Following full size standards & practices
Full-size flying training is totally structured, there is an overall training program & individual sorties are formed to meet that program. Each sortie is planned & then briefed. The sortie is flown as per the brief, followed by a debrief, highlighting good & areas which need attention. The next sortie is then planned to continue towards the overall training program.
Model Plane Training follows the same training ethos.
Although, sometimes, even full-size flying organisations break those rules!
