Now I am prepared to admit the wording is a little restrictive but let's take a look at effective operational length.
CAO 20.7.somethingorother
Corrected Effective Operational Length: A length of runway — including
over-run — expressed in feet, corrected for slope, runway surface, and
approaches, declared by CASA as usable for take-off or landing by a particular
aeroplane.
So here effective operation length includes overrun. It also makes mention of 'approaches'.
Effective Operational Length can include stopway and clearway for takeoff.
So is EOL always going to be = the actual length of the runway?
I think I've never seen a runway, grass or other, where the threshold was the beginning of the overrun.
So if a runway has an overrun (with clear 'approaches'
)...and most certainly do...I can be at 50' at the beginning of the overrun which is the beginning of the EOL?
So therefore the EOL is the distance between the point at which I pass 50' and the far end of the runway...and if that distance is equal to or greater than the LDR as found in the POH I am legal...and wasn't at 50' over the threshold.
I have looked and looked but can't find where Operational Length and Effective Operational Length are defined differently...in fact I find no reference to OL at all. References can be found to ground roll and clearly the rules deferentiate between that and distance which has a component which is airborne. No where does it say you must be at 50' over the threshold.
It would be an interesting point of Law
Out of interest what types did the fella operate from the 450m strip 'quite happily'? I don't think I'd be keen to take a PA28 into a 450m strip either but did the numbers say it was long enough EFFECTIVELY
I love thrashing this sort of stuff out
