How do you carry out a Manual Start?
MANUAL start:
1) PMS set to MANUAL.
2) Booster pumps ON and moves the STARTER switch to MAN.
3) When the oil P rises the ignition is set to IGN.
4) Move the throttle slowly forward until the ITT increases. As the ITT peak moves the throttle slowly to idle.
5) When the engine reach idle (Ng (67% ± 7%), with the throttle above the idle stop, the pilot must return the starter, ignition and fuel pump switches to AUTO.
What is a Manual Start?
MANUAL START - Throttle manually controls the rate of increase of fuel flow to the engine and therefore the rate of rise of the ITT. If the throttle is moved forward too quickly, the ITT could exceed limits or the engine could surge. Shut-down the engine if the ITT fails to rise (no light up), exceeds limits or if the Ng stabilizes below idle.
Why 2 peaks on ITT?
First peak is to test the integrity of the FCMC, while the second peak is the actual ITT of the aircraft.
How do you know where your fire is occurring when the captions on the DWP and MFD appears?
- White smoke (electrical fire)
- Black smoke (fire caused by fuel)
How does the Fire Alert System work?
If there is a fire or overheat in the engine compartment, red FIRE warnings are given in both cockpits on the DWP and MFD. A fire around the engine expands the gas in the fire detector element. The gas pressure increases and operates a switch in the detector to complete a circuit and operates the fire detection relay.
2 gas-filled tube to sense temperature attached to outercase of enginem, powered by BATT BUS
Where the are the FIRE OVERHEAT DETECTORS found?
- No.1 found in the hot section of gas generator case.
- No.2 found in accessory gearbox
Red FIRE warning captions are shown on the front and rear DWP and MFD.
Grey FIRE 1 ALRT/FIRE 2 ALRT captions on MFD.
What is the oil T and Ps green, amber and red range in right MFD and what are the indications?
TEMPERATURE Green - Oil temperature from 10 to 105 degrees Amber “OIL TEMP” cap on MFD − Oil temperature > 105 °C (221 °F − Oil temperature < 10 °C (50 °F). Red “OIL TEMP” cap on MFD − Oil temperature > 110 °C (230 °F) − Oil temperature < -40 °C (-40 °F) − Oil temperature > 105 °C (221 °F) for longer than 10 minutes.
PRESSURE
Green - 90 to 125 psi
Amber
“OIL PRESS” cap on MFD
− Oil pressure < 6,21 bar (90 psi) for longer than 10s with engine Ng >= 72%
− Oil pressure < 4,83 bar (70 psi) for longer than 10s
− Oil pressure > 8,62 bar (125 psi) for longer than 55s
− Oil pressure > 8,96 bar (130 psi)
Red
“OIL PRESS” cap on MFD
“OIL” cap on DWP
− Oil pressure < 4,83 bar (70 psi) for longer than 20s
− Oil pressure > 8,96 bar (130 psi) for longer than 20s
− Oil pressure > 13,72 bar (199 psi)
What are the PMS manual captions?
PMS MANUAL on MFD Alerts and ENG page

Definition of chicken fuel.
‘Chicken Fuel’ is the minimum fuel computed from the furthest point of the navigation route, where the aircrew must initiate the chicken fuel recovery profile when it is assessed that he/she will go below ‘Chicken Fuel’ before reaching the furthest point.
(SOP 8-1 – Navigation)
Chicken fuel is calculated from the furthest point directly back to Pearce.
(SSG Chapter 25 – MEDIUM LEVEL NAVIGATION 4.1.3 Pg 5)
Number of propellers blades on the PC21.
Five-bladed, variable pitch, feathering, constant speed.
Definition of Min Power and Min Practicable Power.
Minimum Power: Power setting to maintain 140 – 160 kts (25%-35% TQ) after the initial CAPS/FRC actions.
Minimum Practicable Power: Power setting to reduce to stabilise the nature of the engine problem. If the affected system returns to within ops limits at a particular setting, that power setting should be used for recovery.
What is the sequence of landing gear retract and extension?
Retract: Right >Left> Nose
Extend: Nose> Left > right
Where is the WOW switch located on the aircraft?
Main landing gear and nose landing gear itself. Total 3 WOW switches.
Why does the nose wheel have more pressure than the Main wheels?
Nose wheel to support the weight of the engine,
Main wheels to absorb the impact on landing
Why does the SKID DWP caption goes out when GPU connected?
The GPU supplies power to the BATT BUS, which supplies power to the TRIM/AIL PWR switch.
How long for the flaps to come down?
UP to T/O: 4-5sec
T/O to LDG: 4-5sec
How long for gears to come down?
Gears extension: 5 sec
retraction: 4 sec
How long for Airbrakes to come down?
Airbrake retract/extend: 2 sec
What are the angle ranges for rudder & elevator trim?
Elevator trim max deflection: 3.5 nose up and -7.5 nose down
Rudder trim: -4 nose left, +19(?) nose right
What are the trim timing limits?
Yaw trim timing limits: minimum 19s, max 23s
Roll trim timing limits: min 17s, max 21s
What is the trim offset on the rudder when the aircraft is on the ground? (sect 9.25)
When in the on-ground mode the TAD sets the rudder trim to the fixed take-off position of 7.5° nose right
Purpose of winglets on the PC21.
Reduces wingtip vortices, reducing induced drag.
How many circuit breakers are in the front cockpit and what are they?
- PFD front, IRS primary power
SFD front, Air intake
