“I learned about Flying from that” – Book Review

"I Learned About Flying From That" book

Book Review:  I Learned About Flying From That, Vol. 3 from the editors of Flying Magazine

I bought I Learned About Flying From That book last summer and really enjoyed reading it so I thought I’d share it.  It is a compilation of stories chronicling near-misses in flying, that were submitted by readers and originally published in the actual “Flying” magazine.  The articles are a series of entertaining stories of pilot’s real experiences of a situations that could have turned out much worse – and many times the outcome could have been much worse – and someone has survived to learn a good lesson from it.  The purpose is to alert other pilots to expect the unexpected and serve as a warning flag when things could potentially go very wrong.

The book is organized in ten different sections, each relaying a series of short stories from that topic. For example: pushing limits, fuel starvation, engine trouble, navigation, good luck, and showing proper respect, to name a few.   It is a very enjoyable read, a book you can go back to again and again to reference information, or just for an interesting read.

I found the articles both entertaining, informative, and educational.  I recommend it, it’s great for pilots and non-pilots, too.

You can purchase the book here.

Your Flight Instructor

Sarah and Me at CYBW

Good flight instructors, bad flight instructors

I really liked watching the show Flying Wild Alaska. It has since been discontinued.  It is a bit overly dramatic but the flying footage they have is fantastic.  The show is about a family who runs an airline a remote region of Alaska.  In the show Ariel Tweto, is featured as she is the only one in the family without a pilot’s license.  One of the last episodes I watched follows her working hard to learn how to fly.  It made me think of how important it is to  have a good flight instructor.

Ariels’ instructor seems to have an unstructured and random approach to instructing and doesn’t appear that he is very patient with her.  It may be portrayed this way through the show on purpose to make it dramatic. But …

In the show, she is portrayed as something being wrong with her because she doesn’t get something right away and has to be reminded on each flight.  On several counts her instructor makes the statement that “if you don’t get it, then you’re out of here.”  Seems harsh.

Learning takes time, a patient instructor is crucial

Learning takes time, and I don’t actually think you’re supposed to “get it” right away.  Learning to be a pilot requires hard work, and above all time, studying, and hours, to properly learn everything to be proficient.  Even the flight training manual, the structured guide used to train pilots in Canada states that earning your license is really just a “license to learn.”  So it is strange when the show portrays shame in learning  by showing instructor roll his eyes and getting upset when she doesn’t do something properly.   It doesn’t portray the learning process accurately.

On what looks like to be one of Ariels initial flights they demonstrate stalls. This seems very early since at that stage she can’t have much of an appreciation why an aircraft stalls or what the aerodynamic properties of the stall are.  The show portrays her as a bad pilot by making it seem like she is inadvertently causing the stall.  It takes awhile for the aircraft to stall, and if she is causing it by accident on her first flight, it’s not her fault, but her instructors, who should see it coming.

Me with my instructor Atanas. He's cool, but sometimes I just want the airplane to myself!

My first big mistake on one of my initial training flights

On my second flight, my instructor Sarah asked me to pull out the throttle as we were practicing descents.  I, still very green, confused, but eager, went for the red knob instead of the black knob – I pulled out the fuel-air mixture knob instead of the throttle, starving the engine of fuel and causing it to die!  Sarah immediately pushed it in and the engine restarted instantly.  I only knew of what happened after she calmly explained to me what I had just done, not losing her patience or getting angry.  She was the instructor and could handle any screw-up that I made.  If she had handled that situation differently, I would have been upset, and nervous on subsequent flights.   I probably wouldn’t be excited about my next flight.

I am really lucky to have had two really great instructors since I’ve started my license. I did most of my training with Sarah but she is only teaching intermittently now, so I do most of my training with Atanas. I have a lot in common with both of them and enjoy spending time with them, in the airplane but also socially, on the ground. It makes such a big difference to have a good instructor who encourages you to do your best.

A good instructor will make you feel great every time you fly, even if it wasn’t the world’s greatest flight. It’s learning, and you should try hard every time you go and feel good about your efforts. Not every flight is going to be fantastic but on every flight you will learn something.  Having that positive encouragement is what makes the difficult process of learning to fly easier to bear.

Yay for flight instructors!

Slow Flight – more detail on slow flight techniques

I talked with my instructor last night and he brought up a few very good points about slow flight.

In my post about slow flight in the Cessna 172 I wrote that there are five signs that we can identify we are in slow flight;

  1. Stall horn cutting in and out
  2. low airspeed
  3. high nose attitude
  4. high power settings
  5. sloppy aileron control

But we can extend these concepts to some of the other flight surfaces.  What happens to the rudder and elevator? We know that because of a nose high attitude we are pushing the boundary layer of laminar and turbulent airflow further up the wings – hence the wings receive less smooth, laminar airflow and are subject to buffeting from the turbulent air.  This renders the ailerons sluggish and slow.

