(4).试车中发生飞机滑动、火警或其他不安全情况时，警戒人员应立即通知试车人员停止试车。

If there are unsafe conditions such as aircraft movement, fire and etc, guarders must inform persons in cockpit immediately to stop the test.

(二)．试车环境与条件

Environments and Conditions

1. 试车前，应根据风速、风向、试车场地等情况和试车要求，尽量将机头迎风停放，并注意：

Before test, try to put the aircraft nose windward according to wind velocity, wind direction, field condition and the requirements of engine run up test. And pay attention to the following items:

(1).试车要在指定的地点进行，地面应坚实清洁、无油污水分、无冰雪霜和其他杂物，飞机的四周应按规定留有足够的安全距离，不能紧靠停放的飞机和障碍物，包括机库和大型永久结构。飞机前方50米之内不允许有障碍物。

Engine run up test must be performed in the assigned area. Ground must be hard and clean, no oil, no water, no snow, no ice and other material on it. There must be enough safety space around the aircraft. The aircraft must keep clear to other parked aircrafts and obstacle, including garage and big permanent structures.

There must be fire-extinguishing equipments available at anytime near the field. They must be suitable to the engine, and have good performance.

(3).试车发动机的后吹气流区域内有其它飞机经过时，警戒人员应立即通知试车人员减速至慢车。当飞机离开危险区后，警戒人员应及时发出解除信号。

When other aircraft pass the exhaust area of test engines, guarder must inform the test persons immediately to decrease the engine power to idle. After the aircraft leave the exhaust area, guarder should inform the test persons in time.

(4) 如有车辆和人员企图通过危险区域时，警戒人员应予以制止，待试车结束后方可准其通过。

(5).寒冷天气，试车前应除尽冰霜并采取防冰措施。

Under cold whether condition, de-ice action must be performed before the test, and anti-icing is necessary.

2. 试车人员应在得到机场管理部门和地面警戒人员的许可后，才能开始试车。

Engine can not be run-up until the allowance was received from the airport management department and persons on guard.

(三)．试车安全规则

Precautions

1. 与试车无关人员不准进入驾驶舱，试车人员不得离开驾驶舱。

Persons not concerned are forbidden to enter the flight compartment and test persons should not leave the flight compartment.

2. 只有在试车人员的指挥下，才允许维修人员接近发动机或进行只能在开车状态下才能进行的调节工作。

Only under the test person?s command, maintenance persons are allowed to go close to the engine or perform the adjustment that engine operation is necessary.

3. 在一台发动机开车时，另一台发动机上禁止进行维修和排故工作。

Maintenance and trouble shooting work on the engine is forbidden when another engine is running.

4. 禁止任何车辆及人员进入危险区域。

Any vehicle or people are forbidden to enter the danger zone.
