GS out = 275 kts

GS home = 432km/h

PNR = ?

One for the charter pilots out there.

Answer 1

432km/hr = {[(432)(5400)]/10000} km/hr ≈ 233 kts.

Irremeable point at around 820 nm.

Answer 2

PNR is a term meaning "Passenger Name Registry".  This is a computer supported manifest of passengers traveling, scheduled to travel, those that have reached destinations, etc.

I do believe it is a term in the "stock market" as well but do not know how it is used.
