measuring it on google maps the runway is about 3300m long
from the North, the first exit is about 800m, which would probably involve parking the plane in baggage reclaim
The next exit is 1700m from touchdown, which must be the one RA are using.
If you miss that, it's a further 1600m to the end of the runway, a tight turn, and of course a 1600m trundle back
so 2 miles extra taxiing time, and fuel.
