Avoiding / Preventing Whiteout

Recommended Posts

Hi,

 

For those used to fly in the pure white mountains with the famous flat light.

Has anyone any experience using color boxes designed only to put a colored layer on the snow for reference?

 

Someone said they use this in certain areas, both for Heliskiing and SAR when landing in areas with risk of whiteout.

 

Any experience and ideas appreciated for this application.

Ski stakes are always good if you have multiple landings and can get in there on a good day. When working in the mountains I always carry a couple of rocks with flagging tape to drop for a reference

Narrative: UPDATE / Add info from TSB: A11P0025: The Eurocopter AS 350 B2 helicopter, C-GBGT, operated by Slave Lake Helicopters was one of two helicopters conducting heliskiing operations for a ski lodge about 160 nm NW of Smithers, BC. A group of skiers had been dropped off and the helicopter was proceeding down, on the other side of the mountain ridge (due to localized and variable weather conditions) to the pick-up point. While en route, the helicopter encountered marginal VMC and attempted to descend through a break in the cloud. The helicopter contacted snow covered terrain and began rolling down the slope. The pilot, the only person on board, released his seat belt and was ejected as the helicopter continued to roll. The pilot was not injured. The helicopter received substantial damage. The on-board ELT (406) activated and was turned off by the pilot. There was no fire. The ski lodge utilized a GPS tracking system to monitor the heli-ski operations and was aware of an incident immediately. Rescue was accomplished within 40 minutes.
