T-39 FLIGHT PREPARATION
RADALT set to 400 feet. All items must be properly set prior to takeoff. This is to include
altitude alerter set to the first level off altitude, CDI set to the first radial, and heading bug set to
the first heading after runway heading.
The Standard Departure Procedures used by jet aircraft at NAS Pensacola are radar
vectors. Complete the first four items of the Lineup Checklist prior to calling for takeoff. When
cleared for position and hold, or takeoff, clear the "groove" (final) and clear the runup area for
FOD, and the runway for other aircraft. Upon receiving takeoff clearance, complete the last two
items of the Lineup Checklist.
Note the takeoff time.
Call "Off the peg"
Call "60 kts"
Call V1 in knots, i.e. "123".
a. After noting a positive rate of climb
Initiate the After Takeoff checklist.
When switched by tower - call Departure.
Above 1500 feet AGL, complete the After Takeoff checklist.
b. Navigate the departure
Call Departure (if not already accomplished).
(2) Monitor engine instruments (EPR, Oil, EGT, RPM, etc) to ensure the engine is
within operating limits.
(3) Initiate the climb checklist (passing 10,000 feet or final level off, whichever
Continue climb checklist passing transition altitude (18,000 feet).
(5) One thousand feet prior to final level off, check outside air temperature (OAT),
give a cruise EPR, and an Indicated Mach Number (Cruise Mach).
The standards for departure include arcing to a tolerance of +1 NM and course control to a
tolerance of +2 NM and 3 radials. On departure, 90° turns are led by 1% of Ground Speed, True
Airspeed, or Indicated Airspeed, using that order of precedence. Indicated Mach Number (IMN)
is an indication of TAS; e.g. 0.5 IMN = 300 KTAS, 0.6 IMN = 360 KTAS, etc. If IAS is 250
KTS and IMN is 0.5, lead the turn by 3 DME. TAS may also be determined by adding 5 KTS
for each 1000' of altitude to the aircraft's IAS.
EXAMPLE: What is my lead turn to arc on the departure if....
= 10,000 feet MSL
= 250 KTS
