The HESA Kowsar ( Persian : کوثر , also spelt Kosar ) is an Iranian fighter jet based on the American Northrop F-5 . The aircraft is equipped with new fourth generation avionics in combination with an advanced fire control system .
46-516: Western analysts have described the plane to be inefficient as a weapon, but having potential for training a new generation of Iranian fighter pilots. According to the Iranian state-media, this fighter jet has "advanced avionics" and multipurpose radar, and it was "100-percent indigenously made". It also uses digital data networks, a glass cockpit , heads-up display (HUD), ballistic computers and smart mobile mapping systems. On November 3, 2018, there
92-459: A Liquid-crystal display or CRT display device . Representations of older six pack or "steam gauge" instruments are combined on one compact display, simplifying pilot workflow and streamlining cockpit layouts. Most airliners built since the 1980s—as well as many business jets and an increasing number of newer general aviation aircraft—have glass cockpits equipped with primary flight and multi-function displays (MFDs). Cirrus Aircraft
138-437: A flight management system , do-not-exceed speeds for the current configuration, stall speeds, selected altitudes and airspeeds for the autopilot, and so on. The vertical speed indicator , usually next to the altitude indicator, indicates to the pilot how fast the aircraft is ascending or descending, or the rate at which the altitude changes. This is usually represented with numbers in "thousands of feet per minute." For example,
184-399: A trackball , thumb pad or joystick as a pilot-input device in a computer-style environment. Many of the modifications offered by the aircraft manufacturers improve situational awareness and customize the human-machine interface to increase safety. Modern glass cockpits might include synthetic vision systems (SVS) or enhanced flight vision systems (EFVS). Synthetic vision systems display
230-432: A PFD includes at a minimum, an airspeed indicator, turn coordinator, attitude indicator, heading indicator, altimeter, and vertical speed indicator [14 CFR Part 61.129(j)(1)]. The details of the display layout on a primary flight display can vary enormously, depending on the aircraft, the aircraft's manufacturer, the specific model of PFD, certain settings chosen by the pilot, and various internal options that are selected by
276-538: A backup battery. In 2010, the NTSB published a study done on 8,000 general aviation light aircraft. The study found that, although aircraft equipped with glass cockpits had a lower overall accident rate, they also had a larger chance of being involved in a fatal accident. The NTSB Chairman said in response to the study: Training is clearly one of the key components to reducing the accident rate of light planes equipped with glass cockpits, and this study clearly demonstrates
322-512: A measurement of "+2" indicates an ascent of 2000 feet per minute, while a measurement of "-1.5" indicates a descent of 1500 feet per minute. There may also be a simulated needle showing the general direction and magnitude of vertical movement. At the bottom of the PFD is the heading display, which shows the pilot the magnetic heading of the aircraft. This functions much like a standard magnetic heading indicator , turning as required. Often this part of
368-650: A realistic 3D depiction of the outside world (similar to a flight simulator ), based on a database of terrain and geophysical features in conjunction with the attitude and position information gathered from the aircraft navigational systems. Enhanced flight vision systems add real-time information from external sensors, such as an infrared camera. All new airliners such as the Airbus A380 , Boeing 787 and private jets such as Bombardier Global Express and Learjet use glass cockpits. Many modern general aviation aircraft are available with glass cockpits. Systems such as
414-462: A reverse engineering of Sidewinder missiles, or twelve 250 kg (550 lbs) bombs or five 450 kg (1000 lbs) bombs or two 900 kg (2000 lbs) bombs. Kowsar has an Italian Grifo radar (a Chinese model or its domestic production has been used) with a range of 93 km (57 miles) that can engage two targets simultaneously. There were reports of a crash by an Iranian-operated F-5 days after the Kowsar's existence
460-636: A serious glass-cockpit blackout, losing half of the Electronic Centralised Aircraft Monitor ( ECAM ) displays as well as all radios, transponders, Traffic Collision Avoidance System ( TCAS ), and attitude indicators. The pilots were able to land at Newark Airport without radio contact in good weather and daylight conditions. Airbus has offered an optional fix, which the US National Transportation Safety Board (NTSB) has suggested to
506-483: A traditional cockpit relies on numerous mechanical gauges (nicknamed "steam gauges") to display information, a glass cockpit uses several multi-function displays and a primary flight display driven by flight management systems , that can be adjusted to show flight information as needed. This simplifies aircraft operation and navigation and allows pilots to focus only on the most pertinent information. They are also popular with airline companies as they usually eliminate

#1732793556037552-440: A true departure. They look and behave very similarly to other computers, with windows and data that can be manipulated with point-and-click devices. They also add terrain, approach charts, weather, vertical displays, and 3D navigation images. The improved concepts enable aircraft makers to customize cockpits to a greater degree than previously. All of the manufacturers involved have chosen to do so in one way or another—such as using
