From the information you gave us earlier you should have already experienced ATR's or A319's at Southend. Also the DASH 8s Flybe use each summer for their Jersey rotation?
The Aircraft size using Southend will not be any different from now. The main difference is they will be carrying passengers and small freight. The frequency of commercial aircraft will be more, but even IF/when it achieves its goals of 2m passengers by 2020. Thats still only 10% of the passengers moved by Stansted in 2009 and a third of the movements.
