EICAS Ref
Read full descriptionHide full description
EICAS Reference is a study and training companion for pilots of EICAS-equipped Boeing aircraft: the 747, 757, 767, 777 and 787. It turns your own FCOM, QRH FCTM, MEL and CDL into one searchable, cross-referenced library, so you can prepare for simulator sessions, type rating, recurrent training and checkrides faster and with more confidence. MANUALS Your manuals stay yours. EICAS Reference reads them on your own devices only. Nothing is uploaded or shared, and no one else can see them. If you keep them in iCloud Drive or Dropbox, they stay in your own storage. ONE APP, FOUR BOEING TYPES (EICAS Driven Boeing) The 747, 757, 767, 777 and 787 share the same EICAS crew alerting philosophy, and EICAS Reference is built around it. Import the manuals for the type you fly, and the app builds a library that matches your aircraft and your operator. START WITH AN EICAS MESSAGE Search any EICAS message and see everything connected to it in one place: the non-normal checklist, the system description, FCTM, MEL and CDL references, and in-flight performance data. Studying a failure scenario no longer means juggling several manuals. BUILT FOR SIM AND TEST PREPARATION. β’ Review non-normal procedures by system before a sim session β’ Practise normal checklist flows with an interactive checklist built from your own QRH β’ Brush up on systems knowledge for oral exams and technical quizzes β’ Explore unannunciated items, grouped by system β’ Work through non-normal configuration landing distance tables for performance questions YOUR MANUALS, YOUR LIBRARY EICAS Reference contains no aircraft manual content. You import the manuals you are already authorised to hold, and the app builds your personal library from them. Your library reflects your own aircraft type and operator procedures, and nobody else's. β’ Import FCOM, QRH, FCTM MEL and CDL as PDFs, individually or from a folder β’ Update your library whenever a new revision is issued β’ Sync across your own iPhone, iPad and Mac β’ The original manual page is always one tap away Your manuals stay yours: they are read on your own devices only, never uploaded or shared. If you keep them in iCloud Drive or Dropbox, they stay in your own storage. ACCURACY SAFEGUARDS Performance tables are checked against the source page before they are shown. If a table can't be verified, the app shows the original manual page instead. It always shows which manual the data came from. BY A PILOT, FOR PILOTS Designed by an active, type-rated Boeing pilot who wanted a better and easier way to study. IMPORTANT EICAS Reference is a personal study and training aid. It is not an approved Electronic Flight Bag (EFB) application. It must not be used for flight operations or in-flight decision making, or in place of your operator's approved documentation and procedures. Always follow your current approved manuals and company procedures. EICAS Reference is an independent app. It is not affiliated with, endorsed by or sponsored by The Boeing Company or any airline. Boeing, 747, 757, 767, 777, 787 and related marks are trademarks of The Boeing Company.
