@Farhan or someone with more rep than me: aviation.stackexchange.com/questions/11807/… does need an edit (the OP mixed up the DC-8 and the DC-9 and that got missed when Farhan edited it -- but I don't have the rep to make an edit that small)
@Farhan One possibility is breaking the answer in half at the picture. One question about how circumnavigation is defined, another about how people actually do it.
I do think that leaves the first part a bit sparse and the second part still very broad. Maybe you could include some typical routes or something in the first part.
When I first saw the title I thought it was like a marathon flight or something to break world records.
Then the routes... depending on which countries the flyer pick, airplane endurance and perhaps political situation of that area, I'd say it definitely varies
Suggestion....well, "what is circumnavigation" is a good topic on its own; regarding "how do pilots circumnavigates", I agree with @fooot it's still too broad.
I think if we fill only a few people in the A380 we should get pretty close (-: If we can remove the seats and replace them with cabin fuel tanks, even better.
@rbp Re: this comment, I thought the regs only required a placard if you take off. As best I can tell you can taxi around all day long with busted equipment & no placard…
@voretaq7 i think that's what 91.213 says, yes, but i would not want to be the one who noticed the malfunction and scrubbed the flight, didn't placard it, and it failed in flight for the next guy
@rbp Agreed - I would put a sticky note on it too in case the plane was dispatched later before the gyro could be fixed so whoever got it knew there was a problem - but it's not required until you take off.
I'm picky about stuff like that because we have so many people bitching about how the FAA is all up in their bizniz, but half of the stuff they've convinced themselves is required is just stuff they've heard and taken as gospel :)
like the "I won't declare an emergency! I don't wanna have to do all that bloody paperwork!" crowd
i didn't go into the next level of detail, but you can turn the engine off in a heli, and while they blades are still turning, pull up on the collective and roll the aircraft over
@voretaq7 I thought you were being extreme about that, but I flew a heli in X-Plane and the L/D was negative. Probably because of how it's calculated. But still. Madness.
