  • Page 31: Vertical Approach Mode (Requires Connection To Lpv Capable Gps)

    GPS LPV approach. This mode is only available in GPSS mode. To access this mode, the autopilot must be in GPSS mode and have zero vertical speed selected (section 5.4.1) or ALT HOLD (section 5.4.2) selected. Once ALT HOLD or zero vertical speed is selected the approach mode will automatically engage. It is displayed by sequencing GS ARM initially to GS CPLD, once the glide slope is intercepted, on the lower right of the display. Figure 5.4.5a shows the sequencing on the display. Figure 5.4.5a In the event that the GPS sends out a flagged vertical steering signal, the autopilot will display GS FLG and maintain the current altitude. Figure 5.4.5b shows the GS FLG display.

    After approximately 15 seconds the autopilot will revert back to TRK mode and hold the current track. At this time, other autopilot modes can be selected. Figure 8.1a 8.2. AEP (Automatic Envelope Protection) This mode serves as a passive protection system while the aircraft is being flown with the autopilot disengaged. AEP monitors the aircraft bank angle; if the bank angle exceeds 40°, AEP will show AEP ACTIVE on the display of the autopilot as well as use the autopilot roll servo to both nudge the aircraft back to a safe bank angle and to inform the pilot that the bank angle limit has been reached. There will also be a long, single tone sent to the buzzer (if equipped) when AEP is active. Figure 8.2a shows the AEP ACTIVE on the display. Figure 8.2a While the autopilot is disengaged, AEP is in a standby mode while monitoring the bank angle. This is indicated on the display by showing AEP STBY in the lower left area of the display.

  • Page 39: Sensor Failure Monitoring

    If a sensor fault is detected, the autopilot will disengage, flash a warning on the display, and provide three short tones to the buzzer (if equipped). Figure 8.4a shows the flashing warning sequence on the display. To clear this mode, the power must be cycled on the autopilot. It is recommended to have the autopilot inspected before returning to service if this error occurs. Figure 8.4a 8.5. Minimum and Maximum Airspeeds The autopilot includes minimum and maximum airspeed protections. This prevents the autopilot from flying the aircraft into a stall or past V If the aircraft reaches the minimum airspeed (in knots indicated airspeed) with the autopilot engaged, it will flash a warning on the display, send one long tone to the buzzer (if equipped), and lower the nose of the aircraft to maintain the minimum setting. Figure 8.5a shows the minimum airspeed display warning. Figure 8.5a Rev: B Vizion PMA Operation TruTrak Doc: 167...
