What does it do?
Slot missed message
Sent by AO or FMP on behalf of AO when:

- When an RVR is required, as it was not in the FPL; or
- To confirm a regulation
RJT
Rerouting rejection message
How is RFI indicated in a flight list?
An I in the S column
How long is a SIP valid for?
15 minutes
What 2 messages does ETFMS need in reply to a SIP?

What are the correct responses to a RRP?

When can an REA message be sent?
From:
EOBT minus 15 minutes until up to the CTOT

What are the FAM timings for flights “departing from, within or with an elapse time of less than 3 hours to, a CPR-covered FAM enabled area?
Flights will be “shifted” up to 3 time by 5 minutes, then a further 2 minutes before being FLS. For a total of 17 minutes.
What are the FAM timings for flights “departing from non-CPR covered areas with an elapse time of more than 3 hours to a CPD-covered FAM enabled area?
Flights will be “shifted” up to 23 times for 5 minutes each time, and then suspended after another 5 minutes. For a total of 120 minutes.
How does an AO handle being FLS due to FAM?
A DLA must be sent with the new EOBT. A SAM or DES will be sent in reply.
If the flight will not operate a CNL must be sent.

FAM is applied on all flights, whether regulated or not, departing from, landing at or crossing areas where CPRs are received by the NM and FAM is activated.
