Introduction to Basic Instruments

T-45C TS & ADV BIFP-02

F. Radar altitude

1. Location: on the ADI display

2. Purpose:

a. Provides visual and audio warning at selected

altitudes

b. Displays aircraft altitude above terrain (AGL)

IV. Scan techniques 2.5.12.1.1

A. Traditional and modified spoke scan: Distributes pilot’s time

among all or most flight instruments with the ADI as the hub of

the scan

B. Maneuver-specific scan

1. ADI is primary control instrument for transitions

2. Digital cockpit scan simplifed because performance

indications are located on the ADI display

3. Method requires knowledge of what instruments are

necessary to perform the maneuver (e.g., straight and

level, roll-in, maintain turn, roll-out, etc.)

4. Emphasis placed on ADI with performance instruments

cross-checked for desirable/undesirable readings

5. More efficient and emphasizes specific instruments

V. Entering instrument mission data 2.7.8

A. On start system navigation information initializes to:

1. Navigation control -- forward cockpit

2. HSI display -- Planimetric

3. No steering selected
