A "proposecond" is defined as, "the barely measurable time between murmuring "clear prop" and cranking the starter."

For night starts, I've been taught to turn position lights on, strobes off, two one-second pulses of the landing lights, "clear prop," crank. Then don't use strobes or landing lights on the ground until just before taking the runway, lest you ruin your or someone else's night vision.

During the day it's a bit academic because none of the lights will draw attention from anyone who isn't looking straight at them already. Head on a swivel, always be prepared to yank the red knob if you see a kid or a dog running out.

John Bixby - when I mentioned the use of a keyed starter for safety reasons rather than a push button starter, I was meaning in the sense of an unfamiliar or unauthorized person pushing the start button. Think kids at air shows or fly-ins. Not leaving the key in the ignition provides the safety.

There are other things that you can do. In a car I owned before alarm systems were common or inexpensive, I put a switch under the drivers seat. It was the push button type - push (click), switch opens and stays open. Push (click) again and the switch closes and stays closed. It was wired into the power to the fuel pump. Park the car, reach under the seat (through a tiny slit in the carpet) and push the button. Car can't be easily hot wired without knowing about that! Push again when you get back in.

Gripe #2: pilots who yell "clear" while wearing a headset. If someone yells back "There's a dog under the plane (or whatever)". they cannot hear them.
#2b: Pilots who yell "clear" with their headset on, and the master and intercom on too. Blasts away in the ears of the passengers.

I've recently replaced a keyed mag/start switch with guarded toggles. The mag switches use "space shuttle" guards from Perihelion Designs. I can secure these toggles in the "OFF" position by inserting a cable lock through the switch guards.

The starter is covered by a red switch cover guard. It can either be safety wired closed to prevent access to the switch, or I can disable the starter circuit by locking out the starter circuit breaker. This is easy to do with either a purpose-designed CB collar or with an appropriately-sized zip tie.

Having flown with this same arrangement in my other airplane now for eight years I can say that I'm comfortable with having kids in the airplane when the starter lockout is applied.

Each of us will have our own opinion on the topic. It's good they're expressed here so we can learn from insights shared by others.

Nobody said anything about using toggel switches with a positive detent. Be sure what ever switch you pick has a positive detent so your mags can not be inadvertently switched off during flight. Mine you have to pull the toggle switch over the detent to turn on/off. If you bump the switch accidentally during flight it won't open your mag.

Default Secret cutoff switch

I was thinking of wiring a guarded switch, in-line with the starter switch, and locate it inside my locked forward baggage compartment. It would almost always be "On", for normal ops as I intend to keep the plane in a hangar, but if I ever left it outside where someone could reach my starter button, I'd use it to disable the starter.
Thoughts?

In other words, your Starter button is essentially always "hot". Hmmm...

This brings up a good point; depending on how they are wired. Most starter switches (button or key) are hot or not at the same time if wired properly (that being downstream of the master relay, preferably on th main buss)...so neither type should be activated without the master "on" first.

I've built RV's both ways, and each has their pro's / con's....so I won't take sides other than to say you should take into account how they are wired in order to keep them safe (and secure). A "vanity switch" in line does help.

Just my 2 cents as usual!

Cheers,
Stein
