surely the overriding need to ensure airline safety makes it a price that has to be paid.
You say the system is fine, I don't have the stats but it would make an interesting Freedom of Information request.
How many operating crew have been subject to testing under the "reasonable suspicion" that they have breached the RTA?
How many have been positive using the field equipment?
How many have later been proven not to have been over the effective zero limit?
How many have later been found guilty of an offense?
In other words are the procedures and equipment actually able to reduce the number of false positives to an acceptable level?
And does the risk we are attempting to prevent actually justify the destruction of reputation's of pilots and airlines that a false positive produces.
