The book said that ejecting is the correct action when the plane is “unresponsive to the pilot’s commands“. This simple, straight forward statement turns out to be more ambiguous than they intended. Do you eject if the radio doesn’t change channel? No, that would be silly, even though the plane didn’t respond to your command to change the channel. The plane is still flyable without the radio! Common sense says that you should just land and get the radio fixed. There’s even a whole procedure that pilots have to memorize about how to land at an airport safely even if you have no radio.

In this case the pilot changed from mode 4 (SVTOL for landing) to mode 1 (normal flight) when the ILS system went offline. But because the HUD blinked on and off several times, he didn’t realize that the plane was actually transitioning back to mode 1. He didn’t wait long enough for it to finish, and without his HUD he thought that the plane was unresponsive, so he ejected. But the plane was still flyable, even if it had actually been stuck in mode 4! You probably can’t dogfight in mode 4, but you can certainly fly to your alternate airport and land.

So instead of penalizing him for following his training to the letter, they changed the manual to state that ejecting is the correct course of action if the plane is unresponsive to the pilot’s “pitch, roll, or yaw commands” specifically.
