integrated Backup Flight Display (iBFD)

Pilots understand the risk of a primary flight instrument failure while flying.
In certain situations the loss of the Attitude Indicator is perhaps the greatest risk a pilot can face.

This iPhone based integrated Backup Flight Display (iBFD) is an inexpensive, easy to operate tool intended to reduce risk and improve safety if an instrument fails and no other backup is available.

This application consists of an Attitude Indicator, Heading Indicator, GPS Altimeter, Vertical Speed Indicator, GPS (Air) speed Indicator, Side Slip Indicator, and Clock.

It can also be used as Flight Data Recorder(FDR) and Cockpit Voice Recorder(CVR). This function is activated by touching the red circle in the upper left corner.
Recording is stoped by touching the red circle again or it will be stoped automatically when large G is applied.

iBFD uses the iPhone's 3 axis Gyro sensor as its primary sensor. Pitch and Roll angles are calculated using the Gyro data and the same algorithm as strap down Inertial Reference Systems (IRS), therefore it doesn’t suffer from a Singularity at pitch angle +/-90 degree.

iPhone's 3 axis Accelerometer and GPS data are used as auxiliary sensors to improve accuracy and prevent Gyro drift error accumulation, similar to the approach used in a real IRS.

The iBFD performs noticeably better than other comparable applications on the market.

Unfortunately the iBFD doesn’t have FAA certification. It doesn’t have enough reliability for use as Primary Flight Instruments, and neither our software nor your iPhone have been subjected to rigorous certification tests.

All information displayed on the iBFD is for reference only!

Therefore, we are not responsible for any death, injury or damage as a result of using the iBFD.
USE THIS DEVICE AT YOUR OWN RISK!

Nevertheless, during an In Flight Emergency having an iBFD is far better than having no instrument at all. Particularly if in a limited visibility situation with an inoperative Attitude Indicator.

Engine vibration can affect accuracy of the iBFD, so special consideration must be given to mounting the iPhone to the cockpit instrument panel or glare shield.

Other features
(1) There are three display color modes; Day, Night or NVC.

(2) Altitude/Speed is selectable in units of feet/knots, feet/MPH or meter/kilometers per hour.

(3) Airspeed is calculated using GPS Speed, Wind Direction, and Wind Velocity.
Wind Direction and Velocity are obtained via ATIS and set manually.

(4) Pitch angle zero can be adjusted manually by touching center of the display.

(5) Magnetic Heading or True Heading, and GPS or M.S.(Magnetic Sensor) are selectable.

(6) Settings Window for entering parameters and user preferences.

(7) Battery Icon indication.

(8) Recorded data can be accessed by Files.

Note :
Initial roll and pitch angle are calculated using the accelerometer at the time of alignment (same as real IRS).
Therefore, if acceleration due to motion is applied during alignment, an angle error will occur.
However, such initial angle error automatically decreases with time and disappears after a few minutes in case of level flight.
