Although the equipment list mentions a rad alt - it doesn't mention if there are 2, one for each pilot or if there are bugs with attention-getter lights and/or an audio alarm for low height.
What are the rad alt setting procedures in this operation?
Departing on instruments in those conditions sounds as hazardous as departing from a ship in the dark without NVG - extremely easy to become disorientated in the low-speed instrument environment.
