2.c. ............

Relative responses of the flight deck instruments must be measured by latency tests
or transport delay tests, and may not exceed 150 milliseconds. The instruments
must respond to abrupt input at the pilot-s
position within the allotted time, but not before the time that the helicopter or set of
helicopters respond under the same conditions
- Latency: The FTD instrument and, if applicable, the motion system and the visual
system response must not be prior to that
time when the helicopter responds and may
respond up to 150 milliseconds after that
time under the same conditions.
- Transport Delay: As an alternative to the
Latency requirement, a transport delay objective test may be used to demonstrate
that the FTD system does not exceed the
specified limit. The sponsor must measure
all the delay encountered by a step signal
migrating from the pilot-s control through all
the simulation software modules in the correct order, using a handshaking protocol, finally through the normal output interfaces
to the instrument display and, if applicable,
the motion system, and the visual system.

The intent is to verify that the FTD provides
instrument cues that are, within the stated
time delays, like the helicopter responses.
For helicopter response, acceleration in the
appropriate, corresponding rotational axis is
preferred.

3. Equipment Operation.
3.a. ............

All relevant instrument indications involved in
the simulation of the helicopter must automatically respond to control movement or
external disturbances to the simulated helicopter or set of helicopters; e.g., turbulence
or winds

3.b. ............

Navigation equipment must be installed and
operate within the tolerances applicable for
the helicopter or set of helicopters. Levels 6
and 7 must also include communication
equipment (inter-phone and air/ground) like
that in the helicopter. Level 5 only needs
that navigation equipment necessary to fly
an instrument approach

3.c. ............

Installed systems must simulate the applicable helicopter system operation both on the
ground and in flight. At least one helicopter
system must be represented. Systems must
be operative to the extent that applicable
normal, abnormal, and emergency operating procedures included in the sponsor-s
training programs can be accomplished.
Levels 6 and 7 must simulate all applicable
helicopter flight, navigation, and systems
operation. Level 5 must have functional
flight and navigational controls, displays,
and instrumentation
