The issue won't be the aircraft, the airline, the training or the manuals, the issue will be caanz. The factory can issue you with AFM and POM that states your system can achieve +/- 0.1 Nm at all times and has terminal scaling and is suitable for all RNP types factory standard, but unless the Wellington handbrake brigade are satisfied for themselves (including the vast caa 24091/08 application form) and issue you with the appropriate 2129 radio station approvals, you can hurry up and wait like the rest of us!!!
