Dispatch & Wx Flashcards
CAT I RVR BELOW 750 m
For RVR values below 750 m to runways without TDZ lights and/or CL lights, a coupled or a flightdirector-flown approach are required.
NPA
Non-precision approach (NPA) procedure
An instrument approach procedure which utilizes lateral guidance but does not utilize vertical guidance. NPAs include Circling, LDA without glideslope, LOC, NDB, RNP - LNAV minima only, VOR.
APV
Approach procedure with vertical guidance
An instrument approach procedure which utilizes lateral and vertical guidance but does not meet the requirements established for
precision approach and landing operations. APVs include LDA
with glideslope, RNP - LNAV/VNAV minima.
Alternate Airport Planning Minima
A destination alternate , a 3% en-route alternate or a take-off alternate
- Pre-flight planning - From one hour before the ETA until one hour after the ETA;
- In-flight planning - At the ETA.
CAT II or III- CAT I RVR
CAT I - NPA RVR/VIS Ceiling shall be at or above DH/MDH
NPA/APV- NPA RVR/VIS + 1,000 m Ceiling shall be at or above DH/MDH + 200 ft
Circling- Circling
Fog
Mist
Haze
MI
FG- Less than 1 km
MI- low lying fog not obstruct horizontal VIS at 2 m
BR-fog>1 km humidity >70%
HZ-fog>1 km humidity
Isolated airport
Removed from ELAL OMA
Terrain Clearance
Deals with Route
EFP - deals with T.O
Windshear
below 1000 feet AGL, in excess of any of the following:
• 15 knots indicated airspeed
• 500 fpm vertical speed
• 5° pitch attitude
• 1 dot displacement from the glideslope
• unusual thrust lever position for a significant period of time.
Ceiling requirements
- Destination Airport(s)-ceiling at or above the MDH/DH for non-precision and circling approaches;
- APM- NPA RVR/VISCeiling shall be at or above DH/MDH
JAA/APPROVED OPERATOR
1.For Tel Aviv and other airports listing more than one set of Air Carrier minima, use the Air Carrier (JAA) minima.
2.The landing minima published on the Jeppesen plates marked JAR-OPS, PANS-OPS, STANDARD
and TERPS are authorized by the CAAI for EL AL use.
3.Some airports prescribe reduced minima for Approved Operators. EL AL is approved
to operate according to the higher of either the “Approved Operator” minima on the airport chart, or the minima in the table above.
EDTO
- Dispatch:special APM. Inflight : Cat I before entering. After entrance- no weather required.
- Special MEL requirements
- Dispatch: fuel for APU. Inflight : start APU before entering
- crossfeed check on ground and last hour of flight.
- supplementary ETOPS (FCOM General)+ OMA
- Alternates 120 min one engine
Critical Fuel
Usually hidden in normal policy, if not - will shown Additional Critical
The aircraft to descent as necessary and proceed to an alternate airport in the event of an engine failure or loss of pressurisation, whichever requires the greater amount
assumption that such a failure occurs at the most critical point along the route; and
• Hold there for 15 minutes at 1,500 ft in Standard Conditions; and
• Make an approach and landing.
Contingency Fuel
which shall be the higher of a or b below:
a. An amount of fuel to fly for 5 minutes at holding speed at 1,500 ft above the destination
b. The lowest of:
i. 3% of the planned trip fuel provided:
The 3% ERA within a circle with radius 20% of total flight distance, the centre of which lies at a distance from the destination of 25% of the total flight plan distance,
or at 20% of the total distance plus 50 NM, whichever is greater ;
ii. 5% of the planned trip fuel, based on the consumption rate used to plan the trip fuel;
iii. 20 minutes flight time based on the consumption rate used to plan the trip fuel
Jet Stream
Symbol II
used whenever theheight of the jet axis changes by +/-3000ft or the speed changes by +/-20kt.
CB
ISOL = individual CBs (isolated); OCNL = well separated CBs (occasional); FRQ = CBs with little or no separation (frequent); EMBD = CBs embedded in layers of other clouds or concealed by haze (embedded).
