    Fast jets are more constrained and at a typical low-flying speed of 450 knots (830 km/h), 200 feet (61 m) is not unusual and 50 feet (15 m) is possible in relatively flat terrain. Power wires are a danger to all aircraft flying at low level and "wire strikes" are common, such as the 1998 Cavalese cable car crash. [5]

    The inverted fly (also known as a bent-over lateral raise, reverse fly, or rear delt fly) works the posterior deltoid. This movement is the opposite of a chest fly. The exercise is performed with the torso parallel to the ground, facing down, with the hands in front of the face.

    Map of Trentino, Italy; Cavalese is located in the north-east of the autonomous province. On 3 February 1998, an EA-6B Prowler, BuNo (bureau number) 163045, 'CY-02', callsign Easy 01, an electronic warfare aircraft belonging to Marine Tactical Electronic Warfare Squadron 2 (VMAQ-2) of the United States Marine Corps, was on a low-altitude training mission.

    The upright row is one exercise that can be performed on the cable machine. A cable machine is an item of equipment used in weight training or functional training.It consists of a rectangular, vertically oriented steel frame about 3 metres wide and 2 metres high, with a weight stack attached via a cable and pulley system to one or more handles.

    NATO tactical ultra-low-level flight training in Canada is located at CFB Goose Bay in Labrador.In response to lessons learned from the Vietnam War and the growing sophistication of Soviet anti-aircraft radar and surface-to-air missile technology being deployed in Europe, NATO allies began looking at new doctrines in the 1970s–1980s which mandated low-level flight to evade detection.

    The pilot can then fly just above the runway while the aircraft accelerates in ground effect until a safe climb speed is reached. [2] For rotorcraft, ground effect results in less drag on the rotor during hovering close to the ground. At high weights this sometimes allows the rotorcraft to lift off while stationary in ground effect but does not ...

  8. Flyback converter - Wikipedia

    en.wikipedia.org/wiki/Flyback_converter

    Fig. 1: Schematic of a flyback converter. The flyback converter is used in both AC/DC, and DC/DC conversion with galvanic isolation between the input and any outputs. The flyback converter is a buck-boost converter with the inductor split to form a transformer, so that the voltage ratios are multiplied with an additional advantage of isolation.

  9. High-voltage cable - Wikipedia

    en.wikipedia.org/wiki/High-voltage_cable

    High voltage is defined as any voltage over 1000 volts. [3] Those of 2 to 33 kV are usually called medium voltage cables, those over 50 kV high voltage cables.. Modern HV cables have a simple design consisting of a few parts: the conductor, the conductor shield, the insulation, the insulation shield, the metallic shield, and the jacket.
