Q3 - Strobes at night
Maybe not such an easy one....
Take your humble PA28/C152 - maybe even small twin....decide to go night flying.
Enter aircraft and turn on the switch that you know operates the tail fin anti-collision beacon - it works.....but, on every flash of the tail fin, the wing tips explode in a cloud of dazzling white light.
You have no choice - if you want the anti-coll to work - you have to have wing tip strobes going as well.
Taxi with them on - or off?? - and what do your local regulations say about the use of anti-coll lights on an aircraft operating at night - for hire or reward.
