Strange Problem

Recommended Posts

I was climbing 20,000 FT . I realized DC-6  VC cockpit  screen started slowly became dim. Then couple second after all screen was dark. I switched the view to outside momentarily  screen  turns normal then completely went dark again.

No  dark incident  happened with  747-400.I completed  KEWR-KSEA long flight with out any problem.

What is happening with DC-6 ? Will you please advise how to solve the problem.

Thanks

If this was the X-Plane version, you passed out (virtually) from lack of oxygen. In other words, you either forgot to set up your pressurization, or something failed in the pressurization system.

Gray-out/Black-out is a stock feature of XP itself if you climb above 14,000 feet in an unpressurized aircraft.

The same goes for the P3D/FSX version.

In the case of XP hypoxia effects are a core feature of the sim. Apparently in the MSFS version, PMDG took a cue from X-Plane and coded the effect into the aircraft itself.

Jim.

Thank you, that is interesting.

 Pressurization was setup before  the take-off by AFE.

I will make a test flight .

I made a test flight. Before take-off AFE verified Pressurizing  "Set" but he didn't. I set the pressurizing  and reached 20,000ft with out incident.

Yep, just had the same problem.  Easy enough, if you know to check for it!

You as a pilot are responsible to set the correct pressurization altitude on the press panel. The AFE does not know in which FL you intend to fly.

What AFE checks is that the press panel is in the correct config .

There's no way that he can know what level you intend to fly, so the response of 'set' by him is simply a read through of the checklist, assuming you've set it. At 'normal' DC-6 cruising levels, you could theoretically leave it at 0 and be fine. If you have terrain to clear, or MEAs/MOCAs/etc to follow, then you need to remind yourself to set it.

Best practice? Ensure you have oxygen to breathe by setting your pressurization for each flight.

I'm surprised by how many people are getting caught out by this one.

I'm not, but then, I still remember all the complaints Henning got about the torque meters not working in the Aeroworx King Air. The problem was that they didn't switch on the inverters. (That gripe even ended up in the AVSIM review of the plane!)

Wow.  A blacking-out feature!  Now that certainly fits the criteria of "as real as it gets"...

No kidding - when I saw the fading I thought, no way did they model hypoxia, but sure enough - they did!  Obviously the remedy is to descend or turn on oxygen, but since autopilot is on and you can't see anything to change the autopilot, that is a difficult task!  If you leave the F9 button pushed on you get a glimpse of the cockpit and can toggle between F9 and scrolling around the view until you can see what you need to push.  Leave F9 pushed in and you should be able to move controls a little bit to begin a descent.  I got down lower and sure enough the cockpit went normal again.  Obviously this isn't how real hypoxia works - once you're out you're out, but hey, I didn't feel like exiting the sim and starting again!!
