    Momentary deviations up to -50°C do not require maintenance action.
  31. 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.
  32. 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.
  33. Operation in Icing Conditions

    Minimum Temperature for Manual Anti-icing Operation
    -40°C

    NOTE

    A 1/8th inch frost layer is permitted on the underwing surfaces.

    Frost is not permitted on the lower or upper surface of the horizontal stabilizer or the upper surface of the wing.
  36. Takeoff on Contaminated Runways (AC 25-13)
    If the Captain determines that the runway of intended use is “Contaminated”, the Automated Performance Analyst procedures contained in the EMB AOM Volume 1 Performance Section must be used.

    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:
    • standing water
    • slush or
    • wet snow
    • More than 3/4 inches (19 mm.) of dry snow
    • Compacted snow
    • Ice
  37. Pre-takeoff Tactile Check
    • There are many methods to ensure the wing is clear of ice. If visual inspection does not indicate wing contamination, a tactile (hand on surface) check of the wing leading edge and the upper surface must be accomplished prior to takeoff.
    • The tactile check must also be performed when the holdover time is exceeded after airplane de/anti-icing fluids are applied. This check should be performed whenever the outside temperature is 5°C or below and:

    • there is visible moisture; or
    • water is present on the wing; or
    • the difference between the dew point and the outside air temperature is 3°C or less; or the atmospheric conditions have been conducive to frost formation.

    • NOTE
    • If these conditions are anticipated to occur prior to takeoff, this procedure shall be accomplished during the preflight inspection.

    • NOTE
    • DO NOT USE APU BLEED AS PNEUMATIC SOURCE FOR ANTI-ICING SYSTEM.

  90. FMS

    General

    The following limitations apply only to navigation with the FMS:
    • The aircraft must have other navigation equipment installed and operating, appropriate to the route of flight.
    • The FMS-Unilink Operating Manual, must be immediately available to the flight crew whenever navigation is predicated on the use of FMS. An electronic copy is acceptable.
    • Universal FMS Software version 603.5 (or later approved version) must be installed.
    • FMS PVOR outbound function is prohibited.
    • When flying to an airport where GPS stand-alone is the intended and only suitable approach, prior to dispatch, the flight crew is required to verify that the predictive RAIM at the destination ETA +/- 15 minutes for all values are within the approach criteria.
    • GPS-based instrument approach procedures may be planned for use at destination or alternate airports, but not for both. When the approach at the destination is based on GPS and an alternate airport is required by the applicable operating rules, the alternate airport must be served by an approach based on a navigation aid other than GPS. The navigation aid must be operational and the aircraft must have operational equipment capable of using that navigation aid (OpSpec C055).
  91. FMS

    Approach Limitations
    • GPS instrument approaches must be conducted in the FMS approach mode, and GPS integrity monitoring must be available at the Final Approach Fix, as indicated to the pilot by the INTEG amber annunciator being off and the APP blue annunciator displayed on the PFD.
    • Use of FMS guidance for conducting instrument approach procedures is prohibited when the FMS is operating in the dead reckoning mode (DR annunciation set on PFD).
    • The pilot must review the complete transition-approach, comparing the way points and altitudes displayed on the FMS with those on the published procedure prior to activation to insure that the correct procedure and transition are selected.
    • When using FMS guidance for conducting instrument approach procedures that do not include a GPS reference in the title of the published procedure (Non-Overlay approaches), both pilots must verify that the procedure specified navaid and associated avionics are operational, and the conventional navaid data shall be displayed on the PM’s PFD.
    • Once the aircraft is fully configured for an approach, FMS messages shall not be retrieved from the FMS CDU. Local alerts on the PFD will alert the crew to a loss of RAIM or required approach scaling tolerances. Messages can be retrieved once completing the approach segment.
    • ILS, LDA, SDF, NDB and MLS approaches, using the FMS for guidance, are prohibited. Transition segments to an ILS can be flown using FMS guidance.
  92. FMS

    Database
    • IFR enroute and terminal navigation is prohibited unless the pilot verifies the currency of the database and verifies each selected waypoint for accuracy by reference to current approved data. If the database is expired, an AML entry is required.
    • FMS Instrument Approaches must be accomplished in accordance with the Instrument Approach Procedures that are retrieved from the FMS navigation database. The FMS database must incorporate the current update cycle.
    • Pilot defined instrument approaches may not be conducted.
    • Envoy Special Visual Approach Procedures are not considered pilot defined approaches.
    • The fuel flow and fuel used presented on the FMS are supplementary information only. The flight crew must use fuel information primarily from the MFD and EICAS display.
  93. FMS

    Geographic Limits
    • During enroute and terminal area operation with DR annunciated on the PFD, the flight crew must verify the FMS position using VOR/DME raw data or other appropriate means.
    • IFR Non-Precision Approach approval is limited to published approaches within the airspace of countries operating under FAA jurisdiction. Approaches to airports in other airspace are not approved unless authorized by the appropriate governing authority.
    • Operation above 73° North Latitude and below 60° South Latitude is prohibited due to unreliable magnetic heading.
  94. FMS

    Missed Approach
    FMS Missed Approach using the CDU Mode Select Buttons is prohibited.
  95. FMS

    Vertical Navigation (VNAV)
    • VNAV is advisory only, and the altimeter shall be the primary source of altitude information at all times.
    • Coupled FMS vertical guidance is not available. Therefore, during FMS operation with Autopilot coupled, the pilot must use the Flight Guidance Controller for vertical control. Advisory vertical guidance is available only in descent.
  96. Fuel

    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.



  111. Miscellaneous

    Cockpit Security Door
    • On airplanes equipped with a cockpit security door, two crewmembers must be in the cockpit during all flight phases.
    • If one of the pilots leaves the flight deck, he must be replaced in the cockpit by another crewmember.
    • Positive identification of the person wishing to enter the flight deck must be obtained before opening the door.
    • The security cockpit door must be kept closed and locked at all times during flight except to permit access and egress.

    • Note
    • This limitation is not applicable while performing Ferry Flights, provided no passengers are on board.
