Aero Mad:
Isle of Man (08/26 runway is 1754m long). easyJet operates the Isle of Man - Liverpool route which takes roughly 50 minutes with an A319
Actually the IoM runway 08/26 is 1837m long, but it has a TODA of 2815m on 08 and 2057m on 26.
They also operate Liverpool - Jersey (09/27 runway is 1706m long) with A319s
But Jersey TODA is 1889m on rwy 09 and 2469m on 27.
Phileas Fogg: Gib runway is 1829m with civil TODAs of 2518m in both directions (source: UK Mil AIP)
Expressflight:
Physically SEN's TODA will be greater than 1,799m but that is the limit set by the CAA for a Code 3C runway so 1,799m is what must go into the RTOW calculation
As I understand it Southend's TODA is limited by the Runway End Safety Areas, not by some arbitrary limit placed on it because it has to remain a Code 3C. And since the recommended RESAs for Code 3 are the same as Code 4 it would make no difference to the declared distances if they went for Code 4. But in any case, whatever the reasons, the planning application for the Southend runway extension gives the following declared distances for the extended runway:
06 24
TODA 1739 1739
TORA 1799 1799
LDA 1604 1604
ASDA 1658 1739
Now, you'll probably spot that having TORA>TODA looks a bit odd, so it's my guess they got those transposed when compiling the Environmental Statement. But the upshot is, extended Southend's TODA in both directions will be less than IoM, Jersey, Gib etc. Its LDA of 1604m will be similar to IoM and Jersey but 75m longer than Gibraltar. But LDA is usually less critical because you can plan to land with little fuel, especially if the alternates are close at hand.
