This force slows an aircraft down in the air.
what is drag?
This ratio compares lift to drag.
What is lift-to-drag ratio?
this force pulls the aircraft to the ground.
what is gravity/weight?
This force moves an aircraft forward through the air.
what is thrust?
This part of the aircraft mainly creates lift.
what are wings?
Reducing this helps an aircraft fly faster and more efficiently.
what is drag?
This must be greater than weight for an aircraft to take off.
what is lift?
This measures how efficiently an aircraft uses fuel.
What is fuel efficiency?
Lighter aircraft improve this phase of flight the most.
What is takeoff performance?
This increases when an engine produces more thrust.
What is speed or climb rate?
Flying higher usually reduces this force.
What is air resistance (drag)?
this force keeps a aircraft in the air.
what is lift?
The shape of an aircraft that reduces drag is called this.
What is aerodynamics?
Materials like carbon fiber help reduce this.
What is aircraft weight?
This helps an aircraft climb more quickly.
what is thrust
This altitude region often improves fuel efficiency due to thinner air.
What is cruising altitude?
This law explains how force equals mass times acceleration in flight.
What is Newton’s Second Law?
This angle between the wing and airflow affects lift.
What is angle of attack?
This ratio is key for long-distance efficiency in aircraft.
What is lift-to-drag ratio?
Increasing this can improve takeoff and climb performance.
What is engine power (thrust)?
This is the point where lift equals weight and thrust equals drag.
What is steady level flight?
This happens when lift is no longer enough to support the aircraft.
What is a stall?
This design feature reduces drag caused by wingtip vortices.
What are winglets?
This performance limit is reached when an aircraft cannot climb higher.
What is service ceiling?
This combines lift, drag, thrust, and weight in flight analysis.
What is aircraft performance (forces in equilibrium/dynamics)?
