Step 1: Outline Basic Shapes
Fuselage: Begin with a long, narrow oval shape for the body of the aeroplane.
Cockpit: Draw a small oval at the front of the fuselage for the cockpit.
Wings: Add two large, thin rectangles extending from either side of the fuselage for the wings.
Tail: Sketch a smaller rectangle at the back of the fuselage for the tail wing.
Engines: Add two small ovals underneath each wing to represent the engines.

Step 2: Add Details to the Aeroplane
Windows: Inside the cockpit oval, draw small rounded rectangles for the aeroplane windows.
Tail Fin: On top of the rear end of the fuselage, draw a vertical triangle for the vertical stabilizer or tail fin.
Wing Flaps: Add two lines on each wing to represent the flaps.

Step 3: Refine the Structure
Landing Gear: Draw two small circles (one under each wing) for the landing gear.
Engines Details: Add lines to divide the engine ovals to show engine detailing.

Step 4: Add Shading and Texture
Body Shading: Lightly shade under the wings and fuselage to add depth.
Window Highlights: Add small curved lines at the tops of the windows.
Engine Shading: Add light shading to the bottom of each engine.

Step 5: Final Touches
Clouds: Draw soft cloud shapes around the aeroplane to show it flying in the sky.
Movement Lines: Add a few dashed lines behind the aeroplane to show motion.
Final Details: Add any final window or structural details to enhance the aeroplane’s realistic appearance.
