Mode 6 provides the following advisory alerts: transition through approach minimums, altitude callouts on approach and excessive bank angles.
-Transition through the preset approach minimums, (APPROACHING DECISION HEIGHT or APPROACHING MINIMUMS), generates an aural “MINIMUMS, MINIMUMS” warning. The warning function is enabled between 1000 feet and 10 feet radio altitude or DH minimums and when the corrected altitude exceeds the MDA value by 200 feet. The landing gear must be down for activation of the warning.
-An altitude callout function generates annunciation for descent below predetermined altitudes. The aural “ONE HUNDRED”, “FIFTY” and “THIRTY” indicates the transition through 100, 50, and 30 feet AGL. The last annun-ciated or transition altitude is memorized. This will prevent the repeat annunciation of a callout, should the air-plane transition through said altitudes again. The memory is cleared and reset, once the airplane climbs to an altitude greater than 1000 feet, or if a transition occurs from approach mode to takeoff mode. A “smart altitude callout” provides an aural “FIVE HUNDRED” at 500 feet radio altitude during a non-precision approach. The callout is generated during a precision approach if the airplane flight path deviates greater than ±2 dots of either the glideslope or localizer. The callout is also generated during a backcourse approach.

MODE 6 — Altitude Callouts (Cont)
-The excessive bank angle alert is a function of the roll angle with respect to altitude above ground level. The alert envelope varies linearly from a 10° bank at 30 feet AGL, at 40° of bank at 150 feet AGL, to 55° of bank at 2450 feet AGL. This will generate an aural “BANK ANGLE, BANK ANGLE”. The alert is annunciated once and will repeat if the bank angle increases by 20%. The alert will be annunciated continuously if the bank angle is increased to 55°. The alert will be annunciated until the bank angle is decreased below said value.

MODE 7 — Windshear Warning
Mode 7 provides alerts and warnings when significant windshear is detected by the TAWS. Mode 7 is active during takeoff and landings phase of flight only, between 10 and 1500 feet AGL. There are two types of windshear warnings: increasing performance (updraft/headwind) and decreasing performance (downdraft/tailwind).
-For an increasing performance shear (updraft/headwind), the flight director display is removed from the display, an increasing performance shear WINDSHEAR (W) flashes for 5 seconds, then remains steady. An aural tone, “WINDSHEAR WINDSHEAR” warning is activated.
