Personally, I've now been flying for over 14 years with over 5000 hrs & have never seen a signal gun in real life. I currently fly as a regional airline FO and have no problems using PAPI or flying at night and pass regular simulator checks to the same standard as colour normals. However, due to the CPL restriction, I am prevented from obtaining a command despite the fact I hold an ATPL. There are a quite number of other very experienced pilots here in Oz too, all in similar situations and all with exemplary safety records who face the same dilemma. These are the ones Arthur Pape is again passionately working with to assist this time around, as well as our friends overseas too.
That's really a bit rough. I thoroughly back up what you are saying also having no difficulties night flying. I do get worried about some folk I fly with who supposedly have normal night vision, having had to offer advice more than once to avoid them making a big hole about half a mile short of a runway. I hope things gets sorted for ATPLs because its just not on to stop them progressing in their trade on the basis of ths very spurious rule.
