Checking the AIP, Plymouth's instrument approach runway is 13/31 which is quite a bit longer (TODA 1168m for instance).

Tu154lover - I was being ironical of course! I actually find this thread quite entertaining! As has been mentioned, there is a lot above and beyond the runway length that needs to be considered (QNH, temperature, derate if applicable, slope, wind, weight, etc). So what might look OK on a given day might not be feasible the next due to weather conditions etc. It wouldn't be a good commercial proposition for an operator to fly with some seats blocked when the conditions on the day would actually have allowed them to be filled, or conversely to sell seats only to realise on the day that some PAX or bags (or both) have to be offloaded due performance. Catch-22...
Cheers
