"The Pioneer Edition is for those that want to be part of the group of 90 that writes history with us. They will be at the forefront of a mobility revolution, where we will no longer have cars that can only drive." - R. Dingemanse, CEO PAL-V

The Pioneer edition will be delivered prior to any other PAL-V in your country. Only when we have delivered the Pioneer edition we will commence the delivery of the PAL-V Liberty Sport.



DAHER UNVEILS NEW TBM 940 AT OWNERS SEMINAR


Daher launched the TBM 940, an upgraded version that succeeds its top-of-the-line 930 with new features that include an integrated autothrottle, automatic deicing system, and cabin improvements, the airframer announced today at the TBM Owners and Pilots Association Safety Seminar in Pompano Beach, Florida. Photo © Daher

"This newest TBM family member underscores our firm commitment to constant improvement for the ownership and operational experience with our very fast turboprop aircraft," said Daher Airplane Business Unit senior v-p Nicolas Chabbert.

The 940's autothrottle is the first to be installed on a single-engine turboprop weighing less than 12,500 pounds, Daher claims, and adjusts the airplane's speeds based on the preset flight profile. The autothrottle also allows the 940 to be operated at the edge of approved power regimes for the Pratt & Whitney Canada PT6A-66D.

The airplane also gets more automation on the deicing system, which is automatically activated when icing or ice accumulation is detected and the pilot doesn't take action. The cabin gets redesigned seats, a central shelf with side storage, an additional 115-volt electric outlet at the right rear seat panel, and a USB port bringing the total to six passenger and three pilot ports.

The 940's range of up to 1,730 nm is unchanged from the 930. FAA and EASA certification of the airplane, priced at $4.13 million with standard equipment, is expected next month.



COMING SOON-COULSON'S CH-47 & CH-60 HELITANKERS


These helitankers will be coming Summer 2019! Operating in both aerial firefighting and heavylift, through a joint venture with Unical.

Coulson Aviation is a family owned business that was founded in 1984 and has enjoyed 34 years and a 150,000+ safe flight hours of operations worldwide between off shore oil and gas, firefighting and heavy lift with its fleet of Sikorsky S-61 26 passenger heavy lift helicopters.

Coulson Aviation now operates a diverse fleet of Firefighting aircraft with its fixed wing air-tankers C-130 Hercules, Boeing 737 and its helicopter fleet of Sikorsky S-61 and now the Boeing CH-47 and Sikorsky UH-60.

Coulson Aviation is expanding its rotary-wing capabilities and has entered into a joint venture with Unical Aviation to bring what they claim will be the most advanced firefighting Chinook and Black Hawk helicopters to the market.

The Black Hawk and Chinook modifications follow Coulson Aviation's recently-completed, large-scale project to modify Boeing 737s into multi-use air tankers; Coulson Aviation is the first in the world to modify the 737 into what it is calling the Fireliner.

Coulson Aviation plans to modify the fuselage on the CH-47, cut the floor of the aircraft and install a 3,000-gallon tank, called the RADS-L (large). "It's going to be a newer generation Skycrane tank," Britt Coulson said, adding that the tank in the Chinook can be removed in a two-hour time period.

The company will do the same modifications on the Black Hawk, but with a smaller, 800- to 1,000-gallon removable tank, called RADS-M (medium).

Coulson Aviation's RADS series of tanks feature a common touch screen SMART Delivery System Controller, which allows for automated target drops for the company's night vision goggle firefighting program. The touch screen technology also provides the ability to adjust flow rates based on speed and altitude.



AIRBUS HELICOPTERS UNVEILS NEW H145 AT HELI-EXPO 2019


Airbus Helicopters is unveiling a new version of its best-selling H145 light twin-engine helicopter at Heli-Expo 2019 in Atlanta. Visible on the Airbus booth at the show, this latest upgrade brings a new, innovative five-bladed rotor to the multi-mission H145, increasing the useful load of the helicopter by 150 kg while delivering new levels of comfort, simplicity and connectivity.

The H145's new five-bladed rotor brings a significant increase in overall performance, with a maximum take-off weight raised to 3,800 kg and a useful load now equivalent to the aircraft's empty weight. The simplicity of the new bearingless main rotor design will also ease maintenance operations, further improving the benchmark serviceability and reliability of the H145, while improving ride comfort for both passengers and crew. The reduced rotor diameter will allow the H145 to operate in more confined areas.

The new H145 introduces new levels of on-board connectivity to customers and operators through the integration of the wireless Airborne Communication System (wACS), allowing seamless and secure transmission of data generated by the helicopter in real-time, including in-flight.

EASA certification of the new H145 is planned for early 2020, with first deliveries to follow later that year. This upgrade will also be offered to current H145 customers as a retrofit option in order to deliver the same improvements in terms of useful load, simplified maintenance and comfort to the existing version of the H145.

