Avoiding Prop Strikes

avoiding prop strikes and you'll want to avoid these for starters they're expensive and require a full engine teardown and often an engine overhaul propeller tips approach the speed of sound and the centrifugal forces or centripetal acceleration amount to 10 to 20 tons per blade that coming in contact with anything will hurt especially if it's you so always treat the propeller as if the magnetos are hot depending on the aircraft you fly and your prop's length your ground clearance can vary dramatically so be vigilant for dips and debris on taxi takeoff and landing pilots flying aircraft with especially low clearance like a mooney have to be extra vigilant on taxi and on landing have to be careful not to release too much back pressure too quickly if you keep your nose wheel from banging into the ground in front of you or your tail wheel from bouncing around behind you you'll be doing yourself your propeller your engine and your firewall a favor landings are when pilots get into trouble the most let's learn from some of their mistakes in this air safety institute classic takeoffs and landings the ups and downs of the ga pilot [Music] now i want to show you some examples of landings our cameras captured at a recent fly-in the conditions that day required normal piloting technique but some of the landings you'll see are anything but normal no one can accuse this pilot of being too hot on final oh boom okay he's gonna try it again there's that better the first landing would have been great on an aircraft carrier but here on land i've got to give that a 3.9 this 182 appears set up nicely but wait the pilot lets the nose drop ouch we hope he didn't do that on porpoise but he's sure giving his oleo strat a workout and the local a p might get some work out of this too can you say potential prop strike that's a 2.0 arrival in my book here it is from the reverse angle look how nicely the plane's set up and how quickly it all goes south that's what happens when you don't maintain the proper landing attitude bouncy landings are often the result of trying to touch down with too much speed porpoising can begin after a bounce where the pilot who expected to touch down and stay down now finds themselves back in the air and with the nose high the natural inclination is to push the nose down but if you push the nose down too much it can lead to the nose wheel hitting the runway before the main gear and starting the bounce and attempted recovery process again at this point the pilot can get even further behind the corrections and the oscillations can continue until the prop hits first before the nose wheel and it doesn't take much for a nose low attitude to result in a prop strike sometimes just a few bounces will do it if you find yourself in the beginning of a forfeit best choice is to smoothly adjust your angle attack while adding power go around and try again this go around will feel different than the go-arounds we typically practice probably be very close to the ground the stall horn might be going off might have a higher than normal angle attack and a much lower air speed than you normally begin to go around with remember the benefits of ground effect as you transition back to the runway into the air to help stabilize your go around while you're in the pattern determine why the porpoise began were you too high above the runway or too fast correct for it on your next attempt if you do have a prop strike do not attempt to go around cut the power and stay on the ground when you're ready to shut down conduct a p-lead check get on your checklist and get to the habit of doing it at the end of every flight if you don't know how check your manufacturer's recommend when exiting the aircraft perhaps to refuel or talk to somebody make sure the keys are out and on the dash in plain view for everyone's awareness and that's what this comes down to awareness be aware of your surroundings be on guard during ground operations land on speed and don't accept a sloppy touchdown [Music] you
