41. The 380 and 550 engines were air-cooled with a system marketed by Suzuki as " Ram Air ". 42. The previous economy engine and standard 350 hp 400 CID Hemi engines, the Ram Air IV utilized hydraulic lifters. 43. In the unlikely event of double-engine failure these aircraft have ram air turbines to provide electrical and hydraulic power. 44. The centre provides student training in the Ram Air Progression System, Accelerated Freefall ( AFF ) and tandem skydiving. 45. The Ram Air V garnered much auto press publicity, but only a relative few were made available for sale. 46. The engine lid featured a large central ram air duct protruding above the roof; a rear spoiler was standard equipment. 47. Conventional traction kites use either a rigid frame inflated with a pump prior to launching or ram air inflated cavities. 48. Air flowing into the duct meets drag resistance from the radiator surface and is compressed due to the ram air effect. 49. The resulting stiction can temporarily prevent the rotor from turning when only the force of ram air is applied to the core. 50. A ram air turbine a small retractable propeller which can provide emergency power is also fitted in the wing root fairing.
