Seven new Academy articles — and five new device guides

LX Academy started as a handful of articles about the things pilots ask us at shows. It is now twenty-three, and today we are publishing the biggest batch yet: seven new pieces, each written at the same desks in Celje where the instruments are designed, and each built around an interactive model you can pull apart rather than a diagram you have to take on trust.

What is new

• The airspace you cannot see is still there — classes, floors and ceilings in three different altitude references, and why a flight-level base moves with the weather while an AGL lid does not.
• The thermal assistant is drawing your last turn — what the coloured circles actually are, and what an off-centre circle costs you in metres per second.
• Who can actually see you — FLARM, Mode S, ADS-B and TCAS are four conversations on four frequencies. Switch on what you carry and read the table.
• One cable behind the panel — why instruments share two wires, what CAN does with them, and the 120 Ω rule behind most intermittent faults.
• The six-pack did not disappear, it moved — a live PFD you can fly with sliders, including what the stall speed does when you roll into 60°.
• The wing does not know how fast you are going — a wing stalls at an angle, not a speed, and the placard number is true at exactly one weight and one bank.
• The engine is talking in numbers — EGT is a mixture instrument, CHT is the limit, and a logged trend finds failures a red line never will.

Every one of them has a working model in the middle of the page. Drag the QNH and watch a TMA floor slide down toward you. Add a vario delay and see the strongest part of a thermal appear in the wrong place. Lean an engine past peak EGT and watch the cylinder head cool down. The point is not the animation — it is that the numbers behind our instruments are not secret, and a pilot who has played with them once flies differently.

Five new device guides too

Alongside the theory, the knowledge base gained five practical guides written for owners and installers: Era setup and first flight, iris EFIS installation and calibration, upgrading an LX 4000 to 7007 system to the LX 10K, how a NAVIA system fits together, and the CAN bus wiring rules that prevent the fault every avionics shop knows by heart.

All of it is free and open — no login, no email address, no marketing filter. If something you keep wondering about in the cockpit is still missing, tell us: the engineers pick the next article from what pilots ask.
