>Out of interest, how many of you notice the strobes on GA aircraft in average day conditions?<
I usually see the landing light before I see the strobes. On most GA aircraft the latter aren't particularly bright. Military HISLs are a lot easier to see and I almost always pick up the local Griffins and Squirrels initially via their strobes.
Perhaps I'm turning into a Grumpy Old Man but my pet peeve is people who seem to feel that the strobes should go on as soon as the engine starts and go off when it stops. Distracting during the day if you're parked next to them, and just the thing for wrecking your night vision in a millisecond.
