Difference Between CRJ-705 And CRJ-900

Thu Nov 09, 2006 4:25 am

Hi everyone,

can anyone tell the exact differences between the CRJ-705 and CRJ-900 series? I thought it all would come down just to the question if there's a First/Business class (705) or not (900), but SkyWest calls its planes CRJ-900 despite having a First class section...

If I remember correctly, they are the same size but they are each certified to fly so many passengers (76 for the 705 & 86 for the 900?). This was to help the scope clauses I believe and to get better performance for the 705. Please correct me if I am mistaken.

there really is no difference between the 705 and the 900. Seating is it. But a 73G is a 73G no matter how you configure the seating.

The name CRJ-705 originally came about from a joint effort of Bombardier and USAirways to get around the USAirways pilot contract which limited RJ flying to CRJ-700s. They intended for it to mean a 70 seat RJ. (the E-170 was around at the time, but was not really to be outsourced, instead was to be flown by USAirways pilots for MidAtlantic) Poorly written scope, but that was the intent. Management decided to try and get around that and fly a larger RJ by getting Bombardier to come up with a version called the -705. But a 705 is just a 900 by a different name.

Look it up. There are no external differences between the 705 and the 900. So why is it not called a 905?

The aircraft is certified as a -900, but until the Delta pilots ratify a new scope-clause, the aircraft will remain at 70 seats.

The aircraft is a 900. The pilots scope is certified as per the new contract, but DCI cannot fly a 76 seater until Jan 07, so until then Skywest is flying the -900 at 70 seats.

not really, you said the pilot's new scope had to be ratified. The entire contract was ratified back in the early summer.

The real difference is that the 705 is certified for only 75-pax and an airline can't increase the seating (just like the CRJ440). And therefore it is also cheaper than the 900.

There is a physical change to the aircraft! The winglets are different on the -705 than on the -900's. They look longer and seem to have more of an angle to them.. Take a look

You're correct in where the name came from, but the scope clause in the US-ALPA contract was written just fine. Management did pulling a fast one as you said by calling it a "CRJ-700, Series 705", but the scope clause in fact contained MTOW limits that the -705 was too heavy for, and ALPA called them on it, hence US having to switch its order to the -701.

The designator was in fact to meet the scope clause for ACjazz and Air Canada, hence ACJazz being the 1st to operate them (705 series)...
You can't get there from here.

No, it wasn't. Jazz being the first to operate them is completely irrelevant.

Jazz placed their order on September 27, 2004.

The designator was created for US Airways, who placed their order on May 12, 2003, well over a year before the Jazz order.

Heck, US *cancelled* their -705 order on July 9, 2003, still over a year before the Jazz order.

Not any more. MESA is the only CRJ900 operator with the "original" winglets, IIRC, as the -705 winglets are now standard on all new-build CRJ900 delivered to all other -900 operators, because they offer better economics and aerodynamics.
