Q

what are the requirements for a departure alternate:

  • (distance from departure airport)
  • (weather requirements)
A
  • distance:
    within 1 hour flight time in SEO, still air, estimated takeoff weight (430nm)
  • weather conditions:
    no relevant weather forecast below the landing minima (considering SEO)
    note: INTER/TEMPO PROB 30/40 periods are not relevant

Q

when is a destination ALTN required

A
  • Ceiling: MDA for planned approach + 1000’ OR CIRCLING approach + 500’ if circling
  • Visibility: higher of:
    • VIS for planned approach + 2000m; OR
    • 5000m
  • Lighting:
    • portable - unless RP
    • NO STBY - RP with portable lights
    • PAL AND STBY - RP to manually switch them on
      note: light requirement for RP from ETA-30mins to completion of taxi OR first light+10mins
      not required if HOLD FUEL carried for first light+10mins

Q

what are ALL the conditions required to apply the TAF3 rule

A
  • within 1 hour flight time of intended DEST
  • TAF3 appended to forecast
  • ETA -30/+60 wholly contained within the TAF3 validity period
  • ETA -30/+60 = NO relevant weather < 4.11 table (200’/800m OR 400’/circling & 800m/circling OR LSALT+500’/8000m)
  • ETA +60 NO ATS delay in addition to what is already being carried

Q

when are 2 DESTINATION ALTERNATES required AND what is the exception to the rule

A
  • relevant weather below landing minima; OR
  • no forecast
    EXCEPTION:
  • if 1 planned alternate has all the requirements as if it were a DEST ALT (+1000’/+500’ and higher of 5000m/+2000m)

Q

what does table 4.11 refer to

A

Minimums for:

  • DESTINATION ALTERNATES
  • ISOLATED DESTINATION AERODROMES
  • ENROUTE ALTERNATES
17
Q

what is the difference between a different and separate runway

A
  • different = different number identifier (runway 03 and 21 are different runways)
  • separate = runways at the same airport whereby if 1 runway were closed, operation to another runway is operationally available (YSSY 34L/ 16L)
18
Q

what are the table 4.11 requirements (DEST ALTN, ISOL DEST AERODROME, ENROUTE ALTN)

A
  • 2 IAP and 2 different suitable runways:
    • ceiling: 2nd lowest MDA + 200’
    • visibility: 2nd lowest MDA + 800M
  • 1 IAP and 1 runway:
    • ceiling: (highest of) 400’ above
      • 2nd lowest MDA
      • circling height
    • visibility: (highest of)
      • 2nd lowest MDA + 1500m
      • circling visibility
  • NO IAP:
    • ceiling: LSALT + 500’
    • visibility: 8000m
19
Q

how much fuel must be carried if 2 DEST ALTN are required

A

highest fuel amount

20
Q

how much fuel need be carried if there is NIL DEST ALTN required

A

15 mins at 1500’ over destination in ISA

21
Q

what is the DEST ALTN fuel required for a ISOLATED DESTINATION AIRPORT

A

2 hours holding at cruise level over ISOLATED DESTINATION AERODROME including FINAL RESERVE

22
Q

what is the purpose of contingency fuel

A

to allow for unforseen circumstances

23
Q

how much is contingency fuel

A

5% of trip fuel but not less than 5mins at 1500’ over DEST in ISA
