Overshooting a Storm

Figure 5- 38
Another example of the pilot' s importance in helping the radar serve its
safety/comfort purpose is shown in figure 5- 39. This is the blind alley
or box canyon situation. Pilots can find themselves in this situation if
they habitually fly with the radar on the short range. The short- range
returns show an obvious corridor between two areas of heavy rainfall,
but the long- range setting shows the trap. Both the near and far
weather zones could be avoided by a short- term course change of
about 45_ to the right. Always switch to long range before entering such
a corridor.
