What type of taxiing power should be avoided for heavy jets?

• A. Normal
• B. Greater
• C. Lower
• D. Excessive

Answer: (B)

The correct answer identifies that heavy jets should avoid using greater taxiing power. This is primarily due to the potential for excessive stress on the aircraft's landing gear and tires, which are engineered to withstand a set level of force during taxiing. Heavy jets are significantly larger and heavier than smaller aircraft, meaning that any extra power used during taxiing can lead to difficulties in controlling the aircraft's movement.

Additionally, excessive power can amplify wear and tear on the aircraft, increase the risk of damage to ground surfaces, and contribute to poor fuel efficiency. Using appropriate levels of power helps ensure a smooth, safe taxiing experience while minimizing these risks, particularly in crowded taxiways or on wet pavement where braking may be less effective.

In summary, limiting the taxiing power to normal levels is essential for maintaining aircraft integrity and safety, especially for heavier models that have stringent operational guidelines.