Powered by two Safran Arriel 2E engines, the H145 is equipped with full authority digital engine control (FADEC) and the Helionix digital avionics suite. It includes a high performance 4-axis autopilot, increasing safety and reducing pilot workload. It's particularly low acoustic footprint makes the H145 the quietest helicopter in its class.



ROSTEC'S VRT500 PROTOTYPE TO BE READY BY END OF 2019

Russian Helicopters, part of Rostec State Corporation, will produce a light utility helicopter prototype, called the VRT500, by the end of 2019. The prototype is being designed by VR-Technologies design bureau. Rostec explains the helicopter's rotor system strength tests are now underway and VR-Technologies will soon begin aerodynamic tests, which it specializes in.

The helicopter is to be supplied in the following configurations: passenger, utility, cargo, training, VIP, and Medevac. VRT500 will be the first Medevac helicopter in the world in the segment of helicopters with maximum take-off weight up to two tons, explains Rostec, to ensure loading and unloading of unified gurneys through the rear cabin doors. Rostec states this simplifies the process and significantly reduces loading time.

Rostec continues to explain the VRT500 combines high flight performance and low pricing and operating costs. The company also claims it will hold the largest transport and cargo cabin in its class, with a total capacity of up to five people. Rostec predicts these characteristics will allow the VRT500 to occupy up to 15 per cent of the global market of civil helicopters with maximum take-off weight up to two tons.

"We expect to produce and sell an average of 700 helicopters by 2030," said Alexander Okhonko, VR-Technologies director general.

According to Okhonko, about 30 per cent of supply would be destined to the countries of Latin America and the Caribbean and about 15 per cent would be sent to North America, Asia-Pacific region, Europe, Russia and CIS.

VRT500 is a light single-engine helicopter with coaxial rotor scheme and 1600 kg take-off weight. Rostec explains the helicopter, featuring a glass cockpit avionics suite, will be capable of accelerating up to 230 km/h and will achieve a range of up to 1,000 km and payload of up to 750 kg.



URBAN AIR MOBILITY: ON THE PATH TO PUBLIC ACCEPTANCE


Are people ready to see their sky filled with aircraft, drones and other aerial vehicles? The answer is increasingly yes, according to a recent preliminary study on public acceptance for Urban Air Mobility. Image © Airbus.

Look up at the sky and you are bound to see a commercial aircraft or two disappearing behind the clouds. Perhaps a helicopter is surveying traffic above your city's tallest skyscrapers. Maybe a drone is filming landscapes in your neighbourhood.

A century ago, nobody ever would have imagined so many aircraft in the sky at any given moment. But today, our skies are busier than ever: current air traffic has quadrupled in the last 30 years and is set to double in the next 15.* And change is on the horizon again. Recent developments-in battery capacity, autonomy and on-board technology-are making new kinds of aerial vehicles possible. These vehicles can fly higher-and lower-than ever before and offer new possibilities, from parcel-delivery drones to an air taxi service. This is the sky of the future, powered by Urban Air Mobility (UAM) solutions.

"Our aim is to bring the public's voice to the table to create an ecosystem that better prepares cities and city dwellers for autonomous and electric aerial vehicles in a way that takes into account their desires, hopes and fears." Jessie Mooberry, Airbus UTM Head of Deployment

But how ready are people to see their sky filled with even more aerial vehicles-of various shapes and sizes-zipping around above their heads?

A recent preliminary study on UAM public acceptance addresses that very question. Airbus UTM, a division of Airbus' Urban Air Mobility Unit, conducted the study-surveying 1,540 people from Los Angeles, Mexico City, Switzerland and New Zealand-to determine their perceptions on safety, noise, inequity, visual pollution and privacy in relation to UAM deployment. This deployment component, known as unmanned traffic management (UTM), is critical to making UAM a reality because it regulates how new aerial vehicles (air taxis, delivery drones, etc.) can safely enter and share our future skies.

According to the study, nearly one in two people surveyed are in favour of UAM deployment. In fact, 44% indicate they support, or strongly support, the initiative.

The findings also reveal that 41% of participants perceive these aerial vehicles to be safe or very safe. Moreover, safety (55%) ranks as participants' leading concern for UAM implementation in their communities, followed by sound types (49%) and sound volume (48%) generated by the aerial vehicle.



"Communities need to be educated on UAM to facilitate public acceptance," Airbus UTM Head of Airspace Management Isabel Del Pozo De Poza said. "From our perspective, the study findings are very positive and demonstrate there's growing support."





