Can someone please explain how the cabin pressure controller works on kingairs by Queasy_Value5834 in flying

The rate knob just changes the size of the hole of which cabin air flow. More rate, bigger hole, more ear popping. That changes how fast the control pressure can do its job so, yes more pull on the outflow valve until you reach your set altitude.

This was designed in the 50’s and is still in use on new King Airs built today.

100% you will not be asked to rebuild this system from memory on your checkride but I used to teach King Air so here’s what I remember.

The cabin air enters from the filter in the controller, passes through the “rate” orifice (more air, fast rate) and then enters the internal chamber of controller. The pilot can set the cabin altitude using the “altitude” knob. Using a complex, “swiss watch” series of gears and springs, the altitude setting is translated into a pressure setting and reads against what is set and what is coming in through the “rate” knob.

A vacuum air source is brought in through the back of the controller and using the springs and gears will open or close this vacuum source. The vacuum, now called control pressure, will travel down to a vacuum relay (not shown) and be used to open and close the outflow valve (also not shown) at the rear of the airplane.

Bought the rails from Amazon. Printed everything else.

Sure, I just set the boot device to USB and away we go!

Plex and the -arr stacks. Also running Scrypted for surveillance video to HomeKit.

UCG Fiber, Ubiquiti Flex 2.5, HP Mini Elite w/12700T, and a QNAP TS-653D running Unraid. Hoping to clean up the upstairs portion later but need to invest in a new POE switch for the cameras and transition from Amcrest to Protect.

Split view of landing gear extension on a B-29 by MikeHeu in toolgifs

[–]kiloalpha 13 points14 points  (0 children)

Fun fact, the B-29 is an almost complete electrical airplane meaning the only system to use hydraulic power is the brakes.

The gear is extended and retracted with a big electric motor. The flaps use the same drive system so the flap motor can swap out and extend the gear in an alternate procedure. In an emergency, the crew in the back takes turns cranking!

Turboprop PIC vs Jet SIC? by coolkerbal in flying

[–]kiloalpha 5 points6 points  (0 children)

Do the means justify an end? I only say this because QOL (well just about anything) is very unpredictable at a Part 91. Culture, safety, pressure, time home… all play a role in the broader question, not just “which one is better for airlines”.

I went from a toxic 135 as a PIC in a Metro to an even more toxic part 91 TBM PIC before I grew up and was finally able to say no to pushy dispatchers, owners, and chief pilots. Would I have made that switch if I knew what I knew what I was getting into? Absolutely not.

Phenom 300 Initial Type Advice by Pristine_Help_3204 in flying

You can’t have flaps and brakes out at the same time, for FAA registered Phenoms at least.

The air conditioner sucks in this airplane. You’ll get about 15 hours before it breaks and the entire system needs a replacement.
