PROBLEM TO BE SOLVED: To determine whether or not a tire having experienced a take-off avoidance can be further used.SOLUTION: A management method of an aircraft tire determines whether or not a tire having experienced a take-off avoidance can be further used, using a management device 10 of the aircraft tire comprising: a temperature sensor 11 for measuring a temperature of an air inside the aircraft tire or a part of the tire; recording means 12 for recording a temperature history of temperatures measured by the temperature sensor 11; determination value calculation means 14 for calculating a determination value which is a product of a temperature exceeding a predetermined determination temperature in the tire temperature history and duration time period thereof; and determination means 15 for determining that the tire cannot be used when the determination value exceeds a preset threshold value.SELECTED DRAWING: Figure 1
【課題】離陸回避を経験したタイヤが、以降に使用可能であるか否かを判定する。【解決手段】航空機用タイヤのタイヤ内部の空気温度もしくはタイヤの一部の温度を計測する温度センサー11と、温度センサー11で計測された温度の履歴であるタイヤの温度履歴を記録する記録手段12と、前記タイヤの温度履歴のうち、予め設定された判定温度を超えた温度とその持続時間との積である判定値を算出する判定値算出手段14と、判定値が予め設定された閾値を超えた場合に、当該タイヤが使用不可であると判定する判定手段15とを備えた航空機用タイヤ管理装置10を用いて、離陸回避を経験したタイヤが、以降に使用が可能であるか否かを判定するようにした。【選択図】図1
