## What is the thrust to weight ratio of a Cessna 172?

A good estimate for a personal aircraft thrust requirement would be more like 25% of aircraft weight, and remember, the “ton” of Cessna includes fuel and pilot too! 213 kg thrust/909 kg weight = 23.3 % thrust to weight ratio.

## What is a good thrust to weight ratio?

Acceptable Thrust to weight(rocket and installed motors) ratio: A minimum ratio of 5:1 is typically required. This can be as low as 3:1 at the RSO’s discretion.

To calculate wing loading, divide the mass of the bird or plane by the total area of the upper surface of its wings: wing loading = body mass (kg)/wing area (m2).

Therefore, a plane with lower wing loading will be able to take off and land at a lower speed (or be able to take off with a greater load). It will also be able to turn faster. Wing loading for birds is generally between 1 to 20 kg/m2.

## How much thrust does it take to lift a human?

Yes, lift is nothing but the force in the upward direction. So to keep a 150 pound person aloft, you need a lift of 150 pounds (150 pound-force).

## What plane has the highest thrust to weight ratio?

J85
For many years, the J85 had the highest thrust-to-weight ratio (8:1) of any jet engine in aviation.

## What is the thrust to weight ratio of an aircraft?

For aircraft, the quoted thrust-to-weight ratio is often the maximum static thrust at sea-level divided by the maximum takeoff weight. In cruising flight, the thrust-to-weight ratio of an aircraft is the inverse of the lift-to-drag ratio because thrust is the opposite of drag, and weight is the opposite of lift.

## Can a plane take off with less thrust than its weight?

A plane can take off even if the thrust is less than its weight: if the lift to drag ratio is greater than 1, the thrust to weight ratio can be less than 1, i.e. less thrust is needed to lift the plane off the ground than the weight of the plane. For propeller-driven aircraft, the thrust-to-weight ratio can be calculated as follows:
