Enrotue navigation

Question 1

DR navigation

Answer 1

Dead-reckoning or deduced reckoning

Question 2

DR meaning

Answer 2

Navigation by time and distance travelled rather than using landmarks or astronomical observations

Question 3

What is a “fix” in DR?

Answer 3

Can be a starting point for the DR navigationn (because its known)
or a geographical position of an aircrtaft determined by visual reference to the surface, or by radio nav equipment

Question 4

What is a “pinpoint” in DR?

Answer 4

Ground position of an aircraft determined by direct observation of the ground and NOT BY radio nav equipment

Question 5

TMG

Answer 5

Track made good

Question 6

TE

Answer 6

Track error, difference between the desired track and actual TMG

Question 7

When does a track error likely to happen?

Answer 7

When wind differs in speed / direction

Question 8

Enroute check abbreviation

Answer 8

FREDA

Question 9

FREDA meaning

Answer 9

Fuel, Radio, Engine, Heading indicator, Altitude

Question 10

FREDA -F

Answer 10

Fuel: on and suffiicent
Fuel tank: Usage monitored
Mixture: Learned as required for the cruise
Fuel pump: as required

Question 11

FREDA - E

Answer 11

Engine: Oil temp and pressure within limits.
Carb. heat if required.

Question 12

ATD

Answer 12

Actual time of departure

Question 13

ETI

Answer 13

Estimated time intervals

Question 14

FREDA -H

Answer 14

Heading: on desired course,
HI is aligned with magnetic compass (important, between 10-15 minutes every time)

Question 15

When FREDA should be done

Answer 15

between 10-15 minutes

Question 16

is track made good the desired track? by definition

Answer 16

No

Question 17

Closing angle

Answer 17

When offtrack, this is the angle required to get back to desired track

Question 18

Estimating track errors

Answer 18

My using track guides (fan lines)
Or 1-in-60 rule

Question 19

Track guides (fan lines)

Answer 19

Drawing 10-5° lines from checkpoints. After determining a “fix” in this area during flight, can easily estimate the required heading (TE+ CA) to be bakc on desired track (page 208)

Question 20

1-in60 rule

Answer 20

If traveled 60 miles then an error in track of one mile is 1° error in heading (TE)

Question 21

If I am 8nm off-track, and traveled 60nm, what is te TE?

Answer 21

8°

Question 22

If I am 4 nm off-track in 30nm, what is TE?

Answer 22

8°

Question 23

What will be the relation to the desire track if only TE is fixed?

Answer 23

parllel

Question 24

How to determine CA?

Answer 24

Same 1-in-60 rule

Question 25

Higher CA will?

Answer 25

Make you back to track more sooner

Question 26

Ratio method and inverse ratio method for TE

Answer 26

REVISE page 214

Question 27

What is a common unplanned diversion procedure to take. (Like overtakign a thudnerstorm)

Answer 27

• Turn heading by 60, and log the time the flown
• Parllel the track by turning 60 degrees back to original hading (note the time flown)
• Return at 60 degreees for the same time to return to track
• Take a suitbale HDG to stay in track

Question 28

10 nm thumb times by speeds

Answer 28

120kt = 5 min
100kt = 6 min
85kt = 7.5 min
70kt = 8.5 min
60kt = 10 min

Question 29

Use thumb times. Diversion of 30nm at GS 100kt will take?

Answer 29

18 minutes
(3 * 6)

Question 30

Flying between two points 120nm apart.
After 40mn aircraft is found to be 5nm right of the track
What correction is needed to overhead point B?
use inversion ratio method

Answer 30

11 left

Question 31

Number of eavailable transponder squawks

Answer 31

4096

Question 32

Transponder frequency

Answer 32

1030MHZ 1090MHZ
