C01 - Introduction Flashcards
What is the horizontal and vertical distance used in Aviation?
- Nautical Miles (nm).
- Feet (ft).
How much is 1nm in m?
1852m.
How much is 1m in ft?
3.28ft.
What is the horizontal and vertical speed used in Aviation?
- Knots (kt).
- Feet per minute (fpm).
What is the equation for kt to m/s (2)?
- kt x (1852 ÷ 3600).
- m/s = 0.5144 x kt.
What is the equation for m/s to kt (2)?
- m/s x (3600 ÷ 1852).
- kt = 1.944 x m/s.
What is the equation for rate of climb/descent?
60 x 3.28ft.
Define Acceleration?
The rate of change of Velocity.
What is the formula for Acceleration?
F = M x A.
Define Momentum?
The product of an object’s Mass multiplied by its Velocity.
What is the conversion rate for kg to lb?
1kg = 2.205lb.
What is the conversion rate for lb to kg?
1lb = 0.454kg.
What is the measurement of Force?
Newtons (N).
What is the Earth’s gravitational force?
9.81m/s².
If an Aircraft weighs 60,000kg, what is the approximate total weight including the Earth’s gravitational force?
600,000N (multiple the kg by 10m/s²).
What is the measurement of Energy?
Joules (J).
Name two types of Energy?
- Kinetic.
- Pressure.
Define Kinetic Energy?
The Energy which a Mass possesses due to its relative motion.
What is the formula for Kinetic Energy?
½ mV².
Define Pressure Energy?
The Energy that make up a volume of air.
Define Work and its measurement (2)?
- When Energy is converted from one form to another.
- Measured in Joules.
What is the formula for Work?
Force x Distance.
Define Power and its measurement (2)?
- The rate of doing Work.
- Measured in Watts.
What is the formula for Power?
Force x Speed.
What is Newton’s First Law?
A body will remain at rest or in uniform motion unless acted upon by an external force.
What is Newton’s Second Law?
Force is equal to Mass times Acceleration (F = MA).
What is Newton’s Third Law?
For every action there is an equal and opposite reaction.
What are the four forces acting on an Aircraft?
- Lift.
- Weight.
- Thrust.
- Drag.