But how does this effect the tail of the aircraft?

Torque and Asymmetric Thrust

Recall that because of torque the aircraft wants to spin counterclockwise. This is because the propeller spins clockwise (when we are in the cockpit) and the airplane is a gyroscope – this tendency is explained by Newton’s third law.  Most aircraft are designed in a way to anticipate this, so in level flight, for example, many are designed to give more lift to the wing that is being forced downward. Torque means that the plane has a left turning tendency because more force is applied to left wing than the other. But this is only for level flight. When the aircraft is out of level flight, such as a take-off attitude or nose high attitude that we experience in slow flight, the aircraft will want to turn to the left. Hence, this is another effect on controls of slow flight.

Asymmetric thrust also means that the descending blade has a greater angle of attack than the ascending blade.  This gives more lift to the right side of the propeller (as seen from the pilots perspective) and a yaw to the left.  This happens during high power settings and in high angles of attack – just like in slow flight.  In level flight, both propeller blades meet the relative airflow equally (again, the thrust issue is anticipated in the design of the propeller) and they produce equal thrust, and no left yaw.

In addition, we also talked about why we need to learn slow flight. We are not actually in slow flight on approach and takeoff, but we are very close. We do not want to be in slow flight during these maneuvers, and want to be able to recognize when we are in too close. The airplane is no fun in slow flight – the ailerons are sluggish, the nose is high so our visibility is restricted, the engine is at high power settings and very loud. So the whole point of learning about slow flight is to avoid it.  It is not a comfortable flying experience.  Yesterday I learned how to do a slow flight with almost full power settings and full flaps. It was awkward flying it in this configuration.

So, another way we know we are in slow flight is due to (6) left yaw tendencies requiring use of right rudder to correct. This will be the sixth way we can identify we are in slow flight.

Lesson Log

My coveted flight log

Today I read an interesting story on the Flying Magazine website about keeping a journal of “flying lessons” throughout your flying career. They suggest that it is useful to write down the things you’ve learned from every flight.  For the article, click here.

I’ve kept a log book like this since I’ve started flight training. I can’t express how useful it has been. From my first flight where I clung to the control column with an iron fist, being too scared to even look outside, to doing my first takeoff, my first radio calls, my first stalls, to gaining more aptitude, losing my fear, and being able to confidently fly on my own and take photos at the same time – it’s all there in chronological order.  It’s fun looking back at some of my old entries and seeing how far I’ve come.  There are also useful bits of information that I always refer back to. I mark important sections such as when I learned specialty takeoffs and landings – soft field and short field – and other exercises like slow flight, stalls, and circuits, for the first time.  I also highlighted the point when I switched airports and instructors.

I highly recommend a book like this during flight training. What’s more, is this type of tool can be useful throughout your flying career, since a pilot is always learning. A quote I really like is one I’ve read in a book about flying – where a student pilot asks his instructor how long it takes to learn how to fly and he responds “I don’t know, I’ve never finished.” A good motto to take along? I’m not an experienced pilot, but I know enough to know that with flying, you never stop learning.

The Soft Field Procedure

Before I learned precautionary and forced approaches, I learned about soft field landings.  Here my account of the experience, and why soft fields are important and should be practiced regularly.

When will we use a soft field landing?

If we are planning to land on an unprepared surface. We also need to know the technique if we need to make a precautionary or forced landing, and have to put our airplane down in a field.

Like the short field procedure, the soft field is a lot of fun.  It is used when taking off and/or landing on an unprepared surface. The can be a grass strip or turf runway, or a completely unprepared runway.  One of the main goals is to protect your propeller and engine in the sequence. This means we try to keep it from being struck by flying debris and damaged, and to keep dirt and debris from being sucked into the engine.   It also is to keep the nose gear from diving into a hole – since it is an unprepared surface there may be lots of surface irregularities.  A small dip and we could wheelbarrow the plane.  We keep the nose high throughout the procedure as long as we can.

It starts during the taxi

Can I land my airplane in that field?
Can I land my airplane in that field, and what is the technique?

In fact, when we taxi on the unprepared runway we keep our control column full aft.  So when we pull up to line up on our runway we are pulling back as far as we can on the control column.  When we add power, we push forward slightly on the column until the airplane is ready to fly.  We rotate at about 46 knots with 10 degrees of flap in the 172 N model.

We fly in ground effect until we have built up enough airspeed to climb.  This is about 60 knots, so when we reach 60 knots, we pull up and climb out.  At 200′ AGL we announce that we have “two positive rates”

(1) altimeter increasing (showing a gain in altitude), and

2) vertical speed indicator increasing, and we retract the flaps and climb out normally at 70 knots.

