Designed along more conventional lines than the P.V.5,
the P.V.5a was an equi-span single-bay biplane with
cable bracing, sharing with the former type only the
fuselage, tail surfaces and armament. The pontoon-type
floats were supplanted by Linton Hope floats, the
internal accommodation for a bomb load was eliminated
and a 200hp Hispano-Suiza engine was fitted.
Work on the P.V.5 and 5a was initiated in parallel, but
work on the latter was discontinued early in 1917, and
only reinstated after the P.V.5 had flown, the P.V.5a
commencing flight test in the spring of 1918. It proved
inferior to the P.V.5 in terms of manoeuvrability and
pilot's view, but was satisfactory in most other respects.
Development was discontinued after completion
of flight testing as no service requirement for this
category of aircraft existed.
