FedEx’s call of “on the go” is clear to me? It means he’s executing a go-around. It’s common terminology, perhaps a carryover from the US Military, because we said it every time we executed a go-around, curious what you would prefer he say? As far as an undisciplined culture, that’s your opinion. How’s the air at the heights you dwell in?
Why not stick to standard ICAO phraseology? Fedex XY going around?
