Why no remote unlock?

Totally irrelevant to the original question of how many people could
be packed in a given space around a vehicle.

Most cars are already wired for electrically controlled door locks --
adding a simple radio controlled switch to operate in parallel with
the usual switches is easy. Most GA airplanes do not have the door
locks electrically controlled, as best I know. You're talking
extensive and expensive modifications -- just buy an extra key or two.

What's really needed are fancy wheel covers, and a rear view mirror
where we can hang fuzzy dice

What? You don't have them in yours?

The Government even puts rear view mirrors on fighter planes.

Weight. Every pound you spend on a transmitter/computer, door motors,
mechanisms, entertainment systems, A/C, and/or My Little Pony Stickers
and so forth is another pound of fuel you can't carry, another pound of
person you can't carry, another pound of luggage you can't carry.

With the engine turning? Damn, but that's expensive. I plan to program my
496 at home before I head for the airport, and the GNS430W before engine
start.

There's a rear-view mirror on the Piper Cub I rent, but I think it's
there so the instructor can spy on the student.

Poor implementations, I'm no RFID fan, we're barcode people lol but
there is no reason that a properly designed, keyless remote system
which uses your fingerprint (I would say thumbprint but in your case
) as the "key" to allow the unlocking of the encrypted, transmitted code
can't be accomplished. They are common place (assuming no FAA frequency
issues, blah blah) Encryption is rock solid, unbreakable, it's the
password (in this case your print) that is the weak link.

I use my plane for family transportation. So the wife and kids don't
see a lot of difference between running out to the plane to go to
Mexico vs. going out to the car. So when the family runs out ahead and
we have the car I hit the remote unlock. The other day my wife asked
why the plane doesn't have a remote unlock. When you think about it;
why not have the same ease-of-use items in the plane as the car.

The practical reasons are weight and power draw. Weight is obvious
(and mentioned by others), power draw not so much. The batteries we
use in our airplanes are basically equivalent to lawn tractor
batteries - and not the high end $90 ones that have a 3 year full
replacement and 8 year pro-rated warranty.

The $90 lawn tractor batteries use new technology matted fiber for
suspending the acid, and thus achieve more reserve capacity, more
starting power, and longer life in a smaller, lower weight package
than our aircraft batteries. But we can't use them. Not approved.
What we use is basically the same technology and quality control as
the $25 lawn tractor batteries, but with more paperwork.

Add to this the fact that it is normal rather than rare for an
airplane to sit three weeks without being started. All this time, the
receiver for the locks is powered up and waiting for a signal, drawing
power from a battery that is undersized (for weight) and low tech
(just because) to begin with. Not a good plan.

Michael

The difference is, trying a physical key in a lock is an overt act --
someone is actually trying to gain entry into a specific car. Pressing
a remote device tests all cars in range, in addition to opening your
own specific car. If the first case one can be assumed to be a
deliberate bad guy, in the other, it's an accidental event.