Hold off on the landing

The airplanes POH will show us what speed to approach for our soft field landing.  In the 172, we use 61 knots.  The idea on the flare is try to hold off landing even longer than usual to keep the airplane nose high.  So after we flare and we feel the first “sink”, we add a bit of power, around 100 RPM or so and try to keep the airplane from touching down. We do so until we have run out of altitude, and the airplane will touch down very softly.  We keep the nose high to protect the propeller and keep from nose gear from running into rough terrain.

Soft field touch and go’s are probably the most fun of all – we do not push the nose down, and take off right away in a nose high attitude.  That means we stay off the nose wheel and just do a “wheelie” down the runway, and take off! In my solo I managed to make this happen a few times.

The Forced Approach and Landing

So now that we know about the precautionary procedure, what happens if we have NO engine power?

We plan a forced landing! The image above shows an actual forced landing of a Boeing 737 jet. TACA Airlines Flight 110 lost power in both engines and successfully glided and landed on an unprepared, makeshift field (image courtesy of airliners.net).

Is planning a forced landing possible?

For those who believe that a successful forced landing is difficult or impossible to achieve, Transport Canada’s “Flight Training Manual” (FTM) reminds us that for glider pilots every landing must be a successful forced landing. Hence, it is not only possible that it can be done, it can be done well.

Yesterday I went through the basics again with my instructor.  Each instructor has a different way of teaching, so the method will vary slightly for everyone.  The basics are more or less the same.

Famous Forced Landing: The ditching of US Airways Flight 1549 into the Hudson River. Image Source: wikipedia.org

The most successful recent emergency forced landing was US Airways flight 1549: a ditching in the Hudson River. After multiple bird strikes into the engines caused dual engine flameout,  the gliding Airbus A320, which didn’t have enough altitude to return to the airport, was successfully ditched in the Hudson River. Like all pilots, trained in forced approaches, he captain used the same line of thinking that we are taught when learning how to execute a forced approach and landing.

We are flying along – and – we’ve lost engine power! What is the first thing we do? We fly the plane.

(1) Best Glide Speed

We have to establish our aircraft in “best glide speed.”  For the Cessna 172, this is 65 knots. The best glide speed provides the maximum “lift to drag” ratio and allows the airplane to glide as as long as possible.

(2) Best Field

Now we have to look outside and quickly locate the best field where we will put our aircraft.  We locate this field, and turn towards it.  Look for indicators of wind direction on the ground, and make your best efforts to land into the wind. If in doubt of wind direction, simply plan to land in the same direction that you took off from the airport.

Make sure to do a good check of the suitability of the area for landing. This means: check for civilization, obstacles, wind, field length, and landing surface – abbreviated the COWLS check.

(3) Fault

Now that we have our field chosen and have established our glide, we have some time to do some quick engine checks to try to determine the cause of engine failure. Often, with carburetor equipped aircraft such as the Cessna 172 the engine can die due to carb icing.  Or if we descend from a higher altitude and we fail to richen the mixture. These quit simple steps will attempt to reestablish engine power and will not cause us to loose too much time and altitude.

Fuel Selector Valve: Both

Mixture: Full Rich

Carb Heat: On

Ignition: Both

If it doesn’t start, we simply shutdown the engine using the same steps as above:

Fuel Selector Valve: Off

Mixture: Idle cut off

Carb Heat: Off

Ignition: Off.

The above three steps should take us about 500′ of elevation loss to do. Since this is a simulation … we do an engine warm up by adding 200 or so RPM.

(4) Mayday Call

Before we get too low we make the Mayday call. We say “Mayday” three times and our aircraft identifier three times (just like in the case of a precautionary landing).  Broadcast your location, your intentions of where you plan to put the aircraft, the nature of your emergency, and the number of people aboard.

(5) Passenger Brief

Let your passengers know: to put their seat back, stay clear of flight controls, put away all sharp objects, and so on.  You can let them know where the ELT and fire extinguisher are.  Also, it is important to ask them to unlatch the door prior to touchdown.

If this landing is on an unprepared surface, your landing will be a soft field landing.

Make sure to assess how the prevailing winds will affect your approach and landing. What are the upper winds doing?  Also state that you intend to touch down on the first third of the field.  For the Cessna 172, we touch down slightly tail low and turn off the electrical as instructed in the POH.

Successful Forced landings

Another example of a very successful forced approach is in the case of Taca Airlines Flight 110 on May 24, 1988. After flying through severe thunderstorms, the jet lost both engines that the pilots were not able to restart.  In the perfect moment the captain found a grass field and pointed the giant gliding 737 towards it. He was able to land successfully with no loss of life and minimal aircraft damage. In fact, Boeing engineers were able to do the necessary repair work on the spot and the aircraft was flown from the very spot where it was landed! Watch the video of the incident below.
