Top 5 Private Pilot Stumper Questions FAA Checkride

hey guys what is up john and steph here from fly8 mike alpha.com today coming to you for private pilot stumbler questions some questions that might stump you on your prior pilot check right they'd probably stump me if i was going for my check right today but luckily we're watching this video so you're not going to be stumped exactly and luckily the pro pile check ride is well behind both stephanie and i so but for you it might be upcoming and this is all just a small part of what is online at flightmikegolf.com in both the private pilot written prep boot camp as well as the private pilot check ride crash course so aptly named uh check out that course the link is in the description below if you want to see more videos like this to prepare you for your prior pal checkered we guarantee you'll pass your checkered when you take that course everyone passes their check right when they take that course great course all right guys let's jump into the first question okay what rpm level would make you a board a takeoff due to not producing enough power so i'm like going down the runway and what rpm would you be seeing that would make you think oh this isn't really producing enough power i should abort this takeoff well if the europeans too low i wouldn't go what would be too low how do you know it's too low she's so tough isn't she man well you're going to have to refer to the type certificate data sheet the tcds to find the specific minimum static rpm as well as maximum static rpm specified for your airplane unlikely that you're going to find it in the poh so on the type certificate data sheet on the fa website if you just type in say cessna 172 tcds and then find the exact model of your cessna 172 and verify that is the correct engine in there so we'll have some engine models make sure that if it was built with 150 horsepower that's what's on the type certificate data sheet that's what's still in the airplane so you know you're getting good data and then verify that you have the right propeller on there it'll have some propeller model numbers that are associated with that engine and it'll say for that engine and propeller combination you should get between say 23.50 and 2400 rpm static so if it was below that minimum number then i would abort the takeoff okay sounds good to me yeah all right well then i have a question for you my question is when we look at this airport here it says right on the sectional chart here how long the runway is it has that number there so is that how long the runway is is that how much room you have available for landing well in some instances that is the amount of room that you have but in other instances there is a displaced threshold which means that you have slightly less room to land and you can use that threshold to take off but not to land so for example the sarasota airport says 95 there does that mean there's 9500 feet available for landing not necessarily and you would have to look at your chart supplement to know exactly how much room there is to land in each runway because that number only pertains to the longest runway of that airport you might have multiple runways that are not all that length yeah so in this case we can see sarasota here the pavement itself is 9500 feet long there's 9500 feet of asphalt there but whether you land north or south or one four or three two you're not going to be landing at the beginning of the runway both have displaced thresholds neither landing direction has a full 9 500 feet available for landing is actually a lot less than that so checking that chart supplement very good idea there okay well i guess it's your turn now to answer a question sure and my question is what is hydroplaning and how do you prevent that from happening or how do you stop that from happening all right so hydroplaning is when we're touching down on say a paved runway and we have a lot of rain a lot of standing water perhaps it's still raining so there's a film of water between our tires and the runway we touch down and our tires actually don't pierce through that water same way those cool guys on youtube do it water skiing down a river or lake or something spraying water everywhere they're actually not in danger of diving down into the water unless they get slow enough at high speeds water acts like concrete and we actually can't pierce through the water with our tires so although it's a not recommended and kind of a terrible idea to do that as a private pilot what they're doing on youtube for us as private pilots it's concerning to us because if we land on a very wet runway our tires may not actually contact the pavement we might be water skiing across that runway just you know maybe a half inch above or a quarter inch above the actual tarmac surface and we won't have any braking authority so what would we do in that case well we have to use the only breaking authority we have available in which case would be aerodynamic breaking authority so raise that nose leave the flaps where they are try to cause as much drag on the airplane as possible the only way you're going to get those tires to pierce through that water and contact the pavement is to get the airplane slower once you are hydroplaning you can hydroplane at a much lower speed even so perhaps the minimum hydroplaning speed for that tire entire pressure is maybe 40 miles per hour to start hydroplaning so you land at 50 you're hydroplaning but you could hydroplane even below that number since it's already begun so once you do finally pierce through that water you want to use light breaking once there's contact between your tire and the pavement so that you're not skidding or potentially hydroplaning all over again aerodynamic braking is the only thing we have available to us to actually get the airplane slowed enough to then eventually start using brakes so in the event we have a wet runway or it's raining or anything like that i would always choose a longer runway than needed to land at i would never be landing at say a two thousand foot or three thousand foot long runway i might consider landing at a four or five thousand foot long runways on personal minimum just because in my 172 if i was to hydroplane i could burn up a lot of distance very quickly and certainly managing my approach speed and energy not touching down too fast not coming in with too much speed will help that okay that sounds really good awesome so question for you then this examiner you don't get to ask the examiner any questions on the day your check right so this is kind of fun let's say we're flying along we've got this awesome radio stack here we've got all these fancy cool buttons and we dial up the tower we're coming in to land oh i don't know maybe at the punta gorda tower in florida and we're 10 miles out and we dial them up and we give them our whole spiel puna gordon tower cessna one two three four five ten miles north landing with juliet and the tower comes back and says aircraft calling punta gorda tower that was carrier only what in the world do they mean by that are you gonna go land on an aircraft carrier not really um have you ever heard sometimes when you're flying around there's just sounds coming into your headset and it sounds like somebody's king the mic but nobody's talking what do you mean like when a private pilot or when a student pilot keys the mic makes the transmission then forgets to let go of the mic for another five or six seconds and you just kind of hear breath on the frequency or just that kind of somewhat static noise or that electronic noise right but no one's talking so in this case you wouldn't even hear breath because something is wrong your your voice is not coming through but you're keying the mic and so they're picking up that somebody's king the mic and trying to talk but no sound is coming through so the radio carrier the transmitting carrier is being transmitted but not your voice yeah so why would that occur well there's a number of different issues the most common one is if your mic jack is not plugged in all the way so that would be the first thing to check and then either way could it be that you were just flying along singing out loud kind of like you sing in the shower and you actually have the microphone tilted up to the side and so you made a radio call but the microphone was so far away nobody heard it and they just heard the carrier i usually have the microphone out of the way so i can eat snacks oh yeah or maybe you're eating snacks maybe i like to kind of sing when i'm flying but something like that that could certainly cause it so yeah make sure the microphone's actually in front of your face make sure the mic jack's actually plugged in carrier only means that yes the transmit button is working you're transmitting but you're not actually transmitting any voice across the frequency now is it your turn to ask me a question i think so my question is regarding elt batteries okay and my question is somewhere in this book i know the answer is in here when are you supposed to replace an elt battery you're supposed to replace an elt battery if more than 50 percent of the battery's used for life has been used up or the calendar wise and then uh if it's been in operation for more than one cumulative hour okay very good well how do you know that it's been in operation more than an hour i'm just gonna go ahead and tap myself out of this one that's a pretty tricky question how would i know if the elt battery has been used for more than one cumulative hour since it was installed in the elt and in that aircraft there's not a clock on them there's not a counter on it of any sort all right guys that is five private pilot summer
