Negative Climb Rate or Altitude Loss After Takeoff
These alert conditions (Figure 2-37), also known as GPWS Modes
3A and 3B are enabled between 50 and 700 ft above the runway
after takeoff or after a missed approach. The negative climb rate alert
condition is based on descent rate. The altitude loss after takeoff
alert condition is based on accumulated altitude loss in order to catch
descents that are too gradual to qualify for the negative climb rate alert
condition. The two together ensure that practically any descent after
takeoff or missed approach will trigger an alert.
