System Review (FOM Radar Use) (Deep Dive)

Question 1

Normal Antenna Position (NAP)
(FOM 4.9.2.1)

Answer 1

Radar Fault Monitoring
Best Threat Identification
Optimal Terrain Mapping
Optimal Shadow Identification
Minimal Workload

• Scale is set at 4x the altitude in thousands of feet. [ex. 10,000’ = 40 miles]
• Tilt so ground return is 2.5 times the altitude in thousands of feet. [ex. 10,000’ = 25 miles]

Question 2

Calculating Scale (FOM 4.9.2.1)

Answer 2

4 x altitude in thousands of feet.

Question 3

Tilt (FOM 4.9.2.1)

Answer 3

Set to obtain terrain return at a distance of 2.5 times the altitude in thousands of feet.

Question 4

Threat Identification Position (TIP) (FOM 4.9.2.2)

Answer 4

A tilt position in which the radar beam is parallel to earth surface. Normally 4 degrees above Normal Antenna Position (NAP).

Question 5

Tilt Management Takeoff (FOM 4.9.2.3)

Answer 5

Takeoff Scan from 0 degrees to full up and then set at 5 degrees up.

Question 6

Tilt Management Inflight (FOM 4.9.2.3)

Answer 6

Set tilt for Threat Identification Position (TIP)

Rotate tilt up until echo disappears or down until it appears. Note tilt angle change and distance to echo.

Question 7

Altitude Difference between Echo top and Aircraft Flight Level (FOM 4.9.2.3)

Answer 7

Tilt Angle Change x Distance to echo x 100

Question 8

Scale Management (FOM 4.9.2.4)

Answer 8

Takeoff normally set scale 40 nm.

To gain a greater perspective (e.g. big picture): Use large scales.

To circumnavigate cells: Use smaller scales as necessary.

Question 9

Gain Management (FOM 4.9.2.5)

Answer 9

To determine cell severity:

Observe echo with gain in AUTO.

Reduce gain until the size of the echo is the same as the size of the red area prior to reducing gain.

If any red is still displayed, the cell is level 5 (Intense.)
