Summary of Defect:

1/ The FIS ASE should abort the dialogue when a D-START indication is received with a Calling Peer ID which is not valid for the expected peer originator end system type of the D-START message.  
2/ The reception of a D-START indication with a FISDownlinkAPDU in the User Data parameter should be allowed only for the FIS-ground-ASE.
2/ The reception of a D-START confirmation with a FISUplinkAPDU in the User Data parameter should be allowed only for the FIS-air-ASE.

Upon receipt of a D-START indication with the <UserData> parameter containing a FISDownlinkAPDU [FISRequest] APDU and the D-START Indication application service priority parameter has the abstract value "Aeronautical Information Service messages" and the RER Quality of Service Parameter has the abstract value "low", then:

To:
