New to Aerads, ACN/PCN
 

Here’s one for any that use the Aerad supplements.

If an airport is showing a PCN 32/R/B/W/T can a B767-300 use this airport?
(Unrestricted use)
For a 767 rigid pavement, medium, has an ACN of 51 at 172819 kg and an ACN of 20 at 87926 kg. Can I interpolate to get an ACN of 32, which would be 120782 kg; this would be the max weight for unrestricted use.

Any comments appreciated.

:confused:

I think I would make the same conclusion as you made.In our
company manual it says that our engineering department calculates the ACN but that a certain runway overload is allowed.
How much this is I have no idea. I assume this is done after making contact with the aerodrome in question. I will try to get back to you on Monday/Tuesday after I have had contact with the
pro's in my company.And by the way, we also use Aerad.

A/P Disc,

Thanks, appreciate your input.

:ok:

Hello Nollocks,

just spoke to the people who know more about
this than me and they say it is allowed to extrapolate and
interpolate with the ACN figures.So the calculation that
you made is correct.Don't know anything yet about
overloads being permitted.It turns out that this almost
never happens.If I know more about that I will get back to you.

Regards
