Software bugs can present in incredibly strange ways and today we bring you one that could be rather dangerous.

The bug involves Boeing’s 737 Next Generation airliners. The bug sees the six displays go blank should a pilot dare attempt to land in a westerly direction at seven airports.

The bug appears to affect Boeing 737-600, 737-700, 737-700C, 737-800, 737-900 and 737-900ER models running Common Display System Block Point 15 (CDS BP15) and FMC U12 or later.

In an airworthiness directive issued by the Federal Aviation Administration in the US, it was noted that three incidents where the display electronic unit (DEU) on Boeing 737 NG airplanes blanked.

The incident is believed to have been caused by the latitudinal and longitudinal values of runways in the US, Colombia and Guyana.

The displays would remain blank until a different runway was selected.

The seven airports that would prompt this bug to present.

The good news is that according to a report by The Register, the faulty DEU software has been removed from affected airliners that have landed and conducted scheduled airline service at the affected airport in the US.

Boeing has had a rough time of late with its 737 Max airliners being grounded last year.

Just this week a 737-800 operated by Ukraine International Airlines crashed outside of Tehran, Iran killing all 176 passengers. This is the third deadly crash involving a Boeing airliner since late 2018 according to Fortune.

“This is a tragic event and our heartfelt thoughts are with the crew, passengers, and their families. We are in contact with our airline customer and stand by them in this difficult time. We are ready to assist in any way needed,” Boeing said in a statement.
