Sliding Entry-door Possible On CRJ1000?

The CRJ1000 is just launched and will not enter service for a while, so Bombardier has some time to make the aircraft really good for its customers. Many A.netters have commented that the CRJ 705/900/1000 are hardly "regional" jets as they regularly fly 3-4-hour-nonstops between big cities and many CRJs use jetbridges at airports already. Prospective customers might find that the CRJ1000 will have more appeal if it can lock on to a jetbridge straight away, like the E190, A320, B737 etc...

So, what do you think chances are that Bombardier will offer the CRJ1000 with a sliding entry door in addition to the existing drop-down door with stairs? The sliding-door-concept is already in use on the CRJ (the RH service/galley door) so this is nothing new to the aircraft type.

A sliding door without stairs will offer more usable room in the entry area during flight. A permanent FA-seat can be attached to the wall (like on E190) and the storage area behind can be expanded. Also, if slimline pax seats are installed the bulkhead can be removed and an extra row of seats can be installed on the LH side (Lo-Co-style where the front-row pax have their feet in the "vestibule area", like on Ryanair).

Opinions?

Hi crj900,

IMHO, i think that the CRJ series of aircraft 100 through 1000 series are all regional airliners, the narrow body and lacking of cargo capacity make it fall into another league than the larger jets, and talking about a sliding door, it should be made an option.

Fokker had this option available and you see Fokkers with sliding doors as well as integral airstairs...so it's whatever suits the customer...

regards,

I don't see why a sliding door isn't already available as an option on the CRJ family of a/c. Embraer made it one with the ERJs. At least with the ERJs, the a/c with swing down doors can still use a jetway without needing a gangplank between the jetway and the door.

I think that Bombardier should absolutely make a "stairless" door an option. I already don't see the CRJ 900 flying into podunk airports with no jetbridges, so I can hardly imagine that airlines would send the 1000 series to small airports. Perhaps Bombardier should even go as far to make a sliding door standard, with optional stairs that pull out similarly to those on the 737.

Or foldaway stairs like the Saab 340

Given the design and certification costs,I predict it'll have the same door as a 900. It's possible, but unlikely, IMHO.

Will it really be such a big project to turn the drop-down door into a sliding door? Will it not simply be a 40-50% larger version of the galley service door?

To a certain degree, yes. Obviously not that it can't be done if customers insist, but... aside from basic engineering and certification aspects (the added costs)... to have the option of a sliding door or airstair door would require substantial fuslage reinforcement to accomodate both door types and that would reduce payload.

Furthermore, since max commonality in design and manufacturing is desired across the 3 range of -700/900/1000 fuselages, substantially the same reinforced door structure would thus be carried in the smaller -700/900 also penalizing their payload.

When I was a flight attendant at mesa, it used to bug me on the 900s. The MCD is probably closer to three times the size of the service door in square inches, and in wieght its extremely heavy, it can't be closed manually from the FA position such as a dash 8, or CRJ200. I will say that the 900 is still a regional jet, simply because well...look inisde. The overhead bins are tiny, it seats two and two, it has no slides, everything about that plane is regional except its "mainline" length. Even the egines are RJ engines...

Why is the CRJ900 door heavier than the CRJ200 door?

Actually EMB does not own the STC for the plug door on the 145. I think Xpress Jet does. So it costs more to install a plug door on factory build planes because XpressJet takes a royalty from every EMB sale that uses that design.

can lock on to a jetbridge

Jetbridges (jetways) do not lock on the the aircraft, they just butt up next to them, there is no physical connection.

You must be strong to be able to close the MCD on a crj-200 from the inside without the power assist. I have yet to see anybody do it without the assistance from an person on the outside.

I do think if it were made an option that airlines would buy it, and I think if it were made an option on the 900 you would also see some takers.
