Planning And Briefing Flashcards
What information is required before each flight?
Commander must have AIS and MET for flight
AIS information must include details of all ATC procedures and restrictions, navigation and communications facilities and restrictions, aerodromes and ground aids. He/she must be satisfied that ground facilities and services are available and adequate
LORETTO brief meets this requirement.
Is take-off Alternate required?
OM A 8.2.5.f
Needed if can’t return for MET or performance reasons.
Normal operating minimum apply.
Engine failure limitations must be considered.
WX - time of departure for Alternate +/- 1 hr - see OM A 8.2.5.m
Take off Alternate required if runway is contaminated
Location of take-off Alternate?
For two-engined aeroplanes: within 60 minutes flying time in still air standard conditions at the one-engine-inoperative cruising speed based on the actual takeoff mass.
S/E 60mins - 400nm
Location of Alternate for ETOPS aircraft?
For ETOPs aeroplanes within 120 minutes flying time in still air standard conditions, or the approved ETOPS diversion time if this is less, at the one-engine-inoperative cruising speed based on the actual takeoff mass.
ETOPS - 120mins - 800nm
If take-off Alternate nominated is within the USA
At the time of departure, the weather at the take-off alternate (if required) shall not be below the alternate weather minima specified for that aerodrome
600 ft/2 sm (precision approach)
800 ft/2 sm (non-precision approach)
OM A 8.2.6.d
Is a destination Alternate required?
BA Policy to always have one. However zero required if less than 6hrs At +/- 1hrs ceiling 2000ft or circling +500ft VIS greater than 5km Or Isolated destination
When are two destination alternates required?
If destination weather at 1hr before estimated arrival time to 1hr after is below minima or no met information available.
What diversion fuel is loaded if dispatched without destination Alternate.
If a flight is dispatched without a Destination Alternate, Diversion Fuel must be replaced with enough fuel to allow holding for 15 minutes at 1,500 ft above the destination aerodrome in standard conditions. - equates to half Final Reserve fuel.
What are the two types of destination alternates?
The two types of destination alternate: Fuel Alternates and Commercial Alternates.
What is the Fuel Alternate?
Used if diversion considered unlikely.
There is a possibility that there could be a lack of ground handling facilities.
What is the commercial Alternate?
Used if diversion considered likely.
Takes into account such factors as ability to handle and disperse passengers and the availability of BA staff or representatives. The commercial preference of the selected alternates for each destination are identified on the Cirrus flight plan using a C and the preference number, e.g. C1.
If LVO’s expected - COMMERCIAL ALTERNATE USED OM B 1.1.1.b
Is an en-route Alternate required?
Used to reduce contingency fuel.
Contingency fuel - 5% of the TRIP FUEL required from departure to destination; or If an En-route alternate is available and selected, not less than 3% of the TRIP FUEL
Does the weather at the destination and any alternates meet planning minima?
If destination is below planning minima it is possible to depart but extra destination Alternate is required.
What is the time window for Alternate weather planning minima?
At the planning stage, commencing 1 hour before and ending 1 hour after the estimated time of arrival at the aerodrome, the weather conditions will be at or above the applicable planning minima.
What is the time window for ETOPS Alternate weather planning minima?
For ETOPS en-route alternates the time window for assessing suitability of weather conditions commences at the earliest potential time of landing and ends one hour after the latest nominated time of use of that aerodrome
