The Embraer EMB-145 family consists of a number of aircraft types produced by the Brazilian aircraft manufacturer Embraer . Its members include the regional aircraft ERJ 135 (type EMB-135 ), ERJ 140 (type EMB 135KL ) and ERJ 145 (type EMB-145), and ERJ for " E mbraer R egional J stands et". The aircraft family is one of the most widely produced regional aircraft in the world and is arguably the biggest competitor to the Bombardier Canadair Regional Jet . In addition, business jets ( Legacy 600 and Legacy 650) and various military variants are produced from the same type family .
history
When Canadair began planning its regional jet in 1989, Embraer also announced studies for an aircraft for around 50 passengers under the name EMB-145 “Amazon” - among other things because it became apparent that the development of the grafted aircraft Embraer / FMA was being developed CBA 123 Vector will have to discontinue. At that time, the engines were supposed to be mounted on the top of the wing, similar to the German jet VFW 614 , but this was quickly abandoned because of the poor performance values. For cost reasons, winglets were omitted and the fuselage cross-section of the Embraer EMB 120 or the Vector was retained and some of the new technologies developed in the latter aircraft were adopted; however, the fuselage cross-section is not insignificantly narrower than that of the Bombardier Canadair Regional Jet . After the planning was finished, construction began in 1993, so that the first flight took place on August 11, 1995. The first delivery to the airlines began in December 1996. The brand name "Embraer Regional Jet" was introduced in October 1997. At the same time, planning began for the closely related Embraer ERJ 140 and Embraer ERJ 135 models. In November 2007, Embraer announced that the 1000th aircraft from the ERJ series had been delivered to customers.
Commonality
Based on the basic model ERJ 145, the other models in this family are only derivatives, similar to the family concept at Airbus . The fuselage is largely the same as that of the significantly smaller Embraer EMB 120 turboprop aircraft . The ERJ 140 has a trunk equality of 95% to its two siblings.
Versions
ERJ 135
The history of the ERJ-135 began in 1989 when planning for the series began. However, construction of the ERJ 135 did not start until September 1997 and after the maiden flight on July 4, 1998, the first delivery took place in September 1999.
The fuselage is very similar to the Embraer EMB 120 and is 3.54 m shorter than the standard ERJ 145. There is space for 37 passengers in the cabin. The model is quite successful with 123 copies ordered so far (as of March 31, 2005) - not least because it is almost unrivaled in this segment after the bankruptcy of Dornier , which offered the 328JET as a competitor model .
ERJ 140
The program of the ERJ 140 began in September 1999 and the maiden flight of the ERJ 140 on 27 June 2000. The first delivery followed in late July 2001 to the American airline American Eagle Airlines , for which the aircraft was tailor-made.
The size of the ERJ-140 lies exactly between the two closely related series Embraer ERJ 135 and Embraer ERJ 145. The main difference to the ERJ 135 is the 2.2 m longer fuselage. By March 31, 2005, 94 firm orders had been placed for the ERJ 140. This type of aircraft was carried in-house under the name EMB 135KL and also registered with the American aviation authorities.
The ERJ 140 is in direct competition with the Bombardier CRJ440 .
ERJ 145
The project was first announced in 1989 under the name EMB-145 "Amazon". After planning, construction began in 1993, so that the maiden flight took place on August 11, 1995. Delivery to the airlines began in December 1996.
The passenger cabin has an interior width of only 2.10 m, so the rows of seats each have three seats, two on the right and one on the left of the aisle. The model is extremely successful with 682 firm orders (as of March 31, 2005) and is in direct competition with the Bombardier Canadair Regional Jet .
Legacy 600/650
The Embraer Legacy 600 is a business jet variant of the EMB-135.
Military variants
EMB 145 AEW & C
The EMB-145 AEW & C is a reconnaissance aircraft equipped with an AESA high-performance Erieye radar , similar to the AWACS , but much smaller and therefore cheaper to operate. It can be recognized by the radar antenna mounted lengthways on the fuselage. The addition AEW & C stands for Airborne Early Warning and Control . The military type designation is R99-A . The first flight took place on May 22, 1999.
Mexico (1 × EMB-145SA), the Greek (4 × EMB-145H) and the Brazilian air force (5 × EMB-145) are currently using this aircraft, the latter also for monitoring the Amazon region as part of the so-called SIVAM project. India has also signed a contract for three EMB-145SM aircraft, the first of which made its maiden flight on December 6, 2011.
EMB 145 RS / AGS

The EMB 145 RS / AGS is a reconnaissance aircraft equipped with numerous electronic and electro-optical surveillance systems . It can be recognized by a clear bulge under the hull. The addition RS / AGS stands for Remote Sensing / Air to Ground Surveillance (German: remote sensing / air-to-ground surveillance). The military type designation is R99-B .
The Brazilian Air Force is currently using this aircraft, among other things, to monitor the Amazon region as part of the so-called SIVAM project.
EMB 145 MP / ASW
The EMB 145 MP / ASW is an aircraft specially developed for reconnaissance at sea and combat operations against submarines. It can be recognized by a clear bulge under the fuselage, just like the sister model Embraer EMB 145 RS / AGS. The addition MP / ASW stands for Marine Patrol / Anti Submarine Warfare (German: Marine Monitoring / Anti-U-Bootkampf). The military type designation is P99 .
The Mexican Air Force currently uses this aircraft.
Incidents
- On 29 September 2006, one occurred collision an Embraer Legacy 600 with a Boeing 737-800 over the Brazilian Amazon region . The Embraer lost the winglet of the left wing and part of the left horizontal stabilizer, but was able to make an emergency landing on a military base. The Boeing crashed in the collision, killing all 154 passengers and crew.
- On July 18, 2005, the crew of an ERJ-145 was only just able to prevent the aircraft from leaving the runway due to aquaplaning at Nuremberg Airport . The machine turned around 180 ° during the braking maneuver, which caused slight damage to the structure. The reasons for this disruption were errors in the calculation of the approach speed (this was 20 kt, i.e. 37 km / h above the actual reference speed) and the condition of the runway, which was very wet due to a thunderstorm, which the crew was not aware of. In addition, the landing approach was too high due to the gust, which led to a late touchdown on the runway.
- On August 14, 2005, an ERJ-145 at Hanover Airport shot over the runway 27L as a result of aquaplaning and only came to a stop 161 meters after the end of the runway. One person was injured, the causes, according to the Federal Bureau of Aircraft Accident Investigation, were the fact that they landed on the much shorter runway 27L (this is 2340 meters long, the parallel runway 27R is 3800 meters), the late touchdown due to a tail wind, the lack of braking effect and the actuation of the emergency brake, which according to the investigators favored the aquaplaning.
