A runway arrangement comprising: a first runway section (202-1) designated as a landing runway section; a second runway section (202-2) designated as a take-off runway section; and a sterile safety area (210); wherein the first and second runway sections are linked by the sterile safety area (210); the runway arrangement comprising a missed approach point for aircraft due to land on the first runway section, displaced from the start of the second runway section (202-2) by a distance greater than H/tan θ.sub.1; where H is a safe turning height and θ.sub.1 is an angle of ascent following a missed approach; wherein H is greater than 150 m and θ.sub.1 is greater than 2°.

There is provided an elevated light fixture that includes a frangible coupling designed to secure the fixture to the ground, a housing designed to be affixed to the frangible coupling and house and/or support additional features of the light fixture, a cap to lock the globe atop the housing by engaging a component of the housing or a support component that is affixed to the housing, lighting components designed to emit light such as an LED as well as a lens designed to sit atop the housing when assembled that is transparent or translucent to allow light from the lighting components to pass through, electronic components designed to deliver electricity to the lighting components such as a circuit card and a power cord, and support components that support the lighting and/or electrical components such as a parts retainer flange.

The present invention provides an attachment device for an aircraft landing guidance flashing light and an aircraft landing guidance flashing device that do not require adjustment of the angle of the flashing light at the time of attaching an aircraft landing guidance flashing light to the attachment device for an aircraft landing guidance flashing light. An attachment device for an aircraft landing guidance flashing light includes a pair of attachment arms 11; and a light emitting portion fixing plate 12. The light emitting portion fixing plate 12 detachably fixes an aircraft landing guidance flashing light. The light emitting portion fixing plate 12 is supported by the pair of attachment arms 11 such that an angle of the aircraft landing guidance flashing light is at a predetermined angle in a state where the aircraft landing guidance flashing light is fixed to the light emitting portion fixing plate.

Methods, devices, and systems for airfield luminaire vibration monitoring are described herein. In some examples, one or more embodiments include a computing device comprising a memory and a processor to execute instructions stored in the memory to receive a vibration signal from a sensor on an airfield luminaire, compare the vibration signal from the sensor to a vibration profile for the airfield luminaire, and determine a status of a bolt of the airfield luminaire based on the comparison.

The present invention provides a lamp capable of preventing an increase in weight and dissipating heat of the LED module. The lamp of the present invention includes an LED module 11 serving as a light source, a heat transfer unit 12, a light distribution unit, a casing 14 including an opening, and a light transmissive cover 15. The LED module 11 includes plural LEDs and an LED substrate having an LED-mounting surface on which the plural LEDs are mounted. The light distribution unit is disposed on a light emitting side of the LED module 11. The LED module 11 and the light distribution unit are disposed in the casing 14. The light transmissive cover 15 is disposed over the opening of the casing 14. The LED module 11 is disposed in the casing 14 to be distanced from the casing 14. The heat transfer unit 12 is disposed such that heat of the LED module 11 can be dissipated into the casing 14.
