I knew that would raise some eyebrows
The Navigator in this case would operate the master control of an automatic survey camera system, linked to an INS and DGPS with WAAS... Necessary for maintaining flight lines accurate to 25 - 50m at 7000ft and 110KIAS... The faster the easier actually, but the camera won't keep up LOL.
Navigator's function in this case is also the Mission Commander... where as long as we're not on the ground or in the take-off and approach phases, the captain can only intervene in weather and fuel aspects. (we annoyed a few capts that way... but some F/Os use us as paybacks to their Capts.)
Ever talked down your own plane using the onboard DGPS and INS below approach weather minimas? U'd loose your voice by the end of the approach and the ATC was impressed but scared to bits... I don't fancy doing that regularly again... even for Demos...
What next? Well, no plans for morse codes but we can carry a wireless (HF
radio) operator sometimes...
C130s still carry navigators (map, pencil, a couple of stopwatches and a strong throat)... Needed for low level "blind flying"... Now they're a different breed altogether!
