Rotorcraft Flight Manual Supplement

Page 14 of 25 FAA APPROVED
When operating in no magnetometer or no magnetometer/no air data modes
rapid pitch or roll movements may result in temporary loss of attitude indication.
2.7 Maximum Airspeed
The airspeed markings on the G500H PFD match those on the standby indicator
regardless of operating altitude. This rotorcraft was originally equipped only
with a placard for determining maximum airspeed based on altitude; that placard
remains as the means to determine maximum airspeed.
2.8 Navigation Angle
The GDU 620 Navigation Angle can be set to either True or Magnetic on the
AUX page. The Navigation Angle defines whether the GDU 620 headings are
referenced to True or Magnetic North. The Navigation Angle set in the GDU
620 must match that which is set on the GNS navigators.
2.9 Course Pointer Auto Slewing
The G500H HSI will auto slew, i.e. automatically rotate the GPS course pointer
to the desired course defined by each GPS leg. The system will also auto slew
the VHF NAV course pointer when the CDI transitions to a LOC setting if an
ILS, LOC, LOC BC, LDA, or SDF approach is activated in the GPS/WAAS
navigator.
The VHF NAV (green) course pointer will only auto slew if the approach is
active in the navigator, the LOC frequency is loaded in the active NAV
frequency, and then the HSI source is changed to the corresponding VHF NAV
for the approach. Back Course approaches will auto slew to the reciprocal
course.
The system is not capable of automatically setting the inbound VHF NAV
course pointer if an approach is not active in the GNS Navigation System.
The pilot should always double check the inbound course pointer prior to
initiating any transition on any VHF NAV approach. Auto slewing the VHF
NAV course pointer to the correct selected course is a database dependent
function.
2.10 Helicopter Synthetic Vision Technology (HSVT)
The unaided use of the synthetic vision display for aircraft control, navigation or
obstacle/terrain/traffic avoidance, without reference to G500H primary flight
instruments and/or the aircraft standby instruments is prohibited.
