Radio Orientation

Question 0

What is reverse sensing?

Answer 0

When VOR needle indicates the reverse of normal operation.

When Flying inbound on backcourse or outbound on front course of an ILS reverse sensing will occur.

Question 1

What angular deviation from VOR course is represented by half scale deflection of CDI?

Answer 1

Full-scale deflection = 10°:

half scaled the deflection = 5°

Question 2

What is the procedure for determining an intercept angle when intercepting a VOR radial?

Answer 2

Turn to heading to parallel desired course, same direction as course to be flown.
Determine difference to be intercepted.
Double the difference. Not less than 20° nor greater than 90°.
Rotate OBS and turn to intercept heading.
Hold heading until CDI centers, follow tracking procedures inbound.

Question 3

What degree of accuracy can be expected in VOR navigation?

Answer 3

VOR navigation is accurate to ± 1°

Question 4

How do you find an ADF magnetic bearing?

Answer 4

Magnetic heading + relative bearing = magnetic bearing
