Aircraft instrument panel with engine controls and indicators of a Cessna 182D Skylane. Aircraft engine controls provide a means for the pilot to control and monitor the operation of the aircraft's powerplant. This article describes controls used with a basic internal-combustion engine driving a propeller. Some optional or more advanced ...
The battery pack holds 13.5-kWh. Empty weight is 488 kg (1,076 lb) and hosts an up to 79 kg (174 lb) pilot. The vehicle features at least three flight controllers, driving 32 vertical propellers in the case of motor or flight controller failure, with a parachute in the event of total failure.
Among the designs he tried was the Oehmichen No. 2, which employed four two-blade rotors and eight propellers, all driven by a single engine. The angle of the rotor blades could be varied by warping. Five of the propellers, spinning in the horizontal plane, stabilized the machine laterally. Another propeller was mounted at the nose for steering.
The pilot manually fine tunes the engine r.p.m. so as to stop disk rotation, thereby synchronizing the propellers. This is a useful backup to synchronizing engine r.p.m. using the audible propeller beat. This gauge is also found installed with most propeller synchronizer and synchrophase systems.
A full authority digital engine (or electronics) control (FADEC) is a system consisting of a digital computer, called an "electronic engine controller" (EEC) or "engine control unit" (ECU), and its related accessories that control all aspects of aircraft engine performance.
The Phantom 4 Pro+, offered alongside the Pro, features a controller with a 5.5-inch screen and an integrated flight app, allowing it to be flown without a separate mobile device. [38] [41] The Pro uses Model 9450S propellers and is powered by a 5870mAh battery, giving it a fight time of approximately 30 minutes.
A valve-regulated lead-acid battery is a battery type that is popular in telecommunications network environments as a reliable backup power source. VRLA batteries are used in the outside plant at locations such as Controlled Environmental Vaults (CEVs), Electronic Equipment Enclosures (EEEs), and huts, and in uncontrolled structures such as ...
In a multi-engine aircraft, if one engine fails, it can be feathered to reduce drag so that the aircraft can continue flying using the other engine(s). In a single-engine aircraft, if the engine fails, feathering the propeller will reduce drag and increase glide distance, providing the pilot with more options for the location of a forced landing.
