PMU STATUS caution in flight indicates a fault in either of, or a mismatch between,
the weight on-wheels switches, and serves to notify the pilot that the PMU will not
revert to ground mode upon landing. This means that idle N1 will not shift from
flight idle to ground idle upon landing, and landing distance may be slightly longer
than normal.
CAUTION
Starts are not recommended with the PMU in the manual mode. However, if a
start is performed with the PMU OFF, the pilot must exercise caution in
performing the procedure to avoid a hot start.
