DASH-ONE Flashcards
RPM MAX AND NORMAL OPERATING RANGE?
2200 -2700 RPM normal operating range
2700 maximum RPM
ENGINE RPM LIMITS?
The engine must not be operated above 2700 RPM. Doing so will result in abnormal wear on bearings, counterweight rollers and other engine parts, concluding in possible engine failure.
However, since instances of inadvertent over speed do occur, it must be emphasized that reporting to the technician in charge is mandatory, if RPM exceed 2700 for more than 2 sec, or RPM exceed 2730 regardless of duration. The maximum RPM and duration of over speed condition should be stated.
OIL PRESSURE LIMITS?
60 - 85 PSI normal operating range
25 - 60 and 85 - 100 PSI caution range
25 PSI minimum for engine idling
100 PSI maximum for engine start and warm-up
OIL TEMPERATURE LIMITS?
50 –120 °C normal operating range
120 °C maximum
CYLINDER HEAD TEMP. LIMITS?
105 – 225 °C normal operating range
225 – 245 °C caution range
245 °C maximum
FUEL FLOW?
55% power corresponds to approx. 8 - 9 GPH
65% power corresponds to approx. 9 – 11 GPH
75% power corresponds to approx. 10 - 12 GPH
NORMAL CATEGORY?
AUW is less than 1200 kg.
1. Any maneuver used in normal flight
2. Stalls (except whip stall, hammer stall)
3. Lazy eights, chandelles, and steep turns with angle of bank not exceeding 60°.
The limiting load factors “G” are 4.4 positive and 2.2. negative.
UTILITY CATEGORY I?
AUW is less than 1125 kg.
- Any maneuver used in normal category
- Erect stall
- Spins
- Lazy eights, chandelles and steep turns with angle of bank exceeding 60°.
The limiting load factors “G” are 4.8 positive and 2.4 negative.
UTILITY CATEGORY II?
AUW being less than 1000 kg
- Any maneuvers used in utility category I.
- Rolling
- Looping
- Half roll (Split-S)
- Top roll (Immelmann)
The limiting load factors “G” are 5.4 positive and 2.7 negative.
AEROBATIC CATEGORY?
AUW is less than 900 kg
In the aerobatic category, the aircraft is limited to the same maneuvers as in utility categories I
and II. The limiting load factors “G” are 6.0 positive and 3.0 negative.
INVERTED FLIGHT?
Inverted flight is limited to 10 seconds due to engine oil system design.
AIRSPEED LIMITS?
Vne (Never exceed) 196 knots
Vno (Max. structural cruising) 154 knots
Va (Max. maneuvering) 143 knots
Vf Flaps extended (1-10°) 130 knots
Vfe Flaps extended (11-38°) 100 knots
TOTAL FUEL CAPACITY?
Between the main and the rear spar the root-section of each wing is equipped with an integral fuel tank holding 89 liters (23.5 US gallons) thus giving the aircraft a total fuel capacity of 178 liters (47 US gallons).
TOTAL OIL PRESSURE LOSS?
In case of total oil pressure loss the propeller blades move into coarse pitch (low RPM), thus preventing engine over speed.
FINE PITCH?
Fine pitch (high RPM) is maintained by means of oil pressure.
COARSE PITCH?
Coarse pitch (low RPM) is maintained by a mechanical device comprising counterweights which are acted upon by centrifugal force.
MANIFOLD PRESSURE VS RPM?
Due to the constant speed propeller, opening of the throttle will increase the manifold pressure, not necessarily the RPM.
UNUSABLE FUEL?
The root section of each wing - behind the main spar - forms an integral fuel tank holding a total of 23,5 US gallons (89 litres). The tanks can be completely emptied in level flight, but a normal amount of unusable fuel is 2.5 US gallons (10 litres) per tank. Thus, the total usable fuel is 42 US gallons (158 litres).
ACCURATE FUEL INDICATION?
Straight and level flight is required for accurate indication of fuel quantity
ELECTRICAL SYSTEM?
The electrical system is powered by an engine driven 28 V generator with built-in rectifier
GENERATOR CAUTION?
In case the voltage of the bus drops below 25 ± 0.5 V, the control box will close the circuit and turn on the GEN light. The cause for low voltage is normally a malfunction of the charging system.
ENGINE FIRE WARNING?
In case the temperature in the engine compartment rises to 275° C the bi-metallic switch will close a circuit, thus turning on the FIRE ENG warning light.
OIL PRESSURE WARNING?
The pressure switch is located at the fitting behind the oil pressure indicator. When the oil pressure is below 6.5 ± 2.0 PSI, the circuit is closed and the warning light illuminates.
ENGINE RPM LIMITS?
The engine must not be operated above 2700 RPM.
Reporting to the technician in charge is mandatory, if RPM exceed 2700 for more than 2 sec, or RPM exceed 2730 regardless of duration.
