The discussion of "GUMPS" in the complex thread got me thinking about this again. What memory devices do y'all use in the air? Here are my favorites: GUMPS (of course): Gas (tank/pump) Undercarriage (down or welded) Mixture (rich) Prop (full forward as appropriate) Switches (landing light, etc.) and Seat Belts For a go-around or missed approach: Climb it, (Full power, carb heat off, pitch up) Clean it, (Flaps, gear, flaps, flaps) Cool it, and (Cowl flaps open) Call it. ("Podunk Traffic, N12345 going around" or "Muni Tower, N12345 missed") Preparing for an approach: PAIN CALL Position (Where am I? What am I doing next?) ATIS (or AWOS, etc... Get the weather) Instruments (Set DG and Altimeter) Nav radios (TITS sub-checklist) - Tune - Identify (switch Nav# on audio panel, verify correct Morse ID) - Twist (OBS to proper course) - Set Markers (for ILS) Com radios (Center/Approach on #1, Tower on standby or Tower/CTAF on #2) Approach briefing Landing checklist (GUMPS) Listen (for approach clearance) Callouts for the approach: Localizer alive, Glideslope alive, 500, 200, and 100 feet for each descent, and DH/MAP. And, of course, the 5 T's. Turn, Time, Twist, Throttle, Talk. My cruise checklist isn't so much a memory device as an "I already have it memorized anyway" type of thing. Trim, Time, Lights, Pump, Power, Mixture, Compass, Cowl flaps. I recite this when I'm done actually doing it to make sure I didn't miss anything. I memorized it because if I pull out a checklist at that point, I seem to always drift high. I also do a GUMPS, 5T's, and "Lights, Camera, Action" for takeoff after briefing the takeoff. ("Camera" being the transponder.) On the roll, it's "airspeed alive" and "engine gauges in the green" callouts. So, what others do you use? Any callouts?
