    en.wikipedia.org/wiki/Aviation_obstruction_lighting

    In certain areas, some aviation regulators mandate the installation, operation, color, and/or status notification of obstruction lighting. For maximum visibility and collision-avoidance, these lighting systems commonly employ one or more high-intensity strobe or LED devices which can be seen by pilots from many miles away from the obstruction.

    The NASA 737 research aircraft on the Wallops runway in 1987 with the microwave landing system equipment in the foreground. The microwave landing system (MLS) is an all-weather, precision radio guidance system intended to be installed at large airports to assist aircraft in landing, including 'blind landings'. [1]

    en.wikipedia.org/wiki/Minimum_en_route_altitude

    The MEA prescribed for a Federal airway or segment, RNAV low or high route, or other direct route applies to the entire width of the airway, segment, or route. MEAs for routes wholly contained within controlled airspace normally provide a buffer above the floor of controlled airspace consisting of at least 300 feet within transition areas and 500 feet within control areas.

  5. Minimum obstacle clearance altitude - Wikipedia

    en.wikipedia.org/wiki/Minimum_obstacle_clearance...

    The MOCA seen on the NACO en route chart, may have been computed by adding the required obstacle clearance (ROC) to the controlling obstacle in the primary area or computed by using a TERPS chart if the controlling obstacle is located in the secondary area. This figure is then rounded to the nearest 100 foot increment, i.e. 2,049 feet becomes ...

  6. Minimum off-route altitude - Wikipedia

    en.wikipedia.org/wiki/Minimum_off-route_altitude

    A minimum off-route altitude (MORA) provides a quick way for an aircraft pilot to read the minimum altitude required for terrain and obstacle clearance. MORAs give at least 1,000 feet altitude clearance above terrain and obstacles such as radio masts, and 2,000 feet where the terrain and obstacles exceed 5,000 feet. [1]

  9. Airport surveillance radar - Wikipedia

    en.wikipedia.org/wiki/Airport_surveillance_radar

    All aircraft are required to carry an automated microwave transceiver called a transponder. The secondary radar is a rotating flat antenna, often mounted on top of the primary radar dish, which transmits a narrow vertical fan-shaped microwave beam on a frequency of 1030 MHz in the L band with peak power of 160 - 1500 W. When it is interrogated ...
