I work at a CatI airport with stop bars,taxiway lights, ctrline lights and adequate approach lighting.
Lvps restrict access by vehicles to the rwy, limit the number of a/c we can have on the move at anyone time, increase pushback restrictions put the AFS on wx standby and increase the spacing between inbounds so that the rwy has been vacated before following a/c reach 4 nm on the approach.
What it means on the flight deck is that atc will not be expecting a/c to do anything expeditious. We`ll put you on the localiser a bit further out and be prepared for you to make a slower approach than normal so we`ll make an effort not to impose any speed control. We`ll probably give you instructions to follow in the event of a go-around but the biggest difference at a CatI airfield is you won`t have as pretty a view!!
