7 1.3 Communication and Navigation METRO AVIATION, INC. FMS 135M Combined navigation and communications system The Garmin GNS-430/530 system consists of two fully integrated, panel mounted nav/com radios. The system consists of a GPS antenna, GPS Receiver, GPS navigation computer, VHF VOR/LOC/GS antenna, VOR/ILS/GS receiver, VHF COMM antenna and a VHF communications transceiver. Com #1 frequencies may be transferred between standby and active via a dedicated switch on the pilot s cyclic control grip (reference paragraph 1.2.3). Holding this switch down for 2 seconds or more will place the emergency frequency in the active com 1 window. NOTE: To go back to normal operation, after a Com not Responding message occurs, the radio must be cycled off then on. Provided the GPS receiver is receiving adequate usable signals, it has been demonstrated capable of and has been shown to meet the accuracy specifications for VFR/IFR enroute, terminal, and non-precision instrument approaches. Number 1 GNS-430/530 VOR/ILS also drives the GI-106 A standby VOR/ILS Indicator directly. If the optional NR3320 VOR/ILS system is installed see for GI-106A description Standby VOR / ILS System (Optional) Standby VOR / ILS System consists of a dedicated Navigation Receiver (NR-3320) which Navigation Indicator (GA-106A) powered on the Emergency Battery Bus for VOR and LOC/ILS Navigation only. 1.4 Bus structure Emergency Battery Bus The following components are available following electrical system failure and power is ensured for a minimum of 30 minutes: Standby Horizon Cockpit Floodlight Standby VOR / ILS System (Optional) Essential buses The following systems are available following dual generator system failure: Both Nav / Com radios Pitch and Roll SAS Yaw SAS Mode S transponder 7

The remaining system software versions can be verified on the AUX group sub-page 2, SOFTWARE/DATABASE VER GPS navigation limitations Enroute IFR enroute and terminal navigation predicated upon the GPS receiver is prohibited unless the pilot verifies the currency of the data base or verifies each selected waypoint for accuracy by reference to current approved data. 10

11 Approach Instrument approach navigation predicated upon the GPS receiver must be accomplished in accordance with approved instrument approach procedures that are retrieved from the GPS equipment database. The GPS equipment database must incorporate the current update cycle. Instrument approaches utilizing the GPS receiver must be conducted in the approach mode and Receiver Autonomous Integrity Monitoring (RAIM) must be available at the Final Approach Fix. Accomplishment of ILS, LOC, LOC-BC, LDA, SDF, MLS or any other type of approach not approved for GPS overlay is not authorized. Use of the VOR/ILS receiver to fly approaches not approved for GPS require VOR/ILS navigation data to be present on the ND. When an alternate airport is required, it must be served by an approach based on other than GPS or Loran-C navigation, the aircraft must have the operational equipment capable of using that navigation aid, and the required navigation aid must be operational. VNAV information may be utilized for advisory information only. Use of VNAV information for Instrument Approach Procedures does not guarantee Step-Down Fix altitude protection, or arrival at approach minimums in normal position to land GNS-430/530 Setup requirements If not previously defined, the following default settings must be made in the SETUP 1 menu of the GNS-430/530 prior to operation (refer to Pilot's Guide for procedure if necessary): dis, spd kt (sets navigation units to nautical miles and knots ) alt, vs ft fpm (sets altitude units to feet and feet per minute ) map datum WGS 84 (sets map datum to WGS-84, see note below) posn deg-min (sets navigation grid units to decimal minutes) NOTE In some areas outside the United States, datums other than WGS-84 or NAD-83 may be used. If the GNS-430/530 is authorized for use by the appropriate Airworthiness authority, the required geodetic datum must be set in the GNS- 430/530 prior to its use for navigation. 11

NOTE: In event of a loss of both GNS-430/530 units, holding the com #1 freq transfer switch on the pilot s cyclic on for 2 seconds or more will place in the #1 Com for emergency communications Navigation If navigation information is not available or invalid, utilize remaining operational navigation equipment as required. If "RAIM POSITION WARNING" message is displayed the system will flag and no longer provide GPS based navigational guidance. The crew should revert to the VOR/ILS receiver or an alternate means of navigation other than the GPS receiver. If "RAIM IS NOT AVAILABLE" message is displayed in the enroute, terminal, or initial approach phase of flight, continue to navigate using the GPS or revert to an alternate means of navigation. When continuing to use GPS navigation, position must be verified every 15 minutes using VOR/ILS receiver or another IFR-approved navigation system. 18

19 If "RAIM IS NOT AVAILABLE" message is displayed while on the final approach segment, GPS based navigation will continue for up to 5 minutes with approach CDI sensitivity (0.3 nautical mile). After 5 minutes the system will flag and no longer provide course guidance with approach sensitivity. Missed approach course guidance may still be available with 1 nautical mile CDI sensitivity by executing the missed approach. In the event of a dual GNS-430/530 System failure that can t be reset by cycling power to units navigation is to be accomplished with the Standby VOR/ILS System. If emergency communications is not available proceed using standard loss of communications procedures. 19

25 4.4 IFR operation NOTE Flights into extreme turbulence (e.g. thick building clouds) should be avoided or conducted with appropriate precaution. When operating near the extremes of the flight envelope or in turbulence, reducing airspeed by 10 to 15 kt may reduce pilot s workload. To reduce the potential for vertigo effects when flying in clouds, it is recommended that the strobe lights are switched off. 4.5 Approach under IMC Recommended instrument approach speed kt 4.6 AFCS operation When selecting the upper modes of the AFCS, the selection is identified by an ON, A (armed for capture), or C (Capture) caption on the appropriate select button on the APMS panel. Annunciation of the selected mode is also presented in the primary flight display (PFD). Arming of a selected mode is displayed on the PFD as a blue caption that turns to green upon capture. Only one pitch-axis and one roll-axis mode may be active at the same time. When a second mode in an axis is selected, the first is cancelled. However, for those modes which have arm / capture functions, the first mode will remain on when the armed mode of the second is active; when the armed mode changes to capture, the first mode is cancelled. Before liftoff, ensure that the AFCS is on and A.TRIM has not been de-selected. TRIM REL switch on cyclic - Press and hold during liftoff Maneuver to desired attitude and release. NOTE It is possible to modify the pitch and/or roll attitude by use of the lower 4-way switch (ATT TRIM) on the cyclic grip whenever an upper mode in the specific axis is not engaged. The attitude beep function is disabled in the axis or axes in which an upper mode is active. However, this switch does function to modify the selected value when the modes of HDG, IAS, VS, and ALT are engaged. With the HDG, IAS, VS or the ALT mode(s) selected the respective reference values will be marked with green triangles on the PFD. To make changes of the reference values, the ATT TRIM switch may be used to modify the selected value. The HDG button on the AFCS control panel may also be used for heading changes. 25

26 Climb at or above 60 knots IAS - Pitch axis use attitude hold, IAS, or VS. - Roll axis use attitude hold, HDG or NAV. NOTE All upper modes are inhibited at indicated airspeeds less than 60 knots except IAS which may used at 40 knots and above Attitude hold/attitude beep - Maneuver the helicopter to desired attitude and release trim release button. - Pitch and roll attitude may be modified by longitudinal and lateral action on 4-way trim switch on cyclic grips.
