Marino - Otter-AOC flash cards
(500 cards)
Prop De-IceHow long until the entire cycle is complete
2 minutes and 16 seconds (34 * 4)
Prop-DeIceCycling the deice switch will…
Switch to the next element in the sequence(Left Outter, left inner, right outter, right inner)
Prop De-Icedeice will stop when the switch is turned off or…
When the oil pressure is below 40psi (prevents overheating when the prop is not turning)
Prop De-IceAfter engine failure, will the prop de-ice system still allocate time to the failed side
Yes, although the failed side is not receiving power, the timer will still allocate time to it.
BootsHow are the boots of the horizontal stab different than the wings (structurally)
There is a nylon cap between the horizontal stabilizer and the stabilizer boot as reinforcement from ice from the wing colliding with the stab.
Dual Pressure SwitchWhat will happen with cabin heat in AUTO and pressure below 25psi
The dual pressure switch will stop further opening of the hot air valve.
Dual Pressure SwitchWhat will happen with cabin heat in AUTO and the pressure falls below 20psi
Hot air valve will close
What is the function of the ejector near the horiz stab?
The ejector uses bleed air to create a vacuum, holding the boots tight to the leading edge of the wing and hoz stab.
What is the function of the distribution valve?
The three valves (one for each wing plus for the stab) takes signal from the timer to switch each boot between pressure from the bleed air (inflate) and suction from the ejector (deflate).
What is the boot timing for FAST and SLOW
One minute cycles (each boot) and Three minutes cycles.
What is the purpose of the valve heater
To prevent freezing of bleed air condensation in the distribution valve. Remember the air condenses through a heat exchanger before it gets to the boots.
What are inflation times for the wing and stab boots
5 seconds and 3 seconds
What is the dwell time in FAST and SLOW
44 and 164 seconds
What is the nulling function of the boots
When turned off, then on the boots will start the cycle of the next boot in the sequence
What does the stab boot lights indicate
The pressure is being supplied to the boots, it does not insure operation
Stab boot activation with flapsHow many times will the stab boots inflate with flaps 5-12 degrees
Twice, only with bleeds on and boots are off
Stab boot activation with flapsHow many times will the stab boots inflate with >17 degrees
An additional two, only with bleeds on and boots are off
What will happend when using the wipers >100 kts
They may not park and possibly pop the circuit breaker
What are the limitations on windshield heat
Never run it on the ground unless taxi before takeoff into icing conditions.Must be left on in icing conditions
Why should you avoid anti-collision lights on with the boots on auto
the strobe can interfere with the boot’s timer
What are the 6 operating limitations of the de-ice system
- All de-ice systems must be fully operative2. Boots must be operated prior to flap extension3. Ng MUST be above 75% Ng4. Do not extend flaps >10 degrees5. Extend intake deflectors in icing6. Intentional flight into Severe icing is prohibited
What is an qualified non-crewmember?
Has completed ditching training and all applicable training specified in 209-124Scientists comply as long as the PI vouches that they have ditching training and is familiar with 209-124.
What is an Air Crewmember?
Able to perform emergency duties in flight, FDIFT
What are the limitations with flight observers (media, VIP)?
Can only be on 1 flight within a 4 month period limited to 3 flights per year. Must complete online training specified in 209-124.
