Cessna 152 Aerobatics

2012-02-14T07:48:00.000Z

This is the most amazing Cessna 152 Aerobatics video I have found on YouTube. Wish our Cessna at the school could pull off such moves.

WARNING: Before you try such manoeuvre, make sure you have (A) the proper aircraft (acrobatic), (B) proper training and (C) balls to do so!

Google Docs in Bangla (WTF)

2012-02-12T15:31:00.000Z

We are trying to get started with a new website to be launched next year (2013). I was setting up different accounts before they get taken away from us by someone who'd use those for 1 week and then leave it for good. When I went to Google Docs to save some of my important documents I was in a shock! The whole thing was in Bangla. Bangla, being my mother tongue, is like a piece of cake to me. However, I could not read or understand anything that was written on it.

GOOGLE, if you really want to translate some other languages, you better get some good translators.

I loved these Breakfast tunes so much that I had to mash these up to make one longer version. Here's it with some beautiful time lapse videos.

How you should advertise your plane

2012-02-01T11:00:00.000Z

Air New Zealand and Biman Bangladesh Airlines (I highly doubt that by the time you click Biman's link it'll still be working! In that case, just Google 'Biman') recently got the deliveries of their newly purchased Boeing 777-300ER aircraft. While Biman advertised vaguely (by which I mean it hasn't actually done anything yet) about it's new aircraft; Air New Zealand on the other hand had gone making some Full HD videos and joined them together and put the finished product on Youtube. Have a look!

Calculating Density Altitude with a Pencil

2012-01-29T10:17:00.000Z

We all know that as density altitude increases, there is a corresponding decrease in the power delivered by our airplane’s engine and the effectiveness of our propeller. For a typical non-turbocharged light single-engine airplane, this can result in a takeoff roll that’s 25 percent longer for every 1,000 feet of elevation above sea level. The most dangerous combination of conditions are a heavy load, unfavorable wind, high temperature, high airport elevation and high humidity.

With so many variables to consider, how are we supposed to know when our density altitude is too great for the conditions? The answer is, we need to calculate our density altitude, which we can then compare against the performance information in our aircraft manual.

We could use an E6B computer or an iPad app to calculate density altitude, but what if we accidentally left the flight computer and iPad at home? Is there an easy way to calculate approximate density altitude without the aid of these gadgets?

There sure is, and it’s a formula we as pilots should probably commit to memory.

First off, what is density altitude? From our private pilot exam prep, we know it is “pressure altitude corrected for non-standard temperature.” That’s just a fancy way of saying it’s where the airplane “feels” like it is. For example, if the density altitude is 5,000 feet at sea level, your airplane is going to take off as though it’s already flying at 5,000 feet.

How do we calculate density altitude? There are just two pieces of information you’ll need for a rough approximation: pressure altitude and temperature. Where do you find this information? Easy: for temperature, you look at the thermometer in your airplane. For pressure altitude, set the window in your altimeter to 29.92. Whatever value it reads is pressure altitude.

Finding pressure altitude when you're not sitting in the airplane is a bit more complicated, but here’s a nifty formula:

pressure altitude = (standard pressure - your current pressure setting) x 1,000 + field elevation

That’s a pretty simple formula since two of the variables will always be the same and the other two are easy enough to find. Let’s say our current altimeter setting is 29.45 and the field elevation is 5,000 feet. That means (29.92 - 29.45) x 1,000 + 5,000 = 5,470 feet.

Easy! Now let’s move on to step two, finding density altitude. Here’s the formula:

density altitude = pressure altitude + [120 x (OAT - ISA Temp)]

Now, before your eyes glaze over, here’s how simple this formula is: We already have the value for pressure altitude from our last calculation; OAT is degrees Celsius read off our thermometer (let’s say it’s a balmy 35 °C today) and ISA Temp is always 15 °C at sea level. To find ISA standard temperature for a given altitude, here’s a rule of thumb: double the altitude, subtract 15 and place a - sign in front of it. (For example, to find ISA Temp at 10,000 feet, we multiply the altitude by 2 to get 20; we then subtract 15 to get 5; finally, we add a - sign to get -5.)

So, in the example above:

density altitude = 5,470 + [120 x (35 - 5)]

Working out the math, our density altitude is 9,070 feet.

