Aircraft Flight Deck (Cockpit) Layout
The aircraft flight deck is a better term than the older usage of the word cockpit, which originated in ship design in the sixteenth century; it was similar to men working in a confined area under stress, like cocks that were forced to fight in a pit for sport. Crew station is another term meaning the same as a workplace for operators of any type of vehicle. To standardize terminology, this book uses flight deck, intended specifically for aircraft. The flight deck serves as a human-machine interface by providing (1) an outside reference of topography through the cabin windows, (2) onboard instruments to measure flight parameters, (3) control facilities to operate an aircraft safely for the mission role, and (4) management of aircraft systems (e. g., the internal environment). Future designs with advanced displays could result in a visually closed flight deck (i. e., a TV replacing the windows). The front – fuselage shape can be influenced by the flight-deck design. Transport aircraft have two pilots sitting next to one another at a pitch of about 1.2 meters in smaller aircraft to 1.4 meters in larger aircraft. Understanding the flight-deck arrangements also provides a sense of the equipment requirements that result in a measure of the associated weights involved. The space and adequacy of vision polar, which establishes the window-size requirements, also can be better understood.
Both civil and military aircraft pilots have the following common functions:
• mission management (planning, checks, takeoff, climb cruise, descent, and landing)
• flight-path control
• systems management
• communication*
• navigation*
• routine postflight debriefing
• emergency action when required (drills differ between civil and military aircraft)*
*Civil aircraft pilots are assisted by ground control (i. e., communication and navigation), whereas in a critical situation, combat pilots must manage the aircraft themselves – which is a significant difference. Both situations may require taking emergency actions, but for a combat pilot, this could be drastic in nature (i. e., ejection; see Section 15.10). In addition, military aircraft pilots have an intense workload, as follows:
• mission planning (e. g., Lo/High combination; see Chapter 13); this is required for mission management (preflight briefing may change if the situation demands)
• target acquisition
• weapons management and delivery
• defensive measures and maneuvers
• counterthreats; use of tactics
• management of situation when hit
• in-flight refueling, where applicable
• detailed postflight briefing in special situations
The military aircraft flight deck is under more stringent design requirements. The civil aircraft flight-deck design is in the wake of military standards and the provision of space is less constrained. This is why the military aircraft flight deck is discussed first (see Figure 15.16). An aircraft flight-deck design has changed dramatically since the early analog-dial displays (i. e., four-engine aircraft gauges now fill the front panel; see Figure 15.17) to modern microprocessor-based data management in an integrated, all-glass, multifunctional display (MFD), which is also known as an electronic flight information system (EFIS).
