3 Terms and definitions

QX/T 151 and the following terms and definitions apply to this document.

Aircraft rain enhancement operations Use operating aircraft and airborne operating equipment to sow catalysts in the clouds to promote precipitation flying activities.

Airborne operating equipment Equipment for carrying out tasks such as air-to-ground communication, atmospheric detection, and catalyst dispersal during aircraft rain enhancement operations.

Air-to-ground communication system the equipment used to realize voice calls and data transmission between the operators on the aircraft and the ground commanders.

Atmospheric detection equipment the equipment used to detect meteorological elements is installed on the operating aircraft.

Catalyst spreading equipment the equipment installed on the operating aircraft to spread the catalyst into the cloud.

Work materials

A catalytic material that is sowed into the cloud to change the physical development process of the cloud and achieve the purpose of artificially affecting the weather.

Macro recorder

Personnel responsible for recording flight, operation and meteorological observation information during aircraft rain enhancement operations.

4 Basic requirements

5 Prepare in advance

5.1 The operator should submit an application for operating airspace to the relevant flight control department, and only after approval can apply for a flight plan.

5.2 The operator should submit a flight plan application to the relevant flight control department, and the operation flight can only be carried out after approval.

5.3 The operator should fully study the aircraft rain enhancement operation plan with the unit that organizes the aircraft rain enhancement operation.

5.4 The operator shall negotiate the division of tasks and job responsibilities with the unit that organizes the implementation of aircraft rain enhancement operations.

6 Direct preparation

6.1 Before the operating aircraft takes off, the captain should consult with the unit that organizes the aircraft rain enhancement operations.

6.2 The crew shall conduct pre-flight inspection of the operating aircraft and report the inspection to the captain.

6.3 The on-board operating personnel shall inspect and debug the on-board operating equipment to ensure the normal operation of the equipment.

6.4 Before adding operating materials, the operators on the aircraft should check whether the packaging of the operating materials is in good condition and within the validity period.

6.5 The pilot and the personnel on board should understand the relevant conditions of the take-off and landing airport, airspace and the latest meteorological information, and provide information when necessary.

Proposal to modify the operating route.

6.6 When using a non-pressurized operating aircraft to carry out operations, the operator should prepare portable oxygen supply equipment and warm and cold supplies.

7 Work implementation

7.1 Under the circumstance of ensuring operational safety, the captain should carry out operations in accordance with the approved flight plan and operation plan.

7.2 How to operate the operating aircraft should be decided by the captain based on factors such as airworthiness standards and meteorological conditions.

7.3 During takeoff and landing of the operating aircraft, the meteorological conditions should not be lower than the minimum operating standard of the operating airport.

7.4 During the taxiing, take-off and landing phases of the operating aircraft, the personnel on board the aircraft should fasten their seat belts.

7.5 Aircraft rain enhancement operations should be carried out within the operating airspace and operating time limit approved by the relevant flight control department. During operation, received flight when the regulatory authority issues an instruction to stop the operation, the operation shall be stopped immediately.

7.6 The flight time of an aircraft operating in a non-pressurized cabin is more than 30 minutes at an altitude between 3 000 m and 4 000 m, or at an altitude when flying at a temperature higher than 4 000 m, the pilot and the crew on board should use the onboard oxygen supply equipment.

7.7 During the operation, the crew on board should maintain communication with the ground commander through the air-to-ground communication system.

7.8 During the operation, the macro recorder should fill in the macro record form of the aircraft rain enhancement operation.

7.9 The ground commander shall combine the flight information, operation information, atmospheric sounding information and real-time ground monitoring conditions returned by the operating aircraft.

Closely track the evolution of the operation target cloud and promptly remind the crew to adjust the flight route.

7.10 Operating aircraft should avoid areas with severe weather such as lightning, strong convection, and freezing rain.

8 Post-processing

8.1 The personnel on board the aircraft should record the amount of operating materials used, and save the aircraft rain enhancement operations and meteorological observation data.

8.2 The operating personnel on the aircraft should recover and properly dispose of the remaining operating materials and residues.

8.3 The personnel on board the aircraft should inspect and protect the on-board operating equipment.

8.4 The maintenance personnel shall conduct a post-flight inspection of the operating aircraft.

8.5 After the homework is finished, the operator should comment and summarize.

9 Emergency treatment

9.1 The operator shall formulate an emergency response plan, clarify the division of responsibilities, response procedures, emergency measures, training and drills and other requirements.

9.2 The operator shall organize an emergency drill at least once a year.

9.3 In the event of an emergency, the pilot and the crew on board shall handle the emergency according to the emergency plan.

9.4 In the event of an emergency, the crew on board should follow the command and arrangement of the captain.

9.5 The operator should be equipped with oxygen supply equipment, fire extinguishing bottles, life jackets, first aid kits and other relevant emergency rescue equipment on the operating aircraft.
