I am in full flight to Gran Canaria airport, I took off from Madrid Barajas and I wanted to take off from runway 36L, so I did the Taxi procedure (until then no ATC present.
Then, when ready to line up, ATC is there, telling me to “turn around” and go to the other end of the runway to take off from Runway 18R.
I don’t know why he told me this when in real time (on FlightRadar24) even the planes were taking off from the 36L. And it seems to me that we can’t take off from the 18R.
I need some lighting, please.
