    853 Scott Hamilton
    Jul 2 2025
    Guest Scott Hamilton is fresh from the Paris Air Show, and we talk about next-generation aircraft and engines, industry sustainability, the supply chain, and Boeing’s path back. Also, an NTSB safety recommendation for the CFM Leap-1B engine, and the possibility of restarting production of the C-17. Guest Scott Hamilton Scott Hamilton is the Founder and Managing Director of Leeham Company and has spent more than four decades in the commercial aviation industry. Leeham News and Analysis has been a go-to source for spotting trends and providing verified, credible, relevant aviation news that’s impartial and unbiased. Leeham Consulting Services provides expertise in several areas, including aircraft economic analysis, lease and return condition analysis and negotiations, aircraft product and strategy analysis, fleet planning and contract negotiations, market demand analysis, and MRO strategy. In our conversation with Scott, we looked at some of the technologies that may appear in next-generation aircraft. That includes ducted and unducted engines, as well as developments with geared fans. In public, the OEMs tout their own technology choices, but in reality, they are quietly working on multiple options. We touch on Boeing’s ability to make the financial investment required to proceed with a single-aisle replacement, and on the company’s path to recovery. Scott provides some observations on this year’s Paris Air Show, including the low-key participation by Boeing. Scott offers his thoughts on electric aircraft, alternative fuels, and the airline industry goal for net-zero carbon emissions by 2050. Scott’s book, Air Wars: The Global Combat Between Airbus and Boeing, was published in 2021. This coming September, a sequel titled The Rise and Fall of Boeing and the Way Back will be published and available on Amazon. Follow Leham News and Analysis on X, Bluesky, and Facebook. Aviation News Boeing Calls For Next-Gen Engine Info For Future Single Aisle Boeing issued a request for information (RFI) to engine manufacturers for advanced ducted propulsion systems in the 30,000-lb-thrust class. That thrust class is suitable for powering a future single-aisle replacement for the 737. Rolls-Royce and Pratt & Whitney are likely to respond to the RFI with geared, ducted turbofans, which they are proposing to Airbus for its next-generation single aisle (NGSA). CFMI will likely respond with a ducted engine based on technology from its Revolutionary Innovation for Sustainable Engine (RISE) unducted open fan program. Engine makers tout “Plan A” but have “Plan B” backups in R&D Each engine OEM has a vision for future engines (open fan, ducted fan, geared fan), but is each company also developing an alternative at the same time? PW’s sister company, Pratt & Whitney Canada, has publicly disclosed its development of an Open Fan engine for a new 70-100-seat aircraft designed by the start-up company MAEVE Aerospace. See: Maeve Redesigns Its Hybrid-Electric Regional Aircraft MAEVE Aerospace concept. NTSB issues rare safety bulletin about potential issues with Boeing 737 Max engines Two bird strike incidents in 2023 with CFMI LEAP-1B engines caused smoke to enter the ventilation system. The NTSB has issued an urgent safety bulletin, asking operators to inform flight crews of the potential hazard and calling for modifications to engine software. The NTSB notes that Boeing has revised flight manuals. GE Aerospace says it had already made changes. See: NTSB Recommends Modifications to LEAP-1B Engines The NTSB found that the engine load reduction device, or LRD, a safety feature designed to reduce the severity of vibrations transmitted from a damaged engine to the airframe, can result in damage to the engine oil system. Such a condition can allow smoke from hot oil to enter the ventilation system and ultimately the cockpit or passenger cabin. Boeing in Talks to Restart C-17 Production

    852 Ram Air Turbine

    The Air India B787 fatal crash and the ram air turbine, how your personal travel data is sold, next generation commercial aircraft engines, personal electric flying machines that are becoming dangerously affordable, and GippsAero is coming back to Australia to build the GA8 airvan. Aviation News Indian authorities begin investigating Air India crash in which 1 passenger survived India's Aircraft Accident Investigation Bureau (AAIB) is investigating the fatal crash of an Air India B787. Of the 242 passengers and crew aboard, one passenger survived. Numerous theories are being speculated in the press, including loss of power by both engines, failure to set the flaps properly for takeoff, and erroneously retracting the flaps instead of the landing gear. Some say the Ram Air Turbine appears to be deployed in one video. The Ram Air Turbine (RAT) extends from the fuselage or the wing to generate power in an emergency. Twin blades [corrected] spin a shaft connected to either an electrical generator or a hydraulic pump that drives a generator. The B787, A320, and A380 Ram Air Turbines are produced by Collins Aerospace. The company manufactures hydraulic, electric, and hybrid RATs that generate both electric and hydraulic power. Safran also produces Ram Air Turbines. Ram Air Turbine. Image courtesy Collins Aerospace.

