Default Remote tire pressure monitor

Has anyone found a remote tire pressure monitoring system with sensors that will work on our tires? Most senders appear to be quite large and I'm not sure that they will fit inside the wheel fairings.

It would really be nice to be able to see actual tire pressures rather than guessing if the tire looks low enough to have to check, which is always a pita.

Would something like this work for you? https://www.amazon.com/dp/B074WKVG6J...e-798520fb1ea5

That's really interesting. I can leave the receiver on the wall in the hangar and glance at it during pre-flight...

Is anyone using these? Do they work well? How heavy are the sensors, do they fit in the wheelpants?

Default My experience with a monitor

I thought that would be a great idea. I ordered and installed a similar unit on my car first to try it out.

First I was concerned by the large cap size for our restricted area and the fact that they are always pressurized so if damaged somehow you lost all your air.

Turned out that they don't turn on until the car gets over 20 mph for a minute or two which was not what I wanted. I wanted instant reading to be part of pre-flight.

For me desired would be small caps with a leak failsafe and a remote reading stationary, say a handheld display that you can turn on and will read air pressure as part of pre-flight

Looking at Amazon, there are plenty of examples. However, I am wondering exactly how they work.

The valve is normally pressured closed so there would be no pressure to read at the cap. It seems to me that these devices must somehow depress the valve stem so that they are pressurized. That means you are relying on the seal around the cap and the valve stem to stop the tyre going flat.

Or am I missing something....?

Default Judging tire pressure on preflight

Over 20 years I've learned I can KINDA judge tire pressure by the size of the tire's contact patch on the hangar floor.

And I've wondered if it would be practical to make a go/no-go gauge that would slip under the pant like a chock and let you know if the tire was getting deflated enough to require airing up. Seems like the thickness could be calibrated against known pressures, and slid under the pant on a selfie-stick type of telescoping wand so you wouldn't have to get on the ol' knees.

Maybe "A couple printed ideas" could make a set for Amanda to sell

I'd do mine on a table saw with rip fence, I guess.

Exactly correct. Make up a couple of PVC ĎUí shape chocks and get them to just slide in when the tires are at pressure. If a tire is even a little low the chock will not slide in. As a side benefit you get a set of lightweight chocks.

At tire change you may need to adjust to the new tire.

Simple, cheap, easy.

Fuel load?
Baggage load?

Makes little difference. Consider this as a ďgo/no goĒ check.

Iím looking to switch to nitrogen, but havenít found an aviation source near me yet. Probably need an FBO that services Jets. There are a good number of higher end car dealerships that provide the service, but Iím not pulling my tires off.

Nitrogen is a bit better, more stable in varying temps IMO.
