Wind flips plane over on runway - not following the rules...


The BBC has a great little clip of a Cessna being blown over on landing at an airport in Colombia.

Watch the clip here : http://news.bbc.co.uk/1/hi/world/7859807.stm:

It's interesting for two reasons:

1) The fact that you hardly ever see 'little' accidents like this filmed - especially in such close-up detail
2) The weather was, apparently a contributing factor, but you have to ask if such a tailwind existed why was the pilot landing on that runway?

Remember the piloting skill more important than all the others? How about how to walk away from your crosswind landings? And the three most dangerous landing mistakes pilots make? All these may have helped the pilot as he attempted the landing.

One person was slightly hurt in the crash.

On the subject of aviation (and that is what this site is about), Virgin Atlantic are in the news again for two reasons. Firstly the have been sent a fabulous complaint letter about the food on their Mumbai-London flight and secondly they have the best commercial on TV at the moment. Enjoy! And see how many subtle jokes and references you can spot.

The Piloting Skill More Important Than All Others

The Piloting Skill More Important Than All Others
By Doug Daniel



This is the one skill that makes the difference between good pilots and so-so pilots. It applies to visual flying and instrument flying, to gliders, land planes and seaplanes, to single engine planes and multi-engine planes, to jets and props. Often referred to as attitude flying, it is really taking charge, deciding what you want to do and doing it.

You must hold the airplane in what ever attitude you choose. For example, the secret to a three-point landing is to put the airplane in a three point landing attitude just above the runway at the right airspeed and hold it in that attitude until it lands. Don't put it in the three-point attitude then let the nose drop. Hold it in the attitude. Be in command.

The secret to successful instrument approaches is to decide what heading, altitude or rate of descent, and airspeed to fly then to take command and fly. Don't chase the needle; don't let the heading wander; and don't drift off altitude; just take charge and fly.

The secret to successful crosswind landings is to align your fuselage parallel to the runway with your rudder pedals, control your airspeed with your elevator controls, and keep your airplane exactly over the center line of the runway with your aileron controls. You cannot do this by letting your nose weave aimlessly, by letting the airplane drift around, or by letting the nose pitch up or down. You must be in command. You must know exactly how you want your airplane oriented in space then you must put it there.

As the airspeed changes and as the wind gusts, your control input must change accordingly. Put that behind you. Don't even think about it. Just think about the airplane's attitude compared with what it should be. When the airplane so much as twitches out of place, put it back where it belongs. You must do whatever it takes to keep the airplane in the attitude you need.

You cannot control an airplane's attitude if you are not continuously aware of its attitude. Sounds straightforward, doesn't it? But this is the reason that some pilots seem to be passengers rather than pilots. They don't yet have that sense of situational awareness that all good pilots possess. How then to have situational awareness?

Think about the airplane's attitude more than any other parameter. When flying visually, spend most of your time mentally out of the airplane. Don't be a casual observer. Don't say, "Oh, the horizon is slowing dropping. Isn't that interesting?" Think of the world as staying still and of the airplane's attitude as changing. As soon as the nose starts up, bring it back down. Certainly you want to tweak the trim so you don't need to concentrate, but put the pitch attitude where is should be. That is your task. Be in charge.

The same advice is valid for instrument flying. You can still be mentally out of the airplane even if there is nothing to see when you look out the window. The attitude indicator and every other flight instrument tell you something about your airplane's attitude.

Whether in the clouds or clear sky, you must maintain a mental picture of your airplane in space.

Know what your airplane's altitude should be; always know what your airplane's altitude is; and make them the same.

Is Flying For Everyone?

By Harry Cameron


As we at the beginning of a new year again a lot of people will want to do their private pilot license. Obviously there are many reasons for wanting to fly varying from achieving a long term goal, a life long dream, the start of a new career or maybe simply to be able to say:"I can fly". Whatever the reasons are I often get asked by a new student "do you think I'll be able to fly".



Maybe firstly we must ask ourselves what does it take from an individual in order to fly an airplane or helicopter for that matter? A certain amount of co-ordination comes to mind. In my opinion most people has what it takes although some has to practice and exercise this particular skill. Discipline I think plays an important roll as flying involves quite a bit of responsibility in some way or the other. My personal favorite is of course a person's attitude. The willingness to study, the way an individual handles criticism and the ability to handle stress but to name a few. These are just some qualities amongst hundreds.



I think every student should and can answer the question: "will I be able to fly?" for themselves. For some it might take longer than the minimum requirement but determination and will pull them through. Many a time students has told me that flying is not for them and I take my hat off to a person that can realize their own lack of ability or whatever reason they base their decision on. Your personal motive for wanting to fly plays a very important roll. So I personally think that it's not a simple black and white answer to be made by an instructor but rather a combined decision.



I think that in the beginning students base their abilities solely on the "stick and throttle" aspects of flying, rightly so because that's all they know but I often tell students that a good stick and throttle pilot is not necessarily the best pilot and that they must consider their other strengths as well when they make a decision whether to continue flying or not. In a lot of cases all it takes is a bit of a mindset change.



I personally think that almost any person can be taught to fly but I think the real question should be whether any person can be a safe pilot not necessarily the world's greatest pilot, and that's maybe where the instructor or flight school for that matter plays a very important role.



If ever you face the decision to quit flying or not maybe think what is your motive for flying, ask yourself whether you enjoy it or not, can you financially afford it to carry on longer if need be, do you need to change your attitude?

