🌦️✈️ SIGWX charts tell the weather story before the flight.

Turbulence, icing, CBs, jetstreams, fronts — all on one chart. Know how to read it, fly smarter.

⚠️ MICROBURST ON FINAL APPROACH ⚠️✈️

One of the most dangerous weather phenomena in aviation.

The scary part?
At first, it actually feels helpful.

➡️ The aircraft suddenly encounters a strong headwind
➡️ IAS increases
➡️ Lift increases
➡️ The aircraft rises above the glide slope

But seconds later comes the real danger:
⬇️ Severe downdraft
⬇️ Rapid loss of airspeed
⬇️ Tailwind shear
⬇️ High sink rate close to the ground

A microburst can quickly turn a stable approach into an unrecoverable situation if not recognised immediately.

That’s why windshear escape procedures are critical knowledge for every pilot. 🌩️

Primary rainbow from the cockpit. 🌈

ATPL theory spoiler: this isn’t ‘just’ pretty weather – it’s sunlight refracted, reflected and dispersed in countless raindrops at a very specific angle to your eye.
Same optical illusions that give you a rainbow can also mess with your visual perception on approach. Still think ‘Meteorology’ and ‘HPL’ are boring subjects?

⚠️ “PULL UP! TERRAIN!”

Those famous cockpit warnings exist because pilots once had almost no protection against CFIT accidents — situations where a fully functioning aircraft was unintentionally flown into terrain.
GPWS (Ground Proximity Warning System) changed aviation safety forever ✈️

Using inputs from:
• Radio altitude
• Vertical speed
• Airspeed
• Aircraft configuration
• Glide slope deviation

…the system continuously checks whether the aircraft is getting dangerously close to the ground.

And when needed, it TALKS to the crew.
🔸 SINKRATE
🔸 PULL UP
🔸 DON’T SINK
🔸 TOO LOW GEAR
🔸 GLIDESLOPE
🔸 BANK ANGLE

⚖️✈️ Forward CG vs Aft CG — why does it matter?

The position of the Centre of Gravity affects much more than just loading limits.

➡️ Forward CG:
• More tail-down force required
• More induced drag
• Higher fuel consumption
• Greater longitudinal stability

➡️ Aft CG:
• Less tail-down force required
• Less induced drag
• Lower fuel consumption
• Reduced longitudinal stability

That's why pilots love an aft CG for performance and efficiency — but only within limits. Move too far aft and stability can deteriorate rapidly.

📚 Exam tip:
Forward CG = more stable, less efficient.
Aft CG = more efficient, less stable.

Orographic Fog!

Orographic fog (hill fog) forms when moist air is forced to rise over terrain ⛰️, cooling to dew point along the slope 🌫️. It can develop day or night under stable conditions and clears with downslope (katabatic) wind or surface warming 🌬️🔥.

In aviation, it often appears as cloud stuck to terrain — but for pilots, it’s still fog where it matters.
