Step 8h – Verify TRN RT LMT and BANK LIMIT settings during turn(s)
During an AP-commanded turn, verify that the time to complete a turn matches your
expectations given the setting for the TRN RT LMT parameter. For example, when TRN RT
LMT is set to 3º/s, a 90º turn should take about 30 seconds. If this is not the case, the bank angle
required by the target turn rate may exceed the set BANK LIMIT parameter. Ensure that during
an AP-commanded turn, the bank angle indicated on the EFIS screen does not reach the angle s
in the BANK LIM
et
