What is the minimum and maximum fuel pressure for the DA-40?

Study These Flashcards

Minimum: 14 PSI
Maximum: 35 PSI

What is the maximum cylinder head temperature:

Study These Flashcards

500ºF

What are the minimum and maximum propeller diameters?

Minimum: 72 inches
Maximum: 74 inches

What are the low and high propeller pitch angles?

Study These Flashcards

High: 29º +/- 1º
Low: 13.9º +/- 0.2º

What does the following warnings mean?

) OIL PRESS LO
) FUEL PRESS LO
) FUEL PRESS HI
) ALTERNATOR
) STARTER ENGD
) DOOR OPEN

Study These Flashcards

) Oil pressure less than 25 PSI
) Fuel pressure less than 14 PSI
) Fuel pressure greater than 35 PSI
) Alternator failure
) Operation of starter without key in start position
) Door not completely closed

What do the follow cautions mean?

) PITOT OFF
) PITOT FAIL
) L FUEL LOW
) R FUEL LOW
) LOW VOLTS
) TRAFFIC

Study These Flashcards

) Pitot heat not switched on
) Fault in pitot heating system
) Fuel quantity in left tank less than 3 USG (+/- 1)
) Same as above
) On-board voltage less than 24 volts
) Calculated time to closest approach of intruder is <30 seconds

What is the maximum take off mass for normal and utility category variations of DA-40? What is the maximum landing mass and maximum ramp mass? What happens if you exceed these limits?

Study These Flashcards

Normal: 1200kg
Utility: 980kg
Max LDG mass: 1150kg
Max ramp mass: 1204kg
Exceeding these limits will cause overstressing of aircraft as well as degradation to flight characteristics and flight performance.

Where is the CoG datum located in the DA-40?

Study These Flashcards

2.194m in front of most forward point of root rib on stub wing.

What is the most forward position of the CoG when weight is between 780kg-980 kg and 1200kg respectively?

Study These Flashcards

4m aft of DP 780-980kg

2. 48m aft of DP 1200kg

What is the most rearward location of the CoG? What happens if you exceed the CoG limits?

Long range tank – 2.55m aft of DP. | Exceeding CoG limits reduces controllability and stability of aircraft.

What manoeuvres are and are not permitted on a normal category DA-40?

All normal flight manoeuvres Stalling (except dynamic stalling) Lazy eights, chandelles, steep turns and similar manoeuvres where AoB does not exceed 60° Aerobatics, spinning not permitted.

What manoeuvres are and are not permitted on a standard category DA-40?

Same as above but turns up to 90° | Standby attitude gyro gets affected if AoB is more than 60° so can only perform above if gyro is not needed for flight.

What are the positive and negative load factor values for both normal and utility category?

Normal category: Positive: 3.8 With flaps: 2.0 Negative: -1.52, 0 at VNE Utility: Positive: 4.4 With flaps: 2.0 Negative: -1.76, -1 at VNE

What is the memory item for RPM high (overspeed)?

``` Throttle - retard Oil pressure - check Propeller - low RPM Airspeed - reduce Once RPM below red line Throttle - as required ```

What is the memory item for engine fire during start?

``` Starter: Keep winding Fuel tank selector: Off Fuel pump: Off Throttle: Open If fire continues: Masters off and abandon aircraft ```

What is the memory item for engine fire during flight?

Cabin heat: Off Fuel tank selector: Off Throttle: Full open Fuel pump: Off

What is the memory item for electrical fire in flight?

Emergency switch: On (IFR) Master: off Cabin heat: off

What is the memory item for an over voltage?

ESS Bus Switch: ON | ALT Switch: Off

What are the speeds for the following? 1. ) Cruise climb 2. ) Best RoC 3. ) Best AoC 4. ) Max operating speed in turbulent air 5. ) Normal final approach speed (LDG flaps) 6. ) Flapless final approach speed 7. ) Short field landing final approach speed 8. ) Max demonstrated crosswind

1. ) 90 kts 2. ) 80 kts 3. ) 70 kts 4. ) 129 kts 5. ) 70 kts 6. ) 75 kts 7. ) 65 kts 8. ) 20 kts

When performing magneto check during run-ups, what could an out of limit check indicate? How can you fix it?

Build up of carbon on the spark plugs The engine should be run at high power for approximately 30 seconds to burn off the carbon build up. Can be repeated for 2-3 times before abandoning flight.

What is the climb gradient required for a go around? What are the conditions?

``` Reaches constant climb gradient of 75% (500 fpm) in following conditions: 1200kg mass Take-off power setting LDG flaps 73kt ISA ```

What are is the fuselage made out of? What structural design does it incorporate? What are the two main bulkheads?

Glass fibre reinforced plastic. Semi-monocoque. Fire protection on firewall is a special fire-resistant matting which is covered on the engine side by stainless steel cladding. Two main bulkheads are GFRP/CFRP
