Peterwarnedmetoignoremostofthenoisefromthe engineandproceededtohandswing.Therewasan unbelievableclatteringfromupfrontandthebig, coarse-pitchpropellerthrashedaroundslowly,soI couldamostcounttheturns.Reductiongearssound, frankly...different.

(ChiefFlyingInstructor,BrightonFlyingGroup)

Withnearlyeverythingbeingreferredtobyinitials thesedays,andaviationiscertainlynoexception,it occurredtousthatthenewcomertoflyingmightlind alittleguidanceuseful,andtheobjectofthesenotes istoprovidethatguidance.

Undoubtedly,thetwogroupsofinitialsinmostuse todayareQFEandQNH.Thelettersthemselveshave nodirectrelationshiptotheinformationtheyconvey. Perhapsweshouldgobacktotheolddaysbeforethe warwhenmostradiocommunicationwasbyMorse Code.Anincomingaircraftwouldcalltheairport 'RequestQFE'inMorse,meaning'Whatisthepresent AtmosphericPressureatofficialaerodromeelevation?'

Backwouldcometheanswer,againinMorse:'QFE xxx'meaningthepresentAtmosphericPressureat officialaerodromeelevationisxxxmillibars'.This informationisvitallyimportanttothepilotasitwill ensurethathisAltimetertellshimhowhighheisabove theaerodromeandanyhillsorobstaclesinthe immediatevicinityoftheaerodrome.Onadescent throughcloudhewillreadfromhischarthisOCL,or 'ObstacleClearanceLimit',thisisthelowestaltitude towhichhecandescendwithoutbeingindangerof hittingthegroundorcollidingwithanobstruction.If hecannotseethegroundwhenhereachestheOCL thenhemustclimbupagainandeithertryagainor diverttoanotheraerodrome.

Thereare,however,twoQNHvalues,the'Aerodrome QNH'andthe'RegionalQNH'.Theformerischiefly usedtochecktheaccuracyofthealtimeterintheaircraft,whilstthelatterisvitallyimportanttothepilot duringhisflight.TheRegionalQNHisthelowest forecastpressureforaparticularregioncoveringa twohourperiod,andisusedbythepilottoensurethat hedoesnotcollidewithanymountainsorother obstructionsonhisroute.Wedonotintendtoallow ourselvestobedivertedintoexplainingtoyouabout AltimeterSettingRegions.YourInstructorwilldoit veryefficiently.Wewillemphasisehoweverthatitis verydangeroustogetthetwomixedup!

OppositetheFlightOfficedooratShorehamwe haveanInformationBoardwhichshouldbeclosely studiedbyeverypilotbeforetake-off.Onitwewill findsomeveryusefulinformationsuchastherunway inuse,theQAN—'directionandstrengthofthe surfacewind,'andperhaps'QNT'25-30knots.This meansthatthesurfacewindisexpectedtogust25-30 knots.Whenusingtheradiopilotsdonot,asarule, usethesetwoextractsfromtheQCode,preferringto speakeverydaylanguage.UseoftheVHFradiois sometimesreferredtoastheR/T(RadioTelephony).
