SECTION 11 SINGLE PILOT IFR SYSTEM, SFIM 85T31 A.F.C.S. Quick Reference Guide 11.1 GENERAL The SFIM Automatic Flight Control System signifi cantly reduces pilot workload allowing single pilot IFR operations on Twinstar helicopters. It combines one basic three-axis Autopilot, one Flight Director Coupler (FDC) and one Pitch and Roll Monitor.
Page 79
11.3 FLIGHT DIRECTOR COUPLER (FDC) The FDC provides fl ight path guidance: when coupled, the system will automatically sat- isfy pitch and roll commands necessary to capture and track the desired fl ight path. Selecting a fl ight director mode causes the fl ight director bars to come into view on the ADI.

11.6.3 Vertical Speed Indicator (VSI) The VSI displays the instantaneous vertical speed of the helicopter an dby means of a knob con- trolled bug allows the pilot to select the desisre vertical speed for the V/S mode. 11.6.4 Actuator Position Indicators (API) The API give an indication of series actuator extension or retraction about their mid point.

When illuminated, the green annunciators indicate that the relevant mode(s) is (are) active (one longi- tudinal mode can coexist with one lateral mode, e.g. ALT and HDG). The display is the repetitve of that one shown by the AP/CPL mode controller on which an active mode is signalled by “ON”...

• A “trim demand”. This alarm is triggered whenever a P or R series actuator is out of the center by more than 2/3 of the actuator’s stroke. This might happen in case of an inoperative auto-trim. In this event, the pilot switches off the relevant trim and recenters the corresponding API whenever the trim demand light comes on.
Page 88
• The rotating selector enables the pilot to pre-fl igh test: - The annunciators - The excessive devition warning lights - The automatic trims - The pitch and roll monitor • A small red light signals a test is in progress. 11.6.6 ACTUATOR POSITION INDICATORS The API gives an indication of series actuator extension or retraction about its mid-point.

The processed heading error signal activates the series actuator. Since there is no automatic trim in the yaw control linkage, the pilot has to refer from time to time to the yaw API. Fly-through characteristics: • In hover: To change the heading reference datum the pilot acts on the antitorqe pedals. The pedal motion detector by detecting the pilot input on the pedals, switches the yaw channel into syncronization.

When the deviation from glide-slope beam falls below a predetermined value (1/3 dot on glide de- viation scales) the FDC feeds inputs to the AP pitch channel so as to asymptotically approach the glide-slope beam. The pilot reduces power manually to avoid VNE over shooting. G/S green caption illuminates.

This warning is generated when deviation from glide-slope beam is slightly above 1 dot. 14.4.4 Auto-Level When approaching the runway, the FDC automatically levels off and automatically maintains a radio-height of 80 feet providing radio-altimeter signal is valid.
Page 104
NOTE: 1) Beep-trim and stick release are disabled as soon as G/S mode is effective 2) The pilot is not supposed to operate these commands unless safety demands 3) If during glide-slope approach the radio-altimeter signal turns invalid (actual failure or instrument test carried out by the pilot), the G/S mode is automatically disengaged.

All other coupled modes are reset except HDG, the G/A annunciator illuminates, the aircraft rolls wings level and the yaw channel maintains the heading observed at mode engagement or fl ies to the heading selected on the HSI if HDG mode is active. Once the G/A mode has been selected and all lateral modes reset (except HDG), any lateral mode can be subsequently reselected.
Page 106
SECTION 15 LATERAL MODES The FDC coupler generates roll commands to the autopilot computer. If F/D mode is punched on on the mode controller, those roll commands are displayed by the ADI vertical (roll) command bar thereby allowing the pilot to monitor the correct operation of the FDC. The engagement of any of the lateral modes freezes the roll reference at zero.

General Introduction The MALFUNCTIONS Page is used to create failure scenarios. The ability to set up and prac- tice realistic failures is one of the most powerful features in any simulation. Many of these fail- ures would be impractical, impossible, or unsafe to recreate in an actual aircraft. Yet, exposure to these same situations in a simulated environment can add invaluable experience.
1.1.1 First Group The fi rst group’s failures can be controlled as follows: 1. Freeze – the instrument maintains indications present at time of failure. No warning fl ags appear as the instrument is completely blocked. 2. Gradual – the instrument gradually changes indication, warning fl ags appear as appropriate To “Freeze”...
