Seeing a sunset or sunrise from the cockpit is a view you’ll never forget. Here’s why they’re so stunning and full of color.

First, A Quick Review Of Sunlight

Sunlight, or visible light, can be thought of as a wave and a part of the electromagnetic spectrum. When the spectrum is split up, you see all the colors as a rainbow.

Each visible color has a different wavelength along the spectrum. Blue light has the shortest wavelength at 300 nanometers. Red light has the longest at 700 nanometers. As visible light passes through the Earth’s atmosphere, small particles in the air can scatter shorter wavelengths more efficiently, like what you see on the left side of the diagram below.

During the day, blue light is the primary wavelength that’s scattered in the atmosphere, and only a portion of the blue light is scattered. But when the sun is low in the sky during sunrise or sunset, all of that changes.

“Scattering” Causes Colorful Sunsets

According to Steve Ackerman, a Meteorologist at the University of Wisconsin, Madison, “because the sun is low on the horizon, sunlight passes through more air at sunset and sunrise than during the day, when the sun is higher in the sky. More atmosphere means more molecules to scatter the violet and blue light away from your eyes. If the path is long enough, all of the blue and violet light scatters out of your line of sight. The other colors continue on their way to your eyes. This is why sunsets are often yellow, orange, and red.”

Red has the longest wavelength of any visible light, which is why the sun may appear red when setting directly on the horizon. The light has passed through the most atmosphere possible before reaching your eyes.

Why Are Some Sunsets More Colorful Than Others?

According to National Geographic, you may see more vibrant sunsets based on the seasons. In the east, fall and winter create incredible sunsets because the air tends to be dryer and cleaner for the path of sunlight.

Pollution tends to mute and muddy the colors of sunsets because large particles in the lower atmosphere tend to have that effect. And in general, places with a lot of haze have less dramatic sunsets.

Why Sunsets Look So Great From The Air

When you’re flying through layers during climb or descent, you’ll find the best sunsets where the sun is clearly visible between multiple layers of clouds.

When sunlight is sandwiched between cloud layers, it bounces off the clouds, further intensifying the sunset. That’s why sunsets often times seem more spectacular from the air.

On top of that, cloud layers can create dramatic shadows on the ground, or on other cloud layers.

Where Is Your Highest Risk Point For Stall-Spin Accidents

Where Is Your Highest Risk Point For Stall-Spin Accidents? By Colin Cutler

PrimaryBoldmethod

Nobody thinks it will happen to them. But before you know it, there you are. Low, slow, and approaching a stall.And how well you react in those few seconds makes all the difference in the world. Often times, it’s the difference between a safe recovery and a fatal crash.

Where Do Stall-Spin Accidents Happen The Most?

The Air Safety Foundation conducted a study of 450 stall-spin accidents from 1993 to 2001 to see where they happened, and how they compared to other types of accidents. And to keep the focus on GA, they only looked at accidents where aircraft weighed less than 12,500 pounds.So where did the accidents happen? At least 80% of them started from an altitude of less than 1000′ AGL.What’s the significance of 1000′ AGL? It’s the traffic pattern altitude at most airports.

spin-height

That brings up the major problem with stall-spin accidents down low. The altitude loss in a stall recovery for most GA aircraft is estimated to be 100-350 feet. Which, in many cases, gives you enough room to recover from a stall in the pattern.But spins are a whole different animal. In the 1970s, NASA studied altitude loss in spins of several aircraft, one of which was the Piper Arrow.What they found was eye-opening. The Arrow had an average loss of 1,160′ in spin entry through recovery. And, keep in mind, that’s in an aircraft flown by a test pilot.

arrow-spin-recovery

It doesn’t take a math genius to figure out the problem here. If you’re flying a 1,000′ AGL traffic pattern and you get yourself into a spin, you’re not going to have enough altitude to recover, no matter how quick your reaction, or your recovery technique

Staying Alert, Especially Down Low

This, like most things in aviation, always comes back to the basics.There’s no substitute for flight proficiency. And when things start to fall apart in the pattern, going around and giving yourself another chance is almost always the best option.So the next time you’re flying, climb up to altitude and practice some stalls and slow flight. And if it’s been a long time since you’ve done either, grab an instructor so they can give you feedback on how you did.A little practice and proficiency can go a long way. And it can keep you reading about accident studies like this, instead of becoming one of the NTSB’s statistics.

