Problem-Solving Exercise 1
1. In your own words, explain what density altitude is and how it affects your airplane. Density altitude, or "Pressure Altitude", is the density of air given as a height above Mean Sea Level (MSL). Density altitude affects the wings ability to create lift, the aircrafts propeller to create thrust and the power output of the engine.
2. In your own words, explain the theory of lift and what basic laws are involved.
In my opinion lift can be explained by a combination of Newton's 1st, 2nd and 3rd Laws and Bernoulli’s principle. Newton's 1st Law, in this context, is basically air that is originally at rest is accelerated into motion, there is a force acting on it. Newton’s 2nd Law relates, for more lift the wing can either divert more air (mass) or increase its downward velocity. Newton’s 3rd Law, for a wing to generate lift a wing must do something to the air. What the wing does to the air is the action while lift is the reaction. Bernoulli's principle is basically, a wing generates lift because the air goes faster over the top creating a region of low pressure, high pressure chases low pressure and thus creates lift.
3. Explain in detail how the airspeed indicator works. The Airspeed indicator works by air being forced into the pitot tube measuring and promptly indicating the difference between pitot and static pressure. These two pressures are equal when the aircraft is parked on the ground in calm air. When the aircraft moves through the air, the pressure on the pitot line becomes greater than the pressure in the static lines. This difference in pressure is registered by the airspeed pointer on the face of the instrument, which is calibrated in miles per hour, knots, or both.
4. Discuss the 2 gyroscopic principles and how they relate to your aircraft instruments.
The two gyroscopic principles or properties are: rigidity and precession. Rigidity refers to the principle that a gyroscope remains in a fixed
