3.2.5. Drone training plan for departments

For machinery and equipment with strict safety requirements such as forklifts, hoists, cranes, oil heaters, elevators, etc., there are clear regulations on operating conditions and a specific list of machinery types. Therefore, the management, organization and training of these subjects is quite easy, without too many difficulties, because these subjects have specific and clear legal bases to rely on and apply. The content and training program for the group of subjects operating machinery and equipment requiring vocational certificates or machinery and equipment with strict safety requirements are available and can be easily trained and certified with full legal value by hiring a training service provider for workers. However, for the use of Drones, there are currently no specific regulations on the conditions of operators, as well as the certificates required to operate it. Therefore, if businesses want to use drones to serve

Construction supervision or any other field must develop its own training process and set standards for training employees to use drones at the company, to ensure a certain basis for determining the ability of employees to operate drones, as well as ensure safety, reputation and protect the company's assets.

Plan 1 : Register the safety department and other departments that need to use drones to participate in Drone control training courses organized by training service centers.

B1. Create a list of learner information. B2. Contact training service providers.

+ The service provider provides information about the instructor, the instructor's experience, training location, training time, training content, training plan, training facilities and sends a price quote to the company.

B3. Arrange study schedule for students.

B4. Issue flycam/drone operating card to those who complete the training course (valid for 2 years).

B5. Keep records of training course participants.

B6. Organize periodic training every 2 years for Drone users.

Plan 2 : Build your own training program

Step 1 : Choose a trainer

+ Trainer : People who have been trained to fly drones at a training service center, have a certificate of completion of a Drone flying course and have 4 years or more of experience using drones will be considered to become internal trainers for the company (Subsidy of 1 million/month).

+ Depending on the actual situation at the company or construction project, those who have taken the drone training course at the training center will meet and discuss and build a self-training program that is reasonable and suitable for the conditions at the project.

Step 2 : Build an internal training program

Based on the reality and conditions of the company, those who have participated and completed the flycam/drone training course will be gathered to discuss, contribute ideas and build reasonable content for the training program.

The contents of the internal flycam/drone training program must include:
