LR45 – General Information
Turbofan engine – TFE 731-20 engines (3500# thrust @ sea level)\
Hydraulics – 2 engine driven systems / redundant and situational – if in doubt take the breaks over
reversers or flaps – operates spoilers, spoilerons and flaps – everything else is mechanical
Brake by wire and Steer by wire systems – Brakes are pretty beefy
Electrical – Generators (no inverters) - components handle conversion of power themselves, Alternators
only used for windshield heat
Glass Cockpit – utilizes 4 MFD’s (info interchangeable) / EICAS normally on MFD #2 – can also be
shifted to RMU in case of failures
Not certified for ditching. Doesn’t float well.
Unpressurized areas – nose, fuel and tail
Wings – group leading edges – fixed to keep laminar flow and ailerons effective at higher AOA /
vortilons (vertical edges on wings) prevent lateral flow at high AOA / stall strips (sharp triangles) delay
separation at high AOA and allows for better handling at low speeds
Tail – Delta Fins – enhances stability and decreases Dutch roll / also provides static discharge
Doors – 2 piece clam shell – open top first (6 pins) then lower door (4 pins) / CAS messages for Entry
Door Pin –on ground only, Entry Door – Inflight
Top Door is also Emergency exit / Emergency hatch on other side (drop straight to ground 5-6’ – watch
triangles or get cut)
Fuel – gravity fill and single point on fuselage only (no fuel caps on wings)
Aft Baggage can be heated – light is also Hot Bus Item (don’t forget to turn it off)
Anything Magenta means pilot selected – White data refers to FMS – Green data refers to RMU
Static Wicks – 4 may be missing
Most inboard on winglet, inboard on delta fin, inboard on elevator, aft on vertical stabilizer

Flight Instruments
The Primus 1000 Avionics System (Honeywell) – the IC600 flight guidance computer
Dual IC600’s, dual air data computers (ADC), the Primus Weather Radar system, and the Honeywell
Primus II integrated radio system (RMU).
The Primus 1000 Electronic Flight Instrument System (EFIS) – 4 Display Units (DU’s) driven by two
Signal Generators (SG’s) which reside within the IC’s.
IC#1 – runs DU1 and DU2
IC#2 – runs DU3 and DU4
Data Acquisition Units
IC’s receive data from the DAU’s, ADC’s, AHRS’s, Navigation systems, FMS’s, autopilot and other
systems to generate the information displayed on the EFIS system.
Airspeed Display has several bugs and trend indicators. These make it easy once you figure them out.
Lead them slightly.
Speed Trend – pink bar on right side – shows where airspeed will be in 10 seconds
Overspeed Indicator – red bar left side at top
Low Airspeed Awareness – red bar left side bottom
Mach Indicator – shown at bottom of airspeed tape
Set bugs by using speed knob
Abnormal Conditions – digits amber when overspeed imminent / digits red during overspeed
Comparison Alert – IAS in amber – when speeds ±5 kts, (.1 Mach) – indicates ADC problem
- red X indicates ADC failure
Altitude Display – Right tape on PFD
Alt. Select Digital Readout – set through ASEL knob (top center panel)
FD/AP won’t level off if GS is green (captured)
Double Chevron – for 1000’s / single chevron – for 500’s
RA – detects low altitude awareness (brown box at bottom of tape)
Trend Bug – magenta left side of tape – where you will be in 6 seconds
Alt Bug – won’t show if off scale
Comparison Alert – ALT in amber – when ADC’s are outside of 200’
Red X – ADC failure
Baro Indication – toggles between inches and millibars / set with BARO SET knob (bottom right
