What is the consequence of not maintaining the mandatory clearance between the aircraft and the deicing truck?

Maintaining the mandatory clearance between the aircraft and the deicing truck is crucial to ensure the safety and integrity of the aircraft. If this clearance is not adhered to, the deicing truck could potentially come into contact with the aircraft. This could lead to physical damage to sensitive aircraft components or surfaces, such as the wings, engines, or fuselage. Damage could compromise the integrity of the aircraft and possibly lead to more significant maintenance issues or operational hazards. The requirement for clearance is therefore a critical safety protocol to protect both the aircraft and its passengers.

The other options do not accurately reflect the importance of maintaining this clearance. For example, stating there are no consequences overlooks the real risk of damage that could occur. Also, while increased deicing time could be a byproduct of mismanaged operations, it is not the primary concern or the most immediate consequence. Finally, describing the operation as illegal would misinterpret the regulatory nature of safety practices; while proper protocols must be followed, the focus is on safety rather than legal ramifications alone.
