Any other "single pilot" aircraft no co-pilot time loggable.
Tank,
I don't believe that's the case. There are plenty of ops manuals out there with approved multi crew procedures for single pilot aircraft, including checklists and standard calls etc. If its approved by CASA the copilot can indeed log it. Take the Kingair for example, a single pilot aeroplane regularly operated multi crew and you can even get a copilot endorsement!
