Hi fellow wiki editors!

To help newly registered users get more familiar with the wiki (and maybe older users too) there is now a {{Welcome to the wiki}} template. Have a look at it and feel free to add it to new users discussion pages (and perhaps your own).

I have tried to keep the template short, but meaningful. /Johan G

The Bombardier CRJ700 series is a family of 70- to 100- seat regional jet airliners manufactured by Bombardier Aerospace. Its primary competition is the Embraer E-jet series. The family consists of the Bombardier CRJ700, CRJ900, and CRJ1000. The CRJ700 series was developed from the Bombardier CRJ200, and remains one of the most popular regional airliner series in the world.

Aircraft of the Week/Month

The CRJ700 was reviewed by Thorsten R as part of the "Aircraft of the Week/Month" feature on the FlightGear Forums.

Model

The 3d cockpit of the CRJ-700 is very detailed and contains not only functionality on the main panel but also on the central console and an overhead panel. However, as often seen, the cockpit surfaces not covered by instrumentation are very simply textured by a monochromatic grey color - a more natural texture resembling a real material with some wear and tear could add a lot here.

There is a lot of functionality in the cockpit - a startup procedure using the APU is supported as well as a full set of external lights and no-smoking and seat belt signs for the passengers. A nice touch of the model is that it also contains an interior view of the cabin in which the signs can be observed. Switches and knobs are usually animated, and the clickspots are placed fairly intuitively. The MFD's all have various selectable functions.

The exterior model of the aircraft is also very nicely done, contains good animations and shows all the light switch settings in the cockpit faithfully. An option to switch livery exists as well.

Flight characteristics

The FDM of the CRJ-700 is quite plausible for an airliner of its size. I haven't really tested the behaviour at the edge of the performance envelope, but during normal operations, the plane behaves well and reaches basic performance characteristics. All in all, the plane is an airliner (albeit a small one) - it turns slowly, it does not descent rapidly without picking up a lot of excess speed and all maneuvers need to be planned well in advance. Having said that, it's actually fun to fly.

I found the AP nicely tuned and able to fly turns, climb or dive at all altitudes without oscillations or weird behaviour. Unfortunately, the support for AP modes involving navaids is not as good: While I could home in on a VOR station, the AP seems to be tracking the station rather than the chosen radial, i.e. the angle under which I approached the station kept changing. Also, I was unable to intercept an ILS glideslope automatically. However, the plane can be operated well in IFR conditions just using the instruments to display the navaid signals and the heading and altitude modes of the AP to control the plane.

My personal wishlist

Fixing the AP to a more consistent behaviour with navaids would be high on my priority list - there are currently very few airliners with a well-tuned AP capable of tracking navaids. Some more natural texturing in the cockpit would also be nice. I realize that the CRJ-700 is a fairly recent addition to the aircraft repository of Flightgear - but I like where the model is going very much.

Things to experience

Try flying at night - the CRJ-700 has one of the best light concepts I've ever seen. The instrument lights are very beautifully done and can be dimmed at need, the cabin lights likewise, and all lighting is visible both from internal and external views.


Editor's note: The autopilot VOR-LOC/ILS holds have been fixed as of CRJ700 v1.0.2.
