FANS REPORT: MAINTAINING
When an uplink instruction includes a REPORT MAINTAINING element, if the aircrew response is
WILCO, Envoy constructs a response message and automatically queues a report that has an
event trigger of +/-130 ft outside the specified flight level for 30 seconds.
Aircrew has the option to set the report to MANUAL before pressing WILCO.
