Q

JFK 31L has 3 RVR reports: TDZ/MID/ROLLOUT. If reported RVR is 5/4/5, are we allowed to take off. If reported RVR is 5/inop/5 are we allowed to takeoff?

A

No/yes

  • if RVR is more than 1600 RVR
    - the TDZ RVR report is controlling
    - the MID RVR report may be substituted for an unavailable TDZ report
  • If RVR is less than 1600 RVR
    - min of 2 operative RVRs
    - all reporting RVRs are controlling

Q

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

A

Reference opspec C055: Alt airport IFR wx minimums

We use the 1 NAVAID/2 NAVAID rule to derive alternate wx minimums.

 -1 NAVAID: for airports with at least 1 operational navigational facility providing a straight in NPA or cat 1 precision approach, or, when applicable, a circling maneuver for an IAP. 
   Add 400’ to MDA or DA 
   Add 1 sm to landing minimum

2 NAVAID: for airports with at least 2 operational navigational facilities each providing a straight in approach to different suitable runways
Add 200 to DA/MDA of the 2 app used
Add 1/2 sm to the higher authorized landing minimum of the 2 approaches used

Q

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

A

No. An alternate is an alternate. We always reference C055

17
Q

Can we apply exemption 3585 to a destination or 2nd alternate?

A

Yes.
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 C055 derived alternate weather minimums.

2nd alternate: forecast must indicate in the main body and conditionals that the forecast ceiling and visibility at the 2nd alternate at ETA will be at or above the C055 derived alternate weather minimums

18
Q

With 2 alternates listed in the release, what is the required minimum fuel?

A

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 min at normal cruising consumption

19
Q

You are planning for an ILS 27 with published minimums of 1/2sm -1800 RVR. Prevailing visibility is 3/4 sm and TDZ RVR for 27 is 1600 RVR. Can you start the final approach segment? Can you continue if inside the FAF?

A

No, whenever RVR is reported for a particular runway, it becomes the controlling visibility for the runway.

Yes, if inside the FAF the wx is reported below minimums you can continue the approach

20
Q

Which RVR report is controlling for approach and landing?

A

Reference C052

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. MID RVR may be substituted for TDZ RVR in the event TDZ RVR is not available

21
Q

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

A

DDA - derived decision altitude

22
Q

How is DDA determined for an RNAV approach?

A

Add 50’ to the MDA

23
Q

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

A

Reference C052

The certificate holder may not use DA(H) unless paragraph C073 is authorized, which C073 is not authorized.

24
Q

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?

A

Reference C052
Must be equipped with F/D or A/P
Requires to use the F/D or A/P during approach to DA

25
Q

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

A

No

26
Q

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

A

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

27
Q

What are the elements of a stabilized approach?

A

All of the following are achieved before or upon reaching stabilization height:

  • aircraft is in the correct lateral and vertical flight path
  • only small changes in heading and pitch
  • aircraft is in desired landing config
  • thrust is stabilized usually above idle
  • the landing checklist and briefing complete
28
Q

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

A

Less than or equal to 1,500’ ceiling and 5sm visibility: 1000’

Greater than 1,500’ ceiling and 5sm visibility: 500’

29
Q

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

A

Go around unless crew indicates only small corrections are necessary

30
Q

When do captain high minimums apply?

A

Captains who have less than 100 hrs PIC under part 121 in the aircraft type being operated

31
Q

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

A

100’ and 1/2 sm

32
Q

So high minimums captain requirements apply to the alternate?

A

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

33
Q

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

A

75 hours of line operating flight time as pic/sic with Allegiant on type.

Captains: 100 hours as PIC with Allegiant on type

34
Q

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

A

The PIC or SIC must have 75 hours of line operating flight time, either as pic or sic in type

35
Q

What is required for consolidation of knowledge and skills?

A
  • PIC and SIC crewmembers must accrue at least 100 hours of line operating flight time to complete consolidation
  • must be completed 120 days from the completion of type ride or PC
  • if the requirement has has been met as an SIC then it is not required at upgrade
  • includes credit for OE
  • can be extended for 30 days
36
Q

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

A

The captains must make all the takeoffs/landings if:

  • at a special airport
  • vis at or below 3/4 (4000 RVR)
  • contaminated runway
  • crosswind greater than 15kts
  • windshear
  • captains discretion
37
Q

When is an aircraft security search required to be completed?

A
  • Prior to the beginning of each calendar day
  • if aircraft left unattended
  • prior to each departure to/from international (except Canada)
  • when there is a reasonable cause due to breach of security
38
Q

What is the standard Allegiant clearance from thunderstorms above FL230?

A

20nm

39
Q

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

A 
Red or yellow emergency 
TEST briefing (red emergencies)
T: type of emergency 
E: evacuation type and probability 
S: signals to be used for bracing/evac
T: time available
40
Q

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?

A

“This is the captain, remain seated” or “standby, standby, standby”
