Hi Frazzled; re your post #82.
Because the C-130 airframe is so wonderfully versatile, it is adaptable for a broad range of special operations roles. I have crawled over some such birds and they mostly require additional aircrew members to operate specialised gear and command missions. The larger flight deck of earlier model Hercules has been adapted in varying ways to provide additional crew stations with some also having modular units installed in the cargo hold.
I have not been on board the C-130J, but the reduced crewing and stretched cargo hold make it more like a civilian air-freighter albeit with short-field characteristics. When the 'J' model was being introduced to RAAF service, experienced Herc qualified friends commented that some black boxes had been repositioned to just above the ramp, somewhat impeding loading of higher gear for which earlier models had been cleared; but maybe that problem has been overcome.
Post-Air Force, I spent a decade in airline flight training when glass cockpit technology and computerised flight management systems were coming into vogue. Beaut stuff of course enabling crewing economies for airline operators; but the varying ability of aircrew to assimilate a whole lot of floating data soon became apparent. Not a problem in routine operations; but when the pressure comes on, some information that gets displayed is not always adequately absorbed.
These days, glass cockpit enhancements are available for most types of aircraft, but there seems some risk to me of overloading the ability of aircrew to stay ahead of the game in stressful combat roles, unless there are adequate crew members to cope with all of the essential information monitoring in addition to just driving the aircraft. Designing military aircraft flight decks around crewing economies is arguably not altogether wise.
RAAF C-130H would be eagerly sought and refurbished as necessary by other operators if discarded by the ADF.
