I'm amazed at some of the stuff in this thread...
If an air traffic controller instructs a pilot to fly a heading, he expects the pilot to use his compass or gyro (or whatever) and NOT - DEFINITELY NOT - to take into account the wind effect. Radar controllers are perfectly capable of adjusting the headings they issue to take account of the wind. Golf Bravo Zulu... don't know where you've been but in 31 years I never once used the cursor on a PPI. Everything came out of my head, as it does with most controllers.
When I worked in Heathrow Tower and wanted to take someone off a SID for separation I would give them a heading to fly instead of "straight ahead", or "runway heading". I had taken account of the wind and knew pretty well where the aircraft would go. Maybe they don't teach ATCOs basic navigation skills nowadays?
