To answer your original question ZAZOO, I have noticed a very slight improvement recently. Recieved Radar vectors onto the Loc at LOS the other day and Jepp have now published an ILS chart for PHC, and it seems to work most of the time. Runway lighting at PHC is still very poor. most of the problems listed already are still prevalent. Poor long range and enroute comms, often made worse by controllers not speaking into the mike(!) is still a problem. The worst habit is PHC controllers not clearing you to land until you have the runway in sight, even on an instrument approach! They still do that. Weather reporting at night is still non existent. The only thing that changes is the temp/QNH, the rest seems to be standard every night no matter what.
As I said, some slight improvements, but not much really.
