Narrative:

I am in the efb test program using the ipad instead of paper charts. When I selected a chart that expired that day; I got a red flag; warning me the chart had expired. Since we were after midnight zulu; I thought I needed to use the next chart. I convinced my first officer we should also changeover the FMC database. We had been cleared through pre departure clearance via ACARS to fly the coast 5 departure; but we failed to notice the numbering difference and loaded and briefed the coast 6. Because both the charts and FMC were changed; we did not detect any errors during the route briefing. The coast 6 departure is significantly different from the coast 5; so when we flew the coast 6 with LNAV; we deviated from the coast 5 routing. Center asked us about our routing and reassigned us the specific route points to fly.we made two errors: 1) we used charts and the FMC database too early (the changeover time is 0900Z; not 0000Z; as specified in the aom); and 2) we failed to detect the numbering change of the assigned SID (coast 5 versus coast 6). Prevention: 1) all 'effective' and 'expired' dates should include the 0900Z time on both paper and electronic charts. 2) efb training should include a lesson on the red flag warnings; and remind students of the 0900Z standard changeover time. 3) crews must brief the name and number of the cleared departure or approach procedure.

Title: B737 Captain reports changing to new charts in his EFB before the official change over time (0900Z); then changing the FMC database to match. A track deviation occurs when the Coast 6 departure is flown instead of the cleared Coast 5.

Narrative: I am in the EFB test program using the iPad instead of paper charts. When I selected a chart that expired that day; I got a red flag; warning me the chart had expired. Since we were after midnight Zulu; I thought I needed to use the next chart. I convinced my First Officer we should also changeover the FMC database. We had been cleared through PDC via ACARS to fly the COAST 5 Departure; but we failed to notice the numbering difference and loaded and briefed the COAST 6. Because both the charts and FMC were changed; we did not detect any errors during the route briefing. The COAST 6 Departure is significantly different from the COAST 5; so when we flew the COAST 6 with LNAV; we deviated from the COAST 5 routing. Center asked us about our routing and reassigned us the specific route points to fly.We made two errors: 1) we used charts and the FMC database too early (the changeover time is 0900Z; not 0000Z; as specified in the AOM); and 2) we failed to detect the numbering change of the assigned SID (COAST 5 versus COAST 6). Prevention: 1) All 'effective' and 'expired' dates should include the 0900Z time on both paper and electronic charts. 2) EFB training should include a lesson on the red flag warnings; and remind students of the 0900Z standard changeover time. 3) Crews must brief the name and NUMBER of the cleared departure or approach procedure.
