1

What is Azimuth?

The angular position or bearing in a horizontal plane usually measure clockwise from true north.

2

What is Bearing?

Defined as angular position of an object with respect to a reference point or line.

3

What is Range?

Defined as the distance of an object from an observer.

4

What is Heading?

Defined as actual orientation of the aircraft's longitudinal axis at any instance.

5

What is True Heading?

Direction measure by true north

6

What is Magnetic Heading?

Uses the direction of the earth's magnetic field at that location as the reference.

7

What is Relative Heading?

Uses the current direction that an object is facing a 0-360 azimuth alignment.

8

What system aids the Inertial Navigation System?

GPS

9

What are the five modes of INS?

STBY- Inactive
NORM- Normal Alignment
STR HDG- Command Stored Heading Alignment
NAV- Navigation
ATT- Attitude

10

How long does it take for INS to align at Normal alignment

3.5 Minutes

11

What are the colors of the Position lights and their location.

Red - Left Wing Tip
Green - Right Wing Tip

12

Anti-Collision strobe lights provide coverage where?

Forward, aft, up, down, outboard

Supply 270 VDC to the IPP for initial startup.

17

What are the three positions of the 28 VDC Battery?

On, Off, Tow

18

What does the Permanent Magnetic Generator supply?

Supplies unregulated 28 VDC to the Converter Regulators (CR).

19

What do the Converter Regulators supply?

Supply regulated 28 VDC to the flight Control channels (A,B,C).

20

What does the Non-Linear Inverter provide?

5.4kA, three-phase 115 VAC, 400 Hz power to the aircraft. There is no system redundancy since the VAC is not flight essential.
