b. Tune and identify the appropriate navaid.

c. Check the VOR/TACAN switch in the proper position.

d. Twist the final approach course into the IND-350.

e. Follow radar vectors given by Approach Control.

f. If a lower altitude is assigned, perform a terminal descent.

g. When aircraft position is within ten NM of the field (five NM of FAF on TACAN

approach), 30 radials and heading within 90 degrees of FAC, slow to 120 knots.

NOTE: If established in a terminal descent and heading within 90 degrees of FAC when within

10 NM and 30 continue descent at 150 knots until reaching assigned altitude then slow to 120

knots.

APP CONT: "Navy Turbo 11, Pensacola Approach, now 5 miles from the final

approach fix, turn right heading 235, maintain 2200 until established

on final, cleared for the TACAN 25L approach to Navy Pensacola.

Contact Sherman Tower local channel 4."

SNFO:

"Turbo 11, right to 235, cleared for the approach, leaving 3000 for 2.2,

switching tower."

Switch to 340.2 and contact tower as follows:

"Sherman Tower, Turbo 11, 10 DME,TACAN final."

SNFO:

TOWER:

"Navy Turbo 11, Sherman Tower, roger, report the final approach fix

runway 25L."

SNFO:

"Turbo 11, WILCO"

h. Maintain assigned altitude and heading until you have intercepted the final approach

course; i.e., established the aircraft on a segment at a published approach procedure.

i. Once cleared for the approach and established on either the inbound course or a

shallow intercept, transition to BAC and perform the landing checklist.

j. Once the BAC transition is complete, the remaining procedures are identical to those

on previously introduced approaches.

NOTE: If the controller vectors you through the final approach course without explanation, you

should query him regarding the reason. Such a vector may at times be necessary but should be

previously explained by the controller (e.g., "vectors across the final approach course for

sequencing."

Common - Errors

1. Poor orientation. Be aware of your position. You must transition to 120 knots within 30

of the final approach course and ten NM of the field (5 NM of FAF on TACAN approaches).

2. Failing to intercept the final approach course once cleared to do so. Be alert for CDI

movement and lead the turn sufficiently to roll out on course.
