PPL General

Question 1

Speed for maximum endurance?

Answer 1

Speed that consumes the less fuel

Question 2

What is the compass lubber line?

Answer 2

Line showing aircraft heading on the compass

Question 3

What is pre-ignition

Answer 3

Fuel/air mixture ignited too soon because of hot carbon particles

Question 4

What will VSI indicate if static source is blocked?

Answer 4

Level flight

Question 5

What is Newton’s third law

Answer 5

When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction to the first body.

Question 6

What is lift formula?

Answer 6

Lift = Cl x p/2 x V^2 x S

Question 7

List radio readability scale (1 to 5)

Answer 7

1. unreadable;
2. readable now and then;
3. readable with difficulty;
4. readable; and
5. perfectly readable.

Question 8

What is slow flight?

Answer 8

Slow flight is the speed range between stalling speed and the speed for maximum
endurance.

Question 9

Ground to air visual sign one need Fuel or Oil?

Answer 9

L

Question 10

To which pressure source is the altimeter connected?

Answer 10

Static source

Question 11

In the turn coordinator gyroscope, the supporting ring (gimbal) of the rotor is ___ to the longitudinal axis of the aircraft.

Answer 11

Tilted 35 degrees

Question 12

What does the mixture controls?

Answer 12

The amount of fuel sucked by the nozzle

Question 13

Wing tip vortices rotation from behind?

Answer 13

Clockwise on left, anticlockwise on right

Question 14

Sign of carburetor icing on variable pitch propeller?

Answer 14

Decrease in manifold pressure

Question 15

Ball + turn on same side= slipping or skidding?

Answer 15

Slipping

Question 16

Formula to determine aircraft balance

Answer 16

Weight = moment / moment-arm

Question 17

Static port blocked.

What will Altimeter do?

Answer 17

Stop moving

Question 18

What instrument does pitot tube blockage affects?

Answer 18

Only Airspeed indicator

Question 19

Complete pitot blockage. What will airspeed indicate during climb/descent?

Answer 19

Will act like an altimeter.

Question 20

What will happen to altimeter if partial blockage of pitot tube?

Answer 20

slowly decrease to zero

Question 21

Name of speed bottom of white arc

Answer 21

Vs0 (power off, full flaps, stall speed)

Question 22

Name of speed on the Altimeter

Answer 22

IAS (Indicated Airspeed)

Question 23

What is CAS

Answer 23

Calibrated Airspeed

IAS corrected for Positional Error

Question 24

Rule of thumb to correct CAS for altitude and temperature?

Answer 24

add 2% to IAS for every 1000ft of pressure altitude increase

eg. 6000ft with 100kt → (6x2=) 12% to 100kt = 112kt.

Question 25

How will Airspeed react if pitot is blocked during climb?

Answer 25

Airspeed will increase (over-read) during a climb

Question 26

How will Airspeed react if pitot is blocked during descent?

Answer 26

Airspeed will under-read during descent

Question 27

What happens if static system is blocked? - Altimeter - VSI - Airspeed indicator during descent - Airspeed indicator during climb

Answer 27

- Altimeter → frozen - VSI → constant zero - Airspeed indicator during descent → over-read (increase) STALL RISK - Airspeed indicator during climb → under-read (decrease)

Question 28

What happens to Airspeed indicator for partial leakage?

Answer 28

Slowly goes to zero

Question 29

What is "clean configuration"

Answer 29

Flaps and gear retracted

Question 30

Altimeter: What is the name of bottom of green arc?

Answer 30

Vs1: Power off stalling speed clean configuration

Question 31

Airspeed: name of upper limit of green arc

Answer 31

Vno: Maximum structural cruising speed

Question 32

Formula for bank angle stalling speed

Answer 32

Vst = Vs * sqrt(load_factor)

Question 33

As the CG moves ___ (forward/rearward) the stall speed ___ (increases/decreases)

Answer 33

As the CG moves forward the stall speed ___ increases

Question 34

An increase in weight ____ the stalling airspeed (increases/decreases). Why?

Answer 34

An increase in weight increases the stalling airspeed. Because wing will fly at higher AoA for the same airspeed as compared to when it is lightly loaded. Will reach critical AoA sooner.
