Just like to clarify something more......
You have position lights, strobe lights and anti collision lights.
POS/STROBE (Strobes are the white flickering lights in the wingtips.)
OFF - Position lights are off, and the strobes will not activate when airborne.
POS - Position lights on, but no strobes after airborne. (used on some early model MD's not having this system connected to the ground shift.
BOTH - Position lights on and strobes on after airborne.
ANTI COLLISION ( Red lights on roof and belly of the plane) So this is what the fueler talked about.
On - Lights on
Off - Lights off
So the fueler just noted that the anti collision light switch was left in the on position, meaning that the after parking checklist was not performed either.
Somone asked regarding the reduction of thrust to idle if a reverser inadvertently deploys. This is not so on an MD, hence it is a memory item checklist. It is performed by heart. All you wil see is the yellow (and blue) reverser inter(lock) lights staring you in the face. Probably accompanied with some pretty nasty yawing and banking.
