Figure 9.49.3 shows two figures which illustrate the NCR alerting parameters as
defined by TSO-C151b.
The NCR alert is issued when the altitude loss and height are within the range in the
first figure, or when the sink rate (negative vertical speed) and height are within the
range in the second figure.
