Study Hubs · The Backbone Subjects
Every sub-topic, formula, and worked example for a subject in one place — organised the way you'd actually revise it, not the way a syllabus lists it.
081 · The Backbone Subject
Transonic aerodynamics, climb and turning performance, stalling, and stability — the one everyone's a little afraid of, worked through properly.
Open the hub →022 · Instruments & Nav
Approach categories, pressure datums, altimetry errors, TAS and Mach, compass errors, and inertial navigation systems.
Open the hub →031 · Mass & Balance
Datum, moment, and centre of gravity — the foundations this subject is built on, with a full worked CG example.
Open the hub →Podcasts · Free
Nine full episodes, free to stream right here — theory you can absorb on the drive to the airfield.
Did you know
A great circle track changes direction continuously — the shortest path between two airports is a curve on your chart, not a straight line.

Your compass has never pointed at the true North Pole — magnetic north is a moving target, currently drifting toward Siberia at around 40 km a year.

The Fascinating Facts of Flight
061 · Navigation · Geodesy
Why every long-haul flight plan curves toward the poles, how convergency changes your track continuously, and the math that makes it work.
Read →050 · Meteorology · Synoptics
Coastal lows, the Botswana high, and cut-off lows — how the subcontinent's pressure systems drive the weather you'll actually fly through.
Read →050 · Meteorology · Reports
Every group in a METAR encodes a measurement. The full decode logic — visibility, cloud groups, TSRA, and the trend codes that catch students out.

No Class B, D or E — SA runs on A, C, F and G. Who separates whom, where VFR stops, and why CTR and CTA are opposites.
Read →010 · Air Law · Altimetry
Climb on QNH, cruise on 1013.25, come home at the transition level — the agreement that keeps every altimeter telling the same story.
Read →010 · Air Law · Flight Planning
Z means GPS, S means VHF/VOR/ILS, X means a mercy flight — plus the one-hour, three-minute and five-percent rules.

A single cumulonimbus cell can hold more energy than a small city uses in a day — and its downdrafts can exceed an aircraft's ability to climb.
