Yes it was procedure for
PR at one time, taxiway H2 in was closed so that required airlines with max t/o departures to have themselves towed to do the one eighty in order to use the full runway, we were behind one such departure and it did take up a lot of time, was fun to watch though. Later the procedure was scrapped because two flights (one
PR A340 and one KL 777) did manage to get their nosewheels off the pavement again. the madness stopped when the taxiway opened again sending everyone off the normal merry way.
