RBAK
Basic Aviation Knowledge for RPAS
Map position, direction, time, units, energy, lift, drag, weight and balance, propellers, controls and remote pilot station principles.
Part 101 MOS C10 Schedule 4, Unit 1, items 1-9.
Lessons
Map Position, Latitude/Longitude and Runway Orientation
Use latitude, longitude, true and magnetic direction, runway numbers and clock-code references to describe where an RPA operation is happening.

Direction, Heading and Wind
Learn how aviation expresses direction, why heading and track are different, and how wind changes the path an RPA actually flies.
Source: RePL Study Guide pp. 11-35; Part 101 MOS C10 pp. 92-93.
Time, UTC and Date-Time Groups
Use aviation time correctly by reading four, six and eight figure groups and converting Australian local time to and from UTC.

Height, Altitude, Elevation and Aviation Units
Separate height, altitude and elevation, then apply the units remote pilots meet in aviation weather, charts and operations.

Aircraft Energy, Inertia and Speed
Understand potential energy, kinetic energy and inertia so aircraft behaviour, wind effects and stopping margin make practical sense.
Source: RePL Study Guide pp. 199-200; Part 101 MOS C10 p. 92.
Aerodynamics, Weight and Balance
Connect aerofoil terminology, forces, centre of gravity and loading limits to safe RPA operation.

Lift, Drag and Angle of Attack
See how changes in airspeed and angle of attack affect lift, drag, stall margin and endurance.
Source: RePL Study Guide pp. 200-213; Part 101 MOS C10 p. 93.
Propellers, Rotors, Thrust and Torque
Understand blade angle, pitch, thrust, torque and why propeller or rotor condition matters before launch.
Source: RePL Study Guide pp. 166-172; Part 101 MOS C10 p. 93.
Flight Controls, Axes and Climb
Relate pitch, roll, yaw, power, climb angle and control inputs to what the aircraft actually does.

Remote Pilot Station and Control Link
Identify the remote pilot station features that support control, telemetry, software, antennas and non-payload communications.
Source: RePL Study Guide pp. 175-183; Part 101 MOS C10 p. 93.
Performance, Wind Shear, Turns and Ground Effect
Preserve performance margin when weight, wind, heat, height, turns and descent airflow make the aircraft work harder.

Next step after study
Complete your Remote Pilot Licence training
The free study guide is a strong theory foundation. To actually be issued with a RePL, students still complete approved training, practical flying and assessment with a certified provider.
