The new gearbox is factory installed from serial numbers (Werk-Nr.) V00036 on, or may be retrofittet as a unit together the pneumatic clutch. The modified transmission ratio allows simpler handling during pre-rotation using a slightly increased clutch speed. The configuration state pneumatic clutch III (new 90-degree- gearbox) is easily discernible by using a black OVERDRIVE push button instead of a red one. In case of pneumatic clutch III (new 90-degree-gearbox), identified by a black OVERDRIVE push button, the following changes have to be respected: ref. 2.6 (replacing): 2.6 Powerplant Limitations and Instrument Marking Engine Speed Marking Maximum engine speed Red radial 5800 RPM 5 minute take-off power regime Yellow arc 5500 ñ 5800 RPM Maximum continuous power Green arc 1400 ñ 5500 RPM Recommended pre-rotation clutch speed Green radial 2100 RPM Yellow arc 0 ñ 1400 RPM ref. 4.8 (replacing): 4.8 Take-off Procedure  Check relative wind  Maintain control stick in forward position with right hand  Switch pneumatic mode selector to FLIGHT and return to brake with left hand  Hold wheel brake without having locking pawl engaged  While holding wheel brake adjust 2100 RPM with throttle  Activate and hold pre-rotator  Let pneumatic clutch fully engage (stabilization at about 110 rotor RPM). If necessary release pre-rotator button momentarily and press again to maintain engine RPM within green arc, respectively prevent engine from stalling  Carefully increase throttle (~ 150 R-RPM/sec) to 200 R-RPM ñ max. 240 R-RPM  Release pre-rotator button  Gently move the control stick fully aft (stick travel ~ 1 second)  Release wheel brake with throttle unchanged  Monitor rotor speed and adequately increase throttle to take-off power Flight Manual Cavalon SUPPLEMENT AutoGyro FOM Cavalon Rev. 1.3 ñ Issue Date 01.06.2012 Supplement - 2 INTENTIONALLY LEFT BLANK
