This will force Champ and Cub owners out of the air.
I can see the headlines now:

Spoiled antique airplane owners complaining about new safety requirments.

An easy solution is a blanket notam prohibiting flight without a working Mode C
transponder, for any area where UAV's are to operate.



Have you got a link to information about that?

Just wait until a UAV inevitably collides with an airliner, or a
runaway UAV crashes into a school yard. Then this issue will get some
serious attention.

General aviation has done both of the above, UAV's have not. (Yet)
Based on your argument I think we should immediatly ban General aviation!


Just saying over and over that the UAV has to do see and avoid is not going to make it
happen or make it possible. UAV's are just too capable and too attractive as technology to
go away, we need to start having a real discussion about what can be done to
coexist or we are going to loose.

Realize there are really two arguments going on here...

1)UAV's are too unreliable and thus dangorous.
I agree with this statement completly, however they will get better
and the reliability will improve. Be careful when arguing risks, arguing about
risks you don't understand or that are unfamiliar can easily lead us astray.
The world is not a risk free place, if you really are worried about your
personal safety then you outght to start working to ban teenage drivers
and old drivers for they kill far more people on a daily basis than any potential
UAV incident. Otherwise your comments just look reactionary.

2)UAV's must do see and avoid. This is just not going to happen.
They can do the equavalent with mode C transponders and
possibly the GPS survalince described in the link above.
