Reading this stuff here got me to wondering who can be considered a flight instructor.
Can someone like me call myself a flight instructor even though my rating expired many moons ago, or do I need to go through the mind numbing process of renewing my flight instructor rating to be considered a real instructor?
There that should bring out some real interesting ideas and opinions.
Of course you can, and from what I've been reading from your posting you are doing just fine for an "old retired guy" :-)
I've been retired from active flying as an instructor for a long time now. Lost my medical some time ago.
I've remained active in the community as a safety advisor and consultant both in primary instruction and specifically in the aerobatic display community.
I still consider myself very much an instructor and I'd like to think that I'm considered as such by my peers as well.
So far at least, this has been the case.
By all means, stay involved. GOOD teachers and CFI's are always welcome in the safety community whether currently flying or retired.
