I read the Airport Briefing for GCLA - it said you should not consider an approach when you got Crosswinds of +15knots and variable winds, since there are strong wind phenomena where as the aiport is located at a ridgelige of mountains at the coast. I though give it a try although variable winds with gusts were reported.
I tried two approaches and had to go around since i couldt not bring the A310 down and had to go back to Tenerife.
The wind shears were humlitating the plane, and i saw metar reported gusts up to 34 knots.
I turned on thermal view of the weather and it showed the phenomena as described in airport briefing.
It is way harder than madeira and also stunning!
Try it yourself
