What is a flight control computer?
The flight control computer is at the core of any modern aircraft, both manned and unmanned. In both cases, the flight control computer actuates the primary flight control surfaces to drive the flight path of the aircraft, while also providing finer control for stability.
What computer or device flies a plane?
A flight computer is a form of circular slide rule used in aviation and one of a very few analog computers in widespread use in the 21st century. Sometimes it is called by the make or model name like E6B, CR, CRP-5 or in German, as the Dreieckrechner.
What is electromagnetic interference in aviation?
Electromagnetic interference (EMI) from passenger-carried portable electronic devices (PED) on commercial airplanes has been reported as being responsible for anomalous events during flight. The operation of PEDs produces uncontrolled electromagnetic emissions that could interfere with airplane systems.
How do stability augmentation system work?
A stability augmentation system (SAS) is another type of automatic flight control system; however, instead of maintaining the aircraft required altitude or flight path, the SAS will move the aircraft control surfaces to damp unacceptable motions. SAS automatically stabilizes the aircraft in one or more axes.
Which computer is used in aircraft control system?
Thales Fly-by-wire Flight Control Computer (FCC) for aircraft. The Flight Control Computer (FCC) is a high integrity, low SWaP (Size, Weight and Power) airborne computer that comprises two channels operating in an active/standby configuration.
How does a flight control system work?
Traditional mechanical and hydro-mechanical flight control systems use a series of levers, rods, cables, pulleys, and more which pilots move to adjust control surfaces to aerodynamic conditions. Their “hands on” design gives pilots a direct, tactile feel for how the aircraft is handling aerodynamic forces as they fly.
How do computer based technologies assist in aircraft design manufacturing and operations?
Computer-aided design and computer-aided manufacture (CAD/CAM) have greatly reduced the cost of producing aircraft. Computers produce accurate drawings and can alert designers to possible conflicts before a design is produced. They can also manufacture parts more precisely and faster than humans.
What are the five information that flight management computer displays?
Navigation database
- Waypoints/Intersection.
- Airways.
- Radio navigation aids including distance measuring equipment (DME), VHF omnidirectional range (VOR), non-directional beacons (NDBs) and instrument landing systems (ILSs).
- Airports.
- Runways.
- Standard instrument departure (SID)
- Standard terminal arrival (STAR)
How the electromagnetic environment affects aircraft?
Lightning and high-intensity radiated fields (HIRF) can degrade aircraft safe operation and even cause catastrophic effects without sufficient protection against electromagnetic environmental effects (E3). RF transmitters and lightning may also cause EMI issues for spacecraft and launch pads.
How can aircraft reduce electromagnetic interference?
One major way to combat EMI is to provide shielding of various line replaceable units (LRUs) and harnesses. Shielding a device or system not only reduces EMI emissions, it improves susceptibility performance.
What is flight control augmentation?
Control augmentation system is a common part of modern airplane control and is best characterized as a form of tracking control. In this paper, a flight control system is to be designed that augments both stability and control for an unmanned aerial vehicle called Aerosonde.
What frequencies are available to aircraft manufacturers when conducting test flights?
These frequencies are available to aircraft manufacturers as they conduct test flights. Test flight frequencies are sprinkled throughout the VHF aviation band between 123.125 MHz and 123.575 MHz. Within this range are 123.4 MHz and 123.45 MHz, colloquially referred to as “Finger” and “Fingers” respectively.
What is the best VHF frequency range for aviation radio systems?
To support full VHF communications, the FAA recommends that all aircraft with older 360-channel systems should be retrofitted with a 760-channel piece of equipment with 25 kHz channel spacing which is capable of operating in the 118.000 to 136.975 MHz band. Signals that are transmitted and received via aviation radio can be of more than one type.
What is the frequency of an IFF transponder?
An IFF transponder receives interrogation pulses at one frequency (1030 MHz), and sends the reply pulses at a different frequency (1090 MHz) Proper use of IFF facilitates rapid engagement of enemy aircraft, conserves air defense assets, and reduces risk to friendly aircraft
What do the control instruments display on an airplane?
The control instruments display immediate attitude and power changes and are calibrated to permit adjustments in precise increments. The instrument for attitude display is the attitude indicator. The control instruments do not indicate aircraft speed or altitude.
