For non-GNSS equipped planes, there are no published straight-in instrument approaches for runway 07. Only the circling VOR 07.
However, in VMC the crew may request or likely be given a visual straight-in approach to 07.
As to why there aren't published minima for a straight-in VOR approach to runway 07, I can think of two plausible reasons:
- VOR accuracy being not good in that quadrant, maybe due to terrain interference, or interference from the tall church on short final.
- Winds almost always favor 25, so no effort was made to certify a straight-in approach using VOR for 07.
When an aircraft intends to land on a runway for which no instrument approach procedure exists, it may descend on the instrument approach to another runway and, provided the required visual references are established at the circling MDA/H, maneuver visually for landing on the desired runway. This procedure is used when landing on the instrument runway is undesirable, due for example to wind conditions or work in progress.
A circling approach is the visual phase of an instrument approach to bring an aircraft into position for landing on a runway which is not suitably located for a straight-in approach.
