ALOW

The Altitude LOW (ALOW) page allows you (no pun intended) to set low altitude advisory settings. Here is a quick summary of how the system works.

1. Make sure CNI (Communication, Navigation & Identification) DED page is displayed, which can be selected by pressing Dobber Switch LEFT (RTN).

2. RDR ALT (Radar Altimeter) switch should be set to ON (FWD) for the ALOW system to be active.

3. Select ALOW page by pressing ALOW (2) button on the ICP (Integrated Control Panel)

4. Altitude restrictions can be on the steerpoint of your choice, which can be selected with the DED Increment/Decrement Switch.

5. CARA ALOW (Combined Altitude Radar Altimeter Altitude Low) is used as a warning setting for low altitude flying. When below this altitude setting, the “AL” notation flashes and VMS (Voice Message System) gives an aural “ALTITUDE” call.

6. MSL FLOOR is your Minimum Safe Level Floor, and is used as a warning setting for approaches. A MSL FLOOR of 18,000 ft is generally used as a reminder when flying below Transition Altitude, which is the altitude below which the pilot needs the switch to local barometric pressure setting (QNH) for the altimeter calibration setup. The MSL FLOOR can be set at any altitude of your choice, and descending below this al titude will trigger a VMS (Voice Message System) aural “ALTITUDE” call.

7. CARA ALOW or MSL FLOOR settings can be modified by selecting their data field with the Dobber Switch UP/DOWN (asterisks indicate which field is selected), then entering the desired value on the ICP keypad, then pressing ENTR button.
