Aircraft model terminology:

油门位置: 油门越大，螺旋桨拉力或推力越大，飞机增速快，起飞滑跑距离就短。所以，一般应用zui大功率或zui大油门状态起飞。

Throttle position: The higher the throttle, the greater the propeller pull or thrust, the faster the aircraft accelerates, and the shorter the takeoff and roll distance. Therefore, it is generally used for takeoff with high power or high throttle.

离地迎角: 离地迎角的大小决定于抬前轮或抬机尾的高度。离地迎角大，离地速度小，起飞滑跑距离短。但离地迎角又不可过大，离地迎角过大，不仅会因飞机阻力大而使飞机增速慢延长滑跑距离，而且会直接危及飞行an全。

Angle of attack from the ground: The magnitude of the angle of attack from the ground depends on the height of lifting the front wheel or tail of the aircraft. High angle of attack from the ground, low ground speed, and short takeoff and running distance. But the angle of attack from the ground should not be too large. If the angle of attack from the ground is too large, not only will the aircraft slow down due to high resistance, but it will also directly endanger the flight safety.

襟翼位置: 放下襟翼，可加大升力系数，减小离地速度，因而能缩短起飞滑跑距离。

Flap position: when the flap is lowered, the Lift coefficient can be increased and the ground speed can be reduced, thus shortening the takeoff run distance.

起飞重量: 起飞重量加大，不仅使飞机离地速度加大，而且会引起机轮摩擦力增加，使飞机不易加速。因此，起飞重量加大，起飞滑跑距离增长。

Takeoff weight: An increase in takeoff weight not only increases the aircraft's ground clearance speed, but also causes an increase in wheel friction, making it difficult for the aircraft to accelerate. Therefore, the takeoff weight increases and the takeoff distance increases.

机场标高与气温: 机场标高或气温升高都会引起空气密度减小，一放面使拉力或推力减小，飞机加速慢；另一方面，离地速度加大，因此起飞滑跑距离必然增长。

Airport elevation and temperature: the elevation or temperature rise of the airport will reduce the Density of air. As a result, the tension or thrust will be reduced and the aircraft will accelerate slowly; On the other hand, as the ground clearance speed increases, the takeoff distance will inevitably increase.

跑道表面质量: 不同跑道表面质量的摩擦系数，滑跑距离也就不同。跑道表面如果光滑平坦而坚实，则摩擦系数小，摩擦力小，飞机增速快，起飞滑跑距离短。反之跑道表面粗糙不平或松软，起飞滑跑距离就长。

Runway surface quality: The friction coefficient of different runway surface qualities also affects the running distance. If the surface of the runway is smooth, flat, and solid, the friction coefficient is small, the friction force is small, the aircraft speed is fast, and the takeoff and taxiing distance is short. On the contrary, if the surface of the runway is rough or soft, the takeoff and running distance will be longer.

风向风速: 起飞滑跑时，为了产生足够的升力使飞机离地，不论有风或无风，离地空速是一定的。但滑跑距离只与地速有关，逆风滑跑时，离地地速小，所以起飞滑跑距离比无风时短。反之则长。

Wind direction and speed: During takeoff and taxiing, in order to generate sufficient lift to lift the aircraft off the ground, regardless of whether there is wind or no wind, the airspeed above the ground is constant. But the distance of the taxiing is only related to the ground speed. When taxiing against the wind, the ground speed is small, so the takeoff taxiing distance is shorter than when there is no wind. On the contrary, it is longer.

滑跑坡度: 跑道有坡度，会使飞机加速力加大或减小。

Gliding slope: The runway has a slope that increases or decreases the aircraft's acceleration force.
