28
Critical engine
Our engines are counter rotating.
Most critically affected engine failure if we rejected the take off depends on wind.
Cross wind affects the control due to tendency for aircraft to turn
into wind as result of rudder deflection.
# # note
Generally the left engine is considered the critical engine. When there is a strong left x wind a left EF situation can be dangerous if not properly handled.

34
What is cost index?
A cost index (Cl) is a performance management function which optimises the aircraft's speed for the minimum cost.
A low cost index reflects high fuel costs (as in fuel is $$ per dollar) and results in a lower cruise speed.
Ranges: 1-200
LRC = 25 (Approx)
CI 0 = Maximum Range
| The CI is the ratio of the time-related cost of an airplane operation an
## Footnote
CI take into account specific route factors such as the price of fuel at the departure and destination airports so that the aircraft is flown at the correct speed to balance the fuel costs against the dry operating costs. An incorrect CI will always cost more money.

Known as an aircraft’s absolute ceiling
58
Take me through a rejected take off as if I was a new pilot on type?
Two types of RTO’s:
1. Low-Speed RTO
Prior to the 80-knot call, it is envisaged that the take-off will normally be rejected for any significant malfunction or abnormal situation. Speed will l usually be well below the applicable VMCG (the speed at which insufficient rudder authority is available) and so it is important for a pilot carrying out any low speed rejected take-off to be ready to make any necessary control inputs to the nose gear steering system via the tiller.
2. High Speed RTO (AFTER 80kts)
Whilst a successful rejection of take-off from V1 is achievable in all but exceptional and very specific cases, it is universally recognised that the closer the speed gets to V1 the greater the risk involved in a decision to stop.
Once at high speed, it is usually specified that the take-off will only be rejected for major malfunctions such as an engine failure, fire or at the discretion of the pilot in command in the event that a similarly serious situation is perceived.
## Footnote
Rejected Take-offs and Runway Excursions
The **main** reasons why runway excursions occur during rejected take-offs can be categorised as:
1. The decision to reject the take-off is made after V1 and there is insufficient runway length left to come to a stop on it.
2. The flight crew actions required to achieve a rejected take-off are not carried out in a sufficiently prompt and/or comprehensive manner.
3. Stopping devices are not used to their full capacity.
4. It is found at VR that it is impossible to achieve rotation (performance)
59
What is the purpose of swept wing?
Increase Mach number capability. Enables the outside of the wing to stall before the inside of the wing.
## Footnote
… increasing the aircrafts critical mach number.
Other benefits include reduces form drag due to their slender profile, and less suspect to turbulence due to their poor lift qualities.
60
What is the purpose of winglets?
Reduces induced drag by dispensing span-wise airflow, preventing the intermixing of these airflows that otherwise would create induced-drag vortices
## Footnote
Fun fact, winglets actually increases parasite drag.
61

66
Balanced field
When ASDR = TODR
**REQUIRED**
The balanced field length is the shortest field when a balanced field takeoff can be performed.
67
What does wet runway do to V1, why is screen height different.
Wet runway decreased V1. Due to longer distance required to stop. Screen height is reduced to 15 feet. This is due to a **portion of the airborne distance being added to the ground run**, as a result of the increased ground run used between the wet V1 and VR if an engine failure occurs at the worst point, i.e., just after the wet V1 and prior to VR
68
What is a SPECI?

76
What is aquaplanning and at what speed will the aircraft aquaplane?
9 X square root of the tire pressure in psi for takeoff
or
7.6 X square root of the tire pressure in
psi for landing
## Footnote
Aquaplaning is the phenomenon of a tire skating (not rotating) over
the runway surface on a thin film water. It is caused by the buildup of
a layer of water beneath the tire, which becomes a wedge between the
tire and the runway. This wedge of water effectively lifts the tire off
the ground, reducing the friction forces to practically zero. Therefore,
wheel braking has no effect, and directional control also may be lost.
Aquaplaning is extremely significant on jet transport aircraft and can
increase the stopping distance required significantly.
77

You’re actually lower than it indicates
122
After an aircraft has passed through a volcanic cloud which has blocked the total pressure probe inlet of the **airspeed indicator** the pilot begins a stabilized descent and finds that the indicated airspeed does what?
Decreases steadily
(Under read in descent)
123
Aircraft depressurised, what is the estimated time of useful consciousness at FL400?
15 seconds
124
What is a typical fuel flow in cruise for the B737?
2500kg/hr
Rule of thumb:
(IAS x 10/2)-200 = FF per engine
125
What are your aircrafts cruise power/thrust settings?
Rule of thumb (Cruise speed):
N1 = (2 x Alt/1000) +10,
eg at
FL350 = 70+10 = 80% N1
126
What is the lowest and highest Altitude/Flight Level for RVMS in Australia Airspace?
FL290 to FL410
127
What is the vertical separation in RVMS airspace between aircraft on opposite tracks?
1000’
128
When would the PIC declare to ATC “Minimum Fuel”?
when the pilot calculates that any change to the existing clearance will result in landing with less than the FIXED FUEL RESERVE
129
For a Runway to be declared Contaminated by Standing Water, what is the minimum depth required?
3mm
130
What actions should be taken in RVMS airspace if the SSR transponder fails?
Notify ATC “Negative RVSM”
131
How does **Advection fog** form?
When a moist air **FLOWS** from a relatively WARM sea to a cold land mass which cools the air.
## Footnote
Fog forms in the same way as cloud, when moist air is cooled beyond its saturation point and condensation occurs, OR EXTRA moisture is added to make the air saturated.
132
What is V2?
V2 = take off safety speed, must be obtained by 35 ft.
Offers safe margin above stalling speed and in the event of an engine failure, ensure controllability!
133
What is Va?
Va (manoeuvrability speed)
speed at which full aerodynamic control movements will **not** overstress the aircraft
134
Where does the missed approach start and end?
The point specified on the AIP chart where the missed approach begins (MAPt), and a point or an altitude/ height where it ends.
135
Where is the missed approach point for a 3D approach?
The point of intersection of a glide path with the applicable DA/H in precision approaches;
136
How is the tropopause indicated on SIGwx charts?
Suare box with the altitude inside.
