(d) has not less than 10 hours aeronautical experience as pilot in command of the aircraft type from which the descent is made. For high-wing Cessna aeroplanes, time accrued on the more complex types may be credited for the less complex types in accordance with Appendix 3 (of this manual); and
I think it would depend on the operator whilst the 172rg might be as / more complicated than the 182, when you have 6 bums & 2 loads of fuel she's quite different to the 172.....
Another thing to keep in mind is there are a few suped up 182's kicking around, ours has a 520 up front & wing tip extensions so you can run out of elevator real quick if you get it wrong
