Question 1

On a modern jet aircraft, why would you chose an engine design with an axial flow compressor vs. centrifugal flow compressor? I wasn’t sure, but I answered Options were 1) higher pressure ratio, and higher efficiency 2) higher pressure ratio, lower efficiency 3) lower pressure ratio, higher efficiency 4) lower pressure ratio, lower efficiency 

Accepted Answer

1) higher pressure ratio, and higher efficiency

Question 2

You are at FL 330 and at mach .76. Told to descend to 10,000 at current speed then 330 knots (question was worded really weird). When would your airspeed change from .76 to 330KIAS as opposed to .75 to 250KIAS? 

Accepted Answer

I put would transition to 330KIAS at higher altitude. Not sure if that’s right but I think it is. NOT SURE IF THAT IS CORRECT. RST HAS A TEST QUESTION THAT IS SIMILAR WITH A DIFFERENT ANSWER (I THINK TEST 2 OR 3). THE ONLY WAY I CAN SEE THIS AS BEING CORRECT IS THE DIFFERENCE BETWEEN .76 (.76 X 6 = 356) AND 330KT. IS ONLY 125KNOTS. SO IT MAY BE REACHED AT A HIGHER ALTITUDE AS OPPOSED TO .75 (.75 X 6 = 450) AND 250 THE DIFFERENCE BEING 200 KNOTS.

Question 3

Why is stall recovery more difficult at higher altitudes?

Accepted Answer

Less thrust avail during recovery (one answer that I almost chose was less air available over wing, but I think that the thrust answer was correct

Question 4

What do you do in case of a compressor stall?

Accepted Answer

Only logical answer was ‘comply with procedures in POH’ 

Question 5

When is a compressor stall most likely?

Accepted Answer

Low airspeed and an increase in power

Question 6

Dehaveland Comet design flaw

Accepted Answer

(WTF??)? Metal Fatigue. Luckily gouge had this question in it already

Question 7

Winds 360/20, land on 27 or 9 with left engine dead.

Accepted Answer

Land on RWY 27 since dead engine is downwind. RWY 27 is correct but was on two of the answers, it wanted to know WHY (I put helps counteract crosswind weather vaning I think, something to that effect

Question 8

Factors that effect turn radius?

Accepted Answer

Velocity and load factor ACTUALLY IT IS VELOCITY AND BANK ANGLE.

Question 9

What does a Generator Control Unit do?

Accepted Answer

Fairly obvious answer but it was ‘monitors volts and freqs and keeps generator connected to bus’. One answer that could have led astray was the definition of a constant speed drive

Question 10

What is NOT a design in modern fuel systems?

Accepted Answer

Answers were: a)can gravity feed b)uses electrical fuel pumps continuously to feed engine c)can crossfeed to counteract inbalance d)(forget, but something obvious like the use of engine driven pump)….. a)can gravity feed

Accepted Answer

50 minutes.

Question 15

Have 12,500 pounds gas, fuel to alt 3,000 pounds, FAA min at alt is 4,500.

Accepted Answer

How long can you hold for? It phrased this question saying I was 20 miles from hold, and entering holding at 1700Z. When can you hold until? GUESS: 12,500 - 3,000 - 4500 = 5,000 THATS HOW MUCH HOLD FUEL YOU HAVE. LETS SAY YOU ARE BURNING 6,000 LBS PER HOUR. 5,000/6,000 = .83 X 60 TO GET MINUTES IS ABOUT = 50MIN OF HOLD TIME.

Question 16

At 6NM you are 1 degree of LOC track. How far off course are you?

Accepted Answer

1NM is answer I think

Question 17

Coming in to land at MIAMI from the EAST. When must you slow to 250?

Accepted Answer

I think this was a trick question because two options were: a)@ 10,000 feet b)@ 10,000 feet and 12NM from shore (ADIZ). I didn’t recall a speed restriction at ADIZ so I answered @10,000’

Question 18

Increasing tailwind shear on final. What happens?

Accepted Answer

A)raising flaps quickly with boost pumps off b)moving tiller back and forth quickly at high airspeeds c)lowering gear on climbout d)raising flaps after landing….I answered A since it seemed most logical but I’ve never heard of that before

Question 22

On takeoff roll, EPR is set for takeoff but N1 is only 80%. What do you do?

Accepted Answer

Answer is abort takeoff since possible icing on probes

Question 23

Accepted Answer

Compressor, combustion section, inlet, or exhaust? I answered compressor section

Question 24

Thrust and drag are equal when?

Accepted Answer

Level, unaccelerated flight

Question 25

Tricky question: What is the basic philosophy behind an electrical fire?

Accepted Answer

Narrowed it down to only two answers that seemed logical: a) isolate source to eliminate fire and continue flight OR b) descend, land as soon as possible. I answered land as soon as possible, however I could have been wrong. I know you try to isolate an electrical fire but I chose the ‘safest’ answer.

Question 26

Jumpseater says he sees and smells smoke. What do you do?

Accepted Answer

Don oxygen and smoke goggles. Other answers that ‘appeared’ right were: descend and declare and emergency, stuff like that. But get O2 on first….

Question 27

When declaring emergency fuel…which of the following is NOT correct?

Accepted Answer

A)you are declaring an emergency b)you must land immediately or fuel starvation c)you can accept minor delays d)ATC should give you priority…Has to be C

Accepted Answer

NOSE WHEEL LIFT OFF

Question 38

When slow down (“it takes 1Nm per 10kts”)? Conditions: Vapp 130, currently 1600’AGL & 230Kts, do not want to use config (gear) due to noise and passenger comfort. A. 7, 15, 23, or 30+; 15 made most sense to me

Accepted Answer

?

Question 39

Mach defined? A. Dude said most likely answer was velocity/speed of sound

Accepted Answer

Mach number is a ratio of the speed of a body (aircraft) to the speed of sound in the undisturbed medium through which the body is traveling. It is said that the aircraft is flying at Mach 1 if its speed is equal to the speed of sound in air (which is 332 m/s or 1195 km/hr or 717 miles/hour.) An aircraft flying at Mach 2 is flying at twice the speed of sound in air, etc.

Question 49

You are at your EFC holding and it is 1730Z flying a 2-engine jet aircraft. How long can you continue to hold for before you must go to alternate? (it wanted the Z time that you must leave holding) Current fuel: 12,000, time/fuel to alt 30 min, 3,000 lbs, required reserves at alt: 4,000 lbs fuel burn is 3,000/engine….I may be messing up the numbers, but you get the point.

Accepted Answer

Two answers that could have been right (decrease landing distance or increase descent rate for a given airspeed), I chose decrease landing distance

Question 55

Where (specifically) does a compressor stall occur? I forget answers but they were all parts of the engine but not one ‘general’ section (i.e., compressor), they were like ‘stator vanes, turbine fans, inlet guide vanes’… stuff like that, just read up on compressor stalls.
