A 61.58 is essentialy an instrument excercise with the required pilot demonstrations documented by the FAA. If you completed this with CAE or FliteSafety they provide the client with paperwork itemising the actions performed, if it was completed in the aircraft then similar paperwork should have been generated. Whereas the FAA will accept that the 61.58 must have included the basic requirements, validations usualy require itemised documentation. Bermuda has tightened up its act after years of being slated as "just another flag of convenience".
