What should be done if a heavy jet requires greater than normal taxiing power?

• A. Authorize immediately
• B. Avoid the clearance
• C. Notify ground control
• D. Cancel the take-off

Answer: (B)

A heavy jet requiring greater than normal taxiing power indicates that there may be a potential issue with the aircraft, such as an engine problem, brake malfunction, or other mechanical concerns. The appropriate response in this situation is to avoid granting immediate clearance for the aircraft to continue taxiing. This allows for a thorough assessment of the situation, ensuring safety considerations are prioritized.

By not providing clearance at that moment, it enables ground control and the flight crew to evaluate the aircraft's condition. Safety protocols dictate that if there are indications of difficulty, it’s crucial to address those before allowing any further movement or operations. This avoids the risk of the aircraft becoming uncontrollable or causing an incident on the taxiway.

Other choices do not adequately prioritize safety protocols under potentially hazardous conditions. Therefore, avoiding clearance is essential in this scenario.
