操作特性:
—发动机为二级机械增压,需2000m高度时手动切换。
—发动机混合比控制是手动的;如果高度高于3-4 km,需要贫油混合比来优化发动机运行。而且,贫油混合比还可以降低飞行中的油耗。
—发动机转速有自动调节器,其根据调节器控制杆位置保持对应的需用转速。调节器自动控制螺旋桨桨距来保持需用转速。
—水冷和滑油散热器风门是手动控制的。
—飞机仅有俯仰飞行操纵的配平。
—着陆襟翼由冷气驱动。襟翼只可完全放下,不可无级放下。由于致动器放下襟翼的力较弱,当空速大于220km/h时,气流会把襟翼压回收起位置。因此,请记住襟翼在高速时无法完全放下。在高速着陆进近时襟翼可能在着陆前分阶段放下。
—飞机有手动控制尾轮锁的功能。未锁定的尾轮有90°偏转限制。在长距离直线滑行时、起飞和着陆前应锁住尾轮。
—飞机有共用一个控制杆的差动气压机轮刹车。这意味着捏住刹车踩舵,反向一侧的机轮刹车会逐渐释放,导致飞机转向踩舵一侧。
—油量表安装在驾驶舱外左右机翼的油箱上。机翼油箱少于25升时以及中央供油箱(10升容量)的油量不测量。
—由于强气流,高速时无法开闭座舱盖。座舱盖只能应急抛弃,所以跳伞之前需先减速。
—虽然尾轮可以自由旋转,但是向后移动操纵杆会锁定尾轮,使其由脚蹬控制旋转。
Operation features:
- The engine has a two-stage mechanical supercharger which must be manually switched at 1200…1600m altitude.
- Engine mixture control is manual; it is necessary to lean the mixture if altitude is more than 3-4 km for optimal engine operation. Also, leaning the mixture allows a reduction in fuel consumption during flight.
- Engine RPM has an automatic governor and it is maintained at the required RPM corresponding to the governor control lever position. The governor automatically controls the propeller pitch to maintain the required RPM.
- Oil radiator shutters are controlled manually.
- Water radiator shutters can be controlled automatically and manually.
- The airplane can only be trimmed in the pitch axis.
- Landing flaps have a pneumatic actuator. Flaps can only be fully extended; gradual extending is impossible. Due to the weak force of the actuator the extended landing flaps may be pressed upwards by the airflow if the airspeed is more than 220 km/h. Remember that the flaps will not extend fully in case of high speed. In case of a high-speed landing approach the flaps may extend a few steps further right before landing.
- The aircraft has differential pneumatic wheel brakes with shared control lever. This means that if the brake lever is held and the rudder pedal the opposite wheel brake is gradually released causing the plane to swing to one side or the other.
- Fuel gauges are installed on left and right wing fuel tanks, outside of the cockpit. The central feeder tank (20 litres) capacity is not measured.
- It is impossible to open the canopy at high speeds because of the ram air, but there is an emergency jettison handle for bailing out.
Basic data and recommended positions of the aircraft controls:
- Starting the engine:
- recommended position of the mixture control lever: 100%
- recommended position of the radiators control handles: close
- recommended position of the prop pitch control handle: 100%
- recommended position of the throttle lever: 5%
- Recommended mixture control lever positions for various flight modes:
- When running the engine at low throttle near the ground, the mixture control lever should be in the position of about 50%.
- When the engine is running at full throttle near the ground, the mixture control lever should be in the 75-80% position.
- As you gain altitude, the altitude corrector closes. At 8-9 km altitude, the altitude corrector closes to 0%.
3.1 Recommended positions of the oil radiator control handle for various flight modes:
- takeoff: open 100%
- climb: open 100%
- cruise flight: open 30%
- combat: open 100%
3.2 Recommended positions of the water radiator control handle for various flight modes:
- takeoff: open 100%
- climb: open 100%
- cruise flight: open 40%
- combat: open 80%
- Approximate fuel consumption at 2000 m altitude:
- Cruise engine mode: 7.5 l/min
