What are Robinson (R-44), Bell 206 L4, Mi-172, Bell 407, Daulphin SA 365 N ?
Explanation
The Robinson (R-44), Bell 206 L4, Mi-172, Bell 407, and Dauphin SA 365 N are all specific models of helicopters that constitute the fleet operated by Pawan Hans Helicopters Ltd (PHHL). Pawan Hans was established in 1985 to provide helicopter services to India's petroleum sector, connect inaccessible hilly regions, and promote tourism [c1][c2]. Evidence confirms that the Pawan Hans fleet specifically includes the Bell 206 L4, Bell 407, and the Mil Mi-172, which is a civil variant of the Mi-8 helicopter [t4]. The Robinson R-44 is a widely used piston-powered helicopter often utilized for training and private use [t1][t7], while the Dauphin SA 365 N is a well-known medium-weight multipurpose helicopter frequently associated with PHHL's offshore operations. These models are distinct from the fixed-wing aircraft used by Indian Airlines or the naval vessels used by the Indian Navy.
