BIK 116.8. Right on. There should be no shame in being a co-pilot - first officer - second in command - second dickey -co-joe, or whatever.
This desperate avoidance of being perceived as a lower being than a captain seems to have crept in over the years. One sees it in GA where the first thing a newly "graduated" CPL holder does is to dash off to the pilots shop and buy two or even three gold stripes.
In the old days (deep sigh....) we often had NCO pilots called Sergeants flying say a Lincoln or a Dak. One was known as the pilot and t'other was called the second pilot. Nowadays one hears of the "Commander" of a Cessna 150.
Exits hastily stage left....
