Caution
4. A full or nearly full rudder deflection in one direction followed by a full or nearly full deflection in the other direction, even at speeds below the design maneuvering speed, can dramatically increase the risk of structural failure of the vertical stabilizer or the rudder.
- *Momentary airspeed excursions that are due to wind gusts or turbulence are allowed up to 155 kts. with no crew or maintenance action required.
*Steady state operation over 145 kts. is not allowed and must be entered into the AML.

Takeoff and Landing Temperature Limits:
Minimum Temp.
-40°C SAT
-
NOTE
In the event of a landing below -40°C SAT, the aircraft may not takeoff without further maintenance inspection.
TAT in cruise flight above 25,000 ft. is limited to -45°C.
Momentary deviations up to -50°C do not require maintenance action.

Anti-ice/Deice
Icing Definitions
On the Ground and for Takeoff
Icing conditions exist when...
- OAT is 10°C or below
- visible moisture in any form is present
- clouds, fog, rain, snow, sleet and ice crystals
when operating on ramps, taxiways or runways where surface snow, ice, standing water or slush may be ingested by the engines, or freeze on engines, nacelles or engine sensor probes.
CAUTION
On the ground, do not rely on visual icing evidence or ice detector actuation to turn on the Anti-icing System. Use the temperature and visual moisture criteria as specified above. Delaying the use of the Anti-icing System until ice build-up is visible from the cockpit may result in ice ingestion and possible engine damage or flameout.
-
Anti-ice/Deice
Icing Definitions
In Flight
Total Air Temperature (TAT), is 10°C or below and visible moisture in any form is present (such as clouds, fog with visibility of one mile or less, rain, snow, sleet and ice crystals).
CAUTION
Notwithstanding ice detector monitoring, the crew remains responsible for monitoring potential icing conditions and for manual activation of the Ice Protection System if icing conditions are present (known icing) and the Ice Detection System is not activating the Ice Protection System.

Operation in Icing Conditions
Minimum Temperature for Manual Anti-icing Operation

-
Operation in Icing Conditions
Maximum Temperature for Manual Anti-icing Operation

NOTE
Use Static Air Temperature (SAT) on the ground or for takeoff.
Use Total Air Temperature (TAT) for operations in flight.
NOTE
There is no temperature limitation for automatic Anti-icing System operation.

Takeoff on Contaminated Runways (AC 25-13)
A runway is considered “Contaminated” when more than 25% of the required field length, within the width being used, is covered by
- More than 1/8th inch (3 mm.) of:
- Wet Snow
- Slush or
- Standing Water
- More than 3/4 inches of Dry Snow
- Dry Snow
- Compacted snow
- Ice
-
Autopilot
Minimum Engagement Height

-
Autopilot
Minimum Disengagement Altitude:
Instrument approach (APR or NAV mode) use MDA/DA/DH
Visual approach (HDG or NAV as noted)..Traffic pattern altitude (1,500 ft. AFL)
- NOTE
- Visual approaches may be conducted in NAV mode when authorized by an Envoy Special Visual Approach Procedure in Flight Manual - Part 2.
- The autopilot must be disconnected below 1500 ft. AFL
-
Autopilot
Single engine go-around with autopilot engaged is
Prohibited.
-
Autopilot
Approach mode selection during localizer capture is allowed only...
When aircraft is inbound.
NOTE
CAT I ILS Coupled go-around height loss may be 95 ft.
-
Yaw Damper
Yaw Damper operation is not authorized for:
- Takeoff to 500 ft. AFL
- Landing
-
Attitude and Heading Reference System (AHRS)
The aircraft must not be moved when the AHRS is in the initialization mode until all attitude and heading information presented on the PFD is displayed.
-
Engine
Engine Cool Down After Landing or High Power Runs
Run each engine for a minimum of one minute at idle or taxi thrust before shutdown.
-
Engine
Minimum Dispatch Engine Oil Level before and after engine start
The minimum dispatch oil quantity is eight quarts before Engine Start or seven quarts after Engine Start.
-
Engine
Engine Warm Up Prior to Takeoff
The engines must be allowed to run at low thrust to stabilize engine temperatures before takeoff thrust is selected. Run the engine at idle or taxi thrust a minimum of four minutes for cold engines and two minutes for warm engines. An engine is considered cold if it has been shutdown for more than 90 minutes.
Prior to increasing N2 above 83% , the engine oil temperature must be a minimum of 40°C. In lieu of this minimum oil temperature limit, it is acceptable to run the engine for at least eight minutes and ensure the oil temperature is in the green range prior to advancing the Thrust Levers for takeoff.

Thrust Reverser Use
- Thrust reversers are intended for use during rejected takeoff or landing only.
- After initiating reverse thrust, a full stop MUST be made. MAXIMUM reverse thrust MUST be used:
- Whenever stopping distance is deemed to be critical and its use will prevent a runway excursion.
- When landing on runways with “Medium” or “Poor” braking action, unless the appropriate landing distance penalty [Flip Cards] is applied.
- IDLE reverse MAY be used on:
- Dry runways 7,000 ft. or shorter usable length (LDA)
- Non-dry runways where braking action is “Good”
- Thrust reverser use is PROHIBITED for:
- Power-back operations
- Taxi operations
- Thrust levers stabilized in any intermediate position between IDLE reverse and MAXIMUM reverse.
