major weather hazards that cause a number of aircraft accidents. It is a hazard that can snowball out of control and cause problems such as reduce aircraft efficiency by increasing weight‚ reduce lift‚ decrease thrust and increase drag. These effects can cause the aircraft to increase stalling speed or cause the aircraft to force downward in flight. Over the years‚ aircraft engines and airframes have changed dramatically. Modern day aircraft are aerodynamically less accepting of airfoil

be found on cars‚ metal pipes‚ aircrafts and anywhere with iron‚ copper and aluminium. Corrosion can be concentrated locally to form a split or crack‚ or it can extend across a wide area which causes corroding on surfaces. Because corrosion is a diffusion-controlled process‚ it occurs mainly on exposed surfaces. Besides costing millions of dollars in aircraft inspections and repair work‚ corrosion can lead to massive safety risks if it is left untreated. Aircraft mechanics and technicians have

TUTORIAL1 WITH INFORMATION TO SOLUTIONS 1. For most products‚ higher prices result in a decreased demand‚ whereas lower prices result in an increased demand. Let d = annual demand for a product in units p = price per unit Assume that firm accepts the following price-demand relationship as being realistic: d = 800 – 10p where p must be between $ 20 and $70. a. How many units can the firm sell at the $ 20 per-unit price? At the $ 70 per-unit price?
