I wouldn't go side-slipping with full flap unless you want a nasty surprise <img border="0" title="" alt="[Big Grin]" src="biggrin.gif" /> . .If your Aztec door opens in flight - don't waste time and energy - just land when reasonably convenient and close it - EGSS once let me land, turn off runway, close door, call ready for departure - and off we went again! Tremendous co-operation! Some Heavies even gave way to let us do it - thanks folks! Only time it has ever opened in flight, I hasten to add. .On the C152, I only ever use the doors for roll/yaw - sometimes use control column in winter - it gets cold. By the way, I also fly all high wing aircraft on rudder, trim and power anyway - plus, of course, doors if I can't get what I need from the rudder - my Garmin sat-nav jobbie is so big, I can't use the control wheel in left/right roll mode - it also spills my tea - attached to centre of yoke <img border="0" title="" alt="[Razz]" src="tongue.gif" />
