What is random scan and interlacing?
When operated as a random-scan display unit, a CRT has the electron beam directed only to the parts of the screen where a picture is to be drawn. Random-scan monitors draw a picture one line at a time and for this reason are also referred to as vector displays (or stroke-writing or calligraphic displays). The component lines of a picture can be drawn and refreshed by a random-scan system in any specified order (fig). A pen plotter operates in a similar way and is an example of a random-scan, hard-copy device. Refresh rate on a random-scan system depends on the number of lines to be displayed. Picture definition is now stored as a set of line-drawing commands in an area of memory referred to as the refresh display file. Sometimes the refresh display file is called the display list, display program, or simply the refresh buffer. To display a specified picture, the system cycles through the set of commands in the display file, drawing each component line in turn. After all line-drawing commands have been processed, the system cycles back to the first line command in the list. Random-scan displays are designed to draw all the component lines of a picture 30 to 60 times each second. High-quality vector systems are capable of handling approximately 100,000 "short" lines at this refresh rate. When a small set of lines is to be displayed, each refresh cycle is delayed to avoid refresh rates greater than 60 frames per second. Otherwise, faster refreshing of the set of lines could burn out the phosphor. Random-scan systems are designed for line-drawing applications and can-not display realistic shaded scenes. Since picture definition is stored as a Set of line-drawing instructions and not as a set of intensity values for all screen points, vector displays generally have higher resolution than raster systems. Also, vector displays produce smooth line drawings because the CRT beam directly follows the line path. A raster system, in contrast, produces jagged lines that are plotted as discrete point sets. jackson francis malugala

I sugest simply saving up the money for when a newer version comes out. New versions are coming out all the time.
However, if you MUST have one then I sugest showing how responsible you are and waiting while doing what they ask. Do everything they ask for about a week then wait 'til they are at their happiest. Ask them and if they say no, then accept it and respect their answer. Maybe they will change their minds.

How do you get big planes in airport tycoon 3?
Build a 2000 meter runway for big planes, and then build at least two terminals. When your airport rating is high enough, go to contracts, and then go to refueling. There you must choose the highest refueling company (2 stars or more). Next go to the catering section in the contracts group and do the same. Now you should have more airline contract offers that have big planes! This video should give a good example: http://www.youtube.com/watch?v=sJDF0loNd74
