Hazard Awareness
190-02327-03 Rev. C Pilot’s Guide 5-107
1
Alerting inhibited <200 ft AGL within 0.5 nm of approach runway or <125 ft AGL within 1.0 nm of
runway threshold.
2
Alerting inhibited within 0.5 nm of approach runway or <125 ft AGL within 1.0 nm of runway threshold.
Alerting thresholds for final descent are based on current position, speed, and flight path data.
3
Alerting inhibited within 5 nm of nearest airport, except when FLTA is not available. In such cases,
“TAWS N/A” or “ TAWS FAIL ” annunciates and ECR alerting remains active until landing.
ALERT TYPE CONDITION
Imminent Impact 1
Aircraft reaches the minimum clearance altitude of any
obstacle (IOI), terrain (ITI), or power line (ILI) in the
projected flight path.
Reduced
Clearance 1
Aircraft’s vertical flight path is projected to be within the
minimum clearance altitude of an obstacle (ROC), terrain
(RTC), or power line (RLC).
Premature
Descent 2
Aircraft is significantly below the normal approach path
for the nearest runway.
•
Altitude is <700 ft above terrain
•
Distance from destination airport is 15 nm or less
Excessive
Descent Rate
Aircraft descends toward terrain at an excessive rate.
Excessive
Closure Rate 3
Aircraft closes upon terrain at a rate excessive for gear
and flaps in the landing configuration.
Negative Climb
Rate
Aircraft loses altitude following takeoff.
•
Altitude is <700 ft above terrain
•
Distance from departure airport is 2 nm or less
•
Deviation from departure heading is <110º
Flight Into Terrain
Aircraft is too low with respect to terrain. Based on
landing gear status, flap position, and ground speed.
Excessive Below
Glideslope or
Glidepath
Deviation
Aircraft is significantly below the glidepath for the
selected approach.
Active only after departure and when the following
conditions are met.
•
Altitude is <1,000 ft AGL
•
Gear is configured for landing
•
ILS, LPV, LNAV/VNAV, or LNAV+V approach is active
and the unit is indicating vertical navigation
