Landing gear limiting speed
Less than 130 kts
What to do in a landing gear malfunction
Follow the checklist in FRC
Landing gear warning horn
Power below 12” of MAP (manifold air pressure) and gear selector up
Flap lever is moved beyond approach flaps and power
For ground towing what must be checked
Oloe collar must be checked as removed before flight
Tell tale flag is attached to pitot to increase visibility to collar if fitted
When in the right hand seat you must keep feet clear of?
Rudder and breaks
Engine oil
Wet sump type
Pressure range 25 to 100 psi
Company minimum oil to fly
7Qts
If oil pressure is below 25 psi?
This is hazardous to engine operation
What fuel type?
100 or 100LL Avgas
Total fuel and totals for each tanks
Total = 720L
Inboard = 420L
Outboard = 300L
What two types of fuel indicator?
Fuel flow indicator (most accurate)
Fuel float
What will happen if you run inner or outer tanks dry?
Ultimately it will cause the engine to stop
What will happen when fuel level is low?
Before the fuel LP light on BWS will illuminate and engine will cough and splutter
Key is to monitor the balancing carefully and regularly
Maximum RPM
2575

45 kts
Awareness of what is essential?
Awareness of high ground
Voltage range
24 - 30V
Current
+ve (positive) rate if change
If pneumatic system fails what do you not use?
Auto pilot as it relies on gyros
Gyro pressure gauge
4.3 - 6.1”
What are icing conditions defined as?
10°c or less and visible signs of moisture
How does de icing boot work?
Boot solenoid valve opens, suppressing the suction and sends air to all the boots and cuts off air to co pilot gyros
De icing considerations
Airframe noise may be heard as rhe ice detaches from the airframe / propellers
What may be interruped by using de icing boot?
Co pilot gyro instrument pressure may be interrupted during operation
Panther anti ice
Heated pitot heads
Heated windscreen
Propeller mats
TAS is only useful for?
Transponder equipped aircraft only
Actions on warning of “traffic, traffic”?
CRM with captain