Four Tips for Late-Summer Flying

Leave a comment

Source: 4 Rules-Of-Thumb For Late-Summer Flying | Boldmethod

Rules-Of-Thumb For Late-Summer Flying; by Colin Cutter – 
Thanks to Boldmethod for sharing…
1) Calculating Civil Twilight
Summer days are getting shorter, but there’s still a lot of daylight left.
A good rule-of-thumb for calculating civil twilight is that it usually ends between 20-35 minutes after sunset. Tonight in Boulder, CO, sunset is at 8:05 PM, and civil twilight ends at 8:34 PM. That’s a difference of 29 minutes. Once twilight ends, you can start logging night flight time. But remember, you need to wait an hour after sunset to log night landings.

2) Takeoff roll increases about 10% for every additional 1,000 feet of density altitude
There’s no sign of the weather cooling down yet. And on hot days, you get high density altitude. For most normally-aspirated GA airplanes, you’ll add about 10% of takeoff roll for every 1,000′ of DA. For example, if your airport’s density altitude on a hot day is 3,200′ over field elevation, you’ll increase your takeoff roll by about 32% over an ISA day. So if you have a 1,500′ takeoff roll on an ISA day, you’ll increase that roll to almost 2,000′.

3) Stay a minimum of 5 miles from storms, and up to 20 miles if you can.
Flying closer than 5 miles from visible overhanging areas in storm clouds puts you at risk of flying through hail and severe turbulence. That’s not good for your plane, or your passengers. In some cases, aircraft have encountered hail, severe windshear, and severe turbulence up to 20 miles from storms. When in doubt, keep your distance.

4) Add Half The Gust Factor On Windy Day Landings.
As we approach the end of summer, windy days increase across the US, because the jet stream starts moving south. When you’re dealing with a gusty day, the FAA recommends that you add half the gust factor to your final approach speed to give yourself safe padding from a stall. For example, if the winds are reported at 18 knots, gusting to 30 knots, it means you have a gust factor of 12 knots (30-18 = 12). So if you take half the gust factor, you get 6 knots (12/2 = 6).

Boldmethod

To apply that in an SR-22T, Cirrus recommends that you fly final at 80 knots. So on a day with a 12 knot gust factor, you’d add 6 knots to the published 80 knots, for a final approach speed of 86 knots. The same math works for any GA airplane’s final approach speed. Just add half the gust factor to your final approach speed.

A Beginners Guide to Aviation Photography

Thanks to “An Adventure in Awesome” for sharing.  Knowledge without application is meaningless –Thomas Edison

Part one: Some thoughts on Aviation Photography

Troll disclaimer. This is not the only way to photography aircraft and aviation events. This is information that I have learned and what works well for me. My tips and tricks may not work well for you. My goal is to share what I have learned with others. Knowledge without application is meaningless. –Thomas Edison

This is the start of series that would help someone start to shoot aircraft and aviation events more successful. This has been a project I have had in minds for years now. When I first had the idea, I wanted to do it as one lengthy article but never manage to find time to complete it. Now here, it will make a great series, giving me time to figure out topics, how to say as well as find images to support the post.

Before we go any further, there are two things I want to address. First, make sure you RTFM that came with your gear! And for those of you who are unwilling to read, you’re in luck. There is a wonderful website called YouTube where you can search the make and model of your gear and watch a video on how to use it. Before you start shooting anything with your gear, you should have a basic understanding of how to use it. I can’t stress enough how important it is to know how to use your camera and gear properly. Here’s the thing, I’m going to be using some basic terminology of photography like ISO, Shutter/Aperture Priority, F-stops to name a few and I’m not going to define or explain them. These are a few things you should know what they are as well as how to access them on your gear. Just because you own a camera, does not make you a photographer! And second, what gear you should have to shoot aviation events with. For most of us, this is a hobby and we do something else for a living. I know I do not have $10 to $15,000 to drop on gear and tell anyone who want to start shooting aircraft is unrealistic. That is why knowing how to use your gear properly is so important. Yes, having great gear helps but it is absolute useless unless you know how to use it properly. Like anything you buy, you get what you pay for. A $4600 camera body does far more than a $700 one. Buy the best that you can afford, learn to use it properly, find and work around its limits then grow into better gear.

Let me share with you my feelings about Aviation photography and want to get you to start thinking about how you feel about it. When I think about Aviation photography, I don’t think about all the airshows and aviation events I want to attend however I do think about a list of aircraft set in great lighting conditions where I can create unique images. For me, it is a passion. (going to have a future post on Passion and what it means to me) It’s something that if I was told that I could never shoot aircraft and any type of aviation event ever again, I would fight for my life to keep shooting what I love. It is something that I’m never going to stop trying to master. I love being behind my camera making new images as well as being around aircraft of any sort. Warbirds to modern fighters, from helicopters beating the air into submission to spotting airlines at the local airport. If it flies, I want to try a make a great image of it. I also feel that like any other art form, it should be creative and not just documenting aircraft and aviation events. Using elements of design to create visual interest, adjusting my camera setting to get a sense of motions along with telling a story.

