Answer 19

squawk code

Question 20

What can Mode C transmit

Answer 20

current pressure altitude to the ATC - required in some control zones in canada

Question 21

What are Mode S transponders designed to do

Answer 21

help ATC in busy areas - allow automatic collision avoidance

Where is Mode S mandatory

Answer 22

in controlled airspace in many countries

Question 23

Why in general aviation have there been objections