This is a rough estimate, but it will be pretty close to the actual value. Try this formula the next few times you go flying (or, just for fun, run some scenarios using Microsoft Flight Simulator) and before you know it you’ll be able find your ballpark density altitude without digging in your flight bag for that E6B. (END)

However, if you are interested to learn how to calculate density altitude with the E6B, have a look at the following picture that I've scanned from Jepp PPM

See the difference? How many buildings, you reckon, have been built in these 10 years? In 2001, the building that I live in didn't even exist. I wonder how Dhanmondi would look like 10 years down the line.

Cessna 152 Cockpit

2012-01-06T06:41:00.000Z

It's the best cockpit ever.

I'm going to miss it heaps. My new plane has all the latest avionics and systems. However, I will always maintain that the Cessna 152 cockpit, all the black and white dials, and the feel of flying it is mind boggling.

These fishes were huge!

You might be thinking seeing the photo that they don't really look big at all. But trust me on this; they are pretty big. I love this culture of sending decorated fishes representing the bride and groom to the bride's home in the morning of the first event of the wedding ceremony.

They look awesome.

Winter drying

2012-01-02T19:21:00.000Z

It caught my eyes from a distant.

The shirt originally looked pale-blue. Someone obviously thought that having it hanged outside in the winter morning drizzle would be a very good idea to have it dried!

My favourite car of the moment. < Ferrari 458 Italia >

2011-12-09T16:03:00.001Z

This car is giving me insomnia.

When it was first launched a couple of years back, I pretended not liking it over the Enzo Ferrari (Ferrari F60). However, secretly, at the back of my mind I had a thing for this incredible car. I had to admit all these years that it has been the prettiest Ferrari I have ever seen.

Wish I could have a go in it!

Boeing 787 Dreamliner showers future dreams at VGHS (Dhaka International Airport)

Youngone Flight Department | Arirang Aviation Ltd.

2011-12-04T03:19:00.000Z

Youngone Corporation established its corporate flight division in 1999 to meet its own corporate need. Initially, the company started its flight operations with a Cessna Grand Caravan aircraft to operate in domestic and regional routes. Such corporate flights facilitated diversified activities of the company with greater degree of flexibility.

With the increasing demand and necessity vis-à-vis safe operation by the grand Caravan, encouraged the company to induct a brand new Pilatus PC-12 aircraft in 2004. The PC-12 aircraft offered more comfort, less time and increased range to cover long-distant flights. Subsequently, Youngone purchased 2 brand new multi-engine Piaggio P-180 Avanti II aircrafts for covering even more long- distant destinations in less and less time. Today, Youngone has a fleet of five aircraft which are capable of meeting multifarious mission tasks. Having such versatile fleet in its inventory, Youngone planned to launch commercial flight operations by establishing Arirang Aviation Limited.

Cirrus SR 20 | My First Flight

2011-10-28T16:38:00.000+01:00

It's really hard to explain how good it felt. I got a bit carried away. It's properly brilliant. Apart from the manual rudder trim which can paralyze your leg. I am sure there is no such light aircraft in Bangladesh, which makes me one of the luckiest to be in it and fly it for a while.

God, I love the Cirrus.

I made this video on our journey en-route from Dhaka (VGHS) to Chittagong (VGEG).

A dead landing strip

2011-10-16T12:43:00.031+01:00

It felt eerie the whole time i was circling around it.

This morning I was getting prepared for one of my most important flights. If I can be honest, it was going to a be an important flight for my school as well. It is because in this flight I'd, with my instructor, set way points for myself and the rest of us for smooth operations in future. You could call it a Test Flight (sort of)!

The weather looked alright from the ground. When we were holding short of taxiway 'A'; we received an unusual request from the CTG (VGEG) tower. As we were flying west, the controller requested us, kindly, if we could take some aerial photos of a dead-disused landing stripe from the WWII era. This meant we'd have to deviate from our original flight plan, fly overhead the landing strip, circle, and take some photos. Sounded nice(ish!)

The landing strip was pretty hard to locate. To verify we went as low as 300ft.

FYI the landing stripe is located in a place called Shudharam, which is somewhere near Noakhali.
