Engine Performance Limit Weight Reductions
Takeoff & Landing Takeoff Obstacle/Enroute
Climb
PW 2000 (-200) 6,600 kg 10,200 kg
NOTE: Enroute climb weight reductions are computed for maximum lift-to-drag ratio speeds. For higher speeds, multiply the weight reductions by the factors listed in Section 3, General Notes, ENROUTE DIVERSION SPEED EFFECTS.
Increase V1 and VR by 1 knot.
If anti-ice valve is inoperative OPEN, ensure that the associated engine anti-ice switch is selected ON for duration of flight.
CAUTION: IF THE TAI VALVE IS LOCKED OPEN FOR DISPATCH, ENSURE THE VALVE IS CLOSED
DURING GROUND OPERATIONS WHEN THE ASSOCIATED PNEUMATIC DUCT IS PRESSURIZED BY THE APU OR GROUND CART AIR. THE VALVE MUST BE REOPENED PRIOR TO DISPATCH.
NOTE: The associated engine anti-ice switch-light will remain illuminated for the duration of flight if valve is inoperative open or closed.

EICAS STATUS MESSAGES
None
PLACARD
Anti-ice control panel as appropriate - L(R) EAI VLV LIGHT INOP
MAINTENANCE (M)
Prior to flight into icing conditions, verify operation of engine anti-ice valve as follows:
With electrical power on airplane, station observer
A. Access panels for the engine anti-ice valve are as follows:
Engine Side Access Panel
Left engine 414AR
Right engine 424AR
Turn affected anti-ice switch ON and then OFF. Ground observer should hear solenoid operate. If area
is too noisy to hear solenoid, it may be necessary to open access door or cowling.
Restore airplane to its required configuration.

EICAS STATUS MESSAGES
None
PLACARD
Appropriate probe heat light on Pilot’s Overhead Panel (P5) - HEAT LIGHT INOP MAINTENANCE (M)
If desired, Probe Heater functions may be verified as follows:
Apply electrical power to the aircraft.
WARNING: DO NOT TOUCH PROBES DURING TEST. SEVERE BURNS MAY RESULT.
CAUTION: DO NOT OPERATE PROBE HEATERS FOR MORE THAN 10 MINUTES. DAMAGE TO THE
PROBE AND HEATER MAY RESULT.
At miscellaneous test panel (P61), hold test switch in WINDOW/PROBE HEAT position. Hold hand near probe and check that probe is warming up. Release test switch.
