As we speak,
in order to meet the steep approach AND the go around gradient, The Falcon 2000 EX has to approach with Airbrake 1 and Vref+10 mini, as a consequence the Landing distance has to be factored +12%. Conversely the field length landing weight occurs when available runway length multiplied by 0.89 is equal to the landing distance ( or Landing field lenght as applicable) given by the tables.
This is why for the time being you cannot land with a F2TH in LCY
