Answer 5

1030MST

Question 6

What is the technique pilotage?

Answer 6

Using visual landmarks outside the cockpit such as checkpoints and landmarks, to figure out location, and compare them to the planned route

Question 7

What is the technique dead reckoning?

Answer 7

• Think of DED (deduced)
• Using numbers such as time, speed, distance, and direction to determine position

Question 8

Using numbers such as time, speed, distance, and direction to determine position is which navigational technique?

Answer 8

Dead reckoning

Question 9

Using visual landmarks outside the cockpit such as checkpoints and landmarks, to figure out location, and compare them to the planned route is which navigational technique?

Answer 9

Pilotage

Question 10

What is ground speed?

Answer 10

True airspeed corrected for wind speed

Question 11

True airspeed corrected for wind speed is know as what?

Answer 11

Ground speed

Question 12

Without wind, what is the relationship between heading and wind?

Answer 12

They equal each other, heading = course

Question 13

With a right crosswind, what is the relationship between heading and wind?

Answer 13

The true course will veer to the left

Question 14

How do you counteract a crosswind to have true course equal true heading?

Answer 14

Turn the nose of the airplane into the wind, otherwise known as crabbing

Question 15

What is the wind correction angle?

Answer 15

The angle between the heading and true course

Question 16

What is the wind triangle?

Answer 16

A method of visualizing heading, true course, and the wind

Question 17

What is the difference between heading and true course?

Answer 17

Heading the direction the nose is pointing and true course is where the aircraft is going over the ground

Question 18

What is variation?

Answer 18

The difference between true north and magnetic north

Question 19

What is calculated to determine heading?

Answer 19

Course + wind correction = heading

Question 20

How is deviation caused?

Answer 20

The magnetic field created by the engine

Question 21

What is the equation to determine magnetic course?

Answer 21

True course ± Variation (-E, +W) = magnetic course

Question 22

What is the equation to determine magnetic heading?

Answer 22

magnetic course ± Wind correction angle (-L, +R) = magnetic heading

Question 23

What is the equation to determine compass heading?

Answer 23

magnetic heading ± deviation = compass heading

Question 24

What is altitude selection based on?

Answer 24

Magnetic course (not heading)

Question 25

If the VFR altitude you fly at is standardized based on which magnetic course you fly, if your magnetic course is between 0° to 179°, what altitude would you fly at?

Answer 25

Odd thousand feel MSL + 500 (3,500 ft, 5,500 ft, 7,500 ft)

Question 26

If the VFR altitude you fly at is standardized based on which magnetic course you fly, if your magnetic course is between 180° to 359°, what altitude would you fly at?

Answer 26

event thousand feel MSL + 500 (4,500 ft, 6,500 ft, 8,500 ft)

Question 27

For standardized VFR altitudes, why is there an additional 500 feet added?

Answer 27

Creates separation between VFR and IFR flights

Question 28

What frequencies do VORs opearte?

Answer 28

108.00 MHz to 117.95 MHz

Question 29

What are radials referenced to?

Answer 29

Magnetic north (not true north)

Question 30

What are the three main types of VORs?

Answer 30

Terminal VFR - 1,000 to 12,000 feet altitude range, 25NM radius Low Altitude VFR - 1,000 to 18,000 feet altitude range, 40NM radius High Altitude VOR - 1st layer: 1,000 to 14,500 feet, 40 NM radius - 2nd layer: 14,500 to 18,000 feet, 100NM radius - 3rd layer: 18,000 to 45,000 feet, 130NM radius - 4th layer: 45,000 to 60,000 feet, 100NM

Question 31

What is the altitude range and radius for a Terminal VOR?

Answer 31

1,000 to 12,000 feet altitude range, 25NM radius

Question 32

What is the altitude range and radius for a Low Altitude VOR?

Answer 32

- 1,000 to 18,000 feet altitude range, 40NM radius

Question 33

What is the altitude range and radius for a Low Altitude VOR?

Answer 33

- 1st layer: 1,000 to 14,500 feet, 40 NM radius - 2nd layer: 14,500 to 18,000 feet, 100NM radius - 3rd layer: 18,000 to 45,000 feet, 130NM radius - 4th layer: 45,000 to 60,000 feet, 100NM
