Can you explain what the 2nd caution on the LTAF VOR A chart means? "2. IF THE AIRCRAFT WILL MAKE A CIRCLING APPROACH VIA RIGHT TURN, ATC SHALL BE INFORMED AS SOON AS POSSIBLE." What exactly does this expression mean? I couldn't understand the use of "right turn" in particular. Because, although our main approach procedure is VOR A approach, is it meant to be described as a "Circling Approach" carried out from the north of the aerodrome? We see that the minimum value is also given as a circling, not a straight-in approach. Is this the 2nd caution written by considering VOR A approach as circling approach, or only the minimum value of VOR A approach is given as circling, and in fact, circling approach and VOR A approach are completely different things? I would appreciate it if you explain clearly by comparing the terms VOR A, circling approach, minimum value, and right turn. Here is the chart:
It means plainly what it says. A right turn is when you turn to the right. If you are going to make a right turn, you need to tell ATC as soon as possible that you are planning to do that. Since you are not authorized to turn left (as that takes you south of the aerodrome), this means you must notify ATC if you are not going to land straight-in.
Your related question asks why this has no straight-in minimums published. The reason is that there is an obstacle just south of the extended centerline in between the missed approach point and the runway threshold. This prevents straight-in minimums from being published. It does not prevent the pilot from flying straight-in if they have the runway in sight and have sufficient time to make a normal approach for landing.
In other words, this is an approach where they want you to approach runway 23 straight-in, but they can't promise you the obstacle protection that they would need to for a straight-in approach. So they give you circling minimums and ask you to land straight-in if you can.
