Anyone who has been flying for a while will have noticed that the younger generation of glass cockpit helicopter pilots spend far more time with their eyes inside than outside. Programming the FMS, selecting various displays and auto-pilot functions are but a few distractions. They rarely have to fly manually these days so seem to have to find things to do. Now we have introduced the iPad into the mixture.
Add to that more traffic and - TCAS or not - I fear that mid-air collisions will become far more common.
