what are important factors concerning duality
No/minimise excessive concentration or fatigue
controlled equally safely by the seating positions of both pilots
each pilot has a sufficiently clear view + minimum change in view (head movement)
other seats must be installed so make tasks effectively and without negative influence
what are important regularization besides duality
avoid misunderstandings, while allow mutual control of both pilots
priority: frequently observed information is displayed in the center
redundancy: more important information are displayed multipolar times
instrument arrangement EASA CS-25
Overhead panel, how are the buttons&switches organized
More often used buttons in a general flight are in the front, less often are far back.
For example lights ins the front
turbines kill switch far in the back
far back are fused
Historical development of the cockpit
the growing number of instruments and their information still needed to be presented in a manageable way
instrument diversity has given way to a few highly integrated cockpit displays (The right information at the right time) -> Development of so-called information hierarchies
complex systems required new forms of presentation over conventional clock instruments: Graphics and colour play a decisive role -> the equipment industry (Honeywell, Aerospatiale, Sextant, Diehl) are entering fierce competition
manufacturers e.g. Boeing and Airbus compete in display and operating concept

What is EIS
EIS (Electronic Instrument System with 6-8 CRT consisting of
ECAM (Electronic Centralized Aircraft Monitoring) and
EFIS (Electronic Flight Instrument System) and
important instruments as a mechanical back-up
What is ECAM
Electronic centralised aircraft monitoAn electronic centralised aircraft monitoring (ECAM) is a system that monitors aircraft functions and relays them to the pilots. It also produces messages detailing failures and in certain cases, lists procedures to undertake to correct the problem.r
What is EFIS
An electronic flight instrument system (EFIS) is a flight deck instrument display system that displays flight data electronically rather than electromechanically.
primary flight display (PFD),
multi-function display (MFD),
engine indicating and crew alerting system (EICAS)
. Early EFIS models used cathode ray tube (CRT) displays, but liquid crystal displays (LCD) are now more common. The complex electromechanical attitude director indicator (ADI) and horizontal situation indicator (HSI) were the first candidates for replacement by EFIS. Now, however, few flight deck instruments cannot be replaced by an electronic display.
