3.9.7 TAWS B Enable

Follow this procedure to re-activate the TAWS Class B option. A TAWS Enable Card, as specified on

General Arrangement Drawing, listed in Table 1-2, will be required for this procedure. Section 3.9.8

installs the Terrain/Obstacle database card.

NOTE

The G1000 has various features that require the use of unlock/enable cards to activate the feature.

Throughout this document these cards are generically referred to as ‘enable cards’. In some cases, the

actual label on the physical card may say ‘unlock’. If uncertain, the technician should verify the card part

number prior to use.

NOTE

When the TAWS option is enabled for the first time (normally with the initial STC installation), the

G1000 writes its unique system ID to the physical card and locks the files to this unique ID. This

prevents the enable card from ever being used to activate TAWS in another G1000 system. This enable

card is tied to the specific aircraft in which it was used for the first time. For situations where TAWS

must be re-activated, this card must be used.

1. If not applied, apply power to the G1000 system.

2. Remove power from PFD 1, PFD 2 and MFD by opening the PFD 1 PRI/SEC, PFD 2 and MFD

circuit breakers.

3. Insert the TAWS Class B Enable card in the upper slot of PFD 1.

4. While holding the ENT key on the PFD 1, PFD 2 and MFD (for MFD press and hold the farthest

right pushbutton), restore power to the displays.

When the words appear in the upper left corner of the displays,

release the ENT key

6. On PFD 1, go to the System Upload page using the small PFD 1 FMS knob.

7. Activate the cursor. Use the small PFD 1 FMS knob to select CONFIGURATION FILES in

the AIRFRAME field and press the PFD 1 ENT key.

8. Highlight the FILE field. Use the PFD 1 small FMS knob to select the ‘Enable TAWS’ option

and press the PFD 1 ENT key. Once the option is selected, the configuration files in the

PRODUCT field will be displayed. All files should be checked. If not, press the CHK ALL

softkey.

9. Press the LOAD softkey.

10. Monitor the status of the upload. When the upload is finished, press the PFD 1 ENT key to

acknowledge the upload complete confirmation.

11. View the SUMMARY field and ensure that the item is ‘COMPLETE’.

12. De-activate the cursor.

13. Power down the system and remove the TAWS Enable card from PFD 1.
