Location and use of VOR equipment controls and indicators for tuning/identifying

T-45C TS INav 03; ADV INav-01

Use and Operation of TACAN, VOR, VOR/DME

(1) TACAN pointer hunts or rotates

(2) Courseline removed from display

b. DME and identifier signal not affected

2. 40o off bearing TACAN pointer lock-on error: locking on to multiples

of 40o from the desired radial due to inherent operating functions of

the older crystal controlled receivers. Solid state electronics in the

T-45C should preclude this problem from occurring. 2.7.4.2.1

NOTE: Rechanneling the receiver and tuning back to the original

station may remedy the error.

3. Failure to lock on

a. Misalignment of equipment

b. Worn aircraft control box

NOTE: Rechanneling the receiver and tuning from the opposite

direction back to the original station may remedy the error.

4. Co-channel interference: receiving signals (DME, azimuth,

identifier) from more than one TACAN station due to the

relationship between aircraft’s high altitude and station locations

III. VOR

A. Location and use of VOR equipment controls and indicators for tuning/

identifying 2.7.5.1.1.1

1. FWD/AFT option on HSI display selects and identifies which cockpit

controls the HSI display format, and VOR/ILS and TACAN selection

2. Communication control panel: VOR toggle switch provides routing

communication system (ICS) to pilot’s headset

3. VOR/ILS Control Panel

Control Panel

a. Power selector controls power to system and initiates system

BIT when in TEST position

(1) Select VOR steering on HSI display

(2) Set course (CRS) to 000 on HSI display

(3) Set and hold the power/frequency knob in the TEST

position on the VOR/ILS control panel

(4) If the VOR is receiving a valid VOR signal a good BIT

check results in the following HSI indications
