Two alternators are used as a safety measure. The probability of both alternator failing are very minimal. Many planes use redundant systems.

A certain airplane has two independent alternators to provide electrical power The probability that a given alternator will fail on a 1-hour flight is 02 What is the probability that a both will fail?

If the probability of an event is 0.02, then the probability of two such events occurring is 0.022 or 0.0004.

There is insufficient information for us to answer this question. Please edit the question to include more context or relevant information. It would be useful to know the following:The failure rate of each alternator;Which of the two alternators is the "given" one.


How are airplane battery's charged?

The same way a car battery is charged, via alternators. An airplane can have up to eight extremely strong engines that can provide tremendous amount of torque for very strong alternators to charge the batteries.

How is wind energy collected from nature?

Wind energy is collected by the use of turbines or windmills. The blades on these windmills are designed like airplane wings, and they produce 'lift' that turns the blades. The blades are connected to electric alternators, generating electrical energy for use in home and industry.


What in the independent variable in a paper airplane experiment?

In a paper airplane experiment, the independent variable is the factor that is being deliberately manipulated or changed by the researcher. This could be the type of paper used, the design of the paper airplane, the angle of launch, or the force applied when throwing the airplane.


WHAT IS THE INDEPENDENT VARIABLE OF A PAPER AIRPLANE?

The independent variable of a paper airplane experiment is the factor that is intentionally changed or manipulated to observe its effect on the airplane's performance. Common examples include the wing design, the weight of the paper, or the folding technique used. By varying these factors, one can assess how they influence flight distance, flight time, or stability.

What frequency does an airplane generator use?

An airplane generator typically operates at a frequency of 400 Hz. This high frequency is used to provide a more compact and lightweight design for the electrical system on aircraft.
