Hi Bob and richard.

I am actually heading to exam in 2 days. I hope you would see this post on time.

In the practice exam #3 Q.36 I would need some more help.

Isn't that we are not permitted to bring CAAP into the exam? I totally didn't have any idea about the answer which is ALA day operation 1: 20

cheers

Don't stress about that one. It actually goes back to PPL. The obstacle free gradient at the upwind end of an aeroplane landing area (ALA), is one in twenty (1:20). It is actually covered in the PPL Performance syllabus. The feed back I have had suggests that there will be no questions on ALAs in the CPL Air Law exam. However, it wouldn't hurt to remember it. 1:20 for day operations and 1:30 for night operations. It is true that you can not bring the CAAP into the exam room, so it wouldn't be fair to ask it in the actual CASA exam.

A little background to Bob's reply which may provide some perspective for the EOS requirement..

CAAP 92-1(1) presents a much more complex (and sensible) set of requirements than existed under the earlier rules for, essentially, paddock operations by light aircraft.

The original rules were fine but were pretty basic and relied on a bit of piloting commonsense, as did many matters in years gone by. As things developed many of the paddock strips transformed into the usual country airstrips of considerably higher standard than required by the then ALA rules.

The EOS (end of strip) 5% (1:20) gradient for ALAs dates back quite a few years. The operational relevance for light aircraft is that the (now defunct) local certification requirement for light aircraft (ANO 101.22, which survived for a while as CAO 101.22) required an AEO takeoff climb gradient of 6%. Between the two requirements, the aircraft had a reasonable probability of getting up and away from the terrain and other obstructions in the takeoff area.

In the early days of ALAs, I don't think anyone had much intention that they would be other than day operations.
