Remaining tire tread depth management system

A remaining tire tread depth management system comprising:

• a remaining tire tread depth measurement device configured to measure a remaining tread depth of at least one of first aircraft tires mounted on an aircraft;
• a tire wear amount estimation device configured to estimate a wear amount of all aircraft tires mounted on the aircraft including the first aircraft tires;
• and
• a tire management server configured to estimate a remaining tread depth of all of the aircraft tires in accordance with measurement data output from the remaining tire tread depth measurement device and estimation data output from the tire wear amount estimation device,
• the tire management server including:
• an acquisition unit configured to acquire the remaining tread depth of the corresponding first aircraft tire measured by the remaining tire tread depth measurement device, and the wear amount of the corresponding first aircraft tire estimated by the tire wear amount estimation device;
• an error calculation unit configured to calculate an error of the wear amount of the first aircraft tire based on the remaining tread depth of the first aircraft tire and the wear amount of the first aircraft tire acquired by the acquisition unit;
• a first error correction unit configured to correct the error of the wear amount of the first aircraft tire calculated by the error calculation unit;
• a second error correction unit configured to correct the wear amount of the aircraft tires other than the first aircraft tire in accordance with a correction coefficient regarding the error corrected by the first error correction unit;
• a remaining tread depth estimation unit configured to estimate a remaining tread depth of all of the aircraft tires in accordance with the wear amount of all of the aircraft tires corrected by the first error correction unit and the second error correction unit;
• a number-of-times estimation unit configured to estimate a number of available flight times of all of the aircraft tires mounted on the aircraft in accordance with the wear amount of all of the aircraft tires corrected by the first error correction unit and the second error correction unit and a flight schedule;
• and
• a notification unit configured to notify a predetermined notification target of the remaining tread depth estimated by the remaining tread depth estimation unit and the number of available flight times estimated by the number-of-times estimation unit.
