Pneumatic reserve braking
5
Compared to a turbojet of the same thrust output, the high pressure turbine of a turbofan would be?
Larger due to the reduced mass airflow
6
Which one is NOT an Air Data computer output?
Pitch attitude
7
The nose wheel steering follow up linkage does what?
commands the steering valve to select the nose wheel in neutral during gear retraction
8
With respect to a shockwave on a conventional wing section, which answer best describes the characteristics of what airflow ahead and behind the normal shockwave?
Super ahead of the shockwave, sub sonic behind with no change in direction
9
Throttle is set during a climb in a turboprop aircraft. Which element is maintained as the aircraft climbs?
EGT
10
Vortex generators on a horizontal stabiliser primarily do what?
Reduce turbulent flow separation, and preserve the elevator authority at all flight speeds
11
Which answer best describes the effect of dissolved water in Avtur fuel?
Reduced specific gravity, causes microbial infestation and sludge
12
Tires must be replaced when?
There is a bulge in the tread
13
Air conditioner load on an engine can be relieved by?
Selecting "recycle" mode on the air conditioner controller
14
Body gear?
Turns in the opposite direction to the nose gear to reduce tyre scuffing
15
Spiral instability is worst when?
Directional stability is strong compared to lateral stability
16
Climbing at a constant CAS, you would expect Mach number and TAS to?
Both to increase
17
Climbing at a constant speed just below Vmo, you would expect?
The Mmo value to eventually be exceeded
18
To reduce the Vmcg speed you could?
Decrease the takeoff thrust setting, and/or move the CoG forward
19
A high density altitude affects the Vmcg speed in what way?
Decreases it
20
With the loss of the right engine, which statement is most correct?
With a bank toward the live engine, less rudder deflection will be needed, and the skid balls will be slightly displaced to the live engine side
21
In an aircraft with two engine mounted pods beneath the wing, and one tail mounted engine with its thrust line up high (e.g DC10), failure of the left wing mounted engine would result in?
A requirement for pitch up trim, a yaw to the left, right rudder trim required
22
Regarding factors affecting Vmca, which statement is most correct?
High density altitude, dihedral and skid induced blanketing of the live engine wing, reduce Vmca values
23
Which statement is most correct about drag?
Induced drag is highest at the angle of attack of maximum lift
24
Compared to a conventional wing a laminar flow wing has its position of max camber ?
Further rearward
25
In comparing Mcrit and Mcdr of a supercritical wing to a conventional cambered wing?
Mcrit and Mcdr are both higher
26
Which statement is MOST correct?
Shark teeth or stall strips are fitted to the leading edges near the wing roots to allow the wing roots to stall first, and provide more stable static longitudinal stability at the stall
27
Which statement best describes the properties of slots and LE flaps?
Slots and slats re energise the boundary layer, slats and LE flaps increase the camber
28
Leading edge devices?
Contribute most to lift values at high angles of attack
29
The leading edge devices fail to extend on approach, but trailing edges do extend normally.You would expect what changes to approach angle, drag, selected approach speed and cockpit cut off angle, compared to an approach with all high lift devices deployed?
Lower alpha and drag, higher approach speeds, improved view over the nose
30
Which statement best describes properties of Zap flaps?
Increases camber, drag and wing area. Deployment requires nose up trim changes
31
Shockwaves form?
First over the upper wing surace where airflow reduces to below Mach 1. The lower the shockwave forms later, but reaches the trailing edge before the upper shock
32
which statement is most correct as speed increases beyond Mcrit ?
The centre of lift moves aft, lift reduces, and a nose down pitch moment occurs
33
Which statement best represents the order of events as speed increases
Mcrit, Mcdr, Mfs speed of sound, Mdet
34
Which answer best describes the airflow qualities behind a normal shockwave?
Temp and pressure rise, velocity and Mach number decrease, density increase
35
Airflow direction
through an oblique shockwave changes direction but does not through a normal shockwave
36
For high flying jet aircraft featuring swept wings
Low speed stall indicated airspeed increases cumulatively as altitude is gained
37
Aerodynamic ceiling for a given aircraft is?
Lower with increase turbulence/greater bank angle
38
Increased apparent gross weight does what if anything to the speed margin between initial buffet speeds?
Reduces it

An aircraft is cruising at a very high altitude and experiences buffet. This is?
high or low speed buffet
