T-39 FLIGHT PREPARATION STUDENT GUIDE
A-4
• Turn point procedures are expected to be performed at all fixes and NAVAIDS,
including departures and approaches (may be modified in climb/descents by omitting
ETA’s and EFRs, for example - “Two minutes prior to CANUE, outbound heading
186 for a course of 180”)
• For climbs, descents, or initial level off, the student may use KTAS or KIAS in
figuring ETA’s (IMN X 10 will give a rough TAS in NM per MIN, e.g., .5 IMN = 5
NM/min = 300 KTAS).
• At least 3 “complete” turn points at altitude are required to complete any ANAV.
• Students should plan 2 PT-to-PTs on each ANAV sortie. These may include
intersections on SIDs or Approaches and will satisfy the “complete” turn point
requirement if done at altitude.
n. Turn Point Procedures
• (2 Min prior) Outbound heading XXX for course XXX (Direct/Jet Route), ETA to
_____ is xx+xx, description of jet route or next turn point.
• (MOT) Left/Right XXX (clear turn), time, place, fuel, NAVAID
• (Wings-Level) Fuel + preflight, Fuel at the IAF is _____
NOTE: Lead all turns on airways and direct (i.e. TACAN to TACAN) routes, including PT-PT’s.
o. Ground Speed Checks
• One ground speed check shall be accomplished on the first leg to validate the ground
speed readout. If the check is within + 10 kts of the readout, the ground speed
readout may be used for the remainder of the flight. Use the HSI button to toggle to
ground speed.
• After ground speed check, update the ETA to the next point and EFR at the IAF
• Update ETAs and IAF fuels on each leg thereafter
• The student shall also verbalize the wind calculated.
p. Basic NAVAID Setup
• TACAN is the primary NAVAID. VOR is a backup. Be flexible – if the situation
dictates that the VOR makes more sense to use first then do it. Example – you are
cleared direct to the Brookley (BFM) VORTAC and then to NPA. Instead of putting
your TACAN on BFM with nothing to put the VOR on to leapfrog the NAVAIDs
(Saufley, 108.8 is a T-34-ism – don’t do it!), and then switching the TACAN again to
NPA, just navigate to BFM with the VOR and have the TACAN already on NPA for
a seamless switch.
• At the change over point on an airway, switch the TACAN and give the pilot a new
heading for the new course.
