Magnetic interference found at London City
Magnetic interference was responsible for “significant navigation problems” a NetJets Hawker 800XP experienced on takeoff from London City Airport (LCY) 15

Magnetic interference was responsible for “significant navigation problems” a NetJets Hawker 800XP experienced on takeoff from London City Airport (LCY) 15 months ago, according to a UK AAIB report released last month.

On Oct. 31, 2006, the fractional airplane was holding at Mike for a departure from Runway 28 on an empty positioning flight from London City Airport to Brussels when the crew saw that the attitude and heading reference system (AHRS) and the heading on both primary flight displays (PFDs) were giving a red flag indication. The pilots considered this a “known fault” at LCY (thought to be attributable to metal in the taxiway pilings). When the airplane was lined up for departure, the red flags disappeared without any further action on the part of the crew.
