THE F-S HUOWAC. TACTICAL SUPERIORITY

THE F-S HUDWAC_ NOW THE PERFORMANCE OF THE F-S WITH

THE ADVANTAGES OF AN ADVANCED HEAD UP DISPLAY/WEAPON AIMING COMPUTER_

Today, fighter aircraft must be prepared to operate in an increas­ingly sophisticated tactical com­bat environment.

In both the air-to-air and surface-to-air arena, rapid advancements in technology, especially in electronics and guidance systems, have quickened the pace of avionics obsolescence in a number of highly capable combat aircraft with years of airframe and engine life remaining.

THE FIRST PRODUCTION HEAD UP DISPLAY/ WEAPON AIMING COMPUTER FOR THE NORTHROP F-S TIGER 11, GEC Avionics F-5 HUDWAC is now in production, making it pos­sible for the first time, to com­bine the excellent performance

and maneuverability ofthe

F-5 with the advantages of an advanced Head Up Display and

. Weapon Aiming Computer. DeSigned to be retro­

fitted into all F-5 E and F con­figurations with no structural modifications t o the airframe, the system is a cost-efficient means of upgrading the air­craft's com bat capabilities in a wide range of tactical sitllations.

THE F-S HUDWAC DECREASES Plwr WORKLOAD WHILE INCREASING WEAPONS DELIVERY ACCURACY. By presenting both flight perfor­mance and tactical data within

the pilot's normal field of view, the F-5 HUDWAC increases his sit­uational awareness, thus increas­ing survivability and improving mission performance.

,. MIL STD 1787 sym-bology is presented in a format which is easy to use, and is tai­lored to the aircraft's tactical situation. The system's digital computer provides continuously updated, real-time aiming solu­t' ?nS for a variety of weapon configurations, resulting in sig­nificantly improved weapons delivery accuracy.

I n fact, operational demonstrations have revealed dramatic air-to-air superiority over F-5's equipped with exist­ing electro-mechanical sighting systems, while air-to-ground accuracy was improved by a

factor of better than three-to-one.

NAVIGATION, AIR:rD-GROUND AND AIR:rD­AIR COMBAT MODES, The F-5 HUDWAC modes are selected automati­cally, based on the arm­ing switch pOSition. They include Navigation (with a landing sub-mode), Con­tinuously Computed Impact Point (CClP)

and Continuously Com­puted Release Point (CCRP), for air-to-

ground weapon delivery. Air-to-air modes include Air-to-Air Missile, Lead Computing Optical Sight (LCOS) and Dogfight, a combination of the Missile and Gun modes.

Addit ionally: an "Elec­tronic Bullet" mode allows realistic, effective air-combat training .

A COST-EFFECTIVE SYSTEM DESIGNED FOR RELIABILITY, SUPPORTABILITY, AND GROWTH. The F-5 HUDWAC utilizes technol­ogy and hardware derived from GEC Avionics' combat tested, and highly successful. major produc­tion Head Up Display programs. Incorporation of these tactically proven electronic components achieves both an improved MTBF and lower overall costs, since the majority of the system's elements are already in production.

F-S ElF HUDWAC TODAY

Engineered for f uture growth, the Electronics Unit is designed to interface w ith exist­ing and future sensors and w ith weapons systems (such as the APG-69 radar or the AI M-9P-4 missile) which might also be added as part of an aircraft mod­ification program. The unit is reprogrammable, easily accom­modating new weapon con­figurations.

Because the HUDWAC increases weapons delivery accu­racy, the system also results in lower training costs, as fewer

sorties are needed to maintain pilot proficiency.

GEC AVIONICS, A WORLD LEADER IN HUDWAC TECHNOLOGY, With more than 20 years of Head Up Display experience, GEC Avi­onics is a world leader in HUD technology. Over 6,000 systems have been produced and deployed in more than 25 different types of combat aircraft around the world, including the F-16, A-4, A-7, A-1O, the Mirage, the Buc­caneer and others.
