Description

Back up Flight Instrument for real pilot.
It works without any additional equipment.
This also functions as Flight Data Recorder(FDR) and Cockpit Voice Recorder(CVR).

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, Altimeter, Vertical Speed Indicator, speed Indicator, Side Slip Indicator, and Clock.
Furthermore, in the portrait mode of the iPad, a Map is displayed below the Attitude Indicator, and when you enter an airport code such as KFTW, the direction and distance to the airport are displayed.

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 stopped by touching the red circle again or it will be stopped 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).

GPS and Accelerometer are used with Kalman filter as sensor fusion to prevent gyro drift and improve Accuracy.

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.
And the accuracy of Map and Airport Information is not guaranteed.

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 or slider setting.

(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.

(9) Magnetic Heading can be adjusted with the slider.

(10) Function to correct roll angle. However, when performing this function, the iPhone needs to be correctly placed horizontally.

(11) Local time or UTC is selectable.

(12) GPS Altimeter and Barometric Altimeter.

(13) Roll indication by Sky pointer and Ground pointer.

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.

meh ... could be better

The roll and pitch zero-adjust should be a single tap/button, like a “cage” button. And as another reviewer commented, the app should be able to access the iPhone’s camera.

Likewise, dampening the pitch and roll sensitivity should be “single-tap” because the idea is (I suppose) for pilots to use the app with their phones mounted in moving aircraft. Pilots don’t have time to fiddle with deeply embedded settings and nested menus.

Pilots have a myriad of other things going on in the cockpit and shouldn’t have to think about (distracted by?) setting the app.

In all, the idea is great, but it’s execution is poor —which makes its functionality useless. The design must be more of an aid, and not a distraction.

Not worth 1/2 the price

Not that accurate, especially when detecting roll as the AI tends to stick in a 10 degree bank, even if I haven't rolled. It's ok for messing around but the reason for the low rating is that it doesn't override the screen saver setting so if I forget to touch the screen periodically it goes off. Supplying constant power doesn't help. That makes it useless. I'm not about to change my phone settings every time I want to use the app. I'm sorry I blew my money on this.

Great but could be better!!!

Love this app!!! One thing it needs, though, a Camera mode with the ability to adjust the zoom factor by pinching and squeezing/stretching the screen. Another thing would be a blank background for use with an apple iPhone HDMI adapter. Will give 5 Stars and recommend to ALL my friends (and YouTube Subscribers) if you add these features in the next update. Then, it will be PERFECT!!!!!
