✈️ FRONT SYMBOLS (Meteorological Fronts)

📌 Front symbols on weather charts indicate the type of front and its direction of movement.

● Key ATPL Concepts
🔵 Cold Front → Blue triangles
• Rapid uplift
• Showers and thunderstorms
• Cooler air follows

🔴 Warm Front → Red semicircles
• Gradual uplift
• Continuous rain
• Warmer air follows

🟣 Occluded Front → Purple triangles + semicircles
• Cold front overtakes warm front
• Extensive cloud and precipitation

🔴🔵 Stationary Front → Symbols on opposite sides
• Little or no movement
• Persistent cloud and rain

☁️ Aloft Symbols → Hollow symbols
• Represent upper-level fronts

🔑 Important Rules
• Triangles = Cold Front
• Semicircles = Warm Front
• Symbols point in the direction of movement
• Filled = Surface
• Hollow = Aloft

📝 Exam Tip (Very Important)
➡️ Occluded front = Cold front catches warm front
➡️ Stationary front = Front is not moving
➡️ Direction of symbols = Direction of movement

✈️ Q Codes in Navigation

📌 Q codes define bearings to/from station and true vs magnetic

📍 Key ATPL Concepts
✅ QDM
• Magnetic bearing to the station
• What you fly to reach the station

✅ QDR
• Magnetic bearing from the station
• Your radial from the station

✅ QTE
• True bearing from the station
• Same as QDR but true reference

✅ QUJ
• True bearing to the station
• Same as QDM but true reference

➡️ Quick Logic
• DM = to (Magnetic)
• DR = from (Magnetic)
• Add T → True (QTE / QUJ)

🧠 Exam Tip (Very Important)
➡️ QDM + 180° = QDR
➡️ QTE + 180° = QUJ
➡️ Always check: TO or FROM + Magnetic or True
