Question 1
Engine anti-ice systems must be on for taxi and takeoff when in visible moisture at what temperature?
Correct Answer:
5 degrees C or colder
Explanation:
Engine anti-ice is required during taxi and takeoff when visible moisture is present and the ambient air temperature is 5°C or colder. The reason is that at or below this temperature range, supercooled water droplets in visible moisture can freeze on contact with the engine inlets, forming ice that blocks airflow and reduces thrust or even leads to engine damage. Activating the anti-ice system warms the inlet and prevents ice buildup before it starts. If the temperature is warmer than 5°C, the icing risk in typical visible moisture conditions is much lower, so the rule doesn’t require anti-ice for taxi/takeoff in that case.
Question 2
In an engine failure during landing configuration, what is the recommended action regarding thrust?
Correct Answer:
Thrust (operating engine) AS REQUIRED
Explanation:
When one engine fails during landing configuration, you manage energy by setting the thrust on the remaining engine to whatever level is required to hold the correct approach speed and descent profile. This ensures you have enough airspeed and control authority to safely reach the runway, and it leaves you with the option to go around if stability or glide path cannot be maintained. Keeping the operating engine at idle would likely cause you to slow too much and risk a stall, while pushing it to maximum isn’t needed for a normal approach and could create unnecessary asymmetry and drag. So you apply thrust on the operating engine as required to sustain the approach and maintain safe energy management.
Question 3
Which annunciator indicates a clogged fuel filter?
Correct Answer:
L or R F FLTR BYPASS annunciator
Explanation:
In the Beechjet 400A fuel system, a clogged fuel filter is indicated by the fuel filter bypass indicator on the left or right side. When a filter becomes sufficiently restricted, the bypass valve opens to maintain fuel flow, and the corresponding FUEL FILTER BYPASS light comes on. This tells you the filter is likely clogged and needs service or replacement. Other lights shown—low fuel level, generator off, or low fuel pump—relate to different systems (quantity, electrical generation, or pump performance) and do not indicate a clogged filter.
Question 4
If No.1 inverter fails, what does No.2 inverter do?
Correct Answer:
Transfers power to the primary buses leaving the secondary buses powerless.
Explanation:
Redundancy in the inverter power system is designed to keep essential aircraft loads alive if one inverter fails. When the first inverter goes out, the second inverter automatically takes over the primary buses to maintain power for the critical avionics and flight-control systems. The secondary buses are left powerless because the system prioritizes the primary (essential) loads and isolates the nonessential buses to prevent overloading the remaining inverter. This is why the surviving inverter transfers power to the primary buses rather than continuing to power the secondary buses or shutting down the whole system.
Question 5
In a false start, what is the first action you should take?
Correct Answer:
Move the thrust lever to CUTOFF.
Explanation:
During a false start the immediate goal is to stop fuel flow and prevent the engine from accelerating further. The quickest and most effective way to do that on the Beechjet 400A is to move the thrust lever to CUTOFF. This action shuts off fuel to the engine, halting the start sequence and allowing the engine to decelerate safely. Turning the ignition off or pressing the engine start disengage button aren’t the primary steps to halt the start, and delaying fuel cutoff can allow the compressor to accelerate toward surge. After the fuel is cut, you would monitor engine indications and follow the SOP, potentially motoring the engine briefly if required to purge fuel, before attempting a restart.