Airlines Secretly Sold One Billion Passenger Records—Now The Government Can Track Where You Travel The Airlines Reporting Corporation (ARC) is a major provider of settlement services for the airline industry. Clients include airlines, travel agencies, and corporate travel departments. ARC is owned by the airlines and sells passenger names, full domestic flight itineraries, and payment details (e.g., credit card used) through its “Travel Intelligence Program” (TIP). Customs and Border Protection (CBP) is reportedly purchasing this data. Senator Ron Wyden (D-OR) is critical of this practice and wants airlines to explain why they allow ARC to resell this information. CBP claims they adhere to strong privacy policies, and only use the data for open investigations. Open Fan Would Be Suboptimal On Narrowbody, RTX Chief Scientist Says The next generation of single-aisle aircraft will need to offer at least a 20% fuel burn improvement. Some of that will likely come from the airframe, and most will come from the power plants. The next generation of turbofans under development includes the CFM International open-fan RISE demonstrator and geared turbofans from Pratt & Whitney. Thermal efficiency vs. propulsive efficiency: Thermal efficiency measures how effectively an engine converts fuel energy into mechanical work. Propulsive efficiency measures how efficiently the engine converts mechanical energy into useful thrust. Both are dimensionless ratios, typically expressed as a percentage (%). The overall efficiency of the engine is the propulsive efficiency multiplied by the thermal efficiency.

  • 851 Supersonic Flight Ban

    851 Supersonic Flight Ban
    Jun 11 2025
    We speak with the Chief Pilot for a large European carrier about taking delivery of his airline’s first A321XLR, and with a fractional ownership pilot about changing from the Phenom to the Challenger Global 300. In the news, we look at lifting the supersonic flight ban, revamping the Army flight school, denying an unleaded avgas motion, reforming flight delay compensation, and considering the Fire Boss air tractor for fighting wildfires Guests Captain Al Evan is the Chief Pilot for a large European low-cost carrier. He was the Airbus and Pratt & Whitney liaison for the delivery of his airline’s first P&W-powered A321XLR. Captain Al and Micah Stephen Ivey is a pilot for a large fractional ownership company. He recently changed from the Phenom to the Challenger Global 300. Stephen Ivey Aviation News U.S. Lifts 50-Year Ban on Supersonic Overland Flights Supersonic flight by civilian aircraft over the U.S. was originally banned in 1973 due to concerns about sonic boom noise pollution and potential damage on the ground. However, on June 6, 2025, President Donald Trump signed an executive order directing the FAA to repeal the ban and replace it with an interim noise-based certification standard. The Order instructs the FAA Administrator to establish a standard for supersonic aircraft noise certification that considers community acceptability, economic reasonableness, and technological feasibility. Army revamps flight school after deadly crashes The U.S. Army is overhauling pilot training to focus on fundamental skills. The change in 2013 from TH-67 training aircraft to the LUH-72A Lakota helicopters contributed to the need for training adjustments. The Army determined that the quick advancement of inexperienced crews was leading to unsafe situations. The Army is considering outsourcing pilot training to a contractor-owned-and-operated schoolhouse. Judge Denies G100UL Motion A California judge ruled that GAMI’s G100UL is not "commercially available" and therefore cannot be mandated for sale in California to replace leaded aviation fuel. This comes after a motion by the Center for Environmental Health to enforce a 2014 consent agreement that says FBOs and distributors must sell a lower lead alternative that is “commercially available.” The judge ruled that the fuel must first be universally available to all piston-powered aircraft. There must be a “general consensus” from the industry and potential customers that the fuel is safe and appropriate for their use. Europe Flight Delay Compensation Reform Coming, And It’s Bad News The European Union's flight delay compensation policy EC261 (sometimes called EU261), has been unchanged since 2014. Some EU transport ministers have been discussing reforms where passengers would have to experience longer delays before being eligible for compensation. Currently, compensation ranges from €250 to €600: €250 compensation if you’re delayed by at least two hours for flights under 1,500km (930 miles). €400 compensation if you’re delayed by at least three hours for flights of 1,500-3,500km (930-2,200 miles). €600 compensation if you’re delayed by at least four hours for flights over 3,500km (2,200 miles). A new proposal would: Provide €300 compensation if you’re delayed at least four hours for flights under 3,500 km. Provide €500 compensation if you’re delayed at least six hours for flights over 3,500 km. See DOT’s Airline Customer Service Dashboard. What is a Fire Boss? The agriculture aircraft that doubles as a water bomber Dave Frisch, the president of Portage Aircraft Specialties Ltd., sells Air Tractors designed for agricultural spraying. He says that if you add specially designed floats, these aircraft become a type of water bomber known as the Fire Boss. Being a small aircraft, the Fire Boss can scoop water out of smaller bodies of water and get into tighter spaces.

I am on my 3rd career, as a aviation cadet at CAE in Phoenix, Currently I seek out as much knowledge regarding aviation as possible because i did not know what a Cessna was until 2019 and I’m in my 40’s. Thus aviation has been an uphill battle for me. I literately am trying to go from zero to ATP. “drinking from the fire hose. I appreciate the variety of backgrounds and opinions on so many different topics. I learn more from the podcasts than I do at CAE.

great variety of opinions and backgrounds
