Welcome back to ATPLation! ✈️ In this episode of our ATPL Mass & Balance series, we dive into the Medium Range Air Transport Aircraft exercises from CAP 696, the official CAA manual used for ATPL mass and balance questions. These examples reflect real-world airline operations and are designed to sharpen your skills in load sheet completion, CG determination, and operational decision-making—key elements for both ATPL exam success and professional flight preparation. ✅

📌 What you'll learn in this episode:

📘 About the CAP 696 Medium Range Exercises
These exercises are based on typical twin-engine jet aircraft used for short- to medium-haul commercial operations.

You’ll work with data such as:
🔹 Dry Operating Mass (DOM)
🔹 Maximum structural limits (ZFM, TOM, LM)
🔹 Passenger seating plans
🔹 Cargo holds and fuel tanks

You’ll be expected to perform full load sheet completion and CG verification using the provided tables and trim charts.

🧮 Key Calculations Practiced in This Episode
1️⃣ Zero Fuel Mass (ZFM)

Add Dry Operating Mass + payload

Compare with Maximum ZFM and adjust if exceeded

2️⃣ Take-Off Mass (TOM)

ZFM + fuel (minus taxi fuel if required)

Must be below Maximum TOM and suitable for runway conditions

3️⃣ Landing Mass (LM)

TOM minus trip fuel

Must not exceed Maximum LM, especially when planning alternate routing

4️⃣ Centre of Gravity (%MAC)

Calculate using provided arms, moments, and MAC reference

Ensure CG falls within published CG limits for the flight phase

5️⃣ Load Shifts and Corrections

Move passengers or cargo to correct CG

Recalculate moments and verify balance using trim sheets

📝 Interpreting CAP 696 Tables
Passenger seating charts indicate stations and arms

Baggage and cargo compartments are assigned unique moment arms

Fuel is listed by tank with associated moment contributions

Some exercises include ballast options or operational restrictions

🧠 ATPL Exam Tips
Get comfortable with CAP 696 layout—time management is key in the exam

Show all working steps clearly: mass × arm = moment

Always check that final figures meet structural and balance limits

Expect scenario-based problems requiring you to adjust the plan to stay legal and safe

Watch for trap answers—don't assume values are within limits until verified!

🎯 Why this episode matters:
✔️ CAP 696 Medium Range exercises are heavily featured in ATPL exams
✔️ Teaches you how to handle real-world airliner loading and dispatch situations
✔️ Helps you develop the confidence to manage complex data and make fast, safe decisions

🚀 Whether you're preparing for your EASA, UK CAA, or ICAO ATPL exams, or transitioning to the airline cockpit, this episode gives you the tools to master mass and balance procedures for medium-range commercial aircraft.
