Chapter 21 – Fuel Pump Fittings

I finally knocked another item off my list  by giving the folks at EFII a call to order a couple of 90° fittings.  Unlike standard right angle fittings, these 90° fittings supplied by EFII can be clocked into any orientation so the exact angle of the connected fuel lines can be dialed in.

I need these right-angle fittings since I’ll be placing the fuel pump in the hell hole mounted on the underside of the CS spar.  The awesome folks at EFII quickly sent me out a pair of the 90° fittings with the only requirement that I send back the stock straight fittings.

Here’s my newly configured fuel pump, now ready for install!

Chapter 22 – Trio Pro Pilot on deck!

Today I finally received one of my instrument panel items that I’ve had on the list of things to buy for years now!  About a week ago I pulled the trigger on the Trio Pro Pilot Autopilot control head.  If you recall, I bought the servos from a guy off of eBay a couple of years ago and had them sent straight to Chuck at Trio who upgraded and ops checked them to ensure all was good.

This autopilot unit has the GPS Steering (GPSS) and GPS Vertical Steering (GPSV) options on it, with the GPSS allowing the Pro Pilot to receive GPSS commands from the GRT EFIS or Garmin via ARINC 429 data outputs.  The GPSV allows the autopilot to receive pitch steering commands from a WAAS GPS receiver for precision approaches using GPS.

In addition, after a lot of discussion over the years, Chuck tweaked one of the pull up resistors in this Pro Pilot’s innards so that it can receive fuel data from the FT-60 Red Cube fuel flow meter along with the GRT EFIS.  This gives me fuel management on both the EFIS and the Pro Pilot, which provides some pretty nifty fuel flow information.
