Karakorum - 8 (K-8) | Jet Trainer Aircraft
The export-variant K-8 Karakorum Basic Common Advanced Jet Trainer is co-produced by China National Aero-Technology Import & Export Corporation (CATIC) for export markets other than Pakistan, while later aircraft for Pakistan have been built by the Aircraft Manufacturing Factory (AMF), Pakistan Aeronautical Complex. The latest export variant is the K-8P version, which is operated by the PAF. The K-8P has an advanced avionics package of integrated head-up display (HUD), multi-function displays (MFDs) and comes equipped with MFD-integrated GPS and ILS/TACAN systems. It also has hardpoints for carrying a variety of training and operational bombs up to 250 kg, pod-mounted 23 mm cannon, and PL-5 / 7 /AIM-9 P launchers. In September 2011, NAMC produced another 12 K-8Ps for an undisclosed foreign client.

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
Technical Data
Power Plant
K-8 is fitted with Honeywell TFE 731-2A-2A modular turbofan engine with DEEC & hydro mechanical fuel control system.
Egress System / Escape System
Highly reliable escape system incorporating two Martin Baker MK-10L fully automatic rocket assisted zero-zero ejection seats to ensure survival capability within the entire flight envelope.
Cockpit Layout
Cockpit is designed to meet the latest Military Specification of Aircrew Station Geometry and vision requirements. EFIS made by Collins is fitted in front and rear cockpits. UHF/VHF communication system, TACAN/RADIO COMPASS & ILS are available as per the customers requirement.
Environmental Control System (ECS)
Incorporation of most effective ECS provides a roomy cockpit environment with air conditioning capability even on ground under an ambient temperature of -40 °C to +52 °C.
Fuel System
The aircraft fuel system consists of the fuel tanks and the fuel supply / transfer, vent/pressurization, fuel quantity measuring / indicating, refuelling and fuel drain subsystems.
The total fuel contained in two fuselage bladder-type rubber tanks and a wing integral tank is 2576 lbs.
The capacity of drop tanks is 428 lbs each.