598-581: Is reflected in the total acceptance of electronic flight displays. The safety and efficiency of flights have been increased with improved pilot understanding of the aircraft's situation relative to its environment (or " situational awareness "). By the end of the 1990s, liquid-crystal display (LCD) panels were increasingly favored among aircraft manufacturers because of their efficiency, reliability and legibility. Earlier LCD panels suffered from poor legibility at some viewing angles and poor response times, making them unsuitable for aviation. Modern aircraft such as
644-488: Is shown in different formats on different PFDs. For example, one PFD may show the current angle of attack as a tiny dial near the attitude indicator, while another may actually superimpose this information on the attitude indicator itself. Since the various graphic features of the PFD are not labeled, the pilot must learn what they all mean in advance. A failure of a PFD deprives the pilot of an extremely important source of information. While backup instruments will still provide
690-563: The Boeing 737 Next Generation , 777 , 717 , 747-400ER , 747-8F 767-400ER , 747-8 , and 787 , Airbus A320 family (later versions), A330 (later versions), A340-500/600 , A340-300 (later versions), A380 and A350 are fitted with glass cockpits consisting of LCD units. The glass cockpit has become standard equipment in airliners , business jets , and military aircraft . It was fitted into NASA's Space Shuttle orbiters Atlantis , Columbia , Discovery , and Endeavour , and
736-604: The Diamond DA42 . The Lockheed Martin F-35 Lightning II features a "panoramic cockpit display" touchscreen that replaces most of the switches and toggles found in an aircraft cockpit. The civilian Cirrus Vision SF50 has the same, which they call a "Perspective Touch" glass cockpit. Unlike the previous era of glass cockpits—where designers merely copied the look and feel of conventional electromechanical instruments onto cathode-ray tubes—the new displays represent
782-576: The Garmin G1000 are now available on many new GA aircraft, including the classic Cessna 172 . Many small aircraft can also be modified post-production to replace analogue instruments. Glass cockpits are also popular as a retrofit for older private jets and turboprops such as Dassault Falcons , Raytheon Hawkers , Bombardier Challengers , Cessna Citations , Gulfstreams , King Airs , Learjets , Astras , and many others. Aviation service companies work closely with equipment manufacturers to address
828-724: The McDonnell Douglas MD-80 , Boeing 737 Classic , ATR 42 , ATR 72 and in the Airbus A300-600 and A310 , used electronic flight instrument systems (EFIS) to display attitude and navigational information only, with traditional mechanical gauges retained for airspeed, altitude, vertical speed, and engine performance. The Boeing 757 and 767-200/-300 introduced an electronic engine-indicating and crew-alerting system (EICAS) for monitoring engine performance while retaining mechanical gauges for airspeed, altitude and vertical speed. Later glass cockpits, found in
874-475: The attitude indicator and horizontal situation indicator (HSI). However, the 2707 was cancelled in 1971 after insurmountable technical difficulties and ultimately the end of project funding by the US government. The average transport aircraft in the mid-1970s had more than one hundred cockpit instruments and controls, and the primary flight instruments were already crowded with indicators, crossbars, and symbols, and
920-566: The integrated standby instrument system . Glass cockpits originated in military aircraft in the late 1960s and early 1970s; an early example is the Mark II avionics of the F-111D (first ordered in 1967, delivered from 1970 to 1973), which featured a multi-function display . Prior to the 1970s, air transport operations were not considered sufficiently demanding to require advanced equipment like electronic flight displays. Also, computer technology
966-673: The Boeing 737NG , 747-400 , 767-400 , 777 , Airbus A320 , later Airbuses, Ilyushin Il-96 and Tupolev Tu-204 have completely replaced the mechanical gauges and warning lights in previous generations of aircraft. While glass cockpit-equipped aircraft throughout the late 20th century still retained analog altimeters , attitude , and airspeed indicators as standby instruments in case the EFIS displays failed, more modern aircraft have increasingly been using digital standby instruments as well, such as

While
1104-406: The PFD. The great variability in the precise details of PFD layout makes it necessary for pilots to study the specific PFD of the specific aircraft they will be flying in advance, so that they know exactly how certain data is presented. While the basics of flight parameters tend to be much the same in all PFDs (speed, attitude, altitude), much of the other useful information presented on the display
1150-676: The Russian Soyuz TMA model spacecraft that were launched for the first time in 2002. By the end of the century glass cockpits began appearing in general aviation aircraft as well. In 2003, Cirrus Design 's SR20 and SR22 became the first light aircraft equipped with glass cockpits, which they made standard on all Cirrus aircraft. By 2005 , even basic trainers like the Piper Cherokee and Cessna 172 were shipping with glass cockpits as options (which nearly all customers chose), as well as many modern utility aircraft such as
1196-588: The US Federal Aviation Administration (FAA) as mandatory, but the FAA has yet to make it a requirement. A preliminary NTSB factsheet is available. Due to the possibility of a blackout, glass cockpit aircraft also have an integrated standby instrument system that includes (at a minimum) an artificial horizon , altimeter and airspeed indicator . It is electronically separate from the main instruments and can run for several hours on
