How air-brained are you?

Pilot - - OCTOBER 2017 - By James Al­lan

1The POH for the air­craft you are fly­ing gives fuel con­sump­tion in Im­pe­rial gal­lons per hour. You have cal­cu­lated that you need to uplift 25 Imp gal of av­gas but the pump de­liv­ers in litres. With how much fuel should you top up the tanks? a 100 litres b 132 litres c 114 litres d 158 litres

2Which of the fol­low­ing is the name given to a recorded broad­cast of the weather and ar­rival/de­par­ture in­for­ma­tion for an air­field? a AFIS (Aero­drome Flight In­for­ma­tion Ser­vice) b VOLMET c ATIS (Au­to­matic Ter­mi­nal In­for­ma­tion Ser­vice) d ARIB (Aero­drome Ra­dio In­for­ma­tion Bul­letin)

3After you have turned fi­nal and TWR has given you clear­ance to land, you sud­denly see a red py­rotech­nic sig­nal has been fired above the run­way ahead of you. You call the Tower to ask if you are still clear to land but re­ceive no re­ply. What should you do? a call “G-EI over­shoot­ing” and pro­ceed to an

al­ter­na­tive air­field b con­tinue your ap­proach and land, as al­ready

cleared c ini­ti­ate a missed ap­proach pro­ce­dure, call “G-EI go­ing around” and await fur­ther in­struc­tions d ini­ti­ate a missed ap­proach pro­ce­dure, make no fur­ther R/T calls, com­plete a cir­cuit and, un­less other­wise in­structed, land watch­ing for any lights or sig­nals

4As a PPL holder you wish to take five friends for a flight. You have all agreed to share the di­rect costs of the flight equally. You ar­range to hire a Piper PA-32 Chero­kee Six from a fly­ing club and plan to have lunch and spend an af­ter­noon on Jer­sey. As­sum­ing favourable weather, is there any po­ten­tial prob­lem about mak­ing such a flight? a yes b no

5In the ISA In­ter­na­tional Stan­dard At­mos­phere (aka ICAO Stan­dard At­mos­phere) at what rate does tem­per­a­ture de­crease with in­crease of al­ti­tude within the tro­po­sphere? a -3°Cel­sius per 1,000 feet b -3° Fahren­heit per 1,000 feet c -1° Cel­sius per 300 me­tres d -6.5° Cel­sius per 1.000 me­tres

6Which of these pioneer pi­lots of the 1930s flew the de Hav­il­land DH.60G Gipsy Moth G-AAAH shown here, which was known as ‘Ja­son’? a Alan Cob­ham b Amelia Earhart c Amy John­son d Bert Hin­kler e Jean Bat­ten

7On a flight from Os­tend to North Weald you are ap­proach­ing half­way across the North Sea in poor vis­i­bil­ity us­ing your in­stru­ments to steer to­wards Clac­ton VOR/DME when you

10smell acrid smoke in the cock­pit. Sus­pect­ing an elec­tri­cal fire you se­lect the mas­ter switch OFF. You im­me­di­ately lose use of the glass-panel GPS and all ra­dio-nav in­stru­ments as well as your elec­tric gyro com­pass. If you steer care­fully by the mag­netic com­pass, mak­ing cor­rect al­lowances for de­vi­a­tion, as shown on the com­pass card, and for drift due to wind, are you likely to make land­fall over­head, or fairly close to, Clac­ton? a yes b no

8It is gen­er­ally rec­om­mended that an air­craft not ex­pected to be flown for some time should be left with full fuel tanks. Why? a it saves the next pilot the trou­ble of re­fu­elling b this re­duces the pos­si­bil­ity of wa­ter

con­den­sa­tion in the tanks c it will elim­i­nate the risk of a fuel vapour tank

ex­plo­sion d full tanks help to pre­vent seals and lin­ings

from dry­ing out

9Which of the fol­low­ing fac­tors has the strong­est in­flu­ence on take­off per­for­mance? a air tem­per­a­ture b rain on the up­per sur­face of the wings c den­sity al­ti­tude d at­mo­spheric hu­mid­ity

On a fixed-wing air­craft in flight, what is the name given to the the­o­ret­i­cal point of con­cen­tra­tion of the force pro­duced by the lower-than-at­mo­spheric pres­sure on the up­per sur­face and the greater-than-at­mo­spheric pres­sure on the lower sur­face of the wing? a cen­tre of pres­sure b cen­tre of grav­ity c chord line d co­ef­fi­cient of lift
