In modern-day military aviation, displays are the most
a reliable method of presenting information to the pilots,
with the increment of more sophisticated controls
given to the pilots.
2. Evolution of
Displays
• A piece of string was used by Wright brothers as a slip
indicator
• CRT displays were first introduced to the aviation
industry through military aircrafts in 1940
• In modern day military aviation, displays are the most
reliable method of presenting information to the pilots,
with the increment of more sophisticated controls
given to the pilots
3. Visual Display
Design
• Displays must present information in a way that
help the brain of the pilot in its processing tasks
even when pilots performance is affected by
fatigue or stress.
• General characteristics of visual display design
• Light and visibility
• Method of presenting
• Standards of presenting
• Distinguish the most important information
• Angle of the visual display to be viewed
• Viewing distance
• Mode of the display
• Dials marks and shapes
4. Glass Cockpit
• More effective utilization of high priority panel
space
• Greater flexibility
5. Control
Designing
• Sight and reach
• Direction of movement of the control
• Warrick’s principle
• Control resistance
• Control coding
6. Control
Designing
• Sight and reach
• Direction of movement of the control
• Warrick’s principle
• Control resistance
• Control coding
7. Control
Designing
• Sight and reach
• Direction of movement of the control
• Warrick’s principle
• Control resistance
• Control coding
8. Control
Designing
• Sight and reach
• Direction of movement of the control
• Warrick’s principle
• Control resistance
• Control coding
9. Keyboard
Configurations
• Keyboards play a prominent role in modern
military flight decks to input data into the system
by the pilot. Keys and rows of keys used in
military aviation spaced by around 2 cm.
• QWETY keyboard layout
• Not efficient
• Individual finger loading (1% - 22%)
• Left hand work (60%)
• DSK keyboard layout
• More efficient
• Individual finger loading (1% - 8%)
• Left hand work (50%)
12. Space and
Layout
Design
• For optimized performance comfort and safety
human factors must be considered in terms of
following aspects.
• Flight deck basic geometry
• Seat design
• Arrangement of flight instruments
13. Anthropometry
and
Biomechanics
• Human dimensions and forces are pertinent
to the design of aircraft equipment to ensure
optimum effectiveness.
Anthropometry Data Design Information
• Size of limbs
• Weight
• Stature (height)
• Seated eye height
• Seated reachability with
restraining shoulder harness
• Seated reachability without
restraining shoulder harness
etc.
• Body forces (grip strength
etc.)
• Etc.
• optimum height of a work
surface
• minimum knee room
between seat rows
• location of controls, width
of a seat
• length of an arm rest
• height of a headrest
• seat cushion design
• Etc.
16. Windshield
Design
Factors to be considered in the design
of windshield
• Forward visibility
• Downward visibility
• Location of design eye position
