and has, with modifications from time to time,
notably in the substitution of new engines
when they became available, been in constant
and extensive use ever since, and is still one
of the best machines in the world for its
particular purpose. The " Trainer " is, so
to speak, the modern equivalent of the
famous 504, in that it bears the same relation
to modern military types of aircraft as did
the 504 to the military types of aircraft
some 10 years ago. Consequently the
" Trainer " can be used for the complete
instruction of pilots without the need for
advanced training on other types. When
required for training seaplane pilots the
machine can be fitted with a float undercarriage.
