Looks like some serious upgrades
Including AAR
http://www.livefistdefence.com/2017/02/ ... -hawk.htmlThe changes in the Advanced Hawk are significant. For instance, the Advanced Hawk sports HAL-led engineering tweaks to the aircraft’s wing — the addition of an active slat leading edge and an upgraded combat flap — which adds more flying envelope across the spectrum. Other changes, detailed in the schematic below, importantly include increased engine thrust on the Adour Mk.951, a smart weapons capability (which is probably why HAL has designated it the ‘Combat Hawk’ in internal communications), air-refueling and a brand new panoramic multi-display centered glass cockpit.
