aviation, in all its forms, combines emotion and
technical excellence like almost no other mode of
transport. It’s not just pilots who have always
demonstrated their connection to flying by wearing
a special timepiece – the pilot’s watch.
In the early days of aviation, the pilot’s watch was
one of the primary navigation instruments
alongside the aviation map and a compass.
Charles lindberg would rather have gone without a
radio than a second timepiece on his legendary
transatlantic flight. to this day, most flight
procedures in instrument flying carry a
corresponding time stamp.
“pilot’s watch” is however not a protected term. It is
often used for purely design-oriented models, which
hardly do justice to the technical requirements for a
flight instrument. It was therefore natural for the
department of aeronautics and astronautics at the
aachen university of applied sciences, as one of
the leading educational and research facilities for
aviation, to take on the development of a test
standard based on the official certification
procedure for general aviation. a considerable
