The region assignment program allows for new controllers to select one of ten global regions around the world, control any airport within that regional boundary at any time, and remain within their area of operation on a more permanent basis. Read more about the change here.

8 New IFATC Trainers

July, 3, 2021 by Kyle Boas

Summer is in full swing here in the northern hemisphere, which means that more people than ever are joining IFATC. In order to accommodate a significant increase in demand for training services, the IFATC Training Team is embarking on the biggest expansion undertaken in its five-year history. After significant deliberation, a total of 8 new trainers are being added, all hailing from diverse backgrounds across the globe. They were chosen for their commitment, dedication, and significant experience helping others in and out of IFATC.

Please join me in welcoming the following people.

Was I denied because I was in a general aviation aircraft?

July, 2, 2021 by Kyle Boas

The controller is responsible for their airspace and they need to be able to accommodate everyone whenever possible.

The reason for denying any aircraft is very situational, it may be difficult to tell why you are denied, so to say you were denied because you are a certain aircraft type is jumping to a conclusion. If you get a “no light aircraft” command sent your way, well then sure. That’s where the education comes in, you have to ask the controller to find out why they sent you a specific instruction. You can on the forum, here is our directory.

It must be specifically reserved for airports that do not accept light aircraft IRL (e.g. EGLL, OMDB, VHHH etc), as 4.2.1 says in the ATC Manual.

My most memorable moments controlling has been fitting in slower performance aircraft in busy airspaces.

We service the pilots they don’t provide a service to us. You just got to work with what you have and fit them in, it’s part of the fun.

Meeting your trainer halfway

June, 30, 2021 by Kyle Boas

Do the leg work on your end by studying the position you will be training for before training, to the best of your ability. The speed at which you advance is based solely off the knowledge you have going in and your ability to implement new things you learn.

Meet the trainer half way and watch the tutorials, ask questions, practice on your own. Review the following:

Be prepared and make the process smooth. It is so refreshing to meet someone who puts in the effort beforehand. Going in halfway isn’t going to get you far.

Staying calm in high pressure situations

June, 29, 2021 by Kyle Boas

This is a great reminder that it’s always in your best interest to stay calm in high pressure situations. Your body’s fight or flight response will attempt to make you shut down and stop communicating.

Both controlling and flying is all about making split second decisions. Being concise and making up your mind quickly will lower your workload, and allow you to evaluate the situation.

VASI versus PAPI lights

June, 28, 2021 by Kyle Boas

Visual Approach Slope Indicator (VASI) is the most common visual glidepath system. VASI consists of lights arranged in bars that are either 2-bar or 3-bar systems. The 2-bar VASI has near and far light bars and the 3-bar VASI has near, middle and far light bars. The principle of VASI is to provide a colour differentiation between red and white to help indicate that you are on the correct glidepath.

Precision Approach Path Indicator (PAPI) system. PAPI uses lights similar to that of the VASI system, except they are installed in a single row, normally on the left side of the runway. PAPI, like VASI, provide only one visual glidepath that is normally set at 3°.

What to do when you’re lost while flying

June, 26, 2021 by Kyle Boas

The age-old problem that always presents itself, from ancient mariners to modern-day aviators, has been finding the way. The world’s too large to be able to know every single bit of it.

How To Have the Best Possible Session at London Heathrow

June, 25, 2021 by Kyle Boas

When IFATC regions were introduced, I knew I had to choose my home region of EU-West. Ever since the 1st of May, I have tried to control EGLL on a regular basis; therefore, during this period of time, I have figured out certain tips and tricks that I will share with you today to make your sessions at EGLL the best they can be.

As we can see in the airport diagram, EGLL has two runways the north runway, 09L/27R and the south runway 09R/27L. Depending on traffic levels, no “light aircraft” and “no pattern work allowed” are recommended in the ATIS. Secondly, per 4.1.4 in the ATC manual, all runways should be used. Therefore, depending on weather conditions, both 09s or 27s should be used for take-off and landing. This will make your life much easier because you can spread traffic across the two runways, which will also provide a much more efficient service to the pilots, both inbound and on the ground.

As there is a north and south runway, traffic can be spread accordingly. Inbound traffic is simple, if the pilot is north of the airport, they should be vectored to the northern runway and any pilot south of the airport should be vectored to the southern runway. If approach or center is active, then you would need to communicate this to them just to make sure you are on the same page. Traffic on the ground works in a similar way. If you can draw a line in your head in the middle of the airport, any traffic above this line should be sent to the northern runway and any traffic below it should be sent to the southern runway. However, if the plane is roughly central then they should be assigned the runway with the least traffic.

Lift produced by an airfoil

June, 24, 2021 by Siddhansh Narang

Lift produced by airfoil varies with angle of attack. Each airfoil has a stall angle or critical angle of attack after which the lift generated decreases.

Every airfoil profile has a unique plot which shows how lift changes with increasing angle of attack. The lift produced by an airfoil is expressed by coefficient of lift or cL. Higher the cL, more will be the lift produced.

Shown in the image is the cL versus alpha (angle of attack) plot of the NACA0012 airfoil (as obtained from AirfoilTools). Here each line is the plot of the airfoil for a different Reynold’s number. As we can see, the cL peaks at an alpha of about 8, and then starts decreasing. Hence we can ascertain that the stall angle of this airfoil is 8 degrees.

MIT’s Xfoil tools says the same thing. After multiple convergence plots for the NACA0012 for alpha varying from 0 – 10, we get the stall angle of 8 degrees, with the maximum cL being 0.84 for a Reynold’s number of 100000.

An interesting fact is that symmetrical airfoils produce zero lift when angle of attack is zero, however asymmetrical airfoils may produce positive or negative lift with zero angle of attack. This is an important factor which is considered while choosing a suitable airfoil for an aircraft.
