Thanks for the input...I should have been more descriptive in the situation.
Lets talk about Iraq/Afghanistan. The operators do not have a local 135 certificate that I am aware of. They do exclusive work with the Dept of Defense or the State department and do not hold themselves out to the general public. They do hold an FAA 135 Certificate and operate according to that certificate and their OPs Specs. Specifically does the ICAO age 60 rule apply? Are they involved in an International Commercial Operation? Can two pilots over the age of 60 fly together?
I am not as versed in this as maybe I should be, but I would think that ICAO is designed for International operations, and that "could" be defined as transporting person or cargo for hire across international boundries. In order to work within the boundries of a foreign country, it would seem that the foreign countries regulations would hold supreme as all of the operation is conducted within that country and no "international" operations are taking place.
I agree that the aircraft and crew are not operating in the country of the aircrafts registration, and are operating in a foreign country. But does that actually mean "International Operations"? I realize that this could be considered an exercise in semantics, but isn't that what rules and laws are?
