Isle of Man 08/26 - 1754 metres. Bristol 09/27 - 2011 metres. Could be interesting to see a 319 depart IOM on a full load with that length of runway. Not much room for error.
1754 + about 245m extension
(i'll try and double check)
edit: i found the following of interest. indicate "Starter Extension 150m x 30m"
