In addition, nighttime TOW firing. Unless you can teach a crewman to high hover on goggles (difficult) while you go through the launch sequence, the you'll have to trust him with the engagement. Without sounding unfair, I do not think I could do that.
Actually you put the Aircrewman/ gunner in the LHS and let him fire the missile, he was highly qualified to do so, and his recognition skills were excellent. He could also fly the aircraft. This was the norm before the AAC changed its policy to 2 pilots in preparation for the AH programme. Being honest hovering on goggles is not that difficult.
The Navy do fly single pilot SK on certain sorties, but not on very demanding missions as the battle-field is too busy. Allied to the fact that the crewman is often manning the GPMG, navigating or handling troops and or stores.
