AIRCRAFT


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

Technical Data

Power Plant Egress System / Escape System
K-8 is fitted with Honeywell TFE 731-2A-2A modular turbofan
engine with DEEC & hydro mechanical fuel control 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 Environmental Control System (ECS)
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.
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.
