Boeing 737- 800ER ~ TDS

Boeing's Next Generation 737-800 and 737-900 are the largest members of the strong selling 737 family. Unlike the other Next Generation 737s, the -800 and -900 introduce new fuselage lengths, extending 737 single class seating range out to 189, compared with 100 in the original 737-100.

Like the -600 and -700, the -800 and -900 feature the Next Generation improvements including more efficient CFM56-7B turbofans, the new wing with greater chord, span and wing area, larger tail surfaces and the 777 style EFIS flightdeck with six flat panel LCDs which can present information as on the 777 or as on the 737-300/400/500 series, the latter allowing a common pilot type rating for the two 737 families. A HUD is optional. BBJ style winglets are offered as an optional feature for the -800

Bombardier CRJ900 ~ Iris & Posky

The CRJ900 is a stretched 76–90 seat version of the CRJ700. The aircraft features two GE CF34-8C5 engines, 59.4 kN (13,400 lbf) thrust with APR, and added leading edge slats. Max GTOW is 84,500 pounds. The airplane is loosely based on the CRJ200 series with a few major improvements. The environmental packs have a target temperature instead of a hot-cold knob. The cabin has a recirculation fan which aids in cooling and heating. The engines are controlled by FADEC digital engine control instead of control cables and a fuel control unit. The cabin floor has been lowered 2 inches which gains outward visibility from the windows in the cabin as the windows become closer to eye level height. The APU is a Honeywell RE220 unit which supplies much more air to the AC packs and has higher limits for starting and altitude usage. The wingspan is longer, the tail is redesigned with more span and anhedral. In typical service the CRJ900 can cruise 8–10,000 ft higher with a slightly higher fuel burn and an average true airspeed of 450–500 knots, a significant improvement over its predecessor. The FAA Type Certificate designation of the CRJ900 is the CL-600-2D24.

The first CRJ900 (C-FRJX) was modified from the prototype CRJ700 by adding longer fuselage plugs fore and aft; it was later converted into the prototype CRJ1000 by installing yet longer fuselage plugs

Embraer 170 (v3) ~ Dreamwings

The Embraer ERJ-170 and ERJ-190 series are all new entrants into the top end of the regional jet airliner market, with seating capacities spanning from 70 to 108.

Embraer announced the ERJ-170 and ERJ-190 in February 1999, and formally launched the program on June 14 that year at the Paris Airshow.

The first member of the family is the 70 seat Embraer 170, which rolled out on October 29 2001 (when the ERJ prefix was dropped for the marketing designation) and first flew on February 19 2002. Six aircraft were being used in the flight test program.

The public debut was at the Regional Airline Association convention at Nashville, Tennessee in May 2002, followed by its European debut at the Farnborough International Air Show in July the same year. The 170 was certificated in February 2004 and deliveries started in March 2004 to LOT Polish Airlines, US Airways and Alitalia Express.

Embraer is also building the Embraer 175, stretched by 1.77m (5ft 10in) over the Embraer 170. The first flight was made on June 14 2003.

The 6.25m (8ft 5in) stretched Embraer 190 seats 98 passengers, the further stretched Embraer 195, 2.41m (7ft 11in) longer than the 190, will seat 108. The Embraer 190 made the first flight in March 2004, followed by the 195 in December the same year.

All three variants are offered in standard and LR (long range) variants. A corporate jet version of the 170 is also proposed.

Features of the family include new FADEC equipped GE CF34 engines (the most powerful CF34 variants), a new four abreast "double bubble" fuselage cross section, a moderately swept wing with winglets (added to the design in mid 2000), fly-by-wire flight controls, and Honeywell Primus Epic EFIS avionics.

Although Embraer 170/175/190/195 are the marketing designations, the official type certificate designations remain ERJ prefixed as ERJ-170/175/190/195.
