Welcome to the CH-Academy

You will learn what terms like arm, moment, reference datum, and pitch attitude really mean — and how they interact to define the aircraft’s center of gravity.
We explain the role of altitude variation, load distribution, and why even minor shifts matter for flight performance.

You will learn how to level the aircraft, drain fuel, align the datum, apply pitch attitude correction, and verify the aircraft’s configuration.
We guide you through each step to ensure repeatable and compliant weighing results — regardless of aircraft type.

Learn how to determine the empty weight and accurately calculate the center of gravity using the arm × moment method.
This module focuses on the aircraft types you operate — ensuring every calculation is relevant and practical.
 

Incorrect weight and balance isn’t just a paperwork issue — it’s a safety risk.
We show you how errors in CG, MAC, or empty weight can lead to instability, control issues, or regulatory violations.
This section explains why accurate aircraft weighing is essential for safe operations
