The invention discloses an ACARS message analysis method suitable for an airplane. The message analysis method comprises the following steps: receiving an ACARS message signal under a VHF data link; determining initial code element information according to the synchronization character of the ACARS message signal; demodulating the ACARS message signal into an MSK signal digital sequence by adopting a digitalized demodulation method of the MSK signal; converting the MSK signal digital sequence into an ACARS signal coding sequence according to a decoding conversion algorithm, wherein a first element of the MSK signal digital sequence is determined according to an initial phase. According to the ACARS message analysis method suitable for the airplane, the mature MSK signal demodulation methodin the technology is ingeniously utilized to analyze the ACARS message, implementation is easy, a high-speed processing chip complex in design does not need to be used, and the cost needed by ACARS message analysis is remark
