Airbus Helicopters' latest version of the H145 has set its skids down on the Aconcagua, the highest mountain in the Southern Hemisphere, which peaks at 6,962 metres. This is the first time a twin-engine helicopter has landed at this altitude.

The conditions for the mission were extreme, due to the atmosphere in the area and the winter season. The aircraft took off from Mendoza, Argentina, flew 30 minutes to the foot of the Aconcagua and then began its ascent. After 15 minutes of climbing, the helicopter landed at 1.45 pm on the summit, at a temperature of -22 degrees Celsius. The crew onboard the helicopter consisted of Alexander Neuhaus, experimental test pilot and Antoine van Gent, experimental flight test engineer.

“We had to stay focused on the mission due to severe winds with gusts up to 30 knots and the low air density. The handling qualities of the new H145 are excellent and combined with Helionix and its four axis-autopilot, we reached the summit safely,” explains Neuhaus. “The aircraft performed outstandingly. We flew over the summit of the Aconcagua and still had power reserves that would have allowed us take two people on board.”

The flight test was supported by the Fuerza Aerea Argentina, who provided aerial support with their Lama helicopters; Patrulla de Rescate de Alta Montaña de Policia de Mendoza, who assisted with a contingency plan; Parque Provincial Aconcagua, facilitating operations and logistics, and Helicopters AR, a local operator with over 15 years of experience flying in the Aconcagua area with its Airbus H125 helicopter.

On 14 May 2005, the flight test pilot Didier Delsalle landed a single-engine H125 on Mount Everest, the highest mountain in the world.

Prior to the successful high altitude test campaign in South America, the new H145 performed several test campaigns including in Spain at medium altitudes and Finland for cold weather. In total, more than 400 flight hours have already been clocked on the two five-bladed H145 prototypes to ensure EASA certification by early 2020, followed by FAA certification and first deliveries later that year.

The new version of the H145 was unveiled at Heli-Expo 2019 in Atlanta in March. This latest upgrade adds a five-bladed rotor to the multi-mission H145, increasing the useful load of the helicopter by 150 kg. The simplicity of the new bearingless main rotor design will also ease maintenance operations, further improving the serviceability and reliability of the H145, while improving ride comfort for both passengers and crew.
