Shortly after takeoff, a swept wing aircraft encounters a downdraft. Best recovery technique would be to?

Raise aircraft alpha to just less than the stick shaker speed

Highest temp in a gas turbine engine is?

In the primary part of the combustion chamber

The HOT battery bus is powered?

Only by the aircraft battery

Which is NOT an element of anti-skid

Pneumatic reserve braking

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

Which one is NOT an Air Data computer output?

Pitch attitude

The nose wheel steering follow up linkage does what?

commands the steering valve to select the nose wheel in neutral during gear retraction

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

Throttle is set during a climb in a turboprop aircraft. Which element is maintained as the aircraft climbs?

EGT

Vortex generators on a horizontal stabiliser primarily do what?

Reduce turbulent flow separation, and preserve the elevator authority at all flight speeds

Which answer best describes the effect of dissolved water in Avtur fuel?

Reduced specific gravity, causes microbial infestation and sludge

Tires must be replaced when?

There is a bulge in the tread

Air conditioner load on an engine can be relieved by?

Selecting "recycle" mode on the air conditioner controller

Body gear?

Turns in the opposite direction to the nose gear to reduce tyre scuffing

Spiral instability is worst when?

Directional stability is strong compared to lateral stability

Climbing at a constant CAS, you would expect Mach number and TAS to?

Both to increase

Climbing at a constant speed just below Vmo, you would expect?

The Mmo value to eventually be exceeded

To reduce the Vmcg speed you could?

Decrease the takeoff thrust setting, and/or move the CoG forward

A high density altitude affects the Vmcg speed in what way?

Decreases it

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

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

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

Which statement is most correct about drag?

Induced drag is highest at the angle of attack of maximum lift

Compared to a conventional wing a laminar flow wing has its position of max camber ?

Further rearward

In comparing Mcrit and Mcdr of a supercritical wing to a conventional cambered wing?

Mcrit and Mcdr are both higher

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

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

Leading edge devices?

Contribute most to lift values at high angles of attack

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

Which statement best describes properties of Zap flaps?

Increases camber, drag and wing area. Deployment requires nose up trim changes

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

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

Which statement best represents the order of events as speed increases

Mcrit, Mcdr, Mfs speed of sound, Mdet

Which answer best describes the airflow qualities behind a normal shockwave?

Temp and pressure rise, velocity and Mach number decrease, density increase

Airflow direction

through an oblique shockwave changes direction but does not through a normal shockwave

For high flying jet aircraft featuring swept wings

Low speed stall indicated airspeed increases cumulatively as altitude is gained

Aerodynamic ceiling for a given aircraft is?

Lower with increase turbulence/greater bank angle

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

To ensure correct flow direction is maintained in a hydraulic system you would use?

Check valve

Which answer is most correct?

Pneumatic system is lighter than an equivalent hydraulic system

Shuttle valves move?

Automatically should normal system pressure fail

Which is incorrect ?

Most air transport jet aircraft use electrical starter mechanisms

Ideal humidity for an aircraft cabin is?

60%

Humidity level possible in a high flying aircraft cabin is about?

30%

Ideal temperature range for humans is?

18 - 24 degrees

Which statement is most correct?

Bleed air extraction during takeoff reduces takeoff and climb performance

Which statement is NOT correct

Pre cooler cold air is supplied from the expansion turbine. This is called bootstrapping

To achieve a "fail operational" autopilot coupled ILS approach?

Three autopilots engage at 1500ft RA

Spoiler panels are?

Located just ahead of the trailing edge flaps, deflecting the roll spoilers up on the right wing will see the right wing aileron deflect upward to initiate a roll to the right
