DA20 and Tecnam P2008 Aircraft Systems and Flight Patterns
DA20 Aircraft
The DA20 is a two-seat training aircraft with a low-wing design. It is easy to fly and commonly used for basic flight training.
Engine
The aircraft uses a fuel-injected, air-cooled engine powered by AVGAS fuel. It is a direct-drive engine with magnetos.
Oil System
The oil system lubricates and cools the engine. The acceptable oil quantity is between 4 and 6 quarts.
Propeller
The DA20 has a two-blade fixed-pitch propeller connected directly to the engine.
Landing Gear
It uses a fixed tricycle landing gear. The nose wheel is castering and turns with rudder or brake pressure.
Braking System
The brakes are hydraulic and operated with toe brakes from the pedals.
Flaps
The aircraft has electric flaps with cruise, takeoff, and landing positions. Flaps increase lift and drag.
Pitot-Static System
This system provides information to instruments like the airspeed indicator and altimeter.
Stall Warning
The aircraft includes a stall warning horn that activates before the stall speed.
Fuel System
Fuel is stored in the wing tanks and checked through fuel drains to detect contamination.
Electrical System
The electrical system powers avionics, lights, and other aircraft equipment.
Ignition System
The ignition system uses magnetos to create the spark needed for combustion.
Tecnam P2008 Aircraft
The Tecnam P2008 is a two-seat training aircraft with a high-wing design that gives better visibility from the cockpit.
Engine
It uses a piston engine designed for training and VFR operations.
Carburetor
The carburetor mixes fuel and air before combustion using the Venturi effect.
Carburetor Heat
Carb heat is used to prevent or remove ice inside the carburetor, especially during humid conditions or low RPM descents.
Advantages and Disadvantages
- Advantages: The carburetor system is simple, cheap, and easy to maintain.
- Disadvantages: It is less efficient than fuel injection and can suffer from carburetor icing.
Fuel System
Fuel is stored in wing tanks and passes through the selector and filters before reaching the engine.
Flaps
Flaps are used during takeoff and landing to increase lift and drag. They help the aircraft take off at lower speeds and land in shorter distances. During landing, flaps also help the aircraft descend more steeply while maintaining a safe speed.
Traffic Pattern
Upwind
The aircraft climbs straight ahead after takeoff while maintaining runway heading.
Crosswind
The aircraft turns 90 degrees from the runway to continue the circuit.
Downwind
The aircraft flies parallel to the runway in the opposite direction and performs landing checks.
Base
The aircraft turns toward the runway to prepare for final approach.
Final
The aircraft aligns with the runway for landing. If the approach is unstable, a go-around is performed.
Emergency and Operational Procedures
Flooded Engine Start
Too much fuel enters the engine, making the mixture too rich. The engine is cleared by cranking with more throttle.
Engine Fire During Start
Excess fuel ignites during engine start. Procedure:
- Continue cranking
- Mixture CUTOFF
- Fuel OFF
- Magnetos OFF
Warm vs. Cold Start
Cold start needs more priming fuel. Warm start needs less fuel because the engine is already hot.
