iRaven, that table states that it is a 'simplified' take-off analysis.
Although it would seem to show that at +5°C, the aircraft could only use the short RW at Cranwell with 54% fuel, it takes no account of surface wind.
Presumably there would be no need to use the short RW unless the crosswind component on the main was out of limits. So it would be interesting to see the take-off and landing performance figures under the same conditions, but with a headwind of, say, 20 kts.
Incidentally, while I admire your optimism regarding 'making it work', I gather that the aircrew outflow rate is now so serious that the shortfall cannot be made up with the current training rate, particularly for FJ pilots...
