Commercial Aircraft Cockpit

The current style of human life has created substantial need for faster services and less wait time as well as access the remote regions as soon as possible, which was led to the invention of the airplane in different types such as passenger and cargo aircrafts and etc.

Aircraft cockpit plays the pivotal role in navigation of an airplane. Consequently, even minor technical defects in the aircraft systems can have irreparable and fatal consequences. Therefore, numerous research on the design, modeling and optimization of the aircrafts, has taken place especially within the cockpit, by well-known corporations such as Boeing and Airbus. Although a large number of research projects have been devoted to this field, there is still a lot to do.

In general the cockpits can be categorized as follow:

1. Analog Cockpit:

The first type of cockpit which have used in airplanes were Electromechanical Cockpit, with analog displays and dials.

2. Analog and Glass cockpit:

With the advent of digital indicators, many advances have been occurred in the aircrafts cabin design and controlling systems.

3. Glass Cockpit:

A glass cockpit is an airplane that features electronic or digital displays on LCD screens as opposed to using traditional analog dials or gauges that were commonly found in an airplane cockpit. Because the newer systems are more automated, they are more accurate and the integration of controls better than in traditional analog systems.

In a glass cockpit, pilots still use the traditional T-formation scan to crosscheck, but the digital displays make the process faster and more efficient. Data is displayed more clearly, reducing pilot workload and fatigue, and it is less likely that a critical gauge will be missed during the scan. The controls in a glass cockpit have fewer mechanical components to break down or return false readings.

Technical Field:

From the technical point of view, the design of aircraft cockpits involves ergonomics, layout, psychological issues as well as the fomentation of the cabin.

Ergonomics:

The ergonomics design of the airplane cockpit is of great importance to the efficiency of flight crew operation and has a major impact on the flight safety. Ergonomics (or human factors) is the scientific discipline concerned with the understanding of interactions among humans and other elements of a system, and the profession that applies theory, principles, data and methods to design in order to optimize human well-being and overall system performance.

Layout:

The layout of the cockpit, especially in the military fast jets, has undergone standardization, both within and between aircraft different manufacturers and even different nations. The layout and function of cockpit displays controls are designed to increase pilot situation awareness without causing information overload. In the past, many cockpits, especially in fighter aircrafts, limited the size of the pilots that could fit into them. Now, cockpits are being designed to accommodate from the 1st percentile female physical size and to the 99th percentile male size.

Psychological issues:

From psychological issues perspective, the design and layout of cockpit displays and the size of the cabin as well as the color of cabin displays must be such that during the flight pilots can be more relaxed.

Cabin dimensions:

Cockpit dimensions strongly depends on the model of aircraft.

Background Art: Ergonomics:

It seems like ergonomy in the cockpit of Boeing is not a priority in some. Some ergonomic changes have taken place in some models due to the size of aircraft such as in the cases of 737(800, 900, MAX) and 747(400 and 8i) airplane.

Airbus has made some substantial changes to the cockpit. The various small size digital monitors have in the cabin of the aircraft A340, A330 and A320.

Bombardier and Embraer, as well as companies in Ergonomics changes have been inactive.

Layout:

Equipment layout is related to ergonomics it seems that companies are named, so many changes have imposed their originality and style. However, the cabin can be provided with better alignment.

Psychological issues:

Companies named in this context have carried out a lot of efforts and by seeing the cabins we find that this issue is applied. But on the basis of originality and design style and that companies have carried out in the past years, but have been inactive in the improvement of these issues.

Cabin dimensions:

In the design of each piece, part, is proportional to the size of the aircraft.

The Company had considered these issues, but these variations were proportional to the size of aircraft.

Summary of Invention:

Based on mentioned points, all efforts have been done about simplification, ergonomics, equipment layout, psychological and economic of the cabin. In the field of ergonomics by reducing the height of the main panel, has been provided more leg space for pilots. in the field of Sort components, to have easy access in a short time, due to a reduction in the number of panels, each have been installed in the a suitable place. In the field of psychology, because reducing the large volume of buttons and panels, is provided spiritual and mental tranquility pilots during the flight. By reducing equipment and simplification of the cabin, making it with low cost is possible.

Technical Problem:

In the past, the cabin would been just analog that had less accuracy.

With the passage of time, digital systems have been replaced analog systems, but this was not completely replacement. Large companies, according to the style and originality in design and ergonomics of the cabin in order to simplify and other points mentioned, considerable efforts have not applied. That this has caused to pilots on long flights were experiencing very tired.

Solution to Problem:

In this plan the volume of keys and equipment according to safety is low and ergonomics when using components experiencing been reviewed and improved. In the field of Components layout, according to the terms of their low volume of supplies is easy and due to the working conditions and the number of times used, have been installed in the right places. In the field of psychology, because of the simplicity of cabin, the pilots will not be confused in an emergency and are relaxed during the flight and control and guidance of aircraft more safely done. Due to the mentioned issues, the construction cost of the plan is affordable and inexpensive.

Advantageous Effects of Invention:

- Production with low cost in the long term

- Intellectual comfort and reducing fatigue pilots, in the flight of long-term

- Reducing the volume of key and improvement of panel

- Easy access to equipment in emergency situations

- Conversion of some buttons to touch screens

- Suitable ergonomics Equipment

- It can be installed in all aircrafts such as medium types

- Not using the analog systems

- Effective use of all the cabin’s space

- simplify and reduce the performance of cabin’s equipment

- Lower consumption of raw materials

- The number of mold less to build

- Pedestal is to measure the length and width of 794.82*520 mm and monitor dimension is 330*184.13 in 45 degrees that represents this panel is short and compact. (Fig1)

- Instead of an analog system and buttons, touch screens with dimensions of 174 * 127 mm is used. (Fig1)

- Dimensions of Overhead Panel is 716*667 mm. Because of the low volume used in all cabins. (Fig3)

- “Engine start Mode” on the left and in the middle of the panel, there is a three-state volume (Norm, Crank, IGN/START) that Due to avoid confusion and facilitate the start-engine aircraft, has been moved from Pedestal to Overhead Panel As well as other sectors have also changed for convenience. (Fig4)

- Main Panel dimensions is standard And its height to provide a greater foothold, reduced to 310 mm And by simplifying the cabin, the upper part has been reduced to 86 mm. (Fig5)

- In the upper part of the main panel, in the “IAS / Mach” and “FMC / SPD”, instead of “Flight change key” and other keys, is used by one key and multistate volume and have been removed the buttons of “ILS” and “A/T” and “COM (1, 2, 3, 4)”. (Fig6)
