The Eurocopter AS350 Écureuil is a single-engine light utility helicopter originally designed and manufactured in France by Aérospatiale and Eurocopter (now Airbus Helicopters). The type is known for its high-altitude performance and has seen use by operators in such environments. The AS350 was also developed to comply with the noise requirements in place in locations such as national parks; the in-cabin noise levels are such that passengers may also readily converse during flight.
