adrianchiasm created the topic: Holding or alternate
In this question context, there is only one ILS receiver. Shouldn’t you plan for an alternate instead because there is only one receiver and if that fails, u won’t have any more aid remaining.
Also, where do you get the info in the DAPs or ERSA saying about the traffic holding which require additional 20 mins of holding? I couldn’t find it after searching high and low for it. Are there any similar question to this which I can practice on? Are there also other aerodomes that implement this extra holding too?
The question didn't specify that you were a charter nor did it say you have no other aids. It simply said that you have only one ILS, so you don't qualify for the special alternate minima. However, I will change the stem of the question to make that more clear.
The 20min traffic holding is found in ERSA under Brisbane. It's a good idea to check for traffic holding in ERSA if you are arriving at any International Airport.
