What you say is true IF there are no instruments on board, but I saw at least TWO instruments in front of you which tells you if you are turning. ONE is the TURN AND BANK indicator; the other is the COMPASS. We VFR (Visual Flight Rules) pilots are taught how to use these instruments to maintain level flight if we should inadvertently get into IFR (Instrument Flight Rules) conditions.,(reply>), We only realy have an compas and try to use an compass when youre upside down it joust doesent work
