Aircraft Systems Engine The DA20-C1 is equipped with a Continental, 4-cylinder, IO-240-B (fuel injected, opposed, 239.8 cubic inch) engine rated at 125 horsepower at 2800 RPM. The engine is direct drive (crankshaft connected directly to the propeller), horizontally opposed (pistons oppose each other), piston driven, fuel injected and normally aspirated (no turbo or supercharging).
diameter of 76 inches. Maximum RPM (red line) is 2800 RPM. Landing Gear The DA20-C1 is equipped with Fixed tricycle type landing gear. The main gear is mounted to aluminum spring struts mounted to the fuselage below the wings. A castering nose wheel mounted on the front of the aircraft steers 60 degrees either side.

from the filler neck through the fuselage bottom skin to the exterior of the airplane. The vent line is the translucent plastic hose adjacent to the left wing root. The tank has an integral sump which must be drained prior to each flight, by pushing up on the brass tube which protrudes through the underside of the fuselage.
1.10 Electrical System A 12 V battery is connected to the master bus via the battery circuit breaker (50 amps). The 40 amp alternator is attached to the engine near the propeller hub. The alternator feeds the main bus via the generator circuit breaker (50 Amps). Both circuit breakers can be triggered manually.

processing to determine the aircraft’s magnetic heading. The temperature probe provides outside air temperature (OAT) data to the ADC. The Garmin GNS 430 GPS provides input to the AHRS and PFD/MFD. G500 equipped Diamonds do not have a conventional turn coordinator. A slip-skid indicator is located at the top of the attitude indicator.
Performance, Weight & Balance Airspeed Limitations Speed KIAS Remarks Do not make full or abrupt control movement above this speed. Under certain conditions the airplane may be overstressed by full Maneuvering Speed control movement. Do not exceed this speed with flaps in takeoff position.

Takeoff Procedures Normal Takeoff (Flaps T/O) 1. Select Flaps T/O ◦ 2. Line up on centerline positioning controls for wind 3. Smoothly apply full power 4. Check engine gauges 5. Right rudder as required for turning tendencies 6. “Airspeed Alive” 7.
4.2 Short Field Takeoff (Flaps T/O) 1. Select Flaps T/O ◦ 2. Line up on centerline positioning controls for wind 3. Hold brakes 4. Smoothly apply full power 5. Check engine gauges 6. Release brakes 7. “Airspeed Alive” 8. Briskly rotate at 51 KIAS 9.
4.3 Soft Field Takeoff (Flaps T/O) 1. Select Flaps T/O ◦ 2. Roll onto runway with full AFT stick – minimum braking – do not stop 3. Smoothly apply full power holding full AFT on the stick – check engine gauges 4.
Landing Procedures VFR Landing Briefing Procedure Announce verbally: 1. Type of Approach & Landing Runway 2. Aiming & Touchdown Point 3. Wind Direction & Speed Pattern Altitude 4. Go-Around Criteria & Plan Example: “This will be a normal flaps full landing on runway 13 with an intended touchdown point of the one thousand foot markers, aiming point will be 3 stripes prior, we can expect a left crosswind of 5 knots”.
Normal Landing (Flaps LDG) 1. Complete the “Approach Checklist” before entering the airport; devote full attention to aircraft control and traffic avoidance 2. Slow to 90 KIAS prior to entering downwind or traffic pattern and complete the before landing checklist 3.
Short Field Landing (Flaps LDG) 1. Complete the “Approach Checklist” before entering the airport; devote full attention to aircraft control and traffic avoidance 2. Slow to 90 KIAS prior to entering downwind or traffic pattern and complete the before landing checklist 3.

1. Complete the “Approach Checklist” before entering the airport; devote full attention to aircraft control and traffic avoidance 2. Slow to 90 KIAS prior to entering downwind or traffic pattern and complete the before landing checklist 3. Enter traffic pattern at published TPA (typically 1,000’ AGL) 4.

Private ACS Requirements: ALT +/- 100’ ◦ ◦ Bank +/- 5 HDG +/- 10 Speed 5-10kts above V NOTE: Minimum safe altitude for this maneuver is 1,500’ AGL. Slow flight is performed in the landing configuration. 1. Perform clearing turns 2.
Power On Stalls Private ACS Requirements: ALT +/- 100’ ◦ ◦ Bank not more than 20 HDG +/- 10 NOTE: Minimum safe altitude for this maneuver is 1,500’ AGL. Power on stalls are performed in the takeoff configuration. 1. Perform clearing turns 2.
Power Off Stalls Private ACS Requirements: ALT +/- 100’ ◦ ◦ Bank not more than 20 HDG +/- 10 NOTE: Minimum safe altitude for this maneuver is 1,500’ AGL. Power off stalls are performed in the landing configuration. 1. Perform clearing turns 2.
Ground Reference Maneuvers All ground reference maneuvers are performed at 1,000’ AGL and 90 kts mimicking the traffic pattern. They are started on a downwind leg simulating traffic pattern entry and are performed in the “clean” configuration. Before descending for the maneuver it is important to visually scan the area for obstructions and a safe landing spot in case an emergency landing is necessary.
