Ergonomics
Chapter 1.3
The Seat Position
Optimal height of the seat, armrest, seatbelt adjustment and distance to the flight controls.
This allows you to reach the controls easily and have an optimal view.
With the known seat position and posture of the head all the reference points of the aeroplane can be defined.
Seat Adjustment
You should know your own personal and optimal sitting position in the airplane. Before every flight, you should be seated in this ideal position.
Adjustment of height, depth and inclination.
Armrests
If the airplane is equipped with ARMRESTS, you should use them.
When using control sticks, the elbow should rest on the thighs to improve stick control precision.
Seatbelts
The seatbelt must be tightened.
The shoulder harness may be looser, but it should not impede access to the controls.
Reading the Instruments
From your position, you should be able to recognize the position of switches and levers, and be able to read the instruments.
The important instruments are displayed in such a way that a pilot sitting on the left does not need to move the body in order to read them, and the parallax is compensated.
Heating, Ventilation and Air Conditioning
Adequate information on the equipment of the aircraft are described in the airplane's AFM:
- Heating
- Ventilation
- Air conditioning
- Sun Screens
Internal Lights
Light sources for iluminating the instuments, flight controls, levers and switches, and for chart reading are installed in adequate places.
The following different lights are found:
- Cabin Light
- Map/Chart Light
- Grimes Lights
- Instrument Lights
Questions
Why is it important for the seating position to be optimal and always the same?
References for maintating flight attitude Optimal view of the outside for airspace observation Best reachability of Flight Controls, Switches & Levers Optimal view of all instruments
Where would you find the necesary information for the proper use of ventilation systems?
