G450/G550 differences course - how often?
Hello all
A question for those of you with knowledge of FAA rules - out of this, I am hoping to find some references to CFR Part 91, or other suitable directives/legislation.
The Gulfstream G450/G550 models are covered by the GV type rating under FAA. Best I can tell from rumour/hearsay/PPrune is that difference courses between these two models are completed to satisfy company and insurance requirements, as opposed to formal FAA requirements. I am unsure of the truth in this.
Under Part 91, is there an FAA requirement to complete differences training on a regular basis, similar to recurrent training, in order to operate both models?
Thanks in advance for sharing your thoughts
