The distance "d i" is the sum of the measured limit line setback distance—which is typically regulated by a Manual on Uniform Traffic Control Devices, at often between 4 and 30 feet in the United States [134] [135] [136] —and the crosswalk, parking lane, and road shoulder width.
Radar separation is applied by a controller observing that the radar returns from the two aircraft are a certain minimum horizontal distance away from each other, as observed on a suitably calibrated radar system. The actual distance used varies: 5NM (9.26km) is common in en route airspace, 3 NM is common in terminal airspace at lower levels.
Near major airports, the intersection designation code typically consists of three letters followed by the runway number. Most other intersection designations consist of five-letter combinations that are either pronounceable or chosen for their mnemonic value, since either air traffic control or the flight plan may require the pilot to announce ...
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 ...
The National Association of City Transportation Officials recommends daylighting by preventing cars from parking within 20–25 feet (6.1–7.6 m) of an intersection. [8] If parking is merely disallowed by law or signage, drivers may not always comply, so it is best to replace parking with curb extensions or other physical infrastructure that ...
Around 4:30 p.m. Friday, air traffic controllers directed a chartered flight that had just arrived from Spokane, Wash., to hold short of crossing a runway where a second plane was departing ...
There are some secret areas on widebody aircraft where pilots and cabin crew go to rest during long flights. Passengers can’t access them under any circumstance.
Under visual meteorological conditions, the minimum visual range, distance from clouds, or cloud clearance requirements to be maintained above ground vary by jurisdiction, and may also vary according to the airspace in which the aircraft is operating. [4] In some countries, VFR flight is permitted at night, and is known as night VFR.
