Blackout Bug: Boeing 737 cockpit screens go blank if pilots land on specific runways
https://www.theregister.co.uk/2020/0...een_blank_bug/
Seven runways, of which five are in the US, and two in South America - in Colombia and Guyana respectively – trigger the bug. Instrument approach procedures guide pilots to safe landings in all weather conditions regardless of visibility."All six display units (DUs) blanked with a selected instrument approach to a runway with a 270-degree true heading, and all six DUs stayed blank until a different runway was selected," noted the
FAA's airworthiness directive, summarising three incidents that occurred on scheduled 737 flights to Barrow, Alaska, in 2019.

This AD requires revising the airplane flight manual (AFM) to prohibit selection of certain runways for airplanes equipped with certain software. This AD was prompted by reports of display electronic unit (DEU) software errors on airplanes with a selected instrument approach to a specific runway. The FAA is issuing this AD to address the unsafe condition on these products.
