Proposed 737 Cabin Altitude Warning Lights
Just noticed this Boeing Fleet Team Digest 737-FTD-31-06003 which “has been initiated to investigate the potential to improve the warning system through the addition of warning lights to supplement the existing aural warning system.”
It goes on to say that “Design change solution selection (hardware change) is imminent. Additional visual indications in the flight deck are under consideration.”
This is very good news.
