ACROWRX - Time History

📢 - INFO

This page provides detailed information about how to use the time history chart in ACROWRX.

Time History

Time history shows a graphical representation of your flight over time. Engineers will love it, and pilots will learn to love it.

Time history is a powerful tool that helps you to:

• Find events during your flight - for instance, a double wing dip maneuver always has a very distinctive shape along the roll rate time history. The same applies for arcs, snaps, etc.
• Check how you are actually performing the maneuver - for instance, in a rolling turn, looking at the altitude or height time history allows you to see how much altitude variation you have, or roll rate time history will show you how steady your roll rate is.

Data Channels

The time history can display a wide range of data channels. Each chart panel has a data channel selector dropdown that lets you choose which channel to display. Click the dropdown arrow to open a scrollable list of all available channels.

Primary Flight Channels

Channel	Unit	Description
G-load	g	Load factor
Roll rate	deg/s	Roll rate
Speed	km/h, mph, or knots	Ground speed (unit from right menu)
Altitude	m or ft	Altitude AMSL
Box Heading	deg	Heading relative to the box (0° = positive X-axis)
Height	m or ft	Height above judge (AGL)

Additional Channels

Channel	Unit	Description
Pitch rate	deg/s	Pitch rate
Yaw rate	deg/s	Yaw rate
Long. Accel	g	Longitudinal acceleration
Lat. Accel	g	Lateral acceleration
Yaw	deg	Yaw angle
Pitch	deg	Pitch angle
Roll	deg	Roll angle
Loop Radius	m	Computed loop radius (R = V²/a)

Diagnostic Channels

Channel	Description
GNSS1 / GNSS2 #Sat	Satellite count for each GNSS receiver
GNSS1 / GNSS2 Fix	Fix quality for each GNSS receiver
Yaw / Pitch / Roll Uncert	Attitude uncertainty estimates
Vel / Pos Uncert	Velocity and position uncertainty estimates
ADC0 – ADC7	Analog-to-digital converter channels (control position sensors, etc.)

Chart Window Size

Use the and buttons on the chart to zoom the time window in or out. A larger window shows more of the flight at once, while a smaller window zooms in for finer detail. The playback cursor remains centered as you adjust the window size.

Playback Cursor

A vertical cursor line moves across the chart in sync with the 3D views (Judge, Chase, Map). The airplane's current position in the time history is always visible. You can click on the chart to jump to any point in the flight.

Markers

Markers that you drop (using keyboard keys 0–9) are also marked in the time history as vertical indicator lines. The last marker dropped can be moved with the mouse (click and drag on the chart). Use C to clear all markers.
