Further to Shagpiles post, the gps units planned to be fitted were actually purchased!! There were approx 100 shiny new G430 units acquired around 2006/7. So far as i know they're still sitting in a warehouse somewhere waiting .....so the project Shagpile speaks of already happened.
The dispute came down to cockpit layout, pilots v contractors and then who would maintain them.
Anyone know if PC21 comes gps eqquipped? Or is it another MRH90 'fitted for but not with' scenario?