This leads me into my first question for you, “What makes a great image?” I feel it comes down to three things, light, subject and the story behind the image. How well did you capture the light along with what does the image say? I’m no professional but I do know a great image when I see one. And in those images, the photographer mastered the exposure, composition and the image speaks to the viewers. You should not have to explain what the viewer is looking at. Great photos just don’t happen, Photographers work hard to make them. You’re going to have to work hard too. Here’s a helpful tip, collect images from photographer that you like and study they’re work. Collect them from Flicrkr, Instagram, 500pix even from their personal website. Books and magazines are also a great source to find image that you like. Ask yourself how did he or she shoot it? If you have a EXIF viewer and the data was not striped from the image, you can as least know what setting were used. What you will not learn is how they saw the image before they shot it. Your “eye” or creative vision is something that you and you alone must develop and nurture. Looking at photos from other photographers can help train your eye to start to see thing differently. It’s not going to happen overnight and you can read every book on photography about to how do so but it’s not going to matter until you try to put what you read into practice.

Every time I’m out shooting, I see other photographers and I ask myself “What’s going to make my images stand out from theirs?” This is the second question I want you to think about. For me, it forces me to get out of my comfort zone and do something different. Can I shoot from a higher location? How’s the light now V’s later? Go portrait or landscape? Always pushing myself and constantly nurturing my skills. Over the years of shooting, failing and learning, I’ve manage to build a collection of images I can call my own. A set of images that are well exposure, creativity composed and unique to me. Every show and event I go to, I try to add new images to my collection but it does not always happen. This is my approach to Aviation photography, to build over the long haul a set of images unique to me from my mind’s eye and from skills that I learned.

On to the last question I would like you to think about is, “What type of Aviation events are you interested in photographing?” There are many to choose from. Airshows, fly-ins, base visits and exercises, museum visits and finally, spotting. All of them offers different perspectives and opportunities to photographing aircraft as well as they have their own unique challenges. I enjoy warbirds and I attend airshows, fly-ins that are mainly cater warbirds as well as visit the museums where they are based. The internet is the best place to find out what is happening and when. Google is your smart friend, used and learn! I will talk more about each type of events in a future post in this series.

The reason why I started with these third questions and not jumping into what’s the appropriate settings and how to pick a show/event is that I wanted to get those deep and untapped juices flowing about how you’re going to approach aviation photography before you start shooting. Along with to get you to start thinking about what is it you’re shooting. Like any other art form, it is a learning process and it going to take time. You’re going screw up shots, use the wrong shutter speed, forget to switch back to your previous settings and totally forget with the sneak pass is coming! There will be plenty missed opportunities to come. It’s just another chance to get it right.

I’m going to cover in future post of this series is the different types of aviation event and what to look for while choosing an event, setting to get results, element of design, panning and spray & pray, chimping and why it helps, getting out of your comfort zone and I will retouch on sorting images.

Avoiding Spatial Disorientation On Your Next Instrument Flight | Boldmethod

1 Comment

Flying through the clouds on an IFR flight can be one of the most exhilarating things you can do. There’s nothing quite like busting in and out of ‘the soup’. Even better, there’s no feeling quite like seeing the runway appear at the end of an instrument approach. But flying through the clouds is not without risk: between 5-10% of all general aviation accidents result from spatial disorientation, and of those accidents, 90% of them are fatal.

Why Disorientation Happens In The Clouds?
Your eyes are your primary sensory input when you’re flying. You look outside, you see which way the sky is pointing, and you adjust your airplane. But all of that falls apart when you’re in the clouds…

How To Not Go Off The End Of The Runway, In 5 Easy Steps | Boldmethod

Leave a comment

If you’re like us, you’re not too interested in going off the end of the runway. Here are 5 simple steps to understand density altitude, and to make sure you have plenty of runway for your next takeoff.

1) What the heck is density altitude?

Density altitude is a measure of how ‘thick’ the air is, and it’s based on a few factors: atmospheric pressure, temperature, and humidity.

The technical definition of density altitude is “pressure altitude, adjusted for non-standard temperature.” What that really means is on hot days, the air is much ‘thinner’, or less dense, than it is on cold days.

Why does that matter? It’s a big factor in your airplane’s performance, because when the air surrounding your plane is less dense, it means your wings, propeller, and engine will have a lot less performance, and it will take you more time to get airborne during takeoff.
