CRJ-700/900

December 9th, 2010

Expanding their regional jet aircraft line from the 50 seat CRJ100 and 200, Bombardier developed a new, larger series called 700, 705 and 900 in the late 90’s. The CRJ700 made his first flight in 1999 and in 2004 the first CRJ900 was delivered to Mesa Airlines. They are designed for 70 to 90 passengers and are available with different engines and tank configurations for different flight/range profiles. From a technical perspective and from the cockpit they have a lot in common and therefore they can be flown simultaneously in service by the type rated pilots.

CRJ700/900ER

The software simulates both CRJ700 and 900 aircrafts including variations like 705 with less passenger seating in the long fuselage. From the multitude of engines and range setups, we took the ones flown by the major airlines, which is the ER model. The major airlines real liveries will included. The specific differences of the CRJ700 and CRJ705/900 are represented in the external model and the cockpit with gauge arrangement and performance data.

Features:

  • Fully functional virtual cockpit with very smooth gauges and controls. Each cockpit variation represents the actual aircraft variant. FMC fully functional for real world navigation and updatable navigation database.
  • Full system simulation for electric, hydraulic, bleed systems. APU and anti-icing included.
  • Shared cockpit via direct or Internet connection.
  • Flight dynamics have been developed with active CRJ 700/900 rated pilots from 3 airlines. Specific testing in the simulator was used to verify specific aircraft behavior.
  • External/internal sounds recorded from actual aircraft.
  • Load Manager with %MAC calculation, exports a load sheet that can be seen in kneeboard.
  • Complete checklist from within the kneeboard.
  • Extensive documentation including 2 tutorial flights and 8 predefined flights

Exterior model

The exterior has been modeled in every detail with a lot of fine textures. Aircrafts variants differ in size and engines.

Full set of animations (control surfaces, elevator trim, doors, baggage compartments with variable loading, gear, extendable lights)

When parked, some exterior equipment is displayed.

Feature list:

  • All standard animations like control surfaces, elevator trim, gear, plus cargo doors and taxi and landing lights.
  • All doors can be handled separately
  • Exterior ground equipment, like power cable and wheel blocks.
  • Engine fans turning actuated from actual wind.
  • RAM Turbine simulation

Cockpit, avionics and systems

  • Extremely realistic 2D cockpit for all variants.
  • Main panel left and right seat, 2 full screen overhead panels, 3 full screen pedestal panels plus separate FMC, auxiliary panel. All panels include customized night lighting.
  • The instrumentation has been designed after each individual aircraft variant. They vary in the system included and their arrangement.
  • The FMC database includes the performance data from the real aircrafts.
  • Each plane variant has a fully functional virtual cockpit.

Feature list:

  • Different panel layouts for each variant.
  • Complete system simulation individually adapted.
  • Real engine start up procedure, with APU or external bleed air. Complete electrical distribution, every system is powered at is assigned bus.
  • Complete bleed air, air conditioning and cabin pressurization system
  • All internal and external lighting options.
  • Cabin pressurization system. Complete custom programmed VOR/ILS receivers, 2 VORs and 2 NDBs. Complete custom programmed clocks, RMI etc.
  • Head-up display, weather and terrain display with EGPWS and TCAS warnings
  • Complete FMS System, simulating the CRJ FMS Software
  • FMC contains special pages for loading/saving flight plans in DA format or MSFS format.
  • FMC contains special pages for individual loading/saving of panel state and individual copilot options.

Aerodynamics and performance

The realistic flight dynamics were developed in co-operation with different CRJ pilots from 3 different airlines. Fortunately we had all support from those pilots and we could fly many hours with them. Accurate airspeeds climb rates, fuel consumption and handling result in an authentic experience flying the virtual counterpart of a plane, which has specific performance and flying capabilities.

  • Accurate load sheet calculation with limits and CoG calculation for correct TO trim.
  • Wing anti-ice reduced engine performance resulting in either higher N1 or reduced climb rates.
  • Autopilot programming is tailor made and includes accurate control for pitch changes due to flaps motion. The original FMC performance databases have been implemented and represent accurate flight planning and execution.
