JT -- I was just trying to correct an erroneous statement. Didn't mean to imply that "blind compliance" with the rules is always the prudent thing to do. On the other hand, if you can't follow a track within a 200 foot half-width until the end of the TODA, maybe piloting isn't your strong suit.
Popay and JT -- I wasn't trying to point out any kind of a problem with turns -- just being complete as far as what the rules require. Certainly turns before the runway end are rare, but they may be appropriate (especially over clearway) in certain circumstances.
