Most pilots of complex piston singles have had the “GUMP” landing checklist drilled into them by their instructor: “G” – gas selector to fullest tank, “U” – undercarriage down, – “M” – mixture rich (or best power), and “P” – prop full increase. Your plane may or may not have other checklist items to perform, such as cowl flaps closed for example. But execute the GUMP check properly, and things should go relatively well.
But it’s equally important when executing touch and goes to ensure that when one attempts to raise the flaps from approach to take-off configuration, one does not inadvertently raise the landing gear instead.
That’s going to be costly.
