Wind and runway assignment by ATC on Caucasus map

[Volator]

At Anapa it seems ATC always assigns runway 22 regardless of wind direction up to 3 m/s. At 4 m/s or higher, at respective wind direction, runway 04 will be assigned.

 

Is that a bug or intentional? At Sochi the same issue appears, but like in real world here it makes sense due to the mountains at the end of runway 06, so even with a tailwind a takeoff in direction 24 is desireable. For Anapa however, I cannot see any particular reason why you would want to take off with a tailwind component. Even more so, a take-off on RWY22 means you take off towards the beaches and hotels, which most probably wouldn't be very desireable with regards to noise, and certainly would not justify a tailwind take-off, so I'd assume this is a bug.

Some additional tests at Krymsk, Maykop and Mozdok:

Krymsk, wind 220/3 --> RWY04

Krymsk, wind 220/4 --> RWY22

 

Maykop, wind 220/3 --> RWY04

Maykop, wind 220/4 --> RWY22

 

Mozdok, wind 080/3 --> RWY26

Mozdok, wind 080/4 --> RWY08

 

So it seems every airport has a main runway that is assigned by ATC regardless of wind direction up to 3 m/s. That means in certain wind situations you will always get a tailwind take-off and landing at 3 m/s or less. At 4 m/s the correct runway will  be assigned.

Caucasus has long-standing issues with arbritrary wind speed and direction limits determining which runway is assigned the active, and which ILS is turned on/off.

When I was discovering Caucasus aerodromes, I always went for wind 5 m/s roughly in the opposite direction of the preferred runway for that aerodrome. That reversed most of them, and turned on the right NDBs - or disabled NDBs if they were only on one side. I have the following kneeboard pages from all this testing, I'm not sure how understandable they are without explanation. I also used and tested the information from those great DimOn frequency/aerodromes maps.

Mine are much rougher and are also more focused on L-39 (like the radio channels).
