Narrative:

The TCA chart for las is confusing, and by its design can lead to inadvertent TCA penetrations. I have enclosed a copy of a report I filed about 2 yrs ago pointing out this problem, but I see on the newest edition of the chart that it has not been changed. I have also enclosed a TCA chart with the proposed improvement.
