Emirates Flashcards
Same engine, what happens to N1 and Thrust if you move to hot and high airfield
N1 increases and thrust decreases
Ac fitted with TCAS legality?
MTOM >5700kg or >19 px
Fire extinguisher for Elec fire
CO2
ROD varies with weight at constant high speed
Lighter = faster ROD
1 QNH = xft
1m = x feet
27 ft
3.3 ft
What determines opt cruise level
Weight, wind, CI, Temp, Fuel
If you have out- and in-board ailerons, why to out-board ones only work in slow flight
They will twist wing-tips at high speed
Ice accrues on top and bottom of wing. What happens to stall speed and maneuverability?
Stall speed increases
Man decreases
Final Res.
30 mins holding @ 1500’ @ holding speed @ alternate
What do we expect with convective clouds in layer of stratus?
Embedded TS
Clouds indicating severe turb?
Lenticular
Relationship between V1 and Vmcg
Vmcg </= V1
Vmcg is minimum speed during takeoff run at which, if the critical engine suddenly fails, it is possible to maintain directional control using only aerodynamic controls
West = Even
East = Odd
RVSM levels?
Even Odd
RVSM 270-410
What happens to V1 if anti-skid becomes inop
decreases
ISA temps?
0’ = 15 deg
2 deg per 1000’
Anabatic wind?
Kadabatic
A: Blows up a steep mountain slope due to heating of the slope
K: Blows down slope (high density air drifting down due gravity)
What forms a CB
Lots of moisture
Mass of warm stable air
Source of energy to lift the warm air up quickly
ASDA, TORA, TODA, TODA?
Balanced field?
TODR = ASD
It takes same dist to stop from V1 as it does to lift off
ASDA = TORA + what?
Stopway
Stopway definition
Unprepared surface which can support weight of AC but isn’t part of the TORA (is part of the ASDA)
Clearway with increase/decrease MTOW and increase/decrease V1
Increase MOTW
Decrease V1
Aerodynamic benefits of swept wing?
Negatives?
Benefits: High Mach cruise speeds, stability in turbulence, low drag
Negatives: Poor lift, higher stall speeds, greater potential for wing-tip stalling
VASI
Like PAPI but only 2 lights
What happens to specific fuel consumption with altitude
decreases
Bleed air for AC and anti-ice on take of perf?
Decreases perf
2 AC approaching head on for crash, which way do we turn
Right
Maintaining constant alt, effect of slats and flaps on AOA?
Slats - Decrease AOA
Flaps - Increase AOA
Static port clogged on descent - will altimeter over or under-read?
Over
In N Hemisphere, what happens to wind s alt increases
Veers - anti-clockwise - and speeds up
Low pressure area weather?
Wind and rain
Winglets effects?
Reduces induced drag
MSA on charts within xNM?
25
Sea breeze
Cool breeze from sea to land
Jet A1 fuel freeze temp
-47 deg C
Airspeed in descent with static blocked?
Overread
Airspeed in climb with bloced pitot
Increase
Wx associated with Inter Tropical Convergence Zone
Convective clouds and heavy precipitation
Belt of low pressure air near equator where N and S winds meet
Max time for Jet engine to spool from idle to full thrust?
8 secs
Effect of slats on max AOA
Increase
Fog in Dubai during which months?
March-May - worst in March
Monsoon season in South Asia?
Summer
What happens to stall speed in turn?
Increases
Increase of weight on stall speed
Increases
COntaminated RW
25% covered in 3mm
Better for stopping on dry RW - brakes or reverse thrust
Reverse thrust
What is dutch roll
Rolling and yawing in different directions at the same time - common in swept wing
Lat/long of Dubai?
25.18N 55.20 E
CofG moves aft
Reduces drag and increases range
decrease longitudinal stability
RW edge lights turn to amber, how long left
600m
RW centrline lights alternate red and white, then red only - how long left
900m and 300m
Taxiway lights>
Out - blue
Center - green
Take off segments
1: 35’ to gear retracted
2: Gear retraction until acceleration height (min 400’)
3: Acceleration height to flaps retracted
4: clean to 1500’
ETOPS?
Extended twin operations
Can operate more than 60 mins away from an airfield if an engine fails
