To prevent a flying body from falling out of a parachute device capable of ejecting a flying body and forcibly opening a parachute. A parachute device includes a parachute, a parachute accommodation section configured to accommodate the parachute, at least one flying body including a flying body main body section connected to the parachute, and a gas generating device configured to generate gas, an ejection section configured to eject the flying body, and a lead wire configured to ignite the gas generating device, the flying body main body section engaged with the ejection section, the gas generating device disposed in an internal space defined by the ejection section and the flying body main body section, and the lead wire is led out from the internal space in a different direction from an ejection direction of the flying body in a state with one end connected to the gas generating device.

A precision approach path indicator (PAPI) employs an LED light source with first and second arrays of LEDs or other efficient light sources, disposed one above the other and emitting their respective color lights along an optic axis to a collimating lens of focal length f. First and (optional) second aperture plates positioned along the optic axis, each being a respective frame with a cut-out defining a horizontally elongated aperture for light passing along the optic axis. Intermediate aperture plate(s) can be positioned between the first and second aperture plates. The first frame is positioned between the light source and the collimating lens at the focal distance f from the lens. The optional second aperture plate is positioned at the collimating lens and covers top, bottom, and side edge portions of the lens. A planar blade extends from the light source to the first frame and has a distal edge extending across the aperture of the first aperture plate, substantially at the focus of the collimating lens, dividing the beam into white and red sectors. The intermediate aperture plate(s) can be adjusted for optimal separation. The PAPI can be considered to have an illumination portion formed of the light source(s), blade, and first frame; and an imaging portion formed of an enclosure and a lens positioned at its focal length distant from the front frame aperture and edge of the blade.

This invention discloses an aircraft control method, apparatus and an aircraft. The invention relates to the field of aircraft control technologies. The method includes: obtaining ambient luminance data by a luminance sensing apparatus of an aircraft; determining whether the ambient luminance data satisfies a luminance value required for normal running of a vision system of the aircraft; and adjusting, when the ambient luminance data does not satisfy the luminance value required for normal running of the vision system of the aircraft, a working status of a light emitting apparatus on the aircraft to change light emitting luminance of the light emitting apparatus. The foregoing aircraft control method, apparatus and the aircraft can accurately learn a flight environment in which the aircraft is located, thereby effectively implementing vision positioning on the aircraft and more conveniently controlling the aircraft.
