Kirk 66 Kirk, Did you read: http://www.newyorker.com/reporting/2...a_fact_gawande Here is a quote- "Line infections are so common that they are considered a routine complication. I.C.U.s put five million lines into patients each year, and national statistics show that, after ten days, four per cent of those lines become infected. Line infections occur in eighty thousand people a year in the United States, and are fatal between five and twenty-eight per cent of the time, depending on how sick one is at the start." OK, now here are the steps- (1) wash hands with soap, (2) clean the patient’s skin with chlorhexidine antiseptic, (3) put sterile drapes over the entire patient, (4) wear a sterile mask, hat, gown, and gloves, and (5) put a sterile dressing over the catheter site once the line is in. Clearly these are simple, easy to remember things that don't need a checklist. But they started using a checklist anyway- "the ten-day line-infection rate went from eleven per cent to zero. So they followed patients for fifteen more months. Only two line infections occurred during the entire period. They calculated that, in this one hospital, the checklist had prevented forty-three infections and eight deaths, and saved two million dollars in costs." Agree with most of your comments, BTW, but checklists are sometimes useful for even the simple things. Brian |

And reading some of the "checklists" I see on RAS, they are also more "procedures" instead of checklists. WUFSTALL is getting awfully close to a procedure for me. Kirk 66 |

It's a simple glider, not an airliner. If you can't tell that you have a load of water on board, maybe you shouldn't be flying with water (or at all!). The control feel is entirely different. Same for flaps. Test the spoilers? Why? You'll know as soon as you try to open them and can alter your pattern then. If that's too complex, maybe you shouldn't be flying. Check the wind? You mean that you aren't constantly aware of the wind direction and speed? Drift, crab? Should you really be up there alone? Check trim? Have you been holding constant pressure on the stick? Can't you land with trim locked at either extreme? Should you be flying? I could go on and on, but to what end? When I flew at Bond Springs, NT, Australia, their before takeoff checklist mnemonic was: CHAOTIC. What the heck did that mean? I couldn't remember during the time I was flying there, much less now! In my AF days before takeoff we said: "All shiny switches - Outboard" and before landing it was: "Muff 91, gear check, full stop." I haven't damaged an aircraft in 38 years of flying. I know, some day... (Flame suit on) |

I tend to agree with the idea that checklist should be short and apply
to only critical or commonly forgotten items. When you add too many item and it becomes a procedure then you are likely to miss or skip critical items on the list. Or it becomes so long that you eventally just don't do it at all. W ater U ndercarriage F laps S peed T rim A irbrakes R adio Intentions E nter Pattern could easily be shorted to WU, Water because it can be easy to forget and Undercarriage because it is critical and easy to forget. My Take off critical check list is: Canopy closed (Critical) Controls Checked (Critical) Flight Recorder on (easily forgotton) It is just a sticker on instrument panel. My assembly critical assembly check list is a sticker on the access cover. I don't install the access cover until the check list complete. Brian |

I suppose some have attempted takeoff with the canopy open but Darwin is lurking just around the corner and a checklist won't protect you from him... |

OK, hotshots,
Go read Kern's Airmanship Redefined. We aren't all up here because we have testosterone poisoning. Whether it is a checklist or a procedure, these are good devices for students, low-time pilots, and us old guys who need check lists to help us keep flying. Medical advice for older guys (from MD glider pilots) is to fly more often and use checklists. We aren't all flying international contests and it isn't the Indy 500.

Maybe you need to meet some real glider pilots; you know, the kind that have made mistakes. There are a lot of us - not hard to find! Oh, good grief! It's a simple glider, not an airliner. If you can't tell that you have a load of water on board, maybe you shouldn't be flying with water (or at all!). The control feel is entirely different. Yikes! After flying a ballasted glider for 4 or 5 hours, it _feels_ normal (at least for the four gliders I've owned that used water), and if I'm concentrating on a low save or other intense things, I can forget it. After the first time, I added it to my checklist (meaning - started using one); so far, no repeat incidents. Same for flaps. Read the above, starting with the Yikes!, but thinking flaps instead of ballast. I didn't think it was possible to forget setting the flaps, but it was and still is. Test the spoilers? Why? You'll know as soon as you try to open them and can alter your pattern then. If that's too complex, maybe you shouldn't be flying. If you try them early in the pattern, that can be the test. If you sometimes wait until you are on final, that might be too late to deal with the the problem. I've only had one spoiler incident - frozen closed - but I've read of others having problems, including stuck open and only one deploying. The other reason is to activate the gear warning, in case you forgot that. I've been saved from a gear up landing at least three times by a spoiler activated gear warning, and I'd rather have the warning early in the pattern instead of on final. Check the wind? You mean that you aren't constantly aware of the wind direction and speed? Drift, crab? Should you really be up there alone? I've never had these on my checklist, but I have learned to check the wind several times during a pattern, after being fooled a couple times. Check trim? Have you been holding constant pressure on the stick? Can't you land with trim locked at either extreme? Should you be flying? I don't have this one on my checklist, but I'd say the danger is relaxing and letting the airspeed decrease/increase unintentionally, most likely while you are distracted by other aircraft in the pattern, the radio, people wandering around near the runway, etc. I could go on and on, but to what end? (snip) I haven't damaged an aircraft in 38 years of flying. I know, some day... OK, you don't need a checklist, but I think I see why you can't imagine that some of us find them helpful: you don't make mistakes and you don't get distracted. I make mistakes and I do get distracted. In 36 years of glider flying, I've managed to avoid big mistakes so a dinged wing tip on a landing light is the extent of my damage. It's taken plenty of care, some checklists, revision of procedures, study, and some luck to do it. -- Eric Greenwell - Washington State, USA (change ".netto" to ".us" to email me) |

Opinions are like rear ends. Everyone has one. Check lists are good ideas, they should highlight the critical events like locking the canopy and putting down the landing gear. I heard a story of a glider pilot who landed gear up on the runway with a student pilot in back of him. He couldn't make it off the runway and the student with limited skill and experience dinged his wing. Perhaps a checklist on the panel with "put the gear down," would have saved some repairs.
Just my opinion Walt |
