（ 5 ） Guardrail: The ladder and platform are equipped with necessary safety guardrails, with a height greater than 1.05 meters. The railings are made of strong, durable materials and can withstand the horizontal load specified in the load specifications.

3. Slide system

The slide system consists of a slider ( 12 units), sliding track, and support frame and other components .

（ 1 ) Slider: The slider consists of a rolling part and a suspension part. The rolling part is inserted into the track, and the rolling wheel contacts the track. The suspension part is connected to the trainee's safety harness.

The slider is required to be strong and lightweight, with a carrying load greater than 850 kilograms, The slider uses a four-wheel (with built-in bearings) structure to ensure smooth sliding on the sliding track without any obstacles. After reaching the landing point, the slider can automatically disengage, separating the trainee from the slider to prevent personnel collisions. It can also be disengaged at any position according to training needs. 。

（ 2 ） Sliding track: The sliding track uses carbon steel material. The track structure uses I-beams, " H " steel or other special steel. The sliding track is fixed to the track support frame. The error at the joint of each section of the track from the aircraft to the track tail is -1.5 to +0.5 , and the sliding track can carry 600 kilograms of dynamic load. The distance between the left and right tracks is greater than 1.7 meters, and the horizontal distance between the track and the column is greater than 0.8 meters, The total length of a single track is approximately 39 meters (± 0.5 meters (including the track extending into the cabin);

（ 3 ） Track support frame: The track support frame is a steel frame structure with a load capacity greater than that of the sliding track, and it can withstand the horizontal load specified in the load specifications (using necessary soft packaging and other safety protections). The columns use national standard round steel pipes or square steel pipes. The horizontal distance between the front and rear columns is less than 4 meters. The crossbar is selected according to the track connection requirements, mainly using I-beams or " H " steel.

4. Belt conveyor system

The belt conveyor system consists of a belt conveyor, power distribution system, and control system. The belt conveyor is installed at the rear of the cabin, installation height lower than the support platform 0.3 meters, and extends into the platform 0.5-0.8 meters.

（ 1 ) Belt conveyor: One belt conveyor is installed on each side after the tail of the machine exits the cabin. The length of the belt conveyor (distance between the centers of the rollers) is 10 meters (± 0.3 meters), and the width of a single belt conveyor is 1.2 meters (± 0.1 meters). The belt strength matches the training description requirements, with resistance to the impact of the trainee leaving the aircraft. The power of a single belt conveyor is determined according to the above training description and geometric dimensions.

The two belts are installed parallel to each other, with consistent speeds and synchronous operation. The motor uses frequency conversion control and uses 220V (or 380V ) AC voltage, The operating speed of the belt conveyor is frequency-adjustable within 0-2.5 meters.

Along the direction of the belt, each belt conveyor is equipped with transparent safety guard plates with a height of no less than 0.4 meters on both sides, The belt surface is bonded with 0.15 meters (± 0.02 meters) thick high-density ( 30D and above) sponge to protect the safety of the trainee when leaving the aircraft;

（ 2 ） Body protection: The belt conveyor is designed with protection. When not in use, it prevents the belt conveyor from being affected by wind, dust, rain, snow, and sun, maintaining its integrity (when not in use, it can be moved to the lower part of the cabin and protected).    ） ; A 100cm*200cm*30cm (±1cm) protective pad is laid on the ground at the tail of the belt conveyor.   

（ 3 ） Power distribution system : The belt conveyor is equipped with a distribution box, and the configuration of the distribution box matches the   power used, including but not limited to circuit breakers, current transformers, air switches with leakage protection, and other necessary electrical components that meet quality requirements;

（ 4 ） Control system: The belt conveyor control system mainly realizes the synchronous operation of the drive motor and emergency shutdown in case of training failure. Emergency shutdown devices are installed in the central control center (where the guardrail is placed) and on the side of the conveyor belt, adjusting the frequency conversion operation of the belt conveyor. The central control center can display the operating status of the belt conveyor, etc.;

5. Training effect monitoring system

（ 1 ) Monitor the time and interval of the trainee leaving the aircraft (the detection device has millisecond-level function). It can accurately report at the end of the training; the belt conveyor can be stopped in an emergency during training.

（ 2 The monitoring device uses an infrared reader for data acquisition, PLC processing and control;

（ 3 Training time description

①Trainees are divided into two columns, left and right, and take turns passing through the detection point during training (following the order of left 1 →right 1 →left 2 →right 2 …);

②Each training session must include at least 24 people. At the end of the training, the screen will display and the system will record and voice broadcast the total time taken for all personnel to leave the machine;

③At the end of the training, the screen will display and the system will automatically record and voice broadcast the personnel who took less than 0.2 seconds to pass through the detection point compared to adjacent personnel on the left and right.

（ 4 Monitoring data application

By recording, collecting, and saving relevant training data, it effectively evaluates the trainees’ training effectiveness and provides guidance for training.
