agk/pof oct exam

[FRIDAY]

Some questions I remembered but was unsure of, whats your answers?

AGK
1 At "break release" the position of the propeller and the propreller lever are?

Lever aft / prop coarse
Lever fwd / prop fine
Lever fwd / prop coarse
lever aft / prop fine


2 The thermal switch is what type of switch?

The answer I picked was quick tripping but I believe thats for a magnetic switch???

3, 2ptQ, Theorectically what is said about an engine in cruise with hottest egt? Not sure about wording.

15:1
1:8
Cruise pwr
XXXXXXXX

4, 2ptQ, In relation to the carbourettor what are you actually adjusting??

Air
Fuel
Air/fuel
mixture


POF
1. what happens 1st, was the basics of this q, does the stick pusher occur before or after the stick shaker.

2 Minimum angle of attack, what type of stall it occurs?

Shock
accelerated
Deep
XXXX

3 The numerical q, with tas 150kts, aob 45

9000
2334 i went for
10099
xxxx

I have alot more and will post them shortly, unfortunately the wording is not exact but any opininions on ans is much appreciate

1. Lever Forward/Prop Fine
is the answer I went for. For the prop, fine is a lower angle than coarse.
2. Thermal Switch:
The answer i went for was the was the one that prevents an overtemperature.
3. I am pretty sure the answer was 1/15th. I saw that one in feedback.
4. I am pretty sure it was just the amount of fuel, and nothing else.
AGK

Thanks for reminding me what the 2 2 pointers were, I forgot. I hope that the above answers are correct,

One question I had about the AGK exam regarded the APU.. something along the lines of what can it replace on the ground.
The options were:
The A/C, the generators.
Just the generators.
and i do not remember the rest.. anyone know what the answer was here?

AGK

1. Lever forward/fine pitch
2. The switch is temperature dependent. It pops if T > threshold.
3. The air/fuel mixture is optimum (chemically correct) 15:1
4. The carburator has two adjustments :
- Mixture needle (controls air/fuel ratio)
- Throttle valve (controls the amount of mixture into cylinders)

POF

1. Stick shaker and then stick pusher
2. shock stall
3. I don't understand the question ...

[bad credit]

The formula for the third question which was the 2 marker question in P of F is

Vsquared / g tan bank angle

I hope that makes sense in this format. The answer you went for is the correct one....... with this formula.
The speed was 300kts in the question and to use this formula you have to work out the v speed (300kts) in metres per second squared, then divide by 10 tan 45 which would give the answer about 5m out.

Here are the questions I can remember from Octobers PoF with any answers that I can recall or just those that I put.

If it seems a bit disjointed it is because it is copied from an e-mail conversation with my ground school instructor.

An aircraft in straight & level flight is subject to a vertical gust. Which part of the airframe (may have said wings - not sure) will the immediate change of lift act through?
Answers were: CG, AC, Centre of thrust & neutral point.

Which of the following statements regarding vmcl are correct?
i) Is affected by engine failure on take off
ii) Is always affected by maximum rudder deflection

Answers were: a) i) is correct (ii) is incorrect
b) etc, etc

Va as an IAS is: (definately said IAS)
Answers were a combination of 'In/dependant of weight' & 'In/dependant of altitude

The stalling IAS in the climb will:
Answers included: a) remain constant
b) Constant but increases with altitude due to compressibility

The 300kts / 45 degree angle of bank question - what is the radius of turn. 2 marks


2 Aircraft of the same weight and the same AoB. Aircraft 'A' is at 150 kts and 'B' is at 200 kts. Which has the highest rate of turn?
(This was a variation on the usual question where the weight is the different but speeds are the same)


An aircraft with pod mounted engines (I think it said pod - not sure, but the way it read was that the a/c would pitch up with a power increase) increases power. What elevator deflection is required to maintain zero pitch.

