A lot of airlines operate the 737 into Jersey from the 200 up to the 800.
Yes there are some restrictions the 400 with a full load inbound has one stab on the ILS and then diverts.
The runway length is 1706 Metres.
British Caledonian brought in there Airbus 310 all those years ago for the same reason fog delays.
From what I can make out there was restrictions on the L1011 and it goes like this, it could only bring in a small load but take out a full one,and it was only certain Tristars that could do the trip as some of them had differant flap settings I think.
A 737 landed on Rwy 27 the other day inlight winds and turned off at the apron intersection and that would be less than a 1000 metres.
So a 737 can stop in a short distance if needed?
