Planning Flashcards
En-route alternate requirements
Within one hour engine out cruise, ISA, still air.
380 nm 319
400 nm 320
Weather forecast application
Generally mean wind should be within limits, gust can be disregarded. Both can be disregarded in tempo transient conditions of deterioration (also prob tempo conditions). Tempo improvements should be disregarded.
Take off alternate requirements
Required when conditions preclude a return to departure aerodrome. Must be within one hours still air flight time at one engine out cruising speed (ISA conditions, actual t/o weight). OMB states max 320 nm both 319/320.
Above max landing 320 always requires take off alternate because no automatic landing approved above that weight. 319 can return up to 69T (FCOM limitations).
Required equipment for RNAV(GNSS)
FCOM PRO SPO 51
One FMS One GPS One MCDU One FD One PFD + ND (PF side) Two FCU channels
Required for RVSM airspace?
Two ADR's i.e. 2 primary altimeters One transponder AP FCU altitude selection One FWC for alt alert
Check PFD altitude indications.
OMA 8.3
OMB supp techniques, FCOM PRO SPO
Minimum requirements for visual approach
2500ft cloud base
5000m visibility
What is the planning minima required for a destination alternate with only non-precision approach available?
Non-precision minima +200ft/+1000m
How long is a TEMPO forecast expected to last?
Should not last more than one hour in each instance and cover less than half the period.
What are the limitations of LMC’s?
New load sheet if plus 10/minus 20 pax
If LMC positive but less than 250kg minus 1 from flex.
T/O PERF must be re-done if:
LMC >250kg
CofG more than 2% change
LMC
What is a MORA?
Minimum off route altitude.
A route MORA provides clearance within 10nm of route centreline and end fixes.
A grid MORA provides clearance within section outlined by longitude and latitude.
MORA values clear all references points at or below 5000ft amsl by 1000ft and all those above 5000ft amsl by 2000ft.
Careful using route MORA’s from the OFP as they’re only valid within 10nm of the planned route centreline.
What is a MEA?
Minimum en-route altitude.
Lowest published altitude/level that meets obstacle clearance requirements between two radio fixes.
What is a MOCA?
Minimum obstruction clearance altitude.
Like MEA, meets obstacle clearance requirements for off airways segments and VOR airways.
What is MSA?
Minimum safe altitude.
Provides 1000ft clearance within 25nm of navigation facility stated. Until on final descent(?)
