Definition
A NOTAM contraction used to indicate that one item, facility, procedure, or piece of information is being substituted for another. It signals that the previous version is no longer in effect and the new content takes its place.
Plain English
A short way of saying 'replace' in NOTAMs. It means the old thing is out and the new thing is in.
Context Anchor
Seen in pilot notices called NOTAMs and other shortened aviation text where space is limited.
Derivation
RPLC is made by shortening replace, mainly by leaving out vowels. This helps you recognize it as the compact notice form of the normal word replace.
Why Pilots Care
When briefing a flight, recognising RPLC tells the pilot that something has been swapped out — an approach chart, a frequency, a procedure — and the older information should not be used.
Intuition Check
Do not read RPLC as just “repair” or “check.” In this context it means one thing is being removed and another is taking its place.
Example Sentence 1
The NOTAM read 'RPLC ILS RWY 27 WITH LOC RWY 27,' meaning the ILS approach was replaced by a localizer-only approach.
Example Sentence 2
RPLC the expired sectional chart before the next flight.