Whether the weather be hot. Or whether the weather be not....

As a VFR rated pilot the one thing I am constantly looking to understand and master is the weather. That and the price of oil are the two things that govern the amount of flying I can do in a given period of time (When oil is up aviation gasoline is expensive and I don't fly as much)

So is there a simple way to learn and understand the weather? Yes there is - get a book and learn it. There is no substitute for understanding why weather does what it does and how clouds are formed etc. etc.

In the short term though as a pilot you will want to be able to decrypt a TAF or a METAR.

So let's have a look at these. First things first

A TAF is a weather forecast. It's easy to remember this because it has an 'f' in it like forecast. A METAR is a current state.

TAF's and METAR's are usually written in shorthand with a HUGE number of abbreviations, but they all, generall,y follow a very similar format. Learn the format and you are well on the way to understanding what is what.

Here's a typical METAR: EGLF 031420Z 06004KT CAVOK 02/M05 Q1028

When translated that becomes
:


Conditions at:

EGLF
(FARNBOROUGH, GB) observed 1420 UTC 03 January 2009

Temperature:

2.0°C (36°F)

Dewpoint:

-5.0°C (23°F) [RH = 60%]

Pressure (altimeter):

30.35 inches Hg (1028.0 mb)

Winds:

from the ENE (60 degrees) at 5 MPH (4 knots; 2.1 m/s)

Visibility:

6 or more miles (10+ km)

Ceiling:

ceiling and visibility are OK

Clouds:

unknown


Weather:

no significant weather observed at this time




It's not difficult really.. You start with the location of the METAR (EGLF - Farnbourough) and the date and time (all times are in zulu - UTC or Greenwich Mean Time as it used to be called) 031420Z This is the third of the month at 14:20 zulu.
Following that is the wind information
06004KT (from 060 degress at 04 knots)
Then the cloud conditions:
CAVOK (Ceiling and visibility OK)
Then the temperature:02m05 (2degrees temperature and minus 5 degress dew point)
Finally there is the atmospheric pressure
Q1028 which is 1028 millibars (this is a UK setting in the US this would be something like 29.92inches of mercury)

A TAF is very similar to a Metar except that it identifies a time period for which it is valid and adds information about expected weather conditions:

EGLF 080729Z 0807/0815 25004KT 2000 BR SCT005 BKN035 TEMPO 0807/0811 BKN005 BECMG 0811/0814 6000 NSW



This can be translated as
Forecast for: EGLF (FARNBOROUGH, GB)
Text: EGLF 080729Z 0807/0815 25004KT 2000 BR SCT005 BKN035
Forecast period: 0700 to 1100 UTC 08 January 2009
Forecast type: FROM: standard forecast or significant change
Winds: from the WSW (250 degrees) at 5 MPH (4 knots; 2.1 m/s)
Visibility: 1.24 miles (2.00 km)
Ceiling: 3500 feet AGL
Clouds: scattered clouds at 500 feet AGL
broken clouds at 3500 feet AGL
Weather: BR (mist)
Text: TEMPO 0807/0811 BKN005
Forecast period: 0700 to 1100 UTC 08 January 2009
Forecast type: TEMPORARY: The following changes expected for less than half the time period
Ceiling: 500 feet AGL
Clouds: broken clouds at 500 feet AGL
Weather: no significant weather forecast for this period
Text: BECMG 0811/0814 6000 NSW
Forecast period: 1100 to 1500 UTC 08 January 2009
Forecast type: BECOMING: Conditions expected to become as follows by 1400 UTC 08 January 2009
Winds: from the WSW (250 degrees) at 5 MPH (4 knots; 2.1 m/s)
Visibility: 4 miles (6 km)
Ceiling: 3500 feet AGL
Clouds: scattered clouds at 500 feet AGL
broken clouds at 3500 feet AGL
Weather: NSW (no significant weather)


So basically you can split this into three sections - a 'main' section indicating the general forecast:
EGLF 080729Z 0807/0815 25004KT 2000 BR SCT005 BKN035

A 'temporary section' indicating differences for a subset of the time
TEMPO 0807/0811 BKN005

and an expected transition after that temporary time
BECMG 0811/0814 6000 NSW

Once again we have location (EGLF - Farnbourough) followed by a time of forecast (080729Z - 7.29Zulu on the 8th of the month) with validity time following that (0807/0815 - from 7.00hours until 15:00 hours on the 8th)

After the timings and validity we arrive at the wind information : 25004kt (Wind from the WSW at 4 knots)

Then comes the visibilty information : 2000 (2000 metres = 2 Km)
Then the predominant weather information BR = mist
Then the cloud coverage scattered clouds at 500 feet AGL and broken clouds at 3500 feet AGL

Temporary sections indicate conditions between certain hours in this case 07: 00 and 11:00 on the 08th where the cloud will be broken at 500 feet.

For a complete list of what the different weather abbreviations mean, visit this page. I know it looks like there are a lot to remember, but if you think about it there aren't actually too many. For example if you do most of your flying in the South of England the chances of you having to remember 'VA- Volcanic Ash' and 'PO' for 'Dust/sand whirls - Dust devils' are unlikely. Typically there will be the following

BR - Mist
SH - Showers
SN - Snow
RA - Rain
DZ - Drizzle
HZ - Haze
FZ - Freezing
OVC - Overcast
FG - Fog
GR - hail
PY - Spray

If you live in Southern California, or near Mount St Helens, Washington, there are probably different ones you need to be wtaching out for....
