For operators with Honeywell Primus Elite, the PEAF (Primus Elite Advanced Features) offers upgrades to the DU-875 digital displays, replacing analog CRTs in the flight deck. These digital displays allow pilots to see more chart and graphical weather information than they could on the obsolete CRTs. Additional features include SVS (Synthetic Vision System), TCAS Overlay on Enhanced Moving Map Displays, and METAR weather reports.
The Honeywell PEEF (Primus Elite Enhanced Features) is an upgrade that replaces all pre-DU-875 displays with DU-875 displays in the flight deck.
