Jay2: I hope you don't mind, but I have to disagree.
Wires are THE issue for HEMS drivers. NOTHING takes precedence during an approach NOTHING. Not radios, not press on itis. It's all down to crew preparation.
I remember as if it was yesterday, the brief we used to conduct:
Hi level cct. Low lvl cct. 5 x S's and shoot the approach.
No radio comms allowed.
Everyone eyes out.
First to spot wires MUST route them. If he/she can't route the wirtes, abandon the approach.
300 hems missions.
NO close shaves.
Hitting wires is a failure of human factors/CRM unfortunately.
