Onboard Performance Tool (Typical)
Overview
The Onboard Performance Tool (OPT) application calculates takeoff and landing
performance using a combination of pre-loaded and manually-entered data for a
specific aircraft configuration under current conditions.
The EFB administrator can activate or deactivate certain performance functions
and set preferences such as; pounds or kilograms, flap configuration and brake
settings, according to company policy and fleet management specifications.
CAUTION: The OPT application interface is configurable (keys, labels,
colors, etc.). The information presented in this section
represents a typical application and individual airline
implementation may be different.
Pre-loaded Data and Pilot Inputs
Pre-loaded data are configured, maintained and updated by the customer’s EFB
administrator. This data can include information about the following items:
• the airport; such as airport elevation, runway information, takeoff
intersections, obstacle information, etc.
• the aircraft; such as tail number, engine type and rating, flap
configurations, MEL, CDL, loading capacity, CG envelope, etc.
• NOTAM data that might affect performance; such as temporary runway
construction, runway modifications, or obstacles
• company policies; such as V1 basis, the use of lineup allowances,
contaminated runway selections
After selecting INITIALIZE FLIGHT on the EFB Main Menu page, the following
information is retrieved from the FMC by the OPT application:
• origin airport
• departure runway
• destination airport
• outside air temperature
• altimeter setting
• aircraft gross weight
Note: The altimeter value transferred to OPT is the value displayed on the on-side
PFD. In other words, if the INITIALIZE FLIGHT is selected from the
captain’s EFB, the altimeter value displayed on the captain’s PFD is
transferred to the OPT.
Any required data or selections not pre-loaded by the transfer function requires
manual entry or selection prior to any performance calculation.
