There is almost nothing I love more than being inspired by someone, and your mom’s post about your love for swimming pools and measuring their depths, coupled with your interest in airplanes and numbers, well, it got my brain all excited and filled with lots and lots of thoughts.
And all those thoughts started bouncing around my head in this “let me out, let me out” sort of way.
I bet you know that feeling.
It is a happy feeling, isn’t it.
It makes me jump up and down and use all the energy my body has.
Well, guess what I did with all that energy your love of pools and airplane and numbers created…
I got into my airplane and flew way up in the sky, and all the while, as I got higher and higher, I took photographs of pools for you!
It was so much fun!
It made me so happy.
And I sure hope these pictures make you happy too.
But first, before I show you the pool pictures, I want to share with you some important numbers that pilots must know to fly airplanes safely.
I wanted to share these with you because I know you are really smart with numbers.
Every airplane a pilot flies has its own set of numbers. Big airplanes have really big numbers, but because I fly a little airplane, the numbers I learned are much smaller.
This is the airplane I used when I learned to fly…
It is called a Cessna 152. It holds just two people. I flew with a flight instructor until I learned enough to fly by myself. Then one day he said, “Charlotte, you are ready to fly by yourself.” It was challenging and exciting to learn to fly. I am so glad I did!
This is me flying…
And now Tyoma, here are those airplane-related numbers I promised you…
When I am ready to take-off, I line the airplane up at the end of the runway and push the throttle full forward. This makes the airplane start to go as fast as it can. When it reaches 50 knots, I am at rotation speed. That means the airplane is now moving fast enough lots of air is rushing under the wing. That rushing air produces the lift needed to fly. So I pull back on the yoke, the nose goes up, and the airplane leaves the ground.
One day when you are driving with your mom and dad, ask them if you can stick your arm out the car window. You will feel how all that rushing air makes your arm want to go up. That feeling you are getting, that’s lift, and lift is what makes an airplane fly!
Once the airplane lifts off, it begins to climb. As I climb it is very important to maintain a very specific speed. My airplane’s cruise climbing speed is 80 knots.
Then, when I have reached the altitude I want to stay at, there is another speed I use. This is called the cruising speed. My airplane likes this speed. The cruising speed for my airplane is 111 knots.
My airplane can go faster, and sometimes I let it, but there is a speed I must never go faster than because it is not safe. This is called the never exceed speed and that speed for my airplane is 149 knots.
Well, as you know, a law of physics tells us what comes up, most come down, and you guessed it, there are speeds for descending also.
The time when the runway is straight ahead of me and I am just about to land, is called “on final” and that’s when I fly the airplane at 60 knots.
Finally, when the airplane reaches a speed slow enough there is no longer any lift generated under the wing, my airplane will gently touch back down on the runway. This is called the stall speed, and for my airplane this speed is 45 knots. (Notice how this speed is 5 knots slower than rotation speed. Those 5 knots make all the difference in lift and that is why it is so important pilots know the numbers.)
Okay, let’s look at pool pictures now!!!
I put the altitude in the corner of each photo so you will know how high I was when I took each one. All altitudes are MSL (mean sea level).
Oh, I have one more number for you. I used a zoom, 200 mm lens to take these pictures. It sure helped make the pools look so much closer when I was thousands of feet away from them!
Do you think you can figure out how deep these pools are? If anyone can, I know it would be you!
Tyoma, I know I have already told you this, but I really, REALLY had a fun time taking these photos. I think it is SO COOL you like all the things you do. You keep wondering about the world around you and going out to find the answers to your questions.
I think you are awesome! And so is your mom!
Well guess what?
I have stayed up way past my bed time writing this. Yes, even moms like me have bed times! So I better go now.
Have fun and keep learning!
