Brief Description: Pitot Tube - 1
|
|
Because this is an IFR jet, it needs a heated pitot tube which is not covered in the manual. So, some head scratching,a few texts with Nick, and a call to Dynon tech support and it all seems pretty straight forward.
Arion puts their controllers in the cabin. Dynon said best to keep it as close to the pitot tube as possible because of wire length and the magnetic field generated by the controller. Nick (Arion) has not had issues with the magnetic field causing radio interference, but radios and wires are different in every plane. Nick and Jason (Arion's A&P mechanic) have done this many times before and have the knowledge to know what works and how to pull it off. I've flown planes with sketchy radios and don't want to risk installation error on my new plane. So, I decided to go with a large pitot tube/controller plate on the underside of the wing just inboard of the aileron bellcrank inspection cover. The controller and pitot tube mounting bracket will be mounted on the inside of this plate. More work, but less risk for me.
Once Dave and I agreed on the plan, we decided on the plate's dimensions. The pitot base location puts the point of the tube just in front of the leading edge of the wing. Perfect! Dave used the Dynon template to cut the hole. I used the plate as a tmeplate to cut out the hole in the wing. Yikes. Test fit looks good and very clean. Of course, there will he several screw heads in the plate.

Dave does nice precision work.

Yikes, that's a big hole.
