Instruments Procedures

Hi everybody,

I have a few questions on the way procedures are designed.

1. I've read with interest the lot of discussions about MSA but can't find a final answer, that is to say: is it legal to fly at the MSA once we're inside the 25 NM radius according to PANS-OPS? It seems to me that yes

2. What are the criteria that make that a base turn is sometimes preferred to a procedure turn in reversal procedure and vice versa? I can't find the rationale for that in PANS-OPS.

3. Similarly, what are the criteria that make that a racetrack procedure is sometimes preferred to a reversal procedure and vice-versa?

4. Are any reversal and racetrack procedures protected for any entry, or only for direct entries? If the answer is that it is protected for any entry, it means that it is possible to enter a racetrack or reversal procedurefrom an omnidirectionnal arrival, even an offset or parallel entry?

It is a lot of questions I know, but i hate not understanding the reasons why things are done....

Thanks a lot for your answers / highlights !
