Roger,

I'm trying to find the regulation you reference. 91.209 requires
operation of position lights at night but not anticollision lights.
91.209(b) calls for operation of anticollision lights unless the PIC
"determines that, because of operating conditions, it would be in the
interest of safety to turn the lights off."

I may have missed a reg that requires operation of anti-collision
lights, but I've missed stuff before and will again.

A number of aircraft POH's and placards state that the strobes should
not be operated on the ground, in fog or in cloud. Because of the
potential to destroy the night vision of others who may be in the area
(a safety issue), I have always taught that strobes should be turned
on on taking the runway and off on exiting the runway. While it is a
personal preference on the part of the pilot, I've felt that safety
dictates that they be left off when on the ground (even if the a/c has
no beacon) due to the potential for danger to others. (Or distraction
as others comment on the guy who taxies with his strobes on during the
day and promptly walk into the open manhole in the ramp g.)

All the best,
Rick

Strobes on the ground, unless you're taxiing onto the active for
takeoff, or just landed, are very annoying. Rather than having to keep
track of yet one more thing, I prefer to simplify my workload by
leaving them off on the ground until the tower clears me to taxi onto

I can't do that. Regulations require they be on as soon as I start the
engine. (any time the prop is turning)

the active runway. Upon landing, I turn the strobes off after exiting
the runway, along with everything else on the post-landing checklist.

My HO, your mileage may vary, etc.
