Comparisons of the changes from F-5E/F Tiger II

Before the upgrade After the upgrade

Flight performance data

Read through the numerous dials and switches from the control panel. Read through the Heads Up Display (HUD), allowing pilot to keep his focus to the front.

Position determination

Use of printed maps, compass and ground control information. Inertial Navigation System automatically computes the position with error margin of 0.8 nautical miles per hour.

Weapons selection

Involves taking hands off the controls and flipping the switches. Selection through buttons located on control and throttle sticks. Buttons also used for selection of screen displays.

Weapons accuracy

Dependant on pilot's judgement and experience. Computer calculations ensure greater accuracy.

Mission plans

Scribbled on note pads and changes had to be done manually by pilots in mid-air. Done on computer and fed into the aircraft's computer through a cartridge.
Digitised maps can be downloaded and displayed on the screens making mid-flight changes easier.

Back-up instruments

No back-ups. Two computers and one serving as back-up due to larger space for back-up instruments and fuel level gauges. Ensure fail-safe reliability and higher mission success rate.
