pilot side window

[rorythedog]

my passenger would like to know why the little window is not to be opened above 130kts on my m20j and what would happen if it was.

 

anyone know?

Depending on the sense of humor of your passenger....

Answer:

The pilot gets sucked out through that small opening...

Realistically, the vacuum caused by the open window probably effects instruments and other things.

Closing the window with that much vacuum happens with a snap.

Coordinated flight vs slipping could give different results...

-Or-

Nobody knows, because it said don't do it....

Me thinks above 130 knots it might be a bit difficult to close and the additional closing stress could possibly discombobulate the hinges.

 

 Also, if your poodle is setting in the back, it might be a bit too drafty above 130 knots.

 

Not really sure, suggest you to 160 knots, open window, close window and report back to forum.

Actually, it is a little known fact that Al Mooney did a significant amount of aerodynamic testing on the side window position. He determined that above 130 KIAS, his toupee would depart the aircraft.

OK seems I had a table on the subject, like all functions of areodynamics there should be different speed limits for different density altitudes like 100 at sea level 160 at FL12 perhaps it could blow out the back windows.

Test pilot Rich here has opened it at full cruise speed to spit out my gum.

 

The plane and I are still here to talk about it...

For planes with the Brittain altitude hold, opening the window will give you a full down elevator deflection. It's not connected to the static, it just senses cabin pressure

Just don't you hate it when someone gives a logical answer?

It also tends to suck the window seal out into to space. Don't ask me how I know.

[FlyDave]

The aerodynamically induced compressibility caused by the side loading on the forward 4 inches of the window would cause a breakdown of the polymer tensile strength in the longitudinal axis, thereby forcing a complete structural breakdown of the passenger side window followed by an immediate evacuation all matter within the cockpit

OR

I'm full of shit

(Yes, sometimes MooneySpace does produce useless information!)

No, it was a TraveLodge in Iowa City, IA on our way from NY to CA.

We're spending the night in Ogden, UT after 45 minutes in icing conditions at FL180 & FL200 east of here. I'll post about the trip after we get back tomorrow.
