The present invention relates to a method for detecting performance of a fuel unit of an aircraft auxiliary power unit (APU), comprising: obtaining APU messages at multiple time points within a time period; obtaining running parameters of the APU fuel unit according to the APU messages, the running parameters at least comprising starting time STA; calculating average value AVG and deviation index δ of the starting time STA within the time period; and determining whether performance of the APU fuel unit is in the stable phase, decline phase, or failure phase according to the deviation index δ. |
