A ceiling of less than 500’ above DA(H) or MDA(H) or o A visibility of less than ½ mile above the lowest

How do you determine that the alternate listed on the release is legal?

º Reference Ops Spec C055: Alternate Airport IFR Weather Minimums
º We use the 1 NAVAID/2 NAVAID rule to derive alternate weather minimums.
§ 1 NAVAID: for airports with at least 1 operational navigational facility providing a straight-in NPA, or
Category 1 precision approach, or, when applicable, a circling maneuver from an IAP:
• Add 400 ft to MDA(H) or DA(H), as applicable
• Add 1 SM to the landing minimum
§ 2 NAVAID: for airports with at least 2 operational navigational facilities, each providing a straight in
approach procedure to difference suitable runways:
• Add 200 ft to higher DA(H) or MDA(H) of the 2 approaches used
• Add ½ SM to the higher authorized landing minimum of the 2 approaches used

Would we use a different method to determine if the takeoff alternate or second alternate weather is legal?

No. An alternate is an alternate, we always reference C055.

Can we apply exemption 3585 to a destination or second alternate?

º Yes
º First alternate: The main body of the TAF must forecast a ceiling and visibility value at the ETA for the first alternate equal to or greater than the C055 derived alternate weather minimum ceiling and visibility. A conditional statement must not forecast a ceiling or visibility, at the first alternate ETA, that is less than ½ of the derived alternate weather minimum ceiling or visibility.
º Second alternate: Forecast must indicate in the main body and conditionals that the forecast ceiling and visibility, at the second alternate at ETA, will be at or above the C055 derived alternate weather minimum ceiling and visibility.

With 2 alternates listed on the release what is the required minimum fuel (domestic)?

º Fuel, at the time of takeoff:

Fly to and land at the airport the flight was dispatched or released, and then
Fly to and land at the most distant alternate airport, and then
Fly for 45 minutes at normal cruising consumption.

You are planning for an ILS to RWY 27 with published minimums of ½ SM-1800 RVR. Prevailing visibility is
¾ SM and TDZ RVR for RWY 27 is 1600 RVR. Can you start the final approach segment? Can you continue if
inside the FAF?

º No, whenever RVR is reported for a particular runway, it becomes the controlling visibility measurement for
operations on the runway.
º Yes, if inside the FAF the weather is reported below minimums you can continue the approach.

Which RVR report(s) is controlling for approach and landing?

º Reference C052
º TDZ reports, when available for a particular runway, are controlling for all approaches and landings for that
specific runway. The MID RVR and ROLLOUT RVR reports (if available) provide advisory information to the
pilots.
Note: The MID RVR report may be substituted for the TDZ RVR report in the event TDZ RVR report is not
available.

If you are flying an NPA what do you enter in the MCDU PERF Approach page for minimums?

DDA: Derived Decision Altitude

How is DDA determined for an RNAV (GPS) approach?

DDA is derived by adding 50’ to the appropriate LNAV MDA(H).

Why don’t we use LPV or LNAV/VNAV minimums?

º Reference C055-3 LNAV only.

º The certificate holder may not use DA(H) unless paragraph C073 is authorized. C073 is NOT AUTHORIZED.

What is required when flying an ILS approach with a report of 1800 RVR if the runway does not have operative TDZ lights or RCL lights? GOM 11.4.8.20

o Reference C052; Must be equipped F/D or A/P o Required to use the F/D or A/P during the approach to DA

If you are flying an RNAV (GPS) approach and lose “GPS primary” inside the FAF can you continue the approach?

No, the approach must be discontinued.

If you are flying a VOR approach and lose “GPS primary” inside the FAF can you continue the approach?

Yes, raw data is required to be displayed and monitored during the approach. If flight remains within required tolerances for the approach, then the approach can be continued.

What are the elements of a stabilized approach?

º An approach is considered stabilized only if all of the following elements are achieved before or upon reaching the applicable stabilization height: * The aircraft is in correct lateral and vertical flight path (based on NAVAID guidance or visual references). * Only small changes in heading and pitch are required to maintain this flight path. * The aircraft is in the desired landing configuration. * The thrust is stabilized, usually above idle, to maintain the target approach speed along the desired final approach path. * The landing checklist has been accomplished as well as any specific briefing.

What are the minimum HAA stabilization altitudes based on meteorological conditions?

º Meteorological conditions HAA: * Less than or equal to 1,500 ft ceiling and 5sm visibility: 1,000 ft * Greater than 1,500 ft ceiling and 5sm visibility: 500 ft

What is the proper action if the minimum stabilization height is not met?

If the aircraft is not stabilized on the approach path in landing configuration at the minimum stabilization height, a go-around must be initiated unless the crew estimates that only small corrections are necessary to rectify minor deviations from stabilized conditions due to external disturbances.

When do captain high minimums apply?

High minimums apply to captains who have less than 100 hours PIC under Part 121 in the aircraft type being operated.

What are you required to add to weather minimums at your destination as a high minimums captain?

100’ and ½ SM

Do high minimums captain requirements apply to the alternate?

No. The published minimums apply or 300-1, whichever is higher.

What are the notification requirements for a low time pilot? High minimums captain?

At the beginning of each duty period, each pilot must contact dispatch if he has not accrued: º 75 hours of line operating flight time as PIC/SIC, with Allegiant, on type. º Captains: 100 hours as PIC, with Allegiant, on type.

Describe the “green-on-green” pairing limitation?

The PIC or SIC must have 75 hours of line operating flight time, either as PIC or SIC in aircraft type. Note: This pairing limitation does not apply to a new captain who has greater than 75 hours of line operating flight time in type as first officer.

Explain what is required for Consolidation of Knowledge and Skills?

º PIC and SIC crewmembers must accrue at least 100 hours of line operating flight time to complete consolidation. º Must be completed 120 days from the completion of type ride or PC. º If the requirement has been met as an SIC then it is not required at upgrade. º Includes credit for OE º Can be extended for 30 days

What are the limitations on first officers flying with less than 100 hours time in type?

º The captain must make all takeoffs/landings if: 1. At a special airport 2. Visibility is at or below ¾ SM (4,000 RVR) 3. Contaminated runway (braking action less than good) 4. Crosswind greater than 15kts 5. Suspected/reported windshear 6. Captains discretion 1t. Captain may allow first officer to manipulate the controls in all phases of flight, if before takeoff, the captain conducts a pre-takeoff briefing to review each crewmembers’ duties. 2. First officers are responsible for ensuring the captain is notified when they have not completed consolidation.

When is an aircraft security search required to be completed?

º Prior to beginning of each calendar day º If aircraft left unsecured/unattended º Prior to each departure to/from an international destination (Canada is the exception) º When there is reasonable cause due to breach of security or a specific threat

What is the standard Allegiant clearance from thunderstorms above FL230?

20nm

What briefing will the Captain give the LFA in an emergency situation?

``` º Red or Yellow Emergency º T-E-S-T Briefing (for Red emergencies) § T: Type of emergency expected § E: Evacuation type and probability § S: Signals to be used for bracing/evacuation § T: Time available and R: Have FA Read Back. ```

In an abnormal/emergency situation after the aircraft is stopped on the runway, what are the 2 commands the captain shall use to communicate to the passengers and flight attendants?

º “This is the Captain, Remain Seated” or | º “Standby, Standby, Standby”
