Getting Fuelish

Fuel flows in from the right, through the filter, the shut-off valve, and the red cube - then on to the engine.

One of the interesting things about the Subsonex kit is that it is easy to skip around from one task to another as you're building. If I get tired of attaching piano hinges for control surfaces for instance, I can jump over to installing the oxygen system. Exhausted by working down in a footwell to install a ruder pedal? Time to go work on the fuel system! Continue reading "Getting Fuelish"

Nope, no, no way... flying 30+ years!

kinked fuel line

I am often amazed at just how big our margins can be in aviation. Engineering margins, that is - operational margins are as big (or as small) as pilots want to make them. Here is a good case in point. This is the right tank-to-selector fuel line off of a very early two-seat RV. It's been flying for probably well over 30 years. See that crimp? Look more closely - inside the crimp are three very sharp depressions that look like they were made with teeth from a tool of some sort. If you look inside the end of the tube with a bright light, you can actually see each individual tooth mark! Continue reading "Nope, no, no way... flying 30+ years!"

System 32 Seen at Reno

Heart of the new System 32 engine management is its ECU. The blue anodized aluminum housing contains one complete computing unit along with its associated cable terminals and an SD card reader. There are two of these boxes per system; they can be mounted piggyback if desired.

Introduced late last week, the first look at the brand new EFII System 32 engine management system hardware is possible in the pits at the National Championship Air Races in Reno, Nevada as of today. Continue reading "System 32 Seen at Reno"

Belite Introduces Safety Enhancing Fuel / Water Discriminator

Belite RADIANT Technology released a new product that enhances safety by alerting the pilot to fuel exhaustion or water contamination.

The new RADIANT Fuel / Water Discriminator will instantly tell the pilot or vehicle operator if the fuel line is empty or if liquid water is detected in the fuel line. This innovative product is based on patent pending technology and is installed in the fuel line. It increases pilot safety by alerting a pilot to switch tanks in the event of fuel exhaustion on one tank and also provides a positive and immediate indication if liquid water is present in the fuel line.