1242-424: The aircraft's owner (i.e., an airline, in the case of a large airliner). However, the great majority of PFDs follow a similar layout convention. The center of the PFD usually contains an attitude indicator (AI), which gives the pilot information about the aircraft's pitch and roll characteristics, and the orientation of the aircraft with respect to the horizon . Unlike a traditional attitude indicator, however,
1288-446: The attitude indicator are usually the airspeed and altitude indicators, respectively. The airspeed indicator displays the speed of the aircraft in knots , while the altitude indicator displays the aircraft's altitude above mean sea level ( AMSL ). These measurements are conducted through the aircraft's pitot system, which tracks air pressure measurements. As in the PFD's attitude indicator, these systems are merely displayed data from

Ofir Gendelman , spokesperson of the prime minister's office tweeted "The Iranian regime unveils the Kowsar plane and claims that it is ‘the first 100% locally-manufactured Iranian fighter jet'. It boasts about its offensive capabilities. But I immediately noticed that this is a very old American war plane (it
1380-427: The display shows not only the current heading, but also the current track (actual path over the ground), rate of turn , current heading setting on the autopilot, and other indicators. Other information displayed on the PFD includes navigational marker information, bugs (to control the autopilot ), ILS glideslope indicators, course deviation indicators , altitude indicator QFE settings, and much more.

1472-457: The growing number of cockpit elements were competing for cockpit space and pilot attention. As a result, NASA conducted research on displays that could process the raw aircraft system and flight data into an integrated, easily understood picture of the flight situation, culminating in a series of flights demonstrating a full glass cockpit system. The success of the NASA-led glass cockpit work
1518-551: The launch of STS-101 . Columbia was the second orbiter with a glass cockpit on STS-109 in 2002, followed by Discovery in 2005 with STS-114 , and Endeavour in 2007 with STS-118 . NASA's Orion spacecraft will use glass cockpits derived from Boeing 787 Dreamliner . As aircraft operation depends on glass cockpit systems, flight crews must be trained to deal with failures. The Airbus A320 family has seen fifty incidents where several flight displays were lost. On 25 January 2008, United Airlines Flight 731 experienced
1564-528: The layout of a PFD can be very complex, once a pilot is accustomed to it the PFD can provide an enormous amount of information with a single glance. Starting with the A350-1000 , Airbus proposes a common symbology on the PFD and HUD centered on a flightpath vector and an energy cue instead of a flight director , supplementing the usual pitch and heading indications to improve situational awareness , and helping incorporating synthetic vision into
1610-526: The life and death importance of appropriate training on these complex systems... While the technological innovations and flight management tools that glass cockpit-equipped airplanes bring to the general aviation community should reduce the number of fatal accidents, we have not—unfortunately—seen that happen. Primary flight display A primary flight display or PFD is a modern aircraft instrument dedicated to flight information. Much like multi-function displays , primary flight displays are built around
1656-506: The mechanical gyroscope is not contained within the panel itself, but is rather a separate device whose information is simply displayed on the PFD. The attitude indicator is designed to look very much like traditional mechanical AIs. Other information that may or may not appear on or about the attitude indicator can include the stall angle, a runway diagram, ILS localizer and glide-path “needles”, and so on. Unlike mechanical instruments, this information can be dynamically updated as required;
1702-533: The need for a flight engineer , saving costs. In recent years the technology has also become widely available in small aircraft. As aircraft displays have modernized, the sensors that feed them have modernized as well. Traditional gyroscopic flight instruments have been replaced by electronic attitude and heading reference systems (AHRS) and air data computers (ADCs), improving reliability and reducing cost and maintenance. GPS receivers are usually integrated into glass cockpits. Early glass cockpits, found in
1748-631: The needs of the owners of these aircraft. Today, smartphones and tablets use mini-applications, or "apps", to remotely control complex devices, by WiFi radio interface. They demonstrate how the "glass cockpit" idea is being applied to consumer devices. Applications include toy-grade UAVs which use the display and touch screen of a tablet or smartphone to employ every aspect of the "glass cockpit" for instrument display, and fly-by-wire for aircraft control. The glass cockpit idea made news in 1980s trade magazines, like Aviation Week & Space Technology , when NASA announced that it would be replacing most of
1794-407: The stall angle, for example, can be adjusted in real time to reflect the calculated critical angle of attack of the aircraft in its current configuration (airspeed, etc.). The PFD may also show an indicator of the aircraft's future path (over the next few seconds), as calculated by onboard computers, making it easier for pilots to anticipate aircraft movements and reactions. To the left and right of
