Now I know that green badge holders can work throughout London, and yellow badge holders just in the suburbs.
Why then can't yellow badge holders pick up at Heathrow which lies in a yellow badge district?
Confused from Sussex.

Because, departing from Heathrow, 9 out of 10 times your destination is eastbound to a central London location, so a detailed knowledge of the area was deemed to be required.
Once you drop of you can start working again ensuring a good supply of taxi's is maintained up town.
The other reason being there would be no Yellow badges servicing the Ruislip / Uxbridge / Hillingdon area's of London as they would all be at the flyers.
The city airport however does allow Suburban drivers to operate the rank, but the turnover is miniscule in comparison to LH airport.
Not thinking of the knowledge by any chance sussex?
