Question 1

longitude

Answer 1

lines that go up and down

Question 2

latitude

Answer 2

lines that go horizontal parallel to the equator

Question 3

deviation

Answer 3

error in magnetic compass direction

Question 4

variation

Answer 4

difference between true and magnetic direction

Question 5

DMR

Answer 5

designated mountainous regions:

DMR 1 & 5
B.C. is 1, and norther islands (buffin) 5:
both are 2000ft mountain clearance

DMR 2,3,&4
east coast, 1500ft obstacle clearance

non-mountainance region:
parries, 1000ft clearance

Question 6

ADF

Answer 6

automatic direction finder

uses NDB, non direction beacon

Question 7

calculating bearing to an NDB

Answer 7

bearing to station (BTS) = magnetic (MH) + relative bearing (RB)

Question 8

VOR accuracy requirements

Answer 8

the acceptable tolerance is plus or minus 4º

Question 9

minimum satellites for GPS

Answer 9

4

Question 10

GPS constellation

Answer 10

24 satellites

for a 3d position, 4 variables must be solved:

1. latitude
2. longitude
3. altitude
4. time

accurate within 6 meters horizontally, 8 meters vertically 95% of the time. or 25 ft

Question 11

vor range calculation

Answer 11

square root of the hight of the receiver x 1.23
+
square root of the hight of the transmitter x 1.23

example

vor located at 1500 ft, aircraft at 4500 ft
√ 1500x1.23 + √4500x1.23= 130
