Almost everyone learning to fly a drone starts in GPS mode. Release the sticks and the aircraft stops where it is, which lowers the pressure and lets you learn the basic manoeuvres safely. The problem is that a pilot who has only ever flown in GPS mode cannot respond when something goes wrong. That is why attitude mode practice matters.
The two modes ask the aircraft to do different jobs
In GPS mode the flight controller combines satellite signals, the barometer and inertial sensors to hold an absolute position and altitude. Push it off station with wind and it leans back the other way by itself. You tell it where to go; it handles how to stay put.
Attitude mode is different. What the aircraft holds here is not position but attitude - its tilt. Centre the sticks and it levels off, but it does not hold position. Wind pushes it away, momentum carries it on, and keeping it in place is entirely your job.
- GPS mode: holds position and altitude; stops on centred sticks. Good for filming and for early learning.
- Attitude mode (자세 모드): holds level only; the aircraft keeps drifting even with centred sticks. Your inputs translate directly into movement.
- More manual modes: depending on the aircraft there are modes that do not even self-level. These are for experienced pilots.
GPS can disappear at any time
The main reason to practise attitude mode is that GPS is never guaranteed. Between tall buildings, under bridges, and around steel structures, satellite signals are reflected or blocked, and radio interference has the same effect. When the signal degrades, many aircraft fall back automatically into something close to attitude mode.
A pilot who has only flown in GPS mode suddenly faces an aircraft that drifts. They release the sticks expecting it to stop, it does not, and the accident happens in those few seconds of confusion. A pilot used to attitude mode notices the change immediately and simply takes over the station-keeping.
Attitude practice also raises your general skill. Holding position without help forces you to anticipate momentum and wind and correct pre-emptively. That sense carries over and makes your GPS-mode flying more precise too.
A safe way to learn it
Attitude mode carries risk, so approach it in stages.
- Stage 1, simulator: rehearse the feel of drift with no risk to the aircraft. The cheapest and safest starting point.
- Stage 2, open space: begin in a clear area with no obstacles. Do not fly too low, though; you need enough height to recover.
- Stage 3, short switches: stabilise in GPS mode, switch to attitude for a few seconds, then switch back. Extend the interval gradually.
- Stage 4, nose-away hold: hold position with the tail towards you.
- Stage 5, heading changes and travel: once that is comfortable, add heading changes and straight-line movement.
Always know where the mode switch is by feel so you can return to GPS mode instantly. Practising with an instructor, or at minimum with a spotter, is far safer than doing it alone.
What it means for the exam and for work
The practical assessment for pilot certification includes handling a situation in which the aircraft is not behaving normally. The gap between candidates who have flown in attitude mode and those who have not is obvious in that item. Assessed items and criteria vary by class and by notice, so confirm them with the Korea Transportation Safety Authority (한국교통안전공단, TS).
The same applies to professional work. Structural inspection, indoor filming and work under bridges - sites with weak satellite reception - keep growing. Whether you can fly in attitude mode decides the range of jobs you can accept.
Light Beyond Drones runs class 1 to class 3 practical courses in Daejeon and includes attitude mode transitions in a controlled environment. It is an uncomfortable thing to attempt alone, so if you would like to build it up step by step, tell us about your flying experience and get in touch.
