44,000 lbs
What is the cargo compartment loading weight limited to?
3,500 lbs
What is maximum airport pressure altitude for takeoff and landing?
10,000 ft PA
What is the maximum operating altitude?
41,000 ft
What is the maximum ambient air temperature approved for takeoff and landing?
ISA +35 degrees Celsius
What is the minimum ambient temperature approved for takeoff?
-40 degrees Celsius
Why should you restrict your rotation rate to 3 degrees per second?
It can lead to excessively high pitch attitudes and angles of attack near the ground, leading to reduced stall margins resulting in stick shaker and pusher, and possibly loss of control.
On the ground, when must the cowl anti-ice be ON?
With OAT less than 10 degrees Celsius and visible moisture present, or operating on runways, ramps or taxiways with surface snow, ice, standing water or slush present.
On the ground, when the cowl and wing anti-ice are selected ON, what caution messages might be posted, and when should they disappear?
L (R) COWL A/ICE caution messages. They should disappear when engine thrust is increased. If more than 78% N2 is needed to extinguish the messages, then maintenance action is required.
In flight, when should cowl anti-ice be selected ON?
When TAT is 10 degrees Celsius or below, and visible moisture in any form is encountered (eg clouds, rain, snow, sleet, ice crystals), except when SAT is -40 degrees Celsius or below. It must also be switched on when ICE is annunciated by the ice detection system.
On the ground, when must wing anti-ice be selected on if Type II, III or IV anti-icing fluids have NOT been applied?
During final taxi prior takeoff (during single-engine taxi, this is considered the period after the second engine has been started), when the OAT is 5 degrees Celsius or below, regardless of weather conditions.
Why should thrust reverser use on wet and contaminated surfaces be avoided while taxiing?
Thrust reverser use in these conditions could result in wing contamination from reverse jet blast.
When must wing anti-ice be selected ON for takeoff, assuming Type II, III or IV anti-ice fluids have been applied to the wing? When exactly should this be done?
When the OAT reads under 5 degrees Celsius or below, and visible moisture in any form (clouds, fog, mist) is present below 400 ft, or the runway is wet or contaminated, or in the presence of any precipitation (snow, rain, sleet, ice crystals). The wing anti-ice should only be selected ON just prior to thrust increase for takeoff.
What other anti-ice system must always be selected ON when wing anti-ice is selected ON for takeoff?
Cowl anti-ice
In flight, when must wing anti-ice be selected on?
If the TAT is 10 degrees Celsius or below, and visible moisture in any form is encountered (clouds, rain, snow, sleet, ice crystals) except when the SAT is -40 degrees Celsius or below, or if the airspeed is less than 230 KIAS.
Are we permitted to operate the CRJ-200 in areas where SLD icing conditions exist?
No
How can one detect if the aircraft has entered an area where SLD icing exists?
Ice accretion on the flight compartment side windows.
What actions are necessary if ice accumulates on the flight compartment side windows?
Wing and cowl anti-icing must be selected ON in SLD icing conditions. Leave icing conditions as soon as possible.
Frost, ice, snow or slush adhering to any critical surface (wings, uper fuselage, horizontal stabilizer, vertical stabilizer, control surfaces and engine inlets) prohibits takeoff, except under what circumstances?
Takeoff is permitted with frost adhering to the upper surface of the fuselage, if it is possible to distinguish surface features (markings and lines). Frost in excess of this must be removed from the fuselage. In addition, frost on the underside of the wing fuel tank area that is caused by cold-soaked fuel is permitted, to a maximum thickness of 3 mm.
What are the necessary checks for detecting ice on the wing leading edge, wing forward upper surface, and wing rear upper surface during the external walkaround? When are these checks required?
A visual and a tactile check, necessary when the OAT is 10 degrees Celsius or less, the wing fuel temperature is 0 degrees Celsius or less, or the atmospheric conditions have been conducive to frost formation. Note that ice and frost may continue to adhere to wing surfaces for some time even at OATs above 10 degrees Celsius.
What requirements exist for pilot training when conducting a takeoff and the OAT is 5 degrees Celsius or less?
The pilot conducting the takeoff and the PIC must have had specific training within the last 12 calendar months for takeoff procedures, ground icing conditions and cold weather operations. If this cannot be met, wing anti-ice must be selected ON just prior to thrust increase for takeoff.
What are the maximum runway slopes approved for takeoff and landing?
+ or - 2%
What are the maximum tailwind components for takeoff and landing?
10 kts tailwind in either case.
What is the minimum flight crew of the CRJ-200?
One pilot and one copilot.
What colours denote maximum and minimum limitations, caution ranges and normal operating ranges?
Red, amber and green, respectively.
How long must engines be allowed to run prior to takeoff?
Two minutes
How long must engines be run at idle prior to shutdown?
At least two minutes to dissipate heat and stabilize internal operating temperatures.
May taxi time be included in the cool-down period prior to shutdown?
Yes, if the engine is at or below 80% N2
If the aircraft has been cold-soaked at an ambient temperature of -30 degrees Celsius or below for more than eight hours, what action is required prior to initiating start?
The engines must be motored for 60 seconds and fan rotation must be verified before start is initiated.
Under what conditions must the aircraft be exposed to for it to require that the engines must be motored for 60 seconds and that fan rotation must be verified before start is initiated?
The aircraft must have been cold-soaked at an ambient temperature of -30 degrees Celsius or below for more than eight hours.
What action is required of the thrust reversers if the aircraft has been cold-soaked at an ambient temperature of -30 degrees Celsius or below for more than eight hours?
Thrust reversers must be actuated until the deploy and stow cycles are less than five seconds.
