Interesting discussion. I'm not a pilot, nor do I play one on TV. All I can offer is that there might be some less common professions out there that even a surgeon might not be super familiar with. Presumably, if they didn't know the types of activities in the profession, I would hope that they would ask the patient and maybe even go through some of the physical movements in front of the doc pre op. I think the detail of 30 lbs pushing on one leg for ....minutes is excellent info that would give a surgeon and even a very experienced PT the kind of info they would need for helping you get the best recovery possible.
Also, the surgeon and your employer will probably be rather conservative on the return-work form if you are claiming sick leave under FLMA (US). I'm a desk jockey so the worst I could do would maybe slip when I'm getting my 5th cup of coffee at the coffeer bar, and bust up my my new hip, then sue. I wouldn't do that though. For a pilot I think the stakes could be just a touch higher so I'd like to think that the surgeon would be conservative about return to work/full activity and the patient would be, just that, patient.
BTW - I'm not a good example of patience, I drove before I should have, so maybe I'm not the guy to ask.
