Chart is used to analyze flight recording runs that have been generated by Flight. Up to two runs may be analyzed simultaneously.

For the sake of simplicity, we name the runs being analyzed as Run A and Run B; the data for each may be from two different runs or from the same run. The latter is how you can analyze two different laps from the same run. Run A is displayed in red and Run B is displayed in cyan.

The screen below shows Run A set to run Mitch001 and Run B is set to run Mitch000 (both are pre-installed example runs). The top portion of the screen shows the QView™ graph for Run A on the left and Run B on the right.

Below the QView™ graphs is a section that displays the run name, lap and segment information; Run A is on top and Run B is below.

The four graphs at the bottom of the screen display the track map, vehicle speed, lateral G force and longitudinal, or acceleration/deceleration, G force. The X axis of the three data graphs is time since data recording began for each run.

The current position in time is at the center of each graph and the actual time offset from the beginning of the run is displayed next to each run's name in the central part of the screen.

The time scale of the graphs is displayed in the lower left corner of the screen. In the example below, each graph is showing from -20s to +20s relative to the current time at the center of each graph; in other words, from 20s in the past to 20s in the future. Tap on the time scale indicator to adjust it.

Touch Interactions

• Single Tap anywhere other than a button shows and hides the toolbars
  
  
  
  
• Double Tap on any of the lower graphs enlarges the tapped graph and hides the other 3 graphs
  
  
  
  
• Double Tap on an enlarged graph reduces its size to 1/4 size and displays the 3 other hidden graphs
  
  
• Sliding (Dragging) your finger on the screen to the left moves the data forward in time, and to the right moves backward in time.

Run Buttons

To select a run for analysis, tap on a Run button and select a run from the list.

When a run's location has beacons defined, you can select laps and segments to analyze via the Lap and Seg buttons. Use the up/down arrow buttons to select the next/previous lap or segment.

Tap on the lock/unlock icon to hold the associated data at the current time within the run or release it so the data can move forward/backward in time by sliding your finger across the screen or tapping the time movement buttons in the toolbars.

Toolbar Buttons

Indicates that Run A and Run B are linked together by their position on the track. This allow you to compare data for both at the same position on the track. Tapping on this button unlinks Run A and Run B from one another.

Indicates that Run A and Run B are not linked to one another. This allows them to allows you to see their track position over time.

Move the data to be start of the run

Move backward in time (large increment)

Move forward in time (large increment)

Move backward in time (small increment)

Move forward in time (small increment)

Add a beacon at the current track position. Beacons are associated with a location, so it is important that runs are correctly associated with the appropriate location (See Settings and Results).

Remove all beacons from the run's location.

QView™

QView™ is an innovative way to visualize the performance of a car as it drives around the track. It combines lateral acceleration, longitudinal acceleration, and speed differences into a single graphic that is easy to grasp.
QView™ requires the following values to be in the flight recording:

• Latitude
  
• Longitude
  
• LatG
  
• LongG
  
• Course

Qview™ works like this: The width of each block is proportional to lateral acceleration The length (in the direction of travel) of each block is proportional to longitudinal acceleration The inside color is red for braking, blue for accelerating. Intense red is hard braking, intense blue hard acceleration. White means you are neither braking nor accelerating.

The green outline indicates where B is faster than A, orange where it is slower. This coloring only appears when A and B are at approximately the same point on the track.

Due to limitations of the iPhone 3G/3GS built-in GPS module, the data recorded by Flight may suffer from inaccuracy. This inaccuracy is apparent when the track map shows many straight lines between various point on the track and when track map does not properly match the actual driving line.

High levels of accuracy can be achieved by using an external high performance GPS module available from MaxQData. See the MaxQData Quantum section for details.

When used standalone on an iPhone 3G or 3GS, the MaxQData app is for demonstration purposes only.
