Narrative:

Arrival weather was reported below minimums with light rain. Just before holding fix weather reported improvement from 1 kilo visibility to 5 kilo visibility. We executed ILS. Runway lights visible at 600 ft AGL with moderate rain; smooth ride. Flare and touchdown and rollout visibility severely impaired by hgs blocking view of the runway; rain and dark hole conditions severely added to the problem. The hgs was far more impairment than help. The visibility was near 0 with runway lights barely distinguishable. Definite hydroplaning with maximum autobrakes and maximum reverse. First officer reported reasonable visibility on his side with no hgs. Rain with hgs is dangerous. Hgs is impairment in certain situations. HUD needs to be optional use. Rain repellant would be a huge help. Some are carrying their own bottle of rainex and applying it when expecting rain during approach. Great idea and a bottle should be available on all aircraft.
