Hi
We were to do a series of flights between Kano and Jeddah. A course (c) of 072 or 252 degrees usually gave us a single heading flight for many hours (boring for the A/P, which did not complain), joining a sensible base leg at Jeddah or an excessively long Finals at Kano. A following year a different route was prepared which was 117nm. longer. Any NDBs were unreliable. We used the shorter route and Astro as before.
Any fuel saved enroute should be valued at destination price as it reduces the next uplift.
(Subsequent checking with the Air Mileage Handbook showed that the direct route was 3 NM. shorter than G.C.! It had been measured very accurately between the Standard Latitudes of a Lambert's Projection. Nobody had noticed!)
