OMA / OMB Flashcards
When do we not need a destination alternate
o Flight < 6 hours
o Vis 5 km +
o Ceiling 2,000 feet or Circling + 500 feet if greater.
o Two Separate Runways
When can we consider runways to be separated?
o Separate Approach Procedures based on Separate Approach Aids
o If they cross a blockage on one does not prevent the planned operation on the other.
When do we require two destination alternates?
o If destination weather is unavailable.
o If destination weather is below planning minima for ETA ±1 hour
o Landing not assured at destination as Landing depends on Specific Wind Component / runway state.
When planning for an alternate, the TAF indicates in a prob/tempo that the weather will be below limits.
Can this alternate be used?
SAM EDIT: I’M NOT SURE THIS IS SO SIMPLE.
OMA TABLE 8.1.6.1 shows the applicability criteria.
For me it means:
Tempo / Prob which shows improvement AT DEST ALT should be disregard
If deterioration and transient / showery / short-lived then mean wind and dust exceeding limits may be disregard
If it is a persistent (haze, mist, fog) then mean wind should be within required limits.
. o Yes
o Prob/tempo can be disregarded
What is the planning minima for a Take-off alternate?
o At or above the minima for the expected instrument approach.
o Any limitation related to one engine inop or dispatch under MEL shall be taken into consideration.

RED - Specific & credible – Requires immediate action ie diversion/disembarkation.
AMBER (Ground Only) doubtful credibility - Discuss with Network Duty Manager course of action.
GREEN - Not specific, not credible – No action required.
You receive a RED bomb warning. What would you do?
On Stand
o Disembark Pax & Crew
o Hand Baggage to be taken off with them.
o Give a ‘Security Problem’ as the reason.
o Pax to be taken to location separate from other passengers
o Advise ground crews to vacate the area
o Remove aircraft to a remote location & search if time exists.
o After Police give “All Clear”
Full search of aircraft including catering, etc.
All Passengers, cabin & hold baggage to be screened again
Pax to be reconciled with their luggage
All of this before re-embarkation is permitted.
You receive a RED bomb warning. What would you do?
During taxi
o Advise ATC & passengers of a “Security Problem.”
o Request details of remote parking requirements
o Request immediate availability of steps to the aircraft
o Advise ATC of a need to locate passengers 200 m upwind of the aircraft as quickly as possible.
o Disembark Pax & Crew
o Hand Baggage to be taken with them
o Only use slides if steps are not available (normal evac procedures now apply)
You receive a RED bomb warning. What would you do?
In Flight
o Declare an emergency
o Divert to nearest suitable airfield
o Fly as normally as possible, in accordance with checklist, etc. (turbulence penetration speed good compromise)
o Brief Cabin Crew to conduct a discrete search of toilets & galleys for suspicious articles.
o Do not raise cabin altitude, maintain or reduce if possible, Level off & descend to FL100 when possible.
o PA: Should state that threat is against the airline & although most likely a hoax, must be treated seriously.
o On landing same as for threat on taxi.
What is the difference between a precautionary and emergency landing?
A precautionary landing is one in which under normal circumstances there will be no requirement to evacuate.
What calls would you make for an unplanned and planned emergency landing?
Unplanned: “ATTENTION CREW, BRACE BRACE.”
Planned: 2,000 feet “CABIN CREW TAKE UP LANDING POSITIONS.”
500 feet “BRACE, BRACE.”
