New Diesel Engines On The Way for RV Builders

DeltaHawk published a short video of a recent test flight using a Van’s RV-14, giving builders and buyers a hint of what’s to come. “On the average mission," DeltaHawk said, "a jet-fueled DeltaHawk engine is up to 40% more efficient than an Avgas engine—improving range, increasing available payload and lowering cost of ownership. Multiple redundancies increase safety. And operating with widely available jet fuel, you can fly anywhere in the world without the worry of finding places to top off. But we didn’t stop there. Our engine’s small, aerodynamic profile allows an elegant cowl design with less drag, further increasing fuel efficiency. To do that, we literall

President Trump has signed a series of executive orders that claim to strengthen domestic drone manufacturing, enhance public safety, and revive civilian supersonic air travel. The actions reflect a broader federal effort to reduce US reliance on foreign drone technology, particularly from China. One order directs the FAA to allow commercial and public safety operators to fly drones beyond the visual line of sight, a significant change from existing restrictions. It also supports testing of vertical takeoff and landing aircraft for potential roles in cargo delivery,

From 2022 (YouTube Edition): Still Life with Verve

David Uhl was born into a family of engineers and artists—a backdrop conducive to his gleaning a keen appreciation for the form, function, and beauty of machines, and an intuitive understanding of the passions they inspire. Mr. Uhl purchased his first motorcycle in 1988, and his pencils, brushes, and artistic sensibilities hastened to document the arcane syncretisms of line, curve, and color by which the brute concomitantly aroused the intellectual and visceral ecstasies. In 1993 Uhl got about the business of producing numerous best-selling artworks for Harley-Davidson ap

Fuel Remaining A phrase used by either pilots or controllers when relating to the fuel remaining on board until actual fuel exhaustion. When transmitting such information in response to either a controller question or pilot initiated cautionary advisory to air traffic control, pilots will state the APPROXIMATE NUMBER OF MINUTES the flight can continue with the fuel remaining. All reserve fuel SHOULD BE INCLUDED in the time stated, as should an allowance for established fuel gauge system error.
