instrument approach

A landing approach made without visual reference to the ground by the use of aircraft instruments and ground-based electronic or communications systems or devices. An aircraft making such an approach should be flying in accordance with an IFR (instrument flight rules) flight plan. An approach carried out with the help of systems such as ILS (instrument landing system), MLS (microwave landing system), GCA (ground-controlled approach), VOR (very high frequency omnidirectional radio-range), TACAN (tactical air navigation), LOC (localizer), and GPS (global positioning system) would be categorized as an instrument approach. See ground-control approach.

Although an airport with no instrument approach whatsoever is an acceptable filed alternate if VFR from the MEA to the ground, according to a 2006 interpretation to Barry Lloyd, "Alternate NA" means the airport cannot be used as a filed alternate even in severe-clear weather.

Let's examine the affects of the MH-60R's known BARALT error on the ability of a pilot to visually acquire the runway approach lighting when conducting a precision instrument approach to one of the Navy's busiest airports: the precision approach radar (PAR) to runway 36 at Naval Air Station North Island (KNZY).
Russia and Poland have repeatedly disagreed on the precise causes of the incident, with Poland claiming Russian air traffic controllers were partly to blame, while Russia said the fault lay purely with the crew's failure to fly a correct instrument approach.
