The effect of this class of drugs is to remove anxiety and reduce the abiliity to assess risk and rationalise actions. It also reduces muscle tone and slows reactions. It can cause profound drowsiness.
Personally I wouldnt go near a plane if I were on any of these drugs, and we specifically avoid these drugs in our pilots even when they are not expected to fly for several weeks
Sorry
Ahh, no. On a proper dosage you will have more clarity in thought, be less distracted. The only thing I agree with is drowsyness during long boring flights, but I doubt there is a single person here who has not experienced this. Long term usage can cause short term memory loss (forgot to add that to my last post) hehe.
