Embraer 190 - Normal Procedures (Sopm)

Explanation
The correct answer is "Verify batteries voltage at or above 22 V" because it is the highest voltage requirement among the given options. This means that the batteries need to have a voltage equal to or greater than 22 V in order to pass the check.

Explanation
The correct answer is to recharge the batteries prior to takeoff, through any AC source. This is because the batteries voltage should be between 21 V and 22 V for ANAC/TCCA certification or between 21 V and 22.5 V for FAA/EASA certification. By recharging the batteries through an AC source, their voltage can be increased to meet the required range for certification. Changing the batteries may not be necessary if they can be recharged to the appropriate voltage level.

Explanation
The Electrical PBIT is a process that is automatically initiated when the airplane is powered by any AC source. It is a diagnostic test that checks the electrical systems of the aircraft. This test takes about 3 minutes to complete, allowing enough time for the system to thoroughly assess the electrical components and ensure they are functioning properly.

Explanation
The Electrical PBIT will be interrupted if the electric hydraulic pump is running because the pump draws power from the electrical system, which can disrupt the PBIT process. Additionally, if AC power is interrupted while the test is running, it can cause a loss of power to the electrical system and interrupt the PBIT. Finally, cycling the FLIGHT CONTROLS MODE Panel switches can also interrupt the PBIT as it can cause a disruption in the electrical signals being sent to the flight controls.

Explanation
The correct answer is 2 Master Warning, 6 overhead lights and 7 EICAS indications, 15 lights total. This is because the question mentions pressing and holding the TEST button, which would activate the warning lights and indications. The total number of lights mentioned in the question is 17, but this includes the "Press and hold the TEST button" instruction, which is not a light indication. Therefore, the correct answer is the option that subtracts the "Press and hold the TEST button" instruction, resulting in a total of 15 lights.

Explanation
The correct answer is 0.5%. The N1 target indication on the EICAS must be equivalent to the N1 target indication available via performance calculation. The difference between N1 given by FADEC (indicated on EICAS) and the computed value is zero or this difference is positive and lower than or equal to 0.5%.

Explanation
If the flight director is inoperative, the pilot should rotate the airplane to a nose-up angle of 18°. This means that the pilot should adjust the pitch of the aircraft to raise the nose by 18° relative to the horizon. This action is necessary to maintain a safe and controlled ascent or climb in the absence of guidance from the flight director.

Explanation
To prevent electrical power interruptions, it is recommended to wait 10 seconds after the GPU button is pushed in or after the APU is stabilized to shutdown the remaining engine. This waiting period allows for a smooth transition and ensures that all systems are properly synchronized before shutting down the remaining engine. It helps to avoid any sudden power fluctuations or interruptions that could potentially damage the electrical systems.

Explanation
The APU BLEED valve will supply bleed air for both PACKS operation during takeoff until 500 ft. This means that the APU BLEED valve will continue to provide bleed air to the packs, which are responsible for cooling and pressurizing the aircraft cabin, until the aircraft reaches an altitude of 500 ft. At this point, the packs will switch to another source of bleed air, such as engine bleed air.

Explanation
If the APU BLEED is unavailable, it means that the packs, which are responsible for providing air conditioning and pressurization in the aircraft, will not be able to operate. In this case, the packs will remain off until the aircraft reaches 500 ft above ground level (AGL). This is because at this altitude, the aircraft has already gained a sufficient amount of airspeed and the airflow around the aircraft is enough to provide adequate cooling and pressurization without the need for the packs.
