See and avoid is part of the responsibility a pilot accepts when he turns a prop/rotor/turbine.

The rules allowing flight for some aircraft are for good reason. They do not have engine powered electrical systems, i.e. ;gliders, antique aircraft, hang gliders.

Unless you are in favor of outlawing those aircraft, it is going to stay that way until battery and radio technology makes it reliable and feasible.

Twice in the last decade I have personally had to take evasive action where a "child of the magenta line", was not looking outside.

The most recent was a low level go around where a 737 took the runway I was landing on,. (Yes he had clearance) and if he had looked outside before crossing he hold short he would have seen an aluminum overcast on short final.

The other time, landing at a small uncontrolled county airport where a charter Navajo rolled onto the runway in front of my 1939 vintage plane with no radios. Same thing, he didn't (see and avoid), look outside.

I confronted him the next day and his response was that he called traffic on Unicom and didn't hear anyone.

Put down your game/phone/iPad/Usatoday and say heads up. It is certainly no imposition.
