Default Re: You have your choice of weapons to go to war with

The elapsed time of the F-22's maneuver would be much shorter/quicker than the 172's. However, the distances involved are significantly greater. Though it's roll and pitch rates are exponentially faster than the 172's, it covers far more airspace when executing direction changes.



In an emergency evasive maneuver, time is irrelivant. What saves your ass is being able to stop shorter, or move the placement of your vehicke over the shortest possible distance. I still assert that the 172 will maneuver in a significantly shorter/smaller box than an F-22.

I think if you asked any fighter pilot that same question, you'd get the same answer.



Of course if I was wanting to use an aeroplane to avoid a traffic collision, I'd take an Extra 300S every time. -Sean

Well, I currently can't take your advice about a pilot due to being surrounded by 'copters. But I crunched some numbers and came out with this:



Raptor est Turn Radius about 600m

Cessna 172 about 600ft (per performance graphs)



What can I say, my bad, I admit defeat. On a side note, as you agreed, the F-22 completes the turn much faster. (At least give me that much without the actual numbers, I can do the math but time to go back to the tent...)

And, you could bet your bottom dollar that some of us (though, certainly not me) would use it for down-load porn, so they can strengthen their wrists.

Motard bike would be #1 in the trenches as far as motorcycles go. Of course, skill and experience far outweigh ANY motorcycle advantage. Didn't KPyle state that he quit commuting after nearly getting run over recently? Sounds like his 600 scares the shyt out of him, and now he just sits it in the garage and brags about it. I have more respect for somebody that rides their scooter every day, than some internet loudmouth that doensn't ride any more.

And a 650 V-Strom being as ugly as it is, nobody will steal it either! Good choice for an all-around sreet bike though.

Default Take it easy, Sean...

Easy, Sean...Nobody, can get to a defibulater quick enough, for you to be agreeing, much, with Kpaul.

I'm not fighter pilot, but I can do some basic math:



THis questions primarily depends on speed. A C172 stalls out around say 35MPH (30ish knots) in straight and level - say 50MPH (45ish knots) for a 2G (60 degrees of bank) turn, although there's not a lot of room for error there (I think you're getting awefully close to the AOA limits and might be through them).



An F-22 can likely sustain 9Gs+ or so, but even at say 330 mph (I'm assuming that the F-22 doesn't do real well at low speed given it's high speed characteristics), your 172's going to turn inside it. The formula is simple:

a=v^2/r



In this case, for the Cessna, a ~ 1.7g (2 is normal to the plane of the aircraft) and v ~ 73 fps, so r ~ 100 feet - a very tight circle.



For the F-22, a ~ 8.9g and v ~ 484 fps...uh oh...we're going to hit that cliff...wish we had our Cessna... r ~ 817 feet - a much, much bigger circle, although still remarkable in its way.



Kpaul's analogy is nonsense, by the way, because of the way of airplanes versus ground vehicles. Ground vehicles can, duh, stop, and can turn at their minimum radius at close to zero speed. Aircraft are different and can actually support a shorter radius at speeds above minimum straight / level stall speed (otherwise you'll stall, and in a turn, this can make bad things happen because one wing will stall first spin spin spin crunch).
