Limitations

Question 1

Unpressurized Flight

Maximum Altitude for operation after an in flight depressurization is …

Answer 1

10,000 ft. MSL unless MEA or other constraints require a higher altitude.

Question 2

Maximum Allowable Airspeed

Question 3

Maximum Allowable Airspeeds (Cont.)

Answer 3

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 verticle stabilizer or the rudder.

Note

* Momentary airspeed excursions that re 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

Question 4

Altitude

Maximum Operating Altitude.

Answer 4

37,000 ft.

Maximum Takeoff and Landing Pressure Altitude…………………………………………………………-1,000 ft.

Maximum Takeoff and Landing Pressure Altitude………………………………………………………….8,000 ft.

Question 5

Temperature

Answer 5

Takeoff and Landing Temperature Limits

Maximum………………………………………………………-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.

Question 6

Icing Definitions

On the Ground and for Takeoff

Answer 6

Icing conditions exist when the OAT 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).

Icing conditions also exists when the OAT is 10 C or below 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 visible 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.

Question 7

Icing Definition

In Flight

Answer 7

Icing conditions may exist whenever the 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).

Question 8

Operating in Icing Conditions

Answer 8

Minimum Temp for Manual Anti-Icing Operation….-40 C

Maximum Temp for Manual Anti-Icing Operation… 10 C

Note

• Use Stable 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.

Question 9

Contaminated Runways

Answer 9

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 (3mm) of:
  
  • standing water
  • slush or
  • wet snow
• More than 3/4 inches (19mm) of dry snow
• Compacted snow
• Ice

Question 10

Autopilot

Answer 10

Minimum Disengagement Height ………………….. 500 ft.

Minimum Disengagement Altitude:

• Inst Appr (APR or NAV mode) ………… MDA/DA/DH
• Visual Appr (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.

• Single engine go-around with auto-pilot engaged is prohibited.
• Approach mode selection during localizer capture is allowed only when aircraft is inbound.

Question 11

Yaw Damper

Answer 11

Yaw Damper operation is not authorized for:

• Takeoff to 500 ft. AFL.
• Landing

Question 12

APU Starter Limits

Answer 12

Cooling period:

Between Three Consecutive Attempts …….. 1 min. OFF

Between Two Series of Three Consecutive Attempts …………………………………………………………………… 30 min. OFF

Question 13

Attitude and Heading Reference System (AHRS)

Answer 13

The aircraft must not be moved when the AHRS is in the initialization mode until all altitude and heading information presented on the PFD is displayed.

Question 14

Engine Cool Down After Landing or High Power Runs

Answer 14

Run each engine for a minimum of one minute at idle or taxi thrust before shutdown.

Question 15

Engine Oil Level

Answer 15

The minimum dispatch oil quantity is eight quarts before Engine Start or seven quarts after Engine Start.

Question 16

Engine Warm Up Prior to Takeoff

Answer 16

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.

Question 17

Rolls Royce AE3007 A1, A1/3 Operating Limits

Answer 17

Op. Conditions ITT (C) N₁ (%) Max N₂ (%) Max

T/O-1 {A1]

Question 18

Rolls Royce AE3007 A1, A1/3 Operating Limits

(Cont.)

Answer 18

Note

3. Engines may operate in the amber range up to 115 psi for five minutes in all thrust modes. Operations in the amber range above 115 psi up to 155 psi is permitted for up to two minutes. Total time in amber range may not exceed five minutes. Operation in the red range is not authorized for any aircraft. Any exceedance must be monitored and logged in the AML by the crew.
4. Minimum oil temperature for starting is -40^o C.

Minimum oil temperature for takeoff is 40^o C. If oil temperature is less than 40^o C, perform Engine Warm Up Prior to Takeoff Procedures located in AOM.

Question 19

Question 23

Reverse Thrusters

Answer 23

• 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 critical and its use will prevent a runway excursion.
  • When landing on runways with “Medium” or “Poor” braking action, uless 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.
