Honeywell Bendix/King KFD 840 Primary Flight Display • • • • CG envelope in weight and arm Empty aircraft weight Empty aircraft arm Empty weigh date (Date the aircraft was weighed) The aircraft units of measurement are one of the following selections: • Inches, pounds and gallons • Feet, pounds, and gallons • Centimeters, kilograms and liters • Meters, kilograms and liters The display does not accommodate CG envelopes in percent (%) Mean Aerodynamic Cord (MAC), moment, or non-linear envelopes.
Honeywell Bendix/King KFD 840 Primary Flight Display The aircraft configuration information from the PC Utility is transferred and stored on an SD card that is loaded into the KFD 840. The SD card must be installed in the KFD 840 whenever the Weight & Balance function is to be used. The SD card can be formatted as FAT or FAT32. The card size must be a minimum of 128 MB and a maximum of 16 GB when used for Weight and Balance.

Press “RETURN” to return to the flight display. If a file is invalid after an attempt to read it, an error is displayed: “ERROR: file cannot be read. Select another file to load or press RETURN to exit”. Once a file is loaded, the Weight and Balance page displays.
Honeywell Bendix/King KFD 840 Primary Flight Display WEIGHT AND BALANCE PAGE The Weight and Balance page displays an image of a plane with a place to enter each seat weight, baggage weight and fuel quantity. A graph of the calculated CG envelope and current computed CG data table is displayed. The pilot should verify the displayed data is correct and current for the aircraft.
Honeywell Bendix/King KFD 840 Primary Flight Display • ENV button - Press the ENV button to display a popup menu to toggle the CG envelope data point (WEIGHT, ARM) ON or OFF. The WEIGHT and ARM values that define the envelope are displayed in a table next to the graph. This allows the pilot to verify the displayed envelope matches the airplane limitations. The ARMs of the seats, baggage compartments, and fuel tanks are also displayed in the aircraft picture.
Honeywell Bendix/King KFD 840 Primary Flight Display Turn the right knob to set the highlighted value. Press SELECT to accept the input value and toggle to the next location. When a seat is selected, the first turn of the knob sets the value to 170 lbs or 77 kgs. Subsequent knob turns for seats increment in 5 lb or 1 kg steps. Baggage weights start at 0 and increment in 5 lb or 1 kg steps.
Honeywell Bendix/King KFD 840 Primary Flight Display on the CG plot. If the zero fuel weight limit has been defined for the aircraft and the calculated ZERO FUEL WEIGHT exceeds the limit or the current ZERO FUEL ARM exceeds the CG envelope, the appropriate data value and symbol are displayed in red text and a red “EXCEED” message is displayed below the table. As fuel is added (in volume, gallons, or liters), its weight is calculated (based on the Fuel Density) and added to the ZERO FUEL WEIGHT and ARM.

MISCELLANEOUS DATA AREA WIND, GROUND SPEED, TRUE AIRSPEED, AND OUTSIDE AIR TEMPERATURE The wind, cross wind (XW) and Head wind (HW), ground speed (GS), true airspeed (TAS), and outside air temperature (OAT) labels are located on the left side of the HSI. Wind The wind display consists of a digital readout for wind speed in knots and arrows for direction. The wind information is only available from GPS1 and it must be a digital GPS.
Honeywell Bendix/King KFD 840 Primary Flight Display if available, and then calculate the True airspeed. The wind values can then be calculated based upon the most accurate true airspeed. Ground Speed Ground Speed, GS, is displayed in the lower left portion of the PFD in knots/miles per hour, with a resolution of 1 kt/mph. Speeds between 00 and 999 kts/mph are displayed in white with a trailing gray KTS or MPH label. If the ground speed data is invalid, the ground speed digits are removed.

Honeywell Bendix/King KFD 840 Primary Flight Display ADC health is determined by internally monitoring the voltage levels of the ADC throughout flight. This monitor does not detect or display failures for blocked pitot/static port(s). Symptoms of a blockage of the Pitot/Static system would manifest themselves in a manner similar to a traditional Pitot/Static system.
Honeywell Bendix/King KFD 840 Primary Flight Display HDG (HEADING) FAIL, CRM FAILURE (COMPASS REMOTE MAGNETOMETER) A “HDG FAIL” message indicates that the CRM500, Compass Remote Magnetometer, has either failed or lost communication with the KFD 840. Loss of communication or internal failure will remove all heading data from the display; however it will not have any impact on the pitch or roll attitude display. The pilot must fly using the standby instruments when the magnetometer has failed.
Honeywell Bendix/King KFD 840 Primary Flight Display IN-FLIGHT RESTART The KFD 840 is capable of a partial reset in-flight under emergency conditions. If a power failure occurs or an emergency condition occurs that warrants the need to reset the system, the pilot should maintain straight and level flight until the alignment is completed or as long as possible without compromising the safety of the flight. If an internal fault is detected, the unit may automatically attempt a reset.
