Anyone know what this knob does?

[Vilvens24]

1968 G, I thought it was for a LoPresti Boom Beam, but I don’t see any reference to it in the stc install or stc guide.

And the element in the bulb seems to be burn out so I have no way of checking.

 

Thanks

Interesting knob.  Take a look at the bottom of this page.  Looks like a Knots2U Mod but I have no idea what it does.

Thank you sir, looks like it turns my G into a disco ball.

That looks like a Max Pulse light control for your landing light. It’s selectable for pulse rate.

It’s a max pulse light controller, however I’ve never seen such a nice placard on the panel, the Maxpulse comes with a cheesey black card that goes under the switch.

AC Spruce shows the cheesy card well, I’d like to know how the placard was done on your airplane. does anyone know?

looks like a custom instrument panel with screen printing.  Nice!

For all the fancy disco options...

• X = Both Circuits Off
• S = Starboard (right) on only
• P = Port (left) on only
• S+P = Both circuits on
• A44 = Alternate 44 PPM
• B44 = Both Flash 44 PPM
• A88 = Alternate 88 PPM
• A120 = Alternate 120 PPM

The funky thing about that landing light  controller is that if you have A single circuit i.e. landing light and no taxi light It doesn't do anything on "S" starboard position. Don't why they did not a make a single light option or have a jumper for the taxi "S" position so the light is on when that position is selected.

If a company can use one part, without any changes to it, for multiple jobs, it is a big money saver.  20 or so years ago, a study at Ford showed that just by eliminating a part number from their inventory would save the company $1,000,000 per year.

That's the forward static system drain.   There's a rearward one on the same side near the trailing edge of the wing.

I believe the front drain is the pitot drain.

Yeah, that.   Air plumbing stuff.

It's so you can light up your turn when on the taxi way! /end sarcasm/attempt at being funny

Having both on would be much more helpful!

Upon further review, that knob does about 6 different strobe light patterns.

 

Wayyyyyyy overkill, but it came like that.

As far as the false economics of minimum part numbers goes...

GM changed the design of their ignition switch... and left the part number the same...

Somebody got called out for hiding the evidence... the original design was proven to kill people when the keys fell out...

The new design stopped the killing... but didn’t change anything for the old owners...

 

Use caution when trying to save money on this tiny scale...

Somebody invented the internet, and the cloud... to save so much money these bad decisions don’t need to be made any longer...
