FLAPS AND SLATS
The slats and flaps enable the aircraft to fly at lower speeds without stalling. On the other hand flaps and slats
increase drag and hence fuel flow. Thus, the flaps and slats are moveable to extend and retract them as
needed. The CRJ offers the following positions:

The Slat/flap Position Indicator is shown in degrees
on the engine display and is colour coded:
• Green: Normal operation
• White: Flaps disagree
• Amber dashes: Invalid data
The Slat/flaps Position Bar displays slat/flaps
deployment with the white markers as detents:
• Green: Normal operation
• White: Flaps disagree
• Amber dashes: Invalid or missing data
The Slat/flap Position Indicator is also shown in
degrees on the Flight Control display.
• Green: Normal operation
• White: Flaps/slats disagree
• Amber dashes: Invalid or missing data
Flaps lever controls the extension of slats and flaps, of course the standard FSX
controls can also be used. Please note the Emergency Flaps extension is not
simulated.
