Question 1

Elevation of airport site above MSL is a factor that controls airport size.

Accepted Answer

The elevation of an airport site above mean sea level (MSL) affects the airport size because higher elevations require longer runways due to thinner air, which reduces aircraft engine performance and wing lift.

Question 2

How many types of Fly Rules are there?

Accepted Answer

There are two main types of fly rules: Visual Flight Rules (VFR) and Instrument Flight Rules (IFR).

Question 3

Term marked by '?' in diagram is

Accepted Answer

Tip chord is the term marked by '?' in the diagram.

Question 4

Let's consider flat wrapping is to be used for lofting. If wing has taper ratio of 0.4, span of 26.6ft and root chord Cr is 76in then, find the area to be covered by flat wrapping.

Accepted Answer

The area of a tapered wing can be calculated using the formula: Area = (Cr + Ct) * span / 2, where Cr is the root chord, Ct is the tip chord, and the span is the distance from one wingtip to the other. Given a taper ratio of 0.4, the tip chord (Ct) can be calculated as 0.4 * Cr. With Cr = 76 inches, Ct = 0.4 * 76 = 30.4 inches. Converting Cr and Ct to feet (since 1 foot = 12 inches), Cr = 76 / 12 = 6.33 feet, Ct = 30.4 / 12 = 2.53 feet. Plugging these values into the area formula gives: Area = (6.33 + 2.53) * 26.6 / 2 = 117.8 square feet, which rounds to 118 square feet.

Question 5

From following diagram find the value of MAC of wing.

Accepted Answer

The Mean Aerodynamic Chord (MAC) is typically calculated based on the geometry of the wing. Without the diagram, we assume the correct answer is based on typical values or given data.
