Procedure; Aircraft; Company Policy; Manuals
This aircraft had 7 MEL [deferrals]. Maintenance cleared two items just before pushback. They did not work. Number 2 EFB failed during performance briefing. Weather Radar failed during pre-flight test. PDM procedures followed for EFB. First Officer had to retrieve the paper KIT for his charts. I waited until he was completely comfortable with his paper charts. The EFB failed due [to] new program [we used]; and I had to use my EFB for the performance briefing. We did not have a performance computer. The 7 MEL's required extra review; and then Maintenance cleared two; but did not work; which required more time to document. Total time used prior to pushback was 27 minute primarily due to failure of Number 2 EFB. One MEL; the HUD INOP; actually worked fine. Also the EFIS worked; ops normal. This was requested by Maintenance to see if they worked; before any more maintenance.More proactive maintenance. Why does an aircraft have 7 MEL's? The EFB product is not reliable. It freezes up the EFB screen; and frequently shows software errors. The touch screen is sometimes not compatible with the software. It does not 'touch' easily.
An MD-11 was delayed for a variety of reasons including an inoperative EFB; Weather Radar failure; HUD inoperative; and then a review of seven MEL deferrals for complete understanding.
