K8 aircraft

Karakoram-8 (K-8), Basic Cum Advance Jet Trainer, is co-developed by Aircraft Manufacturing Factory (AMF), Pakistan Aeronautical Complex, Kamra, and China Nanchang Aircraft Manufacturing Company (CNMC). The aircraft is being used for imparting basic and operational jet training to newly inducted pilots at PAF Academy Risalpur. Its key features are:

  • Wide speed range and high maneuverability
  • Satisfactory flying qualities in accordance with the requirements set forth in MIL-F-8785C IV for highly maneuverable aircraft.
  • Good field of view and cockpit arrangement very close to a combat aircraft
  • Advanced turbofan engine with low specific fuel consumption and minimum operation and maintenance cost
  • State of the art equipment (including instrumentation, communication, navigation, etc.) satisfying the requirements of training pilots for the future
  • Highly reliable escape system
  • Advanced strap on environmental control system capable of providing cockpit air- conditioning both on the ground and in the air
  • Hydraulically operated wheel braking and nose wheel steering
  • Multi role capability for training
  • 8000 flight hours service life for airframe structure
  • Long endurance and high service ceiling adequate for a wide range of missions
  • Low life cycle cost
  • Short turn-around time and low maintenance work load

Can carry a variety of unguided rocket pods, gun pods and small bombs on the wings. a larger gunpod can be mounted on the belly.
It has been shown with PL2 AAM on the under wing pylons as well, but how they plan to fire it without an FCR is beyond me. :)
