FS2004/FSX Captain Sim Boeing 757-200 Payload Mod. Ever since the Captain Sim B757 came out the users who fly it have been using the ACE tool included to load their aircraft. Captain Sim defined the position of every seat on board the 757. This meant the user had a hyper realistic payload. On the downside however it was practically impossible to alter the payload without using ACE. So if the user wanted to fly more than one leg on a flight they had to use the same payload, or switch to a default aircraft, run ACE to reload the 757, then reload the 757 where about they had to reset all the systems in the aircraft. Combine that with the fact the you are limited to 172 passengers. Which is small for a 757, and you had to use ULD's for your cargo. Un-realistic since the real 757 loads bulk cargo. Only the freighters use ULD's. This mod was created to rectify that. After installation you will no longer need to run ACE to edit the payload of the aircraft. you will also have a higher passenger count (up to 184 pax) and will be able to load bulk cargo instead of ULD's.
