Runway visual range expert witnesses may opine on low visibility, visibility problems, prevailing visibility, and related topics. Visibility may have been a contributing factor in Airblue’s flight ED 202 (Airbus A321, AP-BJB) which crashed in Margalla Hills, Islamabad on 28 July 2010 killing all 146 passengers and six crew aboard.
Human error coupled with poor visibility due to low clouds may have been the reasons for the crash. After braking off due to low clouds and low visibility, ED 202 lost visual contact of the runway and the crew may have become disoriented. Air traffic controllers reportedly lost contact with the flight crew during its attempt to land in dense fog and heavy monsoon rain. In this poor visibility the crew may have focused on 7th avenue as runway 12 and approached it for landing.
