1285 An a/c departs from Kerkyra (LGKR) at 12:00 UTC to fly to Paros (LGPA) which is 290 NM away, with TAS 150kts. Desired track is 118(°T) and initial heading is 110(°T). At 12:20 UTC the a/c's position is fixed 10NM left of track over Arta which is 55NM away from departure. W/V and immediate alteration at 12:00 to destination is requested.

- AO All of them are true.
- BO An error code for military use is being randomly transmitted.
- CO An electric power supply failure can occur at any time.
- DO We must not rely only on high-end technologies, but mainly on human instinct.
3287 Rhumb line is defined………………?
- AO as the line on the earth cutting all meridians at the same angle
- BO as the line on the earth cutting all parallels of latitudes at the same angle

- DO as the line connecting small circles on the earth's surface
4288 Variation (var), is……..?
- AO the angular difference between true and magnetic bearings in any place and defines as EAST and WEST

- DO for the depiction of local areas around the equator
6290 The disadvantages of Mercatorial Projection are…………..

- AO False
- BO True
9293 Why is it necessary to know the altitude of the Tropopause?
- AO all of them are correct
- BO because great changes of wind and temperature may exist
- CO because high winds (known as Jet Streams) may be encountered
- DO because due to temperature and wind change, clear air turbulence may be encountered
