Study Notes

Precis of Contemporary Technologies

The information in this document is not for press release or unauthorized distribution.
The document is about a course on Contemporary Technologies for Airmen Leadership & Supervisory Course at the Airmen Leadership Academy, Pakistan Air Force.

Foreword

The Air Staff established the Airmen Leadership Academy (ALA) as a center of excellence to produce leaders.
This was achieved by merging the JCO's Academy and Professional Training Department into the ALA.
The ALA aims to equip personnel with leadership and management skills, refined work ethics and futuristic requirements of the Pakistan Air Force (PAF).
PAF is a technology-oriented service, where maintaining fighter aircraft requires a profound knowledge of contemporary technologies and reskilling.
The course at the ALA is designed to enhance the innate skills of Senior Non-Commissioned Officers (SNCOs) who are already serving in their trades.

Approval of Precis

The précis of Contemporary Technologies for the AL&S Course for Airmen Leadership Academy, PAF is 8 weeks long.
