INSTRUMENTS FLIGHT PLANNING
ALTERNATE - Your alternate airfield's name and its three-letter identifier.
ROUTE - The route you fly to your alternate.
ALTITUDE - Selected altitude to alternate. Leave blank.
FUEL - Leg fuel to your alternate. Leave blank.
TIME - The ETE to your alternate. Leave blank.
ALT ELEV - Alternate airfield elevation.
APC CONT - Approach control frequency serving the alternate airfield.
TOWER - Tower frequency.
GND CONT - Ground control frequency.
In the T-34C/T-6A, you plan three separate profiles to your alternate: cruising altitude, 5000
feet, and Bingo. The following example is for a T-34C profile.
The cruising profile is planned from destination IAF to alternate IAF at cruising airspeed and
altitude. Enter this information on the line above the word 'Alternate' on the jet log as seen in
Figure 1-17. Writing across, you start with the direct symbol followed by the radial/DME of the
IAF. Our alternate airfield is NAS CECIL FIELD and its IAF is NZC 355011. Cecil's TACAN
channel is 88. The course from the VAD 005010 to the NZC 355011 is 122°. Plot each of these
points on your enroute chart and measure the distance and magnetic course between them. The
distance is measured in a similar manner.
Finally, in the NOTES section, disregard the printed FRCST ALT, and list parameters under
which you would fly to your alternate (i.e., your TAS, Fuel Flow, and Altitude).
Split line entries are not necessary in the ALTERNATE section.
The ETE and leg fuel are calculated in the same manner that they
were in the ROUTE OF FLIGHT section.

The second alternate profile is planned at 5000 feet MSL from destination IAF to alternate IAF.
At 5000 feet, the associated airspeed remains at 190 KTAS. This altitude has a fuel flow of 283
pounds per hour. Remember that the winds at 5000 feet are 220/20.
