About the Bombardier CRJ900

The Bombardier CRJ900 is a short-haul regional jet that was first introduced in 2003. The plane has two turbofan engines with a maximum speed of 880 km/h. It also has a range of 2,500 km and can accommodate up to 90 passengers.

The CRJ900 is produced by Bombardier, a Canadian aerospace company. The plane is typically used for domestic and regional flights.

It has become a popular airline choice due to its fuel efficiency and low operating costs. The CRJ900 is part of the Bombardier CRJ series, including the CRJ100/200 and the CRJ700.

Why was it developed and built?

The Bombardier CRJ900 was designed to allow airlines to offer longer-range regional flights without investing in larger, more expensive aircraft. The plane also has a wide enough cabin to accommodate more passengers than the smaller CRJ700.

What purpose does the CRJ 900 serve?

It served and still serves several purposes, primarily as a regional jetliner for short-haul flights. It was designed to provide improved efficiency and comfort compared to its predecessor, the CRJ700. The CRJ900 was capable of carrying up to 90 passengers, making it ideal for mid-sized airports where larger aircraft could not operate. It typically worked on routes between major cities and secondary airports, providing an efficient way for passengers to travel between them.

About the McDonnell Douglas DC-9

It was initially produced by the developer company as the Douglas DC-9 until August 1967 and then by McDonnell Douglas. More than two thousand units were delivered to airlines around the world. The DC-9 has a stretched fuselage 6 feet (1.83 m) longer than the earlier MD-80.

The cabin windows are more oversized and rectangular than other Short Haul aircraft, giving every passenger a window seat. To further increase passenger comfort, the centers are aligned with the window so that all passengers have an aisle seat.

There are also bins above each seat for smaller carry-on items. Because of its popularity, the layout of the DC-9 has been used on many other aircraft, such as the Boeing 717 and Airbus A320 families. Despite its age, the DC-9 remains a famous aircraft due to its simplicity and low operational costs. It is also one of the most reliable aircraft, with a dispatch reliability rate of 99.3%.

Why was it developed and built?

The DC-9 was designed as an economical alternative to the larger, more expensive jet aircraft of the time. The smaller size of the DC-9 allowed airlines to operate it more economically than other aircraft, resulting in lower ticket prices for passengers. The DC-9 also had more oversized windows and seats than its competitors, giving it a comfortable interior for passengers.

What purpose does the DC-9 serve?

The DC-9 continues to be used by airlines worldwide as an efficient, reliable, and economical aircraft. It is well suited for short-haul routes of up to 1,600 km, with the ability to carry up to 136 passengers. The DC-9 is also known for its fuel efficiency and low maintenance costs, making it an excellent option for budget airlines.

How are the Bombardier CRJ 900 and McDonnell Douglas DC-9 different?