Algeria, Aun Beida Airport: A Beechcraft 1900D operated by Tassili Airlines suffered a left-hand main landing gear collapse while landing at Ain Beida Airport, in Ouargla, Algeria. The aircraft sustained unknown damage and there were no injuries between the 16 occupants on board.

Cote d'Ivoire, North of Abidjan: A Airbus A380-861 operated by Air France with 501 on board en-route from Abidjan-Felix Houphouet Boigny Airport to Paris-Charles de Gaulle Airport was climbing to the cruising altitude shortly after midnight when one of the engines failed. The flight crew decided to return to Abidjan, where a safe landing was made. The engine had suffered a compressor stall causing damage to several fan blades as well as damage to the interior of the engine cowling.

UK, London Stansted: A Laudamotion Airbus A320-200 was accelerating for take-off from Stansted for a flight to Vienna (Austria) when the crew rejected take-off after a loud bang was heard. The aircraft stopped about 270 meters/890 feet down the runway. An emergency evacuation via slides was performed. Eight passengers received minor injuries as result of the evacuation. A ground observer reported a streak of flames came out of the left hand engine followed by white sparks just when the aircraft had moved a few meters.

USA, Presque Isle: A Commutair Embraer ERJ-145 with 28 passengers and 3 crew on board operated on behalf of United, on a flight from Newark was on final approach to Presque Isle's Airport when the crew initiated a go around from about 2000 feet MSL. The aircraft positioned for another approach to runway 01 and continued for a hard touch down. The aircraft veered right off the runway, all gear collapsed. A pilot and three passengers received minor injuries, the aircraft sustained substantial damage.

Colombia, Villavicencio: A Laser Aereo Colombia Douglas DC-3 on a flight from San Jose del Guaviare to Villavicencio with 14 people on board, was on approach to Villavicencio when the crew declared an emergency. The aircraft subsequently lost height and impacted ground at La Bendicion about 2.2nm south of the aerodrome and burst into flames. All occupants perished in the accident.

Guatemala, Escuintla: A North American T-28B operated by Strong Tower Services LLC crashed during an aerial show. The pilot was injured, and the mechanic was killed. The aircraft damaged beyond repair.





13 MARCH 1967

South African Airways Flight 406, a Vickers Viscount 818, crashes into the sea while on approach to East London, South Africa, killing all 25 passengers and crew on board. The pilot of the plane suffered a fatal heart attack while on approach and the co-pilot was unable to regain control of the aircraft.

South African Airways Flight 406, also known as the Rietbok Crash, was a scheduled passenger flight on 13 March 1967 that crashed into the sea on approach to East London, South Africa. The air accident report speculated, without supporting evidence, that the pilot of the plane suffered a heart attack while on approach and the co-pilot was unable to regain control of the aircraft.

Captain Lipawsky's day started with a flight departing from Johannesburg in the afternoon on a flight to Port Elizabeth with stopovers in Bloemfontein and East London. After take-off from Jan Smuts Airport (now O. R. Tambo International Airport), the front nose wheel would not retract due to mechanical malfunction. The aircraft returned to the airport and repaired, and the same plane was used to continue the flight.

At 4:41 pm GMT, Flight 406 took off from Port Elizabeth, and a 4:58 GMT, a weather report for East London was given. Acknowledgement of receipt of the weather report was given a minute later, and the pilot further requested descent clearance from flight level 90 (about 9,000 feet), which was granted. Air traffic control at East London requested the pilot to radio when he passed 4,500 ft. The pilot was recorded at Port Elizabeth tower saying that he was descending through 4,000 ft, seaward of the coastline and about 20 miles away from landing at 5:06 pm GMT.

The pilot was made aware that lights for both runways were on, but runway 10 was not available due to poor visibility. At 5:09 pm GMT (estimated), the pilot radioed to say he was at 2,000 ft and had the coast in sight. After this transmission, the plane was not heard from again.

The rescue attempt and later investigation were complicated by the plane crashing into the sea at night. The investigators were unable to recover the plane or the bodies of the passengers. The official investigation believed the plane was airworthy at the time it hit the water. Since the aircraft was airworthy, the investigation concluded the accident had two possible causes. The most likely cause was the pilot having a heart attack and the co-pilot being unable to recover the plane before it crashed.

The original report admitted the accident could have occurred due to spatial disorientation of the pilot, but believed that this was unlikely due to the pilot's experience level.

Judge Cecil Margo, one of the original investigators, later stated in his memoir 'Final Postponement' that he believed the plane crashed due to separation of the wing. At the time of the crash four Vickers Viscounts had been lost in crashes, two due to structural failure, and two over water with unknown cause. Another Viscount was lost over the sea on its way to Ireland, and yet another was lost over land in Australia. The crash in Australia allowed investigators to find the cause of in-flight disintegration, a failed wing spar.
