Is this to avoid transponder-less gliders or are they installing PF to
avoid collision with other bombers in close formation flying? I wonder
what sorts of testing they did.

Nothing quite so exciting, both the Vulcan and the BBMF planes fly in air
show displays, this is mostly to provide increased public tracking and also

because of the number of smaller aircraft associated with air shows.
The RAF have been quite encouraging in their support for public tracking of

their display flights.
