I was planning to practice low visibility AWLS approaches in Kutaisi but shortly after taking off and entering the clouds, I found that the HUD is basically unreadable despite brightness set to maximum.   
I am wondering how one is supposed to perform an "ALL WEATHER LANDING" when the most essential system, the HUD is unreadable.    
Did I miss some steps turning on / adjusting something or at the current state it's really this bad? If it's not something that I missed then I have to conclude that the Razbam Harrier is currently not certified for low visibility approaches simply because the HUD isn't readable under certain conditions.   
EDIT: 
I have checked the HUD of the Hornet in the exact same mission therefore same weather conditions, and the Hornet's HUD is perfectly readable. So it's the Harrier's HUD not yet up to standards, making it currently impossible to perform a proper low visibility approach despite the aircraft being equipped with AWLS - due to HUD readability.
