So with the understanding that most aircraft security is only good enough to keep honest folks from running off with your airplane...



But does anyone have any ideas on ways to prevent the engine from starting? Other that the big chain prop locks. 



Early on, I was considering second, hidden mag switches.  But I'm wondering if there's an alternative.



Note: I do not have a keyed ignition switch.  Just a toggle switch for each mag and a push button starter switch.

If you have mags, anyone can cut the "P" leads, hand prop the engine and fly away, regardless of anything you've done short of the prop chain idea so long as fuel is available. Maybe a hidden locking fuel valve. Be careful, as this may not prevent the engine starting and there might be just enough residual fuel in the lines to get airborne before the engine quits. The prop chain has the added benefit of being a visible deterrent so they won't even try, but rather go to an easier target.

You may want to check out a product we sell called SmartStart.  It allows for a hidden arming switch that when pressed gives you 1 minute to crank the engine.   It works with the standard start contactor, can interface to a push button switch or standard key switch.    It also listens to interlock switches that must be closed before arming can occur

I have a keyed master, and the starter button won't work without the master. But I guess the aircraft could be hand propped as the mags are both on toggle switches.

Not an option for me as I have a 24v electrical system.

With the understanding that additional layers add complexity and reduce reliability, you could wire your master switch in series with another ubiquitous toggle far from the master, and label it something like "Safety/Normal".



Speaking of extra switches, I had a customer with several planes who put a landing gear switch in his Glasair FT.  Just so he didn't get out of the habit!

Hi Don;

How about a second switch (toggle or rocker) in series with your start button, on the panel or elsewhere, whose function is not called out?

Cheers!   Stu.

PS: I only have a start button, but my canopy locks.

I have a towbar switch that is in series with the starter circuit.  If the towbar is not in place, then the starter will not engage.  When I leave my airplane on the ramp, I do not install the towbar in its holder, thus rendering the start circuit inoperable.
