The airplane may only be operated when its temperature prior to operation is not less than
- 20°C.
With ventilation inlet baffle installed: max OAT for Take-off: 15°C
15°C
How long can you fly with the emergency battery
90 minutes
Typical fuel weight
JET A1: 0,8 kg/ltr 3,03 kg/USG ==> ET fuel is heavier than AVGAS!

Where is the External Power Receptable
External Power Receptable
Essential bus switch ==> When is it used
When the alternator fails to disconnect unnecessary electrical consumers to supply battery power to essential electrical consumers
-
Performance data which are engine-power dependant cannot be determined by just using „Density Altitude“! Why?
-
he engine power output does not correspond to density altitude but pressure and temperature have their own, independent influence

Rückfluss when Fuel Schalter auf Emergency ist? Auf was muss mann achten?
45 USG/h (170 l/h) ==> The fuel valve must be switched back to the NORMAL position before the auxiliary tank indication reads zero!
How many fuel pump are installed?
2 parallel independent low pressure fuel pumps installed => Switching from ECU A and B the two independent electrical fuel pumps are switched as well
Main Tank (LeftWing) Besteht aus?
consists of an aluminum chamber => Return Fuel fliesst durch den auxiliary Tank und kühlt dort ab, bzw. anderes Fuel erhitzt sich => Fliest in separaten Leitungen durch den Auxiliary tank
Wie viele vents hat es in den beiden Fuel Tanks?
2 tank vents
a) Check valve with capillary: allows air to enter teh tank but prevents flow of fuel to the outside => equalize teh air pressure during the climb
b) pressure relief valve: protects the tank against high pressure if the tank will be overfilled
Neben der Kühlung des Fuel durch das Fuel im Auxiliary Tank, wie kann das Fuel noch gekplt werden?
Durch Luft
Outlet valve?
In each tank a coarse filter (finger filter) is fitted before the outlet =>To allow dreaming (Entwässern) the tank at the lowest pint of the fuel tank
drain
entwässern
Wie kann man das Fuel von hand kontrollieren?
Alternate Means for Fuel Quantity Indication => position is marked on the wing => is in the bag on the rear side of the pilot seat!
Cooling system is liquid cooled. es besteht aus?
1. radiator circuit ( Coolant heat exchanger): only open during hot coolant temperatures => Engine will warm up quickly
2. Bypass circuit (cabin heat exchanger): a coolant to air het exchanger = cabin heat
What's that?
Temp. Halten
What is that
radiator circuit ( Coolant heat exchanger): only open during hot coolant temperatures => Engine will warm up quickly
what's that
Bypass circuit
Coolant expansion tank: was macht der?
Coolant expansion tank allows coolant expansion and pressure adjustment
Turbo charger System: wie funktioniert das?
1. Compressor(Charger) compressed the air
2. Intercooler cooled it down = higher desnity => increases engine efficiency
3. Exhaust system collects exhaust gases and feed them to the turbine of the turbo charger
4. behind the turbine the exhausted gases are guides through an exhaust pipe
Oil pressure up; what hapens to the pitch of teh propeller?
Oil pressure up => pitch: up ==> RPM: down
Oil pressure down; what hapens to the pitch of the propeller?
Oil pressure down => Pich: down => RPM Up
2 separte oil systems
1. Lubrication Systems (Engine an Turbo Charger )
2. Gearbox and propeller Governor System
1. Lubrication Systems (Engine an Turbo Charger ) is cooled by ?
Is a wet sump lubrication ==> Warten eine Zeit bis Oil zurück fliesst! Oil is cooled by a separate cooler on the outside of the engine.
2. Gearbox and propeller Governor System
lubricates the gear and severs the governor system and teh regulation of the propeller ==> Inspection glass
Electrical System DA 40 besteht aus?
DA 40 has a 28 Volt DC system
1. Power generation 2. Storage 3. Distribution (Verteilung) 4. Consumers
DA 40 has a 28 Volt DC system
1. Power generation whats that?
70 Ampère alternator ==> Generator
In a main batterfy failure==> ENGINE MASTER connects the ECU backup battery to the alternator voltage regulator via a 10 A fuse ==> Only ECU B kann auch die Backupbattery zugreifen
DA 40 has a 28 Volt DC system
2. Storage ?
Main battery is stored in a 24 V, => A lead battery mounted behind the baggage compartment => Controlled by the ELECTRIC MASTER
DA 40 has a 28 Volt DC system
3. Distribution (Verteilung)
Electrical power is distributed via a hot battery bus, battery bus 1 and 2, ECU Bus, main bis, essential bus and the avionic bus
Hot battery bus
the hot battery bus is drectly connected to the main battery installed in the relay junction box => Power to the accessory (zusätzlich)power plug and the ELT
Battery Bus 1
connected to the main battery via the battery relay => controlled by the ELECTRIC MASTER key switch
=> power to teh battery bus 2 and heavy duty power to the starter
==> connected to the power input line of teh external power plug
Main Bus
Put the AVIONIC MASTER on to connect the main bus to the avionic bus => Separates the main bus from the battery bus => Main bus has no longer power !
Essential bus
essential is connected to the main bus => Normal
AVIONIC MASTER on => connecting essential bus to the avionic bus
ESSENTIAL BUS: Must be set on for separation of the essential bus from the main bus => the essential bus is then connected to the battery bus 2 which provides battery power for a limited time to the equipment essential for a safe landing
DA 40 has a 28 Volt DC system
4. Consumers
Individual consumers (Radio, fuel transfer etc.) connectey to the bus via automatic circuit breakers
Wie entscheidet die ECU (Engine control unit), welche ECU (A oder B) arbeiten muss?
ECU operating hours or in case of a failure the ECU with better engine control capability
Wo sind die Pitot and static ports beim DA 40?
Pitot under left wing => Static hinten nach dem Flügel (rear fuselage) => Pitot rohr hat zusätzlich auch noch static ports
Wie werden die Static ports gereinigt?
there are filters in the systems => Pitot is electrically heated
Is there an alternate static valve?
an alternate static valve is in the cabin => used by a failure of the static system
Stall warning?
there is an orifice on the left wing leading edge (red ring) => Activates a horn ( Schlauch ins Cockpit = Trumpet) Horn gets louder when closer the stalling speed => Gibt Unterdruck
Where is the PTT Knopf?
the push to talk button is on the control stick
A warning in G100 is displayed as?
warning = repeating tone and the legend turns red and flash
A caution in G100 is displayed as?
caution is yellow and a single tone