A symetrical aerofoil going from subsonic to supersonic, what happens to the AC?
Answers were a mix of fore and aft movement about the 25 - 50%MAC


Staightening up from a turn, correct response is provided by?
Answer I chose was differential aileron

The pilot of a twin jet wishing to maintain alt in a level turn must?
Answers included and were a mix of: de/Increase AoA and de/increase thrust

What factor will decrease ground distance covered in a power off glide
Usual options of headwind, tailwind, inc weight & decrease weight
(This was a bit different as usually they ask what will increase the distance)

What is the effect of asymetric thrust (cant remember if it specified a single engine or not) in a low speed climb?
Answers: Yaw left, Yaw right, (I think the others were pitch up or down)

The tourque effect of a right handed propellor will try to?
Answers: Roll the a/c left, roll it right, yaw it left, yaw it right
(I cant remember if it said the a/c was on the ground or in the air and I did hear some students discussing this Q after the exam and one was making the point that the a/c was on the ground and would therefore Yaw left)

Longitudinal stability is provided by ?
Answers a) Larger wings
b) CG ahead of neutral point
c) Wide range of trim speeds available

What is the effect of an aft CG?
Answers were a mix of - inc/decrease longitudinal stability and inc/decrease control movement for a required control surface response

Which of the following statements is correct with regard to the stall speed?
Answer: a) Decreases with decreasing wing sweep angle
b) Increases with decreasing sweep angle

Movement around the lateral axis is?
Answer: a) Pitch
b) Yaw
c) etc...

The whole a/c polar diagram is a graphical representation of?
Answer - Cl/Cd

Principle of operation of a vortex generator?
Answer: - Introduces freestream air into the boundary layer
(slightly different wording than the same feedback question from Bristol & Oxford but the other options were no good)

Which is used in powered control systems with a manual reversion capability?
Answer a) Balance tab
b) Servo etc....etc....

In straight and level flight, induced drag varies (may have said proportional or similar) with?
Answer: a) 1/V squared
b) V2...etc...etc

Short period is oscillation around?
Answer: - The lateral axis

The question about a turn using roll spoilers with speed brakes extended and the movement of the spoilers.
Answer: a) Moves on upgoing wing only (may have said moved up on the upgoing wing only)
b) Moves on down going wing only (may have said moved up on the downging wing only)
c) Moves up on the down going wing & down on the upgoing wing

(The question definately did not state whether the spoilers were differential or non differential and in this case there were two valid answers - b & c. would it be worth appealing this question for making an assumption about the most common type of arrangement?)


A feathered prop gives?
Answer - minimum drag

Flaperons are a combination of which controls?
Answer - flaps and ailerons

The extreme right of the gust envelope diagram is which of the following speeds?
Answer: VD, VMO,....

The speed that the shock wave travels over the ground?
Answer: a/c ground speed

What is the effect of a CG to the rear of the aft limit?
Answer: It provides an unacceptably low level of stick force stability
(This was the answer I chose as non of the others were relevant - though I cant remember now what they were)

Which has the minimum stall angle?
Answer: Low speed stall / accelerated stall / shock stall / deep stall
(Every other time I have seen this question it has said which has the highest critical angle)

A high aspect ratio wing will?
Answers: A mix of inc/reduce induced drag & inc/reduce critical AoA

Compared to an a/c in straight & level flight, an a/c at the stall will have...
Answer: A mix of inc/decrease lift & inc/decrease drag

The gust load question regarding whether the load will increase or decrease with increasing/decreasing weight and altitude.


What can be determined by the L/D ratio
Answer: The horizontal distance covered in a glide from a given altitude in still air

What is the effect of an increase in altitude or temperature on Vmca?
Answer: Vmca will decrease due to engine thrust decreasing

What is the function of the stick pusher?
answer: It activates and pushes the stick forward at or beyond a certain AoA

Which wing produces most lift at the root?
Answers were the usual selections

A shock wave will first make an appearence..?
Answers: Wing upper surface / lower surface / Leading edge / Trailing edge

The question about more into wind aileron being required in a X-wind landing in an a/c with excessive lateral stability.
Straight from the feedback.


Does it bring back any bad memories?
