HXdave,
Another option would be to park up by multiflight cafe which is open to the public and serves tea, coffee and fairly good food albeit a little pricey. Turn off to the right about 100 Yds before the A658 tunnel road as you travel from Yeadon (should be signposted anyhow) under the Rwy.
And directions to otley chevin as follows.
Follow A658 to airport from Rawdon / Yeadon under runway and when you get to the roundabout carry straight on. Travel along the A658 passing the heliport and keep going for about a mile until you get to some traffic lights at a cross road, turn left here. Travel along here"Otley Old Road" for approx 1/2 to 3/4 of a mile and you should see a signpost for the Chevin Lodge and a turn to the left "York Gate Rd" take this left and again travel along here for another mile or so, you will go past the entrance for the Chevinl Lodge and about another 200 or 300 yards along you will come accross the Royalty Pub on your left. Park up here and buy a pint and if Runway 14 is in use for landings then enjoy.
