What might happen if the check of the controls before a flight is less that methodical?

If the pre-flight checks of controls are not methodical, it can lead to overlooked issues that compromise aircraft safety. This negligence may result in equipment malfunctions during flight, which could endanger passengers and crew. Additionally, it could lead to costly repairs and legal repercussions for the airline. Ultimately, a lack of thoroughness in these checks undermines overall aviation safety standards.
