Not So Bright, Avionics Guys

Over dinner the pilots brief me on the maintenance situation. The oil leak on the right engine turned out (after two o-ring changes) to be the governor leaking. Each time they changed the o-ring, the associated sealant held off the the leak for about ten hours, but now it's fixed, using the governor from the airplane that still hasn't gone to Kansas, because it's now waiting for an on-order governor. (Its papers turned up in someone's briefcase). The CHT is still deferred, as they have apparently determined that the replacement gauge was faulty.

The electronic tachs work well, except -- and my co-worker knew me well enough to preface this with "you're not going to like this" -- the numeric readout does not dim in response to the dimmer switch.

He's right. I don't like it. What is the matter with avionics manufacturers these days? I don't think I've had a newly manufactured avionics item installed in an aircraft that has hooked properly and completely into the dimmer rheostat. In this case the circumference LEDs dim, but the display on the face of the tach doesn't. Add that to the fuel transfer light and much of the specialized mission equipment, and the cockpit looks like a fricking pinball machine when I want it to look like London in the Blitz. And not the parts that were on fire. I need my night vision for finding things like conflicting traffic and airports, and I don't appreciate being half blinded because some equipment designer never considered that someone might fly an airplane in the dark and have better things to look at than their blinking lights.

There's a Canadian Tire in town. I'm going out tomorrow morning to get some of that static cling film you put on your car windshield to declare that you love Siamese cats or brake for shoe sales, and I'm going to cut bits the right size to go over the offending pixels at night.
