A cockpit system is on every aircraft, without a cockpit a pilot would not have a spot to sit to fly the plane. Or you can look at it from a different perspective and say that a cockpit is anywhere on an aircraft that is engineered for a pilot to control flying the plane. Traditionally the cockpit is found in the front of the aircraft, which is also known to instructors and pilots as the flight deck area, controlled from a pilot on the ground and in the air. The essential controls in the cockpit or flight deck are; MCP, PFD, ND, EICAS, FMS / CDU and also the back up instruments.
In order from the list above first is the MCP, which is short for Mode Control Panel, can be used to control Heading, Speed, Altitude, Vertical Speed, Vertical Navigation, and Lateral Navigation of the aircraft. This can also be used to give the pilot a little rest once he or she reaches their desired altitude by engaging the autopilot, or to make changes that are set after his or her rest by disengaging the autopilot.
Next is the PFD, which is short for Primary Flight Display and in most cases will include a digitized view of the altitude indicator, air speed and altitude indicators also the vertical speed indicator. The Primary Flight Display can also be used as a tool for military which the engaged and armed auto-flight system modes will be present along with some type of indicator values for altitude, speed, vertical speed and heading.
Also as listed is the ND, short for Navigation Display known to be adjacent to the Primary Flight Display. This shows the route map and information, current wind speed and wind direction just like your typical GPS but trust me this way way more high-tech. as it should be meet the complicated needs of the pilot.
Now the FMS, which is short for Flight Management System is used for the pilot to check the Flight Plan, Speed Control, Navigation Control, plus much more that can be found in the FAA handbooks that is provided on our website for FREE.
Last but not least considering it is probably the most important cockpit instrument giving an emergency situations since and since they are the most horrific situations especially since you are on the instruments so much, where as for example a car, the RPM and MPH are not really needed to drive, even though they do help to indicate when you are a few MPH over the speed limit to not get a ticket, they are not needed as mandatory as an aircraft instrument panel controls are because if a control goes out the pilot is pretty much screwed, especially if it is a pilot who is not advanced, very scary.
Well engineers have thought this through and have figured out that without a back-up instrument panel the pilot has a greater chance at crashing than not measuring the important factors that are needed to land the aircraft even if the pilot is getting assistance via the CV radio , which is really scary.
