There are no plans to give it a mid life upgrade
TC obviously has a direct line to LT.
Anyway our crew happy this year with 206 to 207 engines, extra 250lb of (public transport) payload, nvg cockpit, trakka beam spot, improved aircon, improved eng intake filtration and active NACA doors (volcanos?), extra 200 lb(below floor)fuel tank....and tinted windows!
All usual 'add-ons' - (talking 'range bearing height' TCAS (brilliant
), integrated moving map, extra strobes, chelton airwave)-now housed internally, no belly pod, giving extra, rough ground, landing clearance;
