Thank you guys for your inputs. Actually I wanted to know how the issue of safety pilot is considered globally. Yeah I found that FAA accepts it when practicing IR and JAA forget it. But in philippines CPL holders fly with PPL holders on Single pilot certificated airplanes and they both log and I don't know how they do it and if it is acceptable to their aviation authority but I have seen guys doing it. but then the funny part is even if you have a plane rating on your CPL but do not have it on your FI license you can not instruct on that despite it comes under same class and category.
