boeing runway extension 14.2 miles

[Captain Greaser]

Can anybody tell me why it is 14.2 miles? Why was this distance picked?

[Check Airman]

I suppose somebody just liked the number 14.2...


Thanks for enlightening me. I was under the impression that it was a mere 14nm.

Convert it into feet and you should find that its the same as the distance used on a "TYPE A" aeronautical chart.
