AMC 25.335(b)(1)(ii) Design Dive Speed - High speed protection
function
ED
Decision 2013/010/R
In any failure condition affecting
the high speed protection function, the conditions as defined in CS 25.335(b)(1)(ii) still remain applicable.
It implies that a specific value,
which may be different from the VD/MD value in normal
configuration, has to be associated with this failure condition for the
definition of loads related to VD/MD as well as for the
justification to CS 25.629. However, the strength and speed margin
required will depend on the probability of this failure condition, according
to the criteria of CS 25.302.
Alternatively, the operating speed
VMO/MMO may be reduced to a value that maintains a speed
margin between VMO/MMO and VD/MD
that is consistent with showing compliance with CS 25.335(b)(1)(ii) without
the benefit of the high speed protection system, provided that:
(a) Any failure of the high speed protection
system that would affect the design dive speed determination is shown to be
Remote;
(b) Failures of the system must be announced
to the pilots, and:
(c) Aeroplane flight manual instructions
should be provided that reduce the maximum operating speeds, VMO/MMO.
