![]() We use Vx to provide more margin for error in some takeoffs, but if a Vx climb is required for a safe take off, you probably shouldn’t be taking off. There are some portions of a Vx take-off from which a power failure at Vx will result in a damaged airplane at minimum, in quite a few airplanes. Get an instructor and try doing some engine failure scenarios at Vx. So the 1.404 number matches up better with a Vy climb. So the idea is if you are maintaining altitude you can bank up to 60 degrees (in the video he said 30 deg, but I believe the math is actually 60 degrees) without getting into an accelerated stall using the 1.404 number. I can think of a few times I heard “Too slow, how about we just go back out and start this over?” We all talk about hearing old instructor’s voices in our heads saving our bacon later down the road. And it’s a big hint your head isn’t in the game. Why are we pushing on into an approach or maneuver that’s already hit a major airspeed error? It’s only going to get worse unless you get aggressive about fixing it, right now. how about we execute an immediate go around and go back out and set this all up again, and do it right this time?”ĭan setting it as a must act trigger that’s marked on the ASI is more formal than that, but the concept is similar. It was more of a “If you just got THAT slow, something is totally screwed up with this pattern/approach/whatever. The idea that there should be monitored speeds upon which one will not go below isn’t truly new, and I remember older instructors essentially teaching the same thing long ago without marking it. I think we had a thread already too but maybe not. Vbg on in straight flight.if a turn is needed in the glide, increase speed to 70Īnyway, just thought it was worth discussion. Vx only in straight flight.initial climbout without turns The part I'm trying to wrap my head around handling is the best glide and climb.ħ0.2Kt is of course higher than Cessna's book best glide speed which is 65Kt, and is a good bit higher than the 59 Kt Vx It works for my normal landing/pattern speeds.70 no flaps. ![]() Taken from the narrative under the flightchops vid.from Dan, in part "Vs1 x 1.404 becomes a)best glide b) safe climb speed) c) safe DMMS in the pattern." ![]() So using the multiplier they presented (1.404 VS1) for the cessna 172N I'm currently renting for my rusty clean up/BFR I get Starts about 9:40 into the video,but I appreciated the whole thing and think it's worth watching all the way through for sure. ![]() I was watching the Flight Chops recent video on AQP AFR, which pointed back to a vid of his I remembered watching a few months back with Dan Gryder that in part covered DMMS ![]()
