Point-To-Point (IAF to IAF)

T-45C TS INav-08

Fuel, Weather, and Alternate Airfield Planning

One may use a pencil laid on the HSI to approximate the computer's output. The computer can be used to

determine the course and distance from the IAF at your destination to the IAF at the alternate as follows.

Point-To-Point (IAF to IAF)

On the front side, lower portion of the Jet

Flight Log are spaces for cruising from

destination Initial Approach Fix (IAF) to

the alternate Initial Approach Fix. The

“Wind Side” of the Navigation Computer

can be used to determine magnetic

course and distance for this leg of the

flight using a common feeder facility for

the two IAF navigation facilities.

Step 1

Using forecast winds, determine

appropriate Approach Procedure Charts

for the probable runways in use at

destination and alternate, based on

forecast surface winds.

EXAMPLE:

Destination:

New Orleans NAS

Alternate:

Pensacola NAS

Figure 7: NAS NEW ORLEANS APPROACH

Step 2

Locate a NAVAID common to both

Approach Procedure Charts which have

“Feeder Routes” to the two IAFs.

EXAMPLE:

Semmes VORTAC is depicted on both

charts with “Feeder Routes” to the

Pensacola and New Orleans IAFs.

NOTE: “Feeder Routes” bearing and

range are to the IAF, NOT the holding fix

or the NAVAID.
