Me­te­o­ro­log­i­cally speak­ing, what is the ‘ceil­ing’ at an aero­drome? a height of the base of low­est cloud of any de­scrip­tion that is within 10nm of the air­field b height of the base of the low­est vis­i­ble layer

of cloud that cov­ers eight ok­tas c height of the base of the low­est layer of cloud which cov­ers more than half the sky (four ok­tas) and which is lower than 6,000 me­tres (20,000ft) d height of the base of the low­est layer of cloud which cov­ers more than six ok­tas and which is lower than 6,000ft. 4

You are climb­ing at full power, head­ing in an east­erly di­rec­tion and see that the mag­netic com­pass is read­ing ex­actly 100°. Which of these could be your ac­tual mag­netic course? a 093° b 105° c 112° d 118° 5

In the ICAO Stan­dard At­mos­phere freez­ing level is 7,500 feet. The ac­tual freez­ing level, of course, is usu­ally dif­fer­ent from that fig­ure. In which of these months does the ac­tual freez­ing level in the skies over Europe most fre­quently ex­ceed 7,500 feet? a April b June c Au­gust d Oc­to­ber 6

If a 30 to 40-yearold pi­lot is of av­er­age build and rea­son­ably fit, at what g-force will the phe­nom­e­non of ‘blackingou­t’ first be­come per­cep­ti­ble to him or her? a 2g b 3g c 4g d 5g e 6g
