Other Changes

Changes to the 757-300 were made to accommodate the extended fuselage and increased passenger and cargo load.

• The maximum takeoff weight was increased to 272,500 pounds (123,600 kg) to preserve the passenger/cargo load capability.
• The aircraft's wing, landing gear and portions of its fuselage have been strengthened and new wheels, tires and brakes added to handle the extra weight.
• The environmental control system for the passenger cabin has been modified to accommodate the additional passengers. A larger precooler, more powerful fans and an additional temperature zone have been added.

Because the airplane is longer, Boeing made several modifications to protect against possible damage from tail strikes during takeoffs and landings. A retractable tail skid similar to that on the 777-300 was added. It has a body-contact indicator that lets the pilot know if the body of the airplane has made contact with the ground, despite the tail skid.
