Hand starting of aircraft piston engines by swinging the propeller is the oldest and simplest method, the absence of any onboard starting system giving an appreciable weight saving. Positioning of the propeller relative to the crankshaft is arranged such that the engine pistons pass through top dead centre during the swinging stroke.
Starting a Lazair II ultralight aircraft's JPX PUL 425 engine, equipped with a recoil starter. A rope start device housed in a Nose bullet of a Junkers Jumo 004 turbojet.. Rope start (also called ripcord [citation needed], pull start [citation needed], or rewind start [citation needed]) is a method of starting an internal combustion engine, usually on small machines, such as lawn mowers ...

Through the turboprop's tiny window, I see five pristine 4x4’s looming large next to the dusty airstrip. My five traveling companions—Philippe Steyer, the president of INEOS Automotive South ...
A direct start system as used on a marine slow-speed diesel is required to have up to 12 starts on a non-reversing engine or 6 starts on a reversible, or geared, engine. When starting the engine, compressed air is admitted to whichever cylinder has a piston just over top dead center, forcing it downward. [2]

summary plan for direct download into an onboard flight management system; detailed plan for use by pilots; The basic purpose of a flight planning system is to calculate how much trip fuel is needed in the air navigation process by an aircraft when flying from an origin airport to a destination airport. Aircraft must also carry some reserve ...
Decelerating from M3 required a reduction of thrust which could unstart an intake with the reduced engine airflow. The SR-71 descent procedure used bypass flows to give unstart margin as the engine flow was reduced. Thrust reduction on the XB-70 was achieved by keeping the engine flow stable at 100% rpm even with idle selected with the throttle.
