In paragraph ii, the seventh sentence (beginning 'The economic reality...') refers to the airport as a constraint. The constraint is not the airport as a whole, but the existing runway length, for two particular reasons:
• Older regional aircraft (like the BAe 146 and Avro RJ series which were specifically designed for short take off and landing) are being replaced by newer regional aircraft types (such as the Embraer 195 and the Bombardier C series) which use less fuel and are less noisy even though they are larger, but they require a longer distance to reach take off speed
• The existing landing distance for the 24 runway direction is 1399 metres while for the 06 direction it is only 1279 metres (less than London City Airport). Airline operations must assume the shorter of these two which restricts the loads that aircraft can carry when using Southend Airport.

In paragraph iii the reference to Boeing 737s may confuse as not all models of the 737 would be able to operate with economic loads from a 1799m runway. It would be better to refer to aircraft with a seating capacity of generally between 100 and 149 seats, such as the Airbus A319, smaller 737 types and the range of new aircraft by Embraer and Bombardier (C series), particularly designed for European services. There is also a reference to attracting two or three fixed base operators. As FBOs are usually related to business or general aviation operations it would be better to refer to two or three airlines which would base aircraft at the airport.
