23
Q

An AMBER light begins flashing on the Left Hand AI during flight. What does this indicate and what should you do?

Study These Flashcards
A

This indicates electrical power loss to the AI. The STBY PWR button should be pressed to operate the AI on its internal battery.

24
Indications: Excessive rev drop on magneto check (over 150 RPM) Cause? Your Actions?
Cause: Fouled spark plugs, faulty spark plugs or ignition system. Actions: If condition persists after clearing run, report fault.
25
Indications: High oil temperature Cause? Your Actions?
Cause: Thermostatic valve malfunction, cooler coring, blocked cooler air intake. Actions: Increase airflow through cooler without increasing engine power, or reduce power. Report fault.
26
What does the flag on the turn and balance indicator indicate when it is visible?
There is no power to the gyroscope
27
Indications: Excessive fluctuation of the Fuel Flow gauge Cause? Your Actions?
Cause: Air in the engine fuel system (vapour lock). Actions: Select LOW boost to purge engine fuel system of air. If no improvement is noticed, select EMERG boost. CAUTION: Throttle idle before selecting EMERG boost to prevent a rich cut.
28
Indications: Oil temperature gauge fluctuating. Cause?
Cause: Electrical connection faulty or faulty gauge. Possible impending engine failure.
29
Indications: Slow or fluctuating reading on the Oil Pressure Gauge. Cause?
Cause: Faulty oil pressure gauge or air in the line from engine to instrument. Possible impending engine failure
30
What does 'ON' on the transponder represent?
Mode A, the unit replies to interrogations by transmitting the pre selected code.
31
What are the following Oil Temperature limits: 1. Normal in-flight 2. Caution in-flight 3. Maximum
1. 24 - 95 degrees 2. 95 - 115 degrees 3. 115 degrees
32
What should you do before changing the transponder code?
Turn transponder to STBY to prevent transmitting on another code (an emergency code for example)
33
How long can the electric AI operate for on its backup internal battery?
Up to 1 hour after electrical power is lost.
34
Indications: Vibration, especially apparent during propeller pitch change. Cause? Your Actions?
Cause: Out of balance propeller or propeller malfunction Actions: Reduce power and report fault
35
What are the following ASI ranges? 1. Maximum (red line) 2. Full flap range (white arc) 3. Normal range (green arc) 4. Smooth air only (yellow arc)
1. 207 KIAS 2. 50 - 91 KIAS 3. 59 - 147 KIAS 4. 147 - 207 KIAS
36
Indications: High CHT Cause? Your Actions?
Cause: Lean mixture. Operation for excessive periods at full throttle or high power settings. Actions: Select full rich, reduce power and/or increase airspeed (attitude change)
37
What are the roll indications on the AI?
0, 10, 20, 30, 45, 60, and 90 degrees
38
Indications: Rough running Cause? Your Actions?
Cause: Rich mixture for altitude or blocked injectors. Actions: a) Lean mixture for power and altitude b) Report fault
39
What are the Tachometer limits for: 1. Idle 2. Normal In-flight 3. Takeoff and climb
1. 600 - 800 RPM 2. 600 - 2800 RPM 3. 2700 - 2800 RPM
40
What is an overswing?
A transient rise in engine RPM to between 2800 RPM and 3000 RPM for less than 10 seconds, followed by a return to normal RPM.
41
Indications: Mixture control stiff or jamming Cause? Your Actions?
Cause: Mixture control selector requires attention Actions: Report fault Check friction nut.
42
Indications: Low Boost / RPM Cause? Your Actions?
Cause: AIrcraft not into wind. Engine not developing full power. Propeller blades not in fine pitch. Actions: a) Turn aircraft into wind b) Report fault if condition exists after propeller pitch change check and full engine run up.
43
What are the following ranges on the Fuel Flow gauge? 1. Normal 2. Maximum
1. 42 - 107 lb/hr | 2. 107 lb/hr
44
Which instrument in the CT4B is driven by an engine driven vacuum pump?
The right hand AI.
45
What pitch reference marks are there on the AI?
Every 2 degrees up to 10 degrees. Then 5 degrees thereafter up to 25 degrees.
46
Indications: Low, no, or fluctuating reading on the CHT gauge. Cause? Your Actions?
Cause: Faulty gauge or electrical lead connection. Faulty fuel injector in the No. 4 cylinder.
47
On the Fuel Contents Indicating System (Electric Fuel Gauge), what does the yellow and red lights indicate?
``` Yellow = That tank has 1/4 fuel remaining Red = That tank has 1/8 fuel remaining ```
