“...the altimeter wasn’t set properly by the pilots...”
Has to be set to current barometric pressure EVERYTIME before takeoff!
“Has to be set to current barometric pressure EVERYTIME before takeoff!”
Yep, copter was at 300 feet at crash, altimeter was verbally reported by crew to be at 200 feet. At 200 feet, no collision.
For the non-aviators on the thread: The pilot, as part of their pre-flight checklist, checks the altimeter altitude against the known field elevation of the runway (or helicopter pad). Since they were that close to their takeoff point, it's unlikely there was much difference in barometric pressure from ATC and the altimeter setting from takeoff.
For this flight, temperature was not a factor where icing would affect the static tube feeding the altimeter.
