Fom Flashcards
Fom
By what distance to you have to avoid thunderstorms?
-Avoid amber areas when possible.
-When below freezing level by at least 10NM.
-When above freezing level by at least 20NM.
How high above a thunderstorm do you have to be to overfly it?
-At least 5000ft above
-At least 10 000ft above if winds are greater than 100kts.
What is the formula to determine relative height of thunderstorm using radar?
distance (NM) x tilt (in °) x 100
ie; return showing 40nm and disappears at 3° down
40x3x100. a/c is 12000ft above.
When should you avoid T/O with regards to LLWS?
-Should avoid when 15kts or greater loss of airspeed reported.
LLWS caution
Use caution for LLWS when front with greater than 6°C temp difference, or
front moving at greater than 30kts.
Fuel considerations for low temp cruise…
-When SAT -65°C or less monitor fuel temps.
-Dispatch should not plan flight at temps lower than -65°C for more than 90 min, or
-they should use Boeing fuel temp program.
LAHSO (land and hold short operations)
NO LONGER AUTHORIZED DUE TO SALGA!
NOT AUTHORIZED in USA
Only allowed in Canada.
-Cannot accept LAHSO clearance if below 1000ft AGL.
-Must calc landing distance required and it has to be 1000ft less than available.
-Must stop 200ft before intersection.
-No more than 3kts tailwind.
-No CB or LLWS.
-Wx better than 1000/3.
-Rwy must be dry.
How long do you have to file an ASR
An ASR must be filed within 24hrs. Reportable incidents found FOM 2.5.1 and 12.2.2
T/O restrictions with regards to icing.
T/O not authorized during,
-HAIL
-HEAVY ICE PELLETS
-MODERATE OR HEAVY FREEZING RAIN.
Landing restrictions with regards to icing.
Landing not authorized during,
-MODERATE OR HEAVY FREEZING RAIN
Operational control (of flight and flight plan)
-Once PIC accepts flt plan co authority for flt watch commences.
-Once T/O thrust is applied PIC has final decision on any changes to OFP (should advise dispatch of any flt plan change or major change in conditions)
Disagreement resolution with Flt Dispatch
Most conservative course of action.
PIC shall take conservative course of action and their decision is final.
OFP package revision (delayed flights)
If there is a delay of 2 hrs or more Flt Dispatch will review OFP and revise or refile is required.
319/321 fuel burn values
A319/320 taxi 9kg/min (1 eng) 15kg/min, flight 50kg/min
A321 taxi 9kg/min (1 eng) 15kg/min, flight 60kg/min
Determining cont fuel.
-5 min fuel burn at est landing weight,1500ASL, ISA conditions, or
-difference in flt planned burn and actual burn for last 2 years on same city pair.
Protected fuel definition
Fuel planned to be available over a specific point. (destination, alternate…)
fuel burned to carry the extra fuel will be accounted for in “burn”
What fuel is protected?
ALTN
CONT 5 MIN
ETOPS
SUPP (top up to ensure a specific amount of fuel over destination)
RESERVE
NAIFR SAP (second approach)
Which fuels does “min T/O fuel” include?
Burn
Reserve
MEL
Cont 5
NAIFR SAP
Altn
ETOPS
Does “min T/O” fuel include for terminal/enroute weather delays?
No
Minimum Fuel advisory
Occurs when crew is committed to land at a specific aerodrome (NAIFR, dropped alternate).
-Advise ATC asap and then at each comm transfer.
-It is not an emergency but advises an emergency situation may occur.
-No ATC priority (possible special handling)
-Must declare an emergency and advise why (low fuel and fuel in minutes remaining) if fuel situation warrants.
Fuel Emergency (Mayday, Mayday, Mayday)
Crews shall declare an emergency when they become aware that under existing or expected conditions flight will land with less than reserve fuel. They shall provide a conservative estimate in minutes of fuel remaining.
Fuel Spills
Crews shall,
-cease fuelling immediately
-advise dispatch and cabin crew
-deplane pax if major fuel spill occurs ( greater than 1.5m in any direction or exceeding 12mm in depth)
-Ensure pax are kept well clear of the area
-A320- Normal APU shutdown must be completed
Low and Over for visual aircraft inspection
-Not recommended for inspection of landing gear.
-Prohibited for routine troubleshooting with passengers on board.
Landing with Damaged or Retracted landing gear
-When possible proceed to airport with adequate ARFF.
-Use longest rwy into wind, preferably ashpalt vs concrete.
-Use inactive rwy if possible.
-ACR policy is that rwy not be foamed and land on rwy vs turf.
