6 NAVIG. EXAM. PREP.

260 After establishing contact with Athina Radar for MATZ penetration and receiving Radar Advisory Service, the controller asks you to turn onto a compass heading of 045 to avoid fast moving fighter jet traffic. Assuming deviation is 6o W, what is the heading? (T)

261 The surface wind for take off is given as 245/17 knots. The maximum demonstrated crosswind for the aircraft is 12 knots. Which of the following runways are within the limitations of the aircraft? (Fig.13)

262 VOR reception may be affected by i. night effect ii. atmospheric static iii. terrain surrounding the station iv. aircraft altitute v. the height of the VOR station The correct combination is

263 An aircraft is flying from Lamia to Ioannina (90 NM) away, with a required track of 304°(T). The initial heading is 314(M). Var 2°E. the expected drift is:

264 Operational Navigational Charts (ONC) and Tactical Pilotage Charts (TPC) as those cover the Hellenic area, are

265 In the ideal chart should: i. Not exist orthomorphic depiction ii. Scale be constant and true iii Exist orthomorphic and isochoron depiction iv. Angles be measured and depicted precisely v. Great Circle or Rhumb lines be depicted with straight lines vi. The Latitudes and meridians are cut with 90 degrees angle. vii. Not exist orthomorhic and isochoron depiction viii. Great Circles and Rhomb lines depicted as curved lines

266 Isogonal is ………(i)…………and agonic line is………(ii)……………

267 Conformal (orthomorphic) chart in aviation means:

268 What distance on the Earth represents 5.2 inches on the chart of Cyprus (1/250.000)

269 9'' on the chart of Greece scale of 1/500.000 equal 62 NM. How many kilometers represent 9 inches on the chart of Cyprus, scale of 1/250.000

270 Navigational Chart of scale 1/250.000 as those depict the U. Kingdom or Cyprus area are based on:

271 ''A line on the chart in a particular position will have the same direction as exactly corresponding line on the earth at the same position.'' This ιs called":

272 Flying at FL 125, the reception range of VHF airborne communication transceivers with a sea level situated ground station, is approximately:

273 The earth's shape is best described as:

274 (i) Meridians are rhumb lines, (ii) Parallels are rhumb lines

275 Only one GC can be drawn between two points on the earth's surface. This is:

276 A nautical mile is:

277 The radius of the earth in NM is approximately:

278 A kilometre is:

279 Automatic computing equipment in an aircraft that accurately measures the groundspeed in terms of standard nautical miles (FMS or GPS…..) and then uses this to calculate geographical co-ordinates using 1 nm = 1852 m, will be least accurate when flying:

280 The length of a nautical mile:

281 A rhumb line is best defined as:

282 A parallel of latitude is a:

283 At 10:00 UTC the a/c from it's position at 3000 ft (OAT +10?C), pulls up and climbs en-route with constant IAS 180 kts, on track 090? and with climb rate of 1000 FPM, up to FL250(OAT -30?C). The estimated wind for the entire climb is 040?/30kts. What time is estimated to be established at FL250 and what should be it's position according to Dead Reckoning calculation?

284 An a/c departs from Florina aerodrome and flies to destination (Alexandroupolis LGAL) at FL200 (OAT -24?C). It is supposed to be established over its destination airport at 2000 ft (OAT +12?C). The desired track is 090?(T) with IAS 200kts. The estimated wind in the mid altitude of descent is 320?/40. The descent rate is 900FPM. How long does it take to start descent and what should be it's position by Dead Reckoning calculation before descent begins?
