What type of sound should be reported to the Captain in the event of a suspected tailstrike?

When it comes to identifying a suspected tailstrike during takeoff or landing, the sound that should be reported to the Captain is a screeching or loud bang. This type of sound indicates a significant impact or contact between the tail of the aircraft and the ground, which often occurs if the aircraft’s angle of attack is too high during landing or takeoff.

A screeching or loud bang is typically characterized by an abrupt, intense noise that can signal a serious issue requiring immediate attention. Crew members are trained to distinguish these types of sounds as they are critical for the safety of the flight, prompting the Captain to investigate further and take necessary precautions.

The other sounds listed, such as sizzling, thumping, or buzzing, do not generally correlate with the specific conditions and consequences associated with a tailstrike. While they may indicate other issues, they are not definitive indicators of this particular scenario and thus are not the priority to report in such cases.
