c) Sufficient airspace
d) Number of ground staff
Answer: d [Reason:] The other 3 options are the specific aspects on which the site-selection is dependent. The site should be accessible by people easily from different locations, there should be potential for air traffic – flight or passenger and sufficient airspace for airports without obstruction. The ground staff is considered depending on size of airport.
6. Runways are oriented in a direction against the prevailing wind.

a) Wind Butterfly
b) Wind Cycle
c) Wind Star
d) Wind Rose
Answer: d [Reason:] An average date of around 5-10 years of the various components of wind (intensity, duration and direction) of the area is compiled to make a Wind Rose diagram. The entire area of the airport is divided into 16 equal parts at angles of 22.5o. The wind coverage in each of the small quadrants is then studied for the orientation of the runway.
9. Elevation of airport site above MSL is a factor that controls airport size.
Answer: a [Reason:] It is one of the factors. As the elevation increases, the meteorological conditions like air pressure and density reduces. As a result, bigger size of facilities has to be provided.
10. How many type of Fly Rules are there?
Answer: a [Reason:] There are 2 fly rules; the VFR (Visual Flight Rules) and IFR (Instrumental Fly Rules). The VFR allows the aircraft to be operated within reasonable conditions by oneself. In IFR, the operations are entirely controlled by instruments. A flight plan is required in both cases.
