7. SEC check is performed next to ensure that the engine can operate in secondary control mode.
SEC mode will be entered automatically if there is an engine damage or malfunction. The pilot thus
needs to ensure that SEC mode works correctly. Parking brakes shouldn’t be engaged, ensure that
the aircraft is on chocks and back them up with toe brakes. Lift the guard and move the ENG CONT
switch to SEC. The MASTER CAUTION light and the SEC caution light come on. The engine nozzle
closes and should indicate less than 5% on the NOZ POS indicator on the right instrument stack.
In SEC RPM might be lower than in PRI mode. Check smooth RPM operations while in SEC and
when satisfied return the ENG CONT switch to PRI and close the guard. The MASTER CAUTION and
SEC lights should go out and the nozzle open up to more than 94%.
In multiplayer you can check your wingman
’s SEC test and confirm his nozzle opening and closing.
SEC check is not mandatory to have a ready-to-go jet.
8. A good idea while in that area is to check proper speedbrake operation. Open the
speedbrake with the slider on the throttle and check the SPEED BRAKE indicator on the
left auxiliary console. Remember it takes about two seconds to open and six seconds to
close; ensure that it
’s closed before taxi.
9. The defence suite power-up starts at the TWA (THREAT WARNING AUX), located
on the left auxiliary console. Depress the lower right POWER button and the SYSTEM
POWER green light illuminates.
You can then move to the CMDS panel and power up the RWR and JMR pod with both toggle
switches to ON. The CMDS has four countermeasure banks but only the CH (chaff) and FL (flares)
are used in the Korean squadron F-16. Bank 01 and 02
are not implemented in the F-16 in Korea and as such
these two switches can remain OFF. You may need to
power them ON with other versions of the F-16.
The PRGM knob can be set to any program (preset
through DTC) you like and you should rotate the MODE
knob as desired or pre-briefed. Once all is set correctly
(assuming
you didn’t forget to move the ECM switch to
OPR earlier) the GO status indicator should come on,
telling you that all systems are ready to be deployed.
You may also power up and check the HMCS at this stage
but it’s something I personally prefer doing at FENCE in.
Moving up to the gear panel set CAT I or III according to your loadout (check the STORES CONFIG
caution light) and confirm that all three gear lights are green.
Move up to the TWP (THREAT WARNING PRIME) and
perform the BITs on the RWR suite. These tests might be
different according to the selected F-16 variant. These are
relevant to the ALR-56 RWR:
Depress the SYS TEST button and check the indication on the
RWR displays. Then check the MSL LAUNCH indicator and
AUDIO by depressing the indicator. Once satisfied the system
is running normally, depress the Handoff button. This sets the
RWR to diamond float mode.
This item is very often overlooked and if omitted will
prevent the RWR suite from warning you of threats!
