Watercraft navigation lights must permit other vessels to determine the type and relative angle of a vessel, and thus decide if there is a danger of collision. In general, sailing vessels are required to carry a green light that shines from dead ahead to 2 points (22 + 1 ⁄ 2 °) abaft [note 1] the beam on the starboard side (the right side from the perspective of someone on board facing ...
Light level 5.0 μW/cm 2; for example, a legal 5 mW laser pointer at 1,200 feet (370 m). Simulation of temporary flash blindness where the image takes from a few seconds to a few minutes to fade away, depending on how much light entered the eye. Light level 50 μW/cm 2; for example, a legal 5 mW laser pointer at 350 feet (110 m).
Air traffic control signal light gun in use at base flight tower. In the case of a radio failure or aircraft not equipped with a radio, or in the case of a deaf pilot, air traffic control may use a signal lamp (called a "signal light gun" or "light gun" by the FAA [1] [2]) to direct the aircraft.
Each light is designed so that it appears as either white or red, depending on the angle at which it is viewed. When the pilot is approaching the lights at the proper angle, meaning the pilot is on the glide slope, the first set of lights appears white and the second set appears red. When both sets appear white, the aircraft is too high, and ...
A spike of reported incidents in 2015 prompted a FAA study into its causes, which found the increase was due in equal parts to more laser strikes and more reports from pilots, according to an FAA ...
An ADB Safegate A-VDGS installed on Stand K3L at Mumbai Airport.. A stand guidance system is a system which gives information to a pilot attempting to park an aircraft at an airport stand, usually via visual methods, leading to the term Visual Docking Guidance System (VDGS) and also A-VDGS (the A standing for advanced) This allows them to remain clear of obstructions and ensures that jetways ...
