4 × JT3D turbofan · three-crew with a flight engineer · EPR thrust
Every phase for the Boeing 707, as flown in a flight simulator — panel scans marked as flows, read-and-respond cards marked as checklists. Open the interactive version to tick lines off, fill in your speeds and keep your place between sessions.
-120 — The first production build, short body. JT3C turbojets on the earliest airframes.
-320B — The intercontinental one with the extended wing and JT3D fans. The definitive 707.
-320C — Convertible passenger and freight, with a main deck cargo door.
E-3 / KC-135 family — Military relatives on the same airframe. Related, but their systems and these items diverge quickly.
Four mains, two reserves and a centre tank on most builds, all balanced by hand. The engineer flies the fuel while the pilots fly the aeroplane.

A freighter's CG range is wider than the passenger version's and the load is not self-loading. Check the trim setting against the load sheet, not against habit.

ENGINE 3 STARTENGAGED
Number 3 first is common, since it drives the hydraulics most operators want running early. Sequences vary — follow your add-on's checklist.
