The Finnish company's PC-based solution provides fully-automated
runway visual range assessment and reporting.
The
runway visual range system is used by air traffic controllers to provide information to pilots on runway visibility in order to secure safer landings.
The FAA helps us confuse
runway visual range (RVR) with flight visibility, but they're different concepts.
The CAT II MET equipment includes sensors to measure variables essential to aviation safety wind, pressure, humidity and temperature, visibility,
runway visual range (RVR), a rain gauge to measure precipitation levels, and a ceilometer to measure cloud base.
While flying an ILS approach, the pilot of a Lancair LC41 (the basis of today's Cessna Corvalis) was advised by the tower controller that the
runway visual range (RVR) was 600 feet.
At India's busiest airport, the Indira Gandhi International Airport in New Delhi, no flight could take off between 12 midnight and 10 am on Saturday after the
Runway Visual Range failed.
The airlines claim that the airport has yet to complete testing for Category II landings that allow aircraft to land with a
runway visual range of 350 metres, Reuters reported.
A pilot from Virginia asked whether a pilot may operate an aircraft below a published DH/DA or MDA if the pilot has the runway in sight but the
runway visual range or RVR is reported at less than the published RVR for the approach.
During the approach,
runway visual range was reported to the pilot as varying between 800 feet and 1200 feet.
The second was RNAV-authorized, but the touchdown
Runway Visual Range on Runway 36 was below his company RNAV minimums.
Runway 27 would be upgraded to CATIIIB, to provide a precision instrument approach and autopilot landing with no decision height or
runway visual range limitations (assuming the landing aircraft and its crew are suitably equipped).
