Acceleration of aircraft carrier take-off | One-dimensional motion | Physics | Khan Academy

TL;DR

The acceleration experienced by a pilot taking off from an aircraft carrier is approximately 33 meters per second squared, more than three times the force of gravity.

Transcript

So I'm curious about how much acceleration does a pilot, or the pilot and the plane, experience when they need to take off from an aircraft carrier? So I looked up a few statistics on the Internet, this right here is a picture of an F/A-18 Hornet right over here. It has a take-off speed of 260 kilometers per hour. If we want that to be a velocity, ... Read More

Key Insights

• ⌛ The take-off velocity and runway length are crucial parameters for calculating the acceleration and time required for take-off.
• 💨 The derived formula for displacement provides a simple way to calculate acceleration using known values of final and initial velocity.
• ✋ The acceleration experienced by a pilot during take-off from an aircraft carrier is significantly higher than the force of gravity.
• ✋ The high acceleration can result in a feeling of increased weight and pressure on the pilot's body.
• 🧑‍✈️ The time needed for a pilot to be catapulted off the flight deck is approximately two seconds.
• 🧑‍✈️ Understanding the physics behind take-off from an aircraft carrier helps explain the intense forces experienced by pilots.
• ❓ The analysis highlights the importance of acceleration and displacement calculations in aviation.

Questions & Answers

Q: What is the take-off velocity of an F/A-18 Hornet from an aircraft carrier?

The take-off velocity of an F/A-18 Hornet is 260 km/h.

Q: How long does it take for a pilot to be catapulted off the flight deck of an aircraft carrier?

It takes a little over two seconds for a pilot to be catapulted off the flight deck, with an acceleration of 33 meters per second squared.

Q: What is the formula for displacement derived in this analysis?

The formula for displacement is the product of the final velocity squared minus the initial velocity squared, divided by 2 times acceleration.

Q: How does the acceleration experienced by a pilot during take-off compare to the force of gravity?

The acceleration experienced by a pilot during take-off is more than three times the force of gravity, equivalent to more than 3 g's.
