✈️ Torque Effect (Engine Reaction)
📌 Propeller rotation creates an equal and opposite reaction on the aircraft
📍 Key ATPL Concepts
✅ Torque Reaction
• Engine turns propeller → aircraft reacts opposite
• Causes rolling tendency around longitudinal axis
➡️ Typical Effect
• For clockwise prop (cockpit view) → aircraft rolls left
• One of the left-turning tendencies
➡️ When strongest
• High power
• Low airspeed
• High angle of attack (e.g. takeoff, climb)
✅ Pilot Correction
• Apply right aileron to counter roll
• Maintain wings level
🧠 Exam Tip (Very Important)
➡️ Torque = roll (NOT yaw)
➡️ Opposite direction of prop rotation
➡️ Most noticeable at high power / low speed

Airlines are struggling but China’s ‘Big Three’ face a tougher year than most:
China’s biggest airline stocks have suffered more than others since the war in Iran began, as a combination of factors weighs them down.

The country’s carriers -- which swung to a quarterly profit in the beginning of 2026 -- are caught in a pincer of higher fuel costs and a price-wary domestic market being eroded by high-speed rail. Jet fuel prices soared after the U.S. and Israel launched attacks on Iran in February.

And while many global peers are hedged against swings in fuel prices, Chinese airlines hedge little of their fuel purchases, making them vulnerable to a harder hit from the prolonged rise in oil prices.

The so-called “Big Three” — Air China
, China Eastern
and China Southern Airlines
— together account for the bulk of domestic capacity and are expected to record a combined net loss of 22 billion yuan ($3.2 billion) in 2026, swinging back into the red after the profitable first quarter, according to HSBC analysts.

Their share priced have fallen around 30% since the war began, among the worst performers in the region, according to LSEG data. Singapore Airlines
shares were down 9% as of Thursday over the same period, Korean Air Lines slipped 7%, Japan Airlines
down 20%, and ANA Holdings
18%.

✈️ Skyward Bound: The 4 Principles That Keep Planes in the Air
Ever wondered how a massive aircraft defies gravity and soars through the sky?
It all comes down to four fundamental mechanics of flight:
1. Generating Lift (Wings)
Faster air over the curved top surface creates lower pressure — thanks to Bernoulli’s Principle and the Coanda Effect. That’s what pushes the plane upward.
2. Creating Thrust (Engines)
Jet engines or propellers generate powerful forward thrust to overcome drag and propel the aircraft through the air.
3. Overcoming Drag & Gravity
In level flight, lift perfectly balances weight, and thrust counters drag. All four forces in perfect harmony.
4. Achieving Control (Surfaces)
Pilots use ailerons, elevator, and rudder to control pitch, roll, and yaw — mastering every turn, climb, and descent.
Understanding these principles is the foundation of every pilot’s journey and every aircraft’s design.
Whether you're an aviation enthusiast, a student pilot, or just love the science of flight — this is the ultimate visual breakdown.
