What is a CH10 file?

CH10 files mostly belong to iFlightPlanner.

IRIG 106 Chapter 10 data files store raw telemetry and sensor data in a specialized binary format. They follow the IRIG 106 standard where data is organized into packets, with each packet containing time-stamped measurements from different sensors.
These files are chiefly used in test and measurement settings such as flight tests, where precision in data acquisition is required.
Key details provided by FilExt.com include:

Telemetry Data Storage: The file holds data from sensors and instruments, logged with precise timestamps.

Structured Binary Format: It conforms to the IRIG 106 Chapter 10 standard, ensuring data is organized into defined chapters.

Specialized Software Access: To open and view these files, use tools like iFlightPlanner from IRIG106.

Some CH10 files are also produced by the Calculex PCM200 system. In this case, the file acts as an audio log that captures raw audio signals. These files require Calculex’s own software for proper playback and analysis, detailed on their website at Calculex.

FilExt.com note: This file format is not for casual use but is tailored for precise data analysis. Users should rely on the proper applications to interpret both telemetry and audio log information accurately.

How do you open CH10 files?

You need a suitable software like iFlightPlanner to open a CH10 file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your CH10 file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a CH10 file directly in the browser:. Just drag the file onto this browser window and drop it.

Programs that open and convert CH10 files:

iFlightPlanner
See the previous paragraphs to learn more about the main application. CH10 files are often referred to as iFlightPlanner data files because this type of file is primarily created or used by this software.
IRIG 106 (Original Recording File) by Range Commanders Council
IRIG 106 is a comprehensive telemetry standard to ensure interoperability in aeronautical telemetry application at RCC member ranges. IRIG 106 is developed and maintained by the Telemetry Group of the Range Commanders Council. Upon data download to a host computing platform, all Original Recording Files and or Modified Recording Files shall use the file extension *.ch10 (or *.c10 extension for use on systems with a 3 character extension limit). The use of this standard extension will indicate that any Original Recording File and or Modified Recording File on a ground computing or storage platform shall be in compliance with this section 10.11 of the standard.

CH10 file format:

Why is it important to know the file format? This is the only way to find out which program to use to open the file. The file format can be deduced from the file extension and the signature. Frequently, however, one file extension is used by different programs for different file formats, and one file format for different file extensions. So a detailed analysis of a file is vital in order to determine the format and the associated program. Below you will find our evaluation of the CH10 files:

CH10 is rarely used as a file extension and includes different formats for the applicable programs. The two most popular formats are as follows:

55% of all CH10 files start with the magic bytes 25 EB 00 00, which are always the first bytes of this file format. If you open these files in a text editor, you will see only illegible characters. CH10 files can be up to 1 GB in size, but are often around 33 KB - 150 MB. The file type was used 20 years ago but is still in use today. The following keywords are characteristic: DSI-1, G\DSI\N:1;, DST-1 and TMATS. An example of a file name is 687200109140804.ch10. Such files sometimes refer to prefix and calculex.
15% of all CH10 files have the same signature 23 00 44 00 61 00 74 00 65. They consist of illegible, cryptic characters. The files are often between 68 bytes and 1 KB in size. The following keywords are characteristic: Date, File Name and PacketOffset. Such files are related to acquisition, dataagc and irig.

All other CH10 files (30%) have no uniform format, such as Date. They are often associated with data. If you want to find out what your CH10 file contains, drag and drop it onto this page.

How to solve problems with CH10 files

Associate the CH10 file extension with the correct application.
Update your software that should actually open binary data files. Because only the current version supports the latest CH10 file format. Search, therefore, e.g. on the manufacturer website after an available iFlightPlanner update.
To make sure that your CH10 file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
