Pre-flight Planning Flashcards
What is a ETOPS en-route alternate
Adequate aerodrome which has at least one instrument approach procedure
Where must the take off alternate be located
For 2 engine aircraft l:
1 hour flight n-1 in still air
Or etops = max 2 hours
For 3/4 engine;
2 hours flight N-1 still air
When does a operator not need to select a destination alternate
Duration of flight does not exceed 6 hours
AND
2 runways available and forecast +/-1hr from eta = ceiling @least 2000ft or circling height +500ft
Vis 5km
Or isolated and no adequate alternate exists
When must a operator select 2 destination alternates
Forecast = weather below minima
No met info available
When must a fuel check be carried out
At least one each hour
What factors affect aircraft performance
Mass Temp Pressure alt Field length Slope Wind Configuration
Not humidity or surface factor
What do pax need to be shown before take off
Use of seat belts
Location / use of oxygen
Location / use of life jackets
What do pax need to be reminded of after take off
Smoking regulations
Use of seat belts during turbulence
What fuel can you not refuel with while pax are on board
Avgas
Jet B
What needs to happen when refuelling with pax on board
One pilot on board whilst refuelling Seat belts off No smoking lights on Cabin crew prepared to evacuate 2 way comms with re fueller Fire services on call
What RVR can you take off in without authority approval
150m (cat A/B/C)
200m (cat D)
When can RVR minima for take off be reduced to 125m (150m cat D)
Low vis procedures in force
High intensity centre lighting at 15m spacing (HICL)
High intensity runway lights at 60m spacing (HIRL)
Crew are LVTO qualifies
When is noise abatement procedure not advisable
Runway surface contaminated
Crosswind component 15kt (inc gust)
Tailwind (inc gust) 5kt
Windshear / TS
Non etops how far from a adequate diversion can you be
60mins
How are minimum time routes calculated
In seconds by computer software called
Neighbouring optimal wind routing (NOWR)
