It is nearly 200 pages. These are the recommendations from the Executive Summary as a taster.
Recommendations
a)Introduction of the IFR dynamic stability requirements as a general requirement for
all operations, including VFR.
b) Introduction of appropriate requirements (or guidance) on criteria for DVE
operations based on consideration, but not full adoption, of all IFR requirements
for:
i) night operations; and
ii) operations in visual ranges of less than a ‘specified’ minima, which takes
account of permitted aircraft height and associated view over the nose. Look
down angles associated with heights of greater than 1000 ft (i.e. greater than
15-20 deg) would impose severe restrictions on the available visual cues.
c) Introduction of specific requirements (or guidance) on criteria for FCMCs.
d) Introduction of a requirement for an attitude indicator flight instrument for all
operations, including VFR.
e) Specification and adoption of FODCOM training requirements for all civil helicopter
operations that fall into the DVE category specified at b) above.
f) Raise pilot awareness of the problems associated with operations in the DVE, i.e.
the interaction between vehicle handling qualities and visual cueing conditions.
g) Reduce the probability of pilots encountering DVE conditions by providing
guidance on whether to fly or not in marginal conditions with the potential for DVE
encounters. This could be achieved using a simple probability index based on
consideration of those factors that contribute to a high accident risk scenario,
including:
i) meteorological conditions (precipitation, cloud base etc.),
ii) visual conditions (time of day, fog/mist/haze conditions, visual range, acuity of
the visual horizon etc.),
iii) aircraft configuration (navigation aids, flight instruments, pilot FOV and layout
etc.),
iv) aircraft handling qualities (SAS, FCMCs).
h) Image analysis using the techniques presented in this report should be
investigated as a means of supporting the pilot training in g), using digital images
of typical operating conditions and UCEs.
DVE - Degraded Visual Environment
UCE - Usable Cue Environment
The first recommendation would put the cat amongst the pigeons!
In fairness it is a reasearch paper, but someone needs to have regard to its practicality!
Some of the other ideas are thought provoking on the briefest of reads.
