The R44 information is based around the Raven II (Clipper II with floats). To avoid confusion the R44 "ENG" variant cannot fly with floats & uses an SD 42x camera (7.8mm to 328mm).

*1: The fuel duration of both aircraft will increase at lower airspeeds. However the manufacturers do not publish comparable data for lower speeds, hence the use of cruising speed data for this comparison.

*2: Please advise us in advance of any planned night flying, as Pilots and Aircraft need to be suitably rated for this type of work.

*3: The aircraft must be flown so that it can auto-rotate safely into a clear area (outside of R160).

The above data is a simplified for the ease of presentation and offered as a quick guidance tool in good faith. More detailed information can be obtained upon request. Arena is able to offer both single & twin engine aircraft to suit each individual mission.
