He~

He might be too enthusiastic, he might be weak, and he might be overactive. But he's trying to be part of this world of flying. He never die out his passion. Learnt himself that he's going for his dream, and Flying is every pilot's soul. He wants to be a pilot no matter what, because he likes to fly. Outgoing as well to meet all friends throughout the whole world. And that he is me :)

Straight And Level, Sounds easy but Hard Reality

Straight and Level, in a flight simulator game, it sounds easy as you engage autopilot. But in reality is different. It requires your great and accuracy judgement from your brain and how well you judge a straight and level flight. The term straight and level means the aircraft is not going up, not going down, not going right and not going left. How well you judge a straight and level flight depends on individuals.

Recently, I found out myself that flight simulator is not that realistic as every instrument and the engine parameters are too ideal in terms of instrument not lagging and engine parameters whereby it gives 100% Load and high speed flying. For eg. 100% Load on your throttle whereby Airspeed will go for 100-120 knots on climbing, however in reality to achieve a 80kts climbing on 100% Load would be quite hard and it's simply magnificent and hard to remember all the procedures and checklist just for takeoff and climbing. But well, my instructor,Captain Yiap does not want ask to learn everything at that instant.

Let's talk about straight and Level. Imagine we look the aircraft from the side view.
To talk straight, from this angle, it means we don't let aircraft go up and down, which means gain or lose height.
To talk about Level, from this angle, it means we don't let aircraft go left and right.

To combine both of them, straight and level means the aircraft doesn't gain any height or lose any height, as well not going left nor going right. It sounds easy, but light aircraft like our aircraft, Diamond DA-40, is very fragile in terms of their control, but it's very stable. This require your ability to trim and judge correctly about your datum altitude. Everyone has their different way of judging on position of datum altitude. To get this datum altitude, measure 3 fingers below from the earth horizon to your aircraft dashboard. But I would like to mention again about measurement of 3 fingers, whereby individuals have different measurement. But 3 finger measurement is the basic one. For mines, I had 2.75 of fingers measurement, but you ask me how I was managed measure it with decimal points, it's simply unexplainable. My partner, Desmond had 3.02 measurement, which is even hilarious.

Flying Straight and Level to me was quite hard actually, especially you have to find the datum altitude. In this straight and level exercise, you need to know how to maintain straight and level by scanning the required instruments, which is Vertical Speed Indicator (VSI), Directional Indicator (DI), and Turn & Slip Indicator (TSI). These three instruments must maintain their original position though. It's very important to learn this straight and level, whereby your future career needs this straight and level scan in future to maintain smoothness and unnecessary movement for passenger flight.
It takes times to learn how to scan. Instruments will be covered, which don't allow you to look for so long but to scan them. VFR flights are meant for visual flights. It's like your driving, you can't keep looking into your instrument for your speed. You have to look outside to check for any traffic, any terrain and the road or path you are going. It's very important that you don't stare to the instruments.

So, as cadets, you might be scolded by your instructors. They will shout at you, asking what you need to know, and scold you on flight. But be alert that they are experienced. They want you to know what you need to study and to know. It's depend on yourself that you know how to judge correctly and learn properly. Preparing yourself as I had mentioned in my last few blogs will improve your learning.

See ya guys~
