The AN/MPN-14K Mobile Ground Approach System can be configured as a complete Radar Approach Control (RAPCON) or Ground Controlled Approach (GCA) facility.
The radar unit is used by air traffic controllers to identify, sequence, and separate participating aircraft, provide final approach guidance through air defense corridors and zones, and coordinate ID and intent with local air defense units at assigned airports and air bases. These services can be provided in all types of weather.
The radar unit is capable of identifying aircraft using secondary radar up to a 200-nautical-mile (370 km) radius and primary radar coverage to 60 nautical miles (110 km). The PAR provides both azimuth and elevation information from 15 NM to touchdown. Both the PAR and ASR can be used as final approach aids. The unit has three ASR display indicators and one PAR indicator located in the operations shelter, and one each ASR and PAR indicator located in the maintenance shelter. Complete operations are conducted from the operations trailer. The system is limited to a single runway but has the capability of providing opposite direction runway operations with the aid of a transportable turntable.

“From three to six months, most babies have settled down enough to be fun but aren’t mobile enough to be getting into trouble. This is the time to pay some attention to your relationship again. Otherwise, you may spend the entire postpartum year thinking you married the wrong person and overlooking the obvious—that parenthood can create rough spots even in the smoothest marriage.”
—Anne Cassidy (20th century)
“The future is just as much a condition of the present as is the past. “What shall be and must be is the ground of that which is.””
—Friedrich Nietzsche (1844–1900)
“... the ordinary is simply the universal observed from the surface, that the direct approach to reality is not without, but within. Touch life anywhere ... and you will touch universality wherever you touch the earth.”
—Ellen Glasgow (1873–1945)
“In a universe that is all gradations of matter, from gross to fine to finer, so that we end up with everything we are composed of in a lattice, a grid, a mesh, a mist, where particles or movements so small we cannot observe them are held in a strict and accurate web, that is nevertheless nonexistent to the eyes we use for ordinary living—in this system of fine and finer, where then is the substance of a thought?”
—Doris Lessing (b. 1919)
