to the minimum descent altitude (MDA).
Upon reaching the decision altitude, what side of the runway would you expect to see the PAPI lights?
Looking at the diagram of the airport in the bottom left of the approach plate, a letter P inside a circle on the left side of runway 5 can be seen. This denotes the PAPI lights are on the left side of the runway.
You are being vectored to final on a heading of 120 at 5000 feet. Approach tells you to turn left heading 080 and join the localizer. What altitude should you descend to after receiving these instructions?
Because you have not received an approach clearance, and only instructed to join the localizer, you cannot comply with the altitude resctrictions of the approach plate and therefore must maintain the last assigned altitude of 5000. Once you receive an approach clearance or are given another altitude restriction, then you may descend.
