Checks done during taxi?

[boggy123]

I am reading through the Dash 1 and saw the list of items done during taxi, before takeoff. Can someone confirm that ALL of these items are done as a panel scan before every take off or are some omitted because they are done during the panel scan pre or after start?

I also read somewhere that the mnemonic SLIPER (Speedbrake/Lights/IFF/Probe heat/Ejection seat/Radar) is used pre take off. Would this be done right before line-up in addition to all the check items below or does this replace all the checks below?

TAXI
*1. Brakes and NWS-Check.
*2. Heading-Check.
*3. Flight instruments-Check for proper operation.

BEFORE TAKEOFF
*1. ALT FLAPS switch-NORM.
2. MANUAL TF FLYUP switch-ENABLE. I was told here previously that some planes do not have this opton
3. Trim-Check pitch and yaw trim centered and
roll trim as required. Refer to figure N1, page
N7.
4. C DF ENG CONT switch-PRI (guard down).
5. DR ENG CONT switch-NORM (guard down).
6. Speedbrakes-Closed.
7. Canopy-Close, lock, light off.
8. IFF-Set and check.
9. External tanks (if installed)-Verify feeding.
10. FUEL QTY SEL knob-NORM.
11. STORES CONFIG switch-As required.
*12. GND JETT ENABLE switch-As required.
*13. Harness, leads, and antig system-Check.
14. EPU-Check.
15. FLIR-As required.
16. TFR-As required.
17. PROBE HEAT switch-PROBE HEAT.
*18. Ejection safety lever-Arm (down).
*19. Flight controls-Cycle.
*20. OIL pressure-Check psi.
*21. ALOW MSL FLOOR Data-Check.
*22. All warning and caution lights-Check.
23. Adjustable sliding holder (when utility light is
not in use)- C DF Full forward, rotated cw, and
secured.
24. TGP-Stow

There’s technique involved in when different pilots accomplish all the items, but I think the most common you’d see is going through all those checks as a flow after being armed up but prior to calling ready for takeoff. The SLIPER acronym ir any variation thereof would be done rolling onto the runway to do the last steps that you don’t do until right before takeoff (like arm the seat, double check caution panel, etc).

Ok, cool. Understood. Thanks for explaining that.
