Question 5

Instrument cross-check is the technique used to maintain control and monitor the performance of the aircraft. Which instrument does the cross-check originate from?

Answer 5

The cross-check originates from the EADI. The cross-check pattern varies for different maneuvers.

Question 6

Answer 7

a. For turns of less than 30º of heading change, your bank angle should equal your degrees of turn.
b. For turns of 30º or greater, use a bank angle of 30º.

Question 8

Constant rate climbs and descents are performed by varying pitch and power to maintain a _____ and _____.

Answer 8

Specific airspeed and climb/descent rate

Question 9

Power controls airspeed and pitch controls rate of climb or descent. If you are flying at 240 KTAS with a 3° nose down pitch, what will the VSI read?

Answer 9

1200 feet/minute

a. The change in VSI per degree of pitch change = TAS (NM/MIN) x 100
b. To solve this, multiply 240 KTAS/60 x 100 x 3° = 1200 feet/minute

Question 10

Question 11

How will you recognize an unusual attitude?

Answer 11

An unusual attitude picture on the EADI or unusual indications on your performance instruments

Question 12

What is a radial?

Answer 12

A radial is an imaginary line extending outward from a VOR or VORTAC. It is a magnetic bearing measured in degrees.

Question 13

What is a course?

Answer 13

A course, in radio instruments, is the desired track to or from a navigation aid. Like radials, courses are also measured in degrees.

Question 14

What is the difference between an outbound intercept and an inbound intercept?

Answer 14

a. An outbound course intercept will take you from a station. It is the same as a radial intercept.
b. An inbound intercept is intercepting a course that will take you to a station. For inbound intercepts, take the reciprocal of the radial.

Question 15

What is the difference between homing and proceeding direct?

Answer 15

a. Homing is the simplest way to go from station to station by placing the bearing pointer to the top of the station. This is not an efficient method.
b. Proceeding direct is flying a wind- corrected heading to maintain a course.

Question 16

What methods will assist you in determining a good outbound radial intercept heading?

Answer 16

a. The 45º intercept method
1) TDC + 45 (Tail to the Desired Course + 45, not to exceed the tail of the bearing pointer)
b. Double the angle method
1) Double the difference between the tail of the bearing pointer and the new course to determine an intercept angle.

Question 17

What methods will assist you in determining a good inbound intercept heading?

Answer 17

a. Course to bearing pointer + 30 (Charlie Brown +30, not to exceed 90)
1) Turn to a heading 30º beyond the bearing pointer position (not to exceed 90º intercept angle)
b. Double the angle method
1) Double the difference between the head of the bearing pointer and the new course to determine an intercept angle

Question 18

You are on the 165° radial at 20 NM and need to go to the 260° radial at 20 NM. What approximate heading will you use?

Answer 18

a. Set the desired radial in the course select window
b. Turn in the shorter direction to a heading between the head of the bearing pointer and the head of the course arrow.
c. Refine your initial heading
d. Your heading should be 300-310º (no wind)

Question 19

You are on the 090° radial at 20 NM and need to go to the 350° radial at 100 NM. What approximate heading will you use?

Answer 19

a. Set the desired radial in the course select window
b. You are already heading in the general direction toward the desired fix
c. Refine your initial heading
d. Your heading should be 335°-345° (no wind)

Question 20

You are on the 300° radial at 25 NM and need to go to the 210° radial at 75 NM. What approximate heading will you use?

Answer 20

a. Set the desired radial in the course select window
b. Turn in the shorter direction to a heading between the head of the bearing pointer and the head of the course arrow.
c. Refine your initial heading
d. Your heading should be 185°-195° (no wind)

Question 21

You are on the 030° radial at 50 NM and need to go to the 270° radial at 30 NM. What approximate heading will you use?

Answer 21

a. Set the desired radial in the course select window
b. Turn in the shorter direction to a heading between the head of the bearing pointer and the head of the course arrow.
c. Refine your initial heading
d. Your heading should be 225°-235° (no wind)

Question 22

How can ETA be estimated using the EHSI?

Answer 22

a. Estimate the distance between the two fixes using the distance from the center to the outer edge of the EHSI as a scale.
b. Divide the estimated distance by the groundspeed in miles per minute to determine the time needed to travel to the new fix and ETA.

Question 23

How do you fly an arc intercept from a radial?

Answer 23

a. TIM the station
b. Determine the direction of turn
c. Determine your lead point in nautical miles.
d. At the lead point, turn to place the head of the bearing pointer on the 90° index and check your DME.

Question 24

You are inbound to a VORTAC on the 060° course at 35 NM. Your groundspeed is 180 knots. What is the lead point for a left turn to intercept the 25 NM arc?

Answer 24

In this case you would use your nautical miles per minute (NM/Min) – 2 to determine the turn radius for the 90° turn. You would, therefore, need to start your turn 1 NM before reaching 25 NM, or at the 26 DME.

Question 25

How do you intercept a radial from an arc?

Answer 25

a. Lead point in radials = (NM)*(60/ARC DME)

b. Begin your turn when you are this number of radials from the desired radial.

Question 26

You are arcing left on the 15 NM arc. Your groundspeed is 200 knots. What is the lead radial for a turn to intercept the 045° radial outbound?

Answer 26

At 200 knots groundspeed, your turn radius is approximately 1.5 NM. At 15 NM DME your ground track equals 4° per NM. A 1.5 mile lead point would therefore cover 6 radials, and you should start your turn at the 051° radial.

Question 27

What is the control and performance concept?

Answer 27

a. Establish attitude and power settings
b. Trim out control pressures
c. Cross-check the performance instruments
d. Adjust attitude or power settings as necessary

Question 28

What is the concept for dealing with an unusual attitude indication?

Answer 28

Recognize – Confirm – Recover

The EADI

Question 30

True or false? All cross-checks use the hub and spoke method as a base.

Answer 30

TRUE

Question 31

True or false? For turns of 20° or less, your bank angle should equal your degrees of turn. For turns of greater than 20°, use a bank angle of 30°.

Answer 31

FALSE
For turns of 30° or less, your bank angle should equal your degrees of turn. For turns of greater than 30°, use a bank angle of 30°.

Double the angle method

Question 35

How do you determine a lead point for your turn in an arc intercept?

Answer 35

Use your speed in NM/Min – 2 or (Mach X 10) - 2 as a lead point.

Question 36

Where should the imaginary line be placed on the compass card in a fix-to-fix procedure? How do you use this line?

Answer 36

The imaginary line is from the aircraft present position to the intended fix. Slide this line to the center of the EHSI and turn to this heading.
