APS Groundschool day 1 Flashcards
Checklist handling (3 items)
1 (Red) = Read
2 (Green) = Look
3 (Back) = Listen
remember RLL
Meaning ‘‘TEMPO’’ in metar
Temporary, minimum 30 minutes, maximum 2 hours
Time limit METAR
MAX 60 minuten, normaal gesproken 30 minuten
Meaning ‘‘SPECI’’
Significant weather change, wordt dus eerder uitgegeven dan 30 minuten (wanneer nodig)
Time limit TAF 2 options
TAF short = 9 hours
TAF long = 24 hours
Meaning ‘‘TAF’’
Terminal Aerodrome Forecast, is dus een weersverwachting voor een bepaalde aerodrome
Operating Minima table
DH/DA RVR CAT IIIA --> 50ft 200m CAT II --> 100 ft 300m CAT I --> 200 ft 550m NPA --> DA400 ft 800m
Planning Minimum table
Ceiling RVR/visibility
CAT II/III –> x CAT I (550m)
CAT I –> NPA MDH NPA VIS/RVR
NPA –> NPA MDA + 200ft NPA VIS/RVR + 1000m
Circling –> Circling MDH Circling Visibility
Wanneer takeoff alternate nodig en voorwaarden
Wanneer je niet kunt terugkeren naar je departing aerodrome omdat deze onder de minima ligt.
The takeoff alternate has to be within 1 hour flying with N-1 engines = ongeveer 350 NM
Wanneer destination BELOW minima is OF no weather available
Dan heb je 2 destination alternates nodig die wél boven de minima zijn
Wanneer gebruik je planning en operating minima
during operating phase you always use the operating minima. During the planing phase, you use also the operating minima. Exept with the enroute alternate and destination alternate, there you use the planning minima
MEL meaning + wanneer gebruik je MEL
Minimum Equipment List
Is voor de binnenzijde van het vliegtuig en wordt gebruikt TOT het vliegtuig beweegt op eigen kracht. Gaat daarna over in de QRH
CDL meaning + wanneer gebruik je CDL
Configuration Deviation List
Is voor de buitenzijde van het vliegtuig (bv flaps). De hele reis (voor movement en na movement) blijft het CDL
Verschil QRH en MEL
QRH is probleemoplossend en de MEL geeft extra marge om de operatie voort te zetten
Rectification interval (MEL) 4 categorien
A = no standard interval B = within 3 consecutive days C = within 10 consecutive days D = within 120 consecutive days dat betekent dat binnen 3 dagen de reparatie moet plaatsvinden
Taxi fuel
Fuel consumed before takeoff
Trip fuel
Fuel to reach destination
Contingency fuel
at least 5% of trip fuel
Final reserve fuel
fuel to fly minimum 30 minutes at 1,500 feet AGL
Alternate fuel
fuel to reach destination alternate, via destination
Extra fuel
extra needed fuel by commander
additional fuel
exrta needed fuel by operator
FMC Reserve Fuel
Alternate Fuel + Final Reserve Fuel (weten!)
Voorbeelden Contingency Fuel
Deviations from expected fuel consumption
Deviations from forecast Meteo conditions
Deviations from planned routings and cruising level
An operator must select at least one destination alternate, unless:
- planned flight time takeoff to landing is less than 6 hours
- 2 seperated runways are available at destination
- forecasted visibility is 5000meter or more
- cloudbase is higher than:
- circling height + 500 ft
- 2,000 ft
ETOPS
Extended Twin Operations –> kunnen landen binnen 1 huur ZONDER ETOPS
The fuel remaining on arrival at ‘‘destination’’ aerodrome must not be less than either:
1 Final Reserve + Alternate fuel
2 Final Reservice (if no alternate aerodrome is required –> see requirements)
The commander shall declare an emergency when the calculated usable fuel upon landing at the nearest adequate aerodrome, where a safe landing can be performed, is less than
FINAL RESERVE FUEL
Threat and Error Management TEM (kaas model)
Threat –> Error –> UAS Undesired Aircraft State –> Safe operation OR Accident
The TEM model considers three categories of threats:
1 = Anticipated threats (expected to known) --> thunderstorms, congestion, complex SID, terrain 2 = Unanticipated threats (occur suddenly) --> malfunctions, TCAS RA, ATC ambiguity, unforecasted adverse weather 3 = Latent threats (not directly obvious) --> fatigue, optical illusions, stress or lack of experience
ENVIRONMENTAL THREATS (3 categorien + voorbeelden)
Environmental Threats
Weather –> thunderstorms, turbulence, icing, windshear
ATC –> traffic congestion, TCAS RA, ATC error
Airport –> contaminated/short runway, lack of markings, complex surface navigation
ORGANIZATIONAL THREATS (3 categorien + voorbeelden)
Environmental Threats
Operational Pressure –> Delays, late arrivals, equipment changes
Aircraft –> malfunctions, automation event, MEL/CDL
Cabin –> Flight attendant error, cabin event distraction, interruption, cabin door security
Error is defined as
Actions or inactions by flight crew, that lead to deviation from organizational or flight crew intentions or expectations
TEM model, ERROS (3 categorien + voorbeelden)
Aircraft handling errors –> incorrect altimeter setting, incorrect configuration, speed deviations
Procedural errors –> missed items checklist, incorrect callouts, wrong MEL, wrong weight and balance
Communicational errors –> miscommunication, incorrect phraseology, misinterpretation
A mismanaged error is defined as an error that is linked to or induces an additional error or UAS
thats it
UAS er defined as
3D positie ten gevolg van een error, dus: a position, speed, attitude or configuration of an aircraft that: results from flight crew error, actions, or inaction and clearly reduces safety margins
ASR
Air Safety Report
TEM model, UAS (3 categorien + voorbeelden)
- Aircraft handling –> vertical/lateral/speed deviation, unstable approach, unauthorized airspace
- Ground navigation –> proceeded to wrong taxi/runway, entering wrong taxiway, ramp, gate etc
- Incorrect Aircraft Configurations –> incorrect config of systems, flight controls, automation, engine and mass an balance

Accident
TSAT + window of time
Target Startup Approval Time –> window +/- 5 minutes)
TOBT

Speed mode Pitch mode
During Climb N1 MCP speed
During Descent Retard –> ARM MCP speed
Aborted Engine Start, if one of these occur (4)
- Hung Start
- Wet Start
- Hot Start
- no oil pressure indication by the time that the engine is stable at idle
Hung Start
N1 or N2 does not increase or increase very slowly after the EGT increases
Wet Start
EGT does not increase by 10 seconds after the engine start lever is moved to IDLE
Hot Start
EGT quickly nears to exceeds the start limit
When is engine stabilzed?
