Author suspects max/min are reversed. before_takeoff normal Engine Run-Up and Vital Actions 7 caution no no 0 Aerobatics forbidden with less than 4.5 gallons of fuel remaining. takeoff normal Takeoff 0 challenge yes no 0 Apply full throttle takeoff normal Takeoff 1 challenge yes no 0 Expect to push on the 'wrong' foot due to engine rotation direction takeoff normal Takeoff 2 action yes no 0 Rotate 120 km/h (65 kt) takeoff normal Takeoff 3 note no no 0 Take-off roll in ISA conditions is 590 ft at maximum weight. after_takeoff normal After Takeoff 0 action yes no 0 Raise gear BELOW 200 km/h (108 kt) after_takeoff normal After Takeoff 1 challenge yes no 0 After selecting gear up, hold lever until 'three reds', then return lever to neutral approach normal Circuit and Approach 0 action yes no 0 Lower gear AT 200 km/h (108 kt) approach normal Circuit and Approach 1 challenge yes no 0 After selecting gear down, hold lever until 'three greens', then return lever to neutral approach normal Circuit and Approach 2 action yes no 0 Extend flaps AT/OR BELOW 170 km/h (92 kt) approach normal Circuit and Approach 3 action yes no 0 Fly approach 170 km/h (92 kt) slowing to 120 km/h (65 kt) at threshold approach normal Circuit and Approach 4 note no no 0 Without flaps, forward view from rear seat is virtually nil; a curved approach is needed. landing normal Landing 0 challenge yes no 0 Keep the canopy lock pin in place in the rail hole landing normal Landing 1 challenge yes no 0 Lower nose after touchdown landing normal Landing 2 note no no 0 High wing-loading means no tendency to float. landing normal Landing 3 note no no 0 With practice, landing roll can be as short as 300 m (985 ft). forced_landing normal Forced Landing 0 challenge yes no 0 Leave gear retracted for dead-stick landing forced_landing normal Forced Landing 1 note no no 0 Standard drill is to leave gear retracted to flatten the descent profile. forced_landing normal Forced Landing 2 note no no 0 Brakes remain usable with gear up. forced_landing normal Forced Landing 3 note no no 0 With gear up, the undercarriage remains partially exposed to minimize damage in a wheels-up landing. reference normal Reference 0 note no no 0 Performance: climb to 3,000 ft in 98 seconds; cruise 140-145 kt at 75 per cent power; fuel burn just over 13 US gal/hr at 140 kt cruise. reference normal Reference 1 note no no 0 Endurance in excess of 2 hours with 45 minutes reserve; maximum range 275 nm at slightly reduced cruise speed. reference normal Reference 2 note no no 0 G limits: unlimited aerobatics certified at max takeoff weight 1,305 kg. reference normal Reference 3 note no no 0 Engine: Ivchenko M-14P 9-cylinder radial, 360 hp. reference normal Reference 4 note no no 0 Pneumatic system used for engine starting, flaps, gear, and brakes. reference normal Reference 5 note no no 0 RPM gauge is calibrated in percent of maximum rather than RPM. reference normal Reference 6 note no no 0 Artificial horizon is inverted in presentation: top half of ball is brown, bottom half is blue. reference normal Reference 7 note no no 0 Rear cockpit has controls to deliberately fail certain systems in the front cockpit. reference normal Reference 8 note no no 0 Gear lever is pneumatic and returns to central neutral position when not required. reference normal Reference 9 note no no 0 Brakes are operated by a stick-mounted lever; pneumatic brake noise resembles a bus/lorry stopping.
