Hi
I don't think the HUD
itself will be useful in the situation you describes.
The purpose of the HUD is to show parameters to the pilot who has his head up, allowing him to see outside in the same time.
At night, IMC, you don't need to have your head up, there is nothing to see out there.
What may be useful in the situation you describes is a velocity vector, or any other mean that shows the energy state of the aircraft.
An AoA indicator may help, too.
But none of those were required per regulation, nor required for the crew to be able to manage the situation they were in.
