How would you weigh a plane without a scale?

The question of how to weigh a plane without a scale may seem like an impossible task at first glance. However, there are several ways to approach this problem, and the key to answering this question in a job interview is to demonstrate your ability to think creatively and problem-solve in a challenging situation.

One possible approach to weighing a plane without a scale would be to use mathematical calculations based on the known weight of certain components of the plane. For example, you could calculate the weight of the fuel in the plane by measuring the volume of the fuel tanks and using the known density of the type of fuel being used. Similarly, you could calculate the weight of the passengers and cargo by using average weights for each category and adding them together.

Another possible approach would be to use a hydraulic lift system to measure the force required to lift the plane off the ground. This approach would involve measuring the pressure exerted by the hydraulic system as it lifts the plane and using that data to calculate the weight of the plane.

Another method could be to use a combination of GPS and accelerometer data to estimate the weight of the plane. This would involve measuring the acceleration and speed of the plane during takeoff and using that data along with the known properties of the plane to calculate its weight.

Finally, you could also consider using a displacement method to weigh the plane. This would involve filling a tank with water and then submerging the plane in the tank, measuring the volume of water displaced by the plane, and using that data to calculate its weight.

In any of these approaches, it is important to recognize that there may be limitations and uncertainties in the data and methods used, and to be transparent about these limitations when presenting your solution. Additionally, it is important to demonstrate your ability to communicate complex ideas clearly and concisely, and to show that you are comfortable working with technical concepts and data.

In summary, when answering the question of how to weigh a plane without a scale in a job interview, it is important to approach the problem creatively and demonstrate your problem-solving skills. By presenting a well-reasoned and thoughtful solution, you can show your potential employer that you are a skilled and resourceful candidate who is able to tackle complex challenges.
