And so should there commanders.
Perhaps because of the awesome responsibility weighing heavily upon the epauletted broad shoulders of the data input processor in the left seat of a mega-jumbo, the rank of "Commander" does not do justice to the position of authority he/she holds. After all, there are four bar commanders flogging light singles around the skies as CFI's. .
Suggest the rank should be upgraded to "General" and his chum in the RH seat a "Co-General". That would distinguish them quite rightly from the lower classes of airline pilots.
Of course we could also go back to original ranks of just Pilot and Second Pilot. Nothing flash - but just a plain statement of our job.
