They depressurised before they went on Oxy?
Where did they get that from?
From the B200 QRH: Cracked or shattered windscreen.
Preface:The following procedure should be used when one or more cracks occur in the inner or outer ply windshield. The procedure is also applicable if the windshield shatters. This usually occurs in the inner ply and is characterised by a multitude of cracks which will likely obstruct the crew members vision and may produce small particles or flakes of glass that can break free of the windshield.
1. Altitude maintain 25,000 FT or less, if possible!
2. (a)Pressurisation Controller reset. Suggested pressure diff 2.0-4.6 (4.6 will supply 10,500 FT cabin at 25,000FT)
(b)Before Landing Depressurise cabin prior to touch down.
Two questions, why not follow the approved procedure? Secondly was it only one window which cracked or both? If it was undamaged why not let the First Officer fly?
Surely the first action in any aircraft where the integrity of the aircraft hull is at stake, would be to don your oxy mask, not disconnect the autopilot and depressurise the cabin......
PS: My bolding.
