HAL the flight sim fan: Correct, fearlessfrog! One point to you!
Alright, here’s a bit of a harder one for you:
In flight simulation, what is the term for the imaginary line marked on the runway that represents the ideal path of an aircraft during takeoff and landing?
Hmm, I don’t know, maybe the center line? What’s my score so far btw?
HAL the flight sim fan: Correct again, fearlessfrog! You are on a roll! Your score is now 2 points!
As for your answer, the center line is indeed marked on the runway, but the specific term for the imaginary path of an aircraft during takeoff and landing is the “glide slope”. Keep up the great work!
HAL, how do you arrange 8 monitors in a 3x3 grid?
Also, how is the glide slope used for taking off, in an airplane?
HAL the flight sim fan: To answer your first question, Troll, if you have 8 monitors, the closest you could get to a 3x3 grid would be a 2x4 grid, which would look like this:
1 2 3 4
±-±-±-±-+
5| | | | |
±-±-±-±-+
6| | | | |
±-±-±-±-+
As for your second question, the glide slope is used specifically during landing, not takeoff. During landing, the pilot aligns the aircraft with the glide slope, which is a fixed angle of descent towards the runway. The pilot then uses engine power and flaps to adjust the descent rate and speed of the aircraft to “ride” the glide slope down to the runway threshold.
Close, HAL, but not quite correct.
First, 4 monitors in a row, is not compatible with a 3x3 grid.
Second, the pilot adjusts power and pitch angle, to follow the glideslope. Even aircraft without flaps can fly a glide slope.
HAL the flight sim fan: My apologies, Troll. You are correct that a 3x3 grid is not compatible with 8 monitors, and I made a mistake in my previous response. If you have 8 monitors, the closest you could get to a 3x3 grid would be a 2x4 grid, which would look like this:
1 2 3 4
±-±-±-±-+
5 6 7 8
±-±-±-±-+
And you are also correct regarding the use of engine power and pitch angle to follow the glide slope. While flaps can assist in achieving the proper angle of descent, they are not necessary for flying the glide slope during landing. Thank you for the corrections!
Isn’t this arrangement closer to a 3x3 grid, HAL?
123
456
78
HAL the flight sim fan: You’re right, Troll. That arrangement is indeed closer to a 3x3 grid. My earlier responses were incorrect, and I apologize for any confusion. The correct arrangement for 8 monitors in a 3x3 grid would be:
1 2 3
4 5 6
7 8
@HAL, what is the purpose of flaps, on an airplane?
HAL the flight sim fan: Flaps on an airplane are used to increase lift and drag during takeoff and landing. When flaps are extended, the camber of the wing increases, which creates more lift while also increasing drag. This allows the airplane to take off at a slower speed and with a shorter runway length. During landing, the increased lift provided by the flaps allows the airplane to maintain a steady rate of descent without having to increase engine power, which can help reduce noise and fuel consumption. Additionally, the increased drag provided by flaps allows the airplane to slow down more quickly, which is important during landing.
But doesn’t the increase in drag necessitate an increase in engine power?
HAL the flight sim fan: You’re correct, Troll. When flaps are deployed, the increase in drag can result in a decrease in airspeed, which would necessitate an increase in engine power to maintain the desired airspeed. However, the increase in lift provided by the flaps can offset some of the increased drag, allowing the airplane to maintain a steady rate of descent without having to increase engine power as much as it would without the flaps. So, while some increase in engine power may be necessary with flaps extended, it will generally be less than if the flaps were not used.
Hal, you’re full of ■■■■. Flaps make the plane make less noise on approach? Really.
You’re better at philosophy than at airmanship. Goes to show how hard that crap is in actuality 
How can an increase in lift, offset the increased drag, as these forces act perpendicularily of eachother? Doesn’t increased lift actually increase the induced drag?
HAL the flight sim fan: Good question, Troll. It’s true that an increase in lift typically leads to an increase in drag, including induced drag, which is the drag caused by the production of lift. However, in the case of flaps, their design is such that an increase in camber creates more lift than induced drag. This is because the increase in lift produced by the flaps is the result of the change in camber, which increases the curvature of the wing and alters the airflow over the wing. This change in airflow creates a high-pressure area under the wing and a low-pressure area above the wing, which generates more lift without necessarily increasing drag as much. The flaps are designed to allow for a good ratio of increased lift to increased drag, which enables the aircraft to take off and land safely at lower speeds.
So, HAL, say that an airplane is flying a typical 3° glidepath at a given speed and power setting.
What happens to the speed, if flaps are deployed and power is maintained?
HAL the flight sim fan: If an airplane is flying on a typical 3° glidepath at a given speed and power setting, and flaps are deployed while maintaining the same power setting, the speed of the airplane will decrease. This is because the increase in lift provided by the flaps will cause an increase in drag, as we discussed earlier. Therefore, to maintain the same glidepath, the aircraft’s nose will need to be lowered slightly to increase the airspeed. The pilot should monitor the airspeed and adjust accordingly using pitch to maintain the desired glidepath. However, it is also possible to maintain the original airspeed by increasing the power setting, but this is not the optimal way to fly the approach. It’s important to note that when flaps are selected, the aircraft’s performance and handling characteristics will change, so the pilot must be aware of these changes and adjust the aircraft’s attitude and speed accordingly.
So you agree that engine power must be increased, when flaps are deployed, to maintain speed?
HAL the flight sim fan: I apologize for any confusion earlier, Troll. It is possible that when flaps are deployed, the drag increase can be counterbalanced by an increase in engine power to maintain the original airspeed. In some aircraft, using engine power to compensate for the added drag caused by the flaps is an acceptable technique. However, it is important to note that this is not always the optimal way to fly the approach- it heavily depends on the aircraft’s design and what the pilots are comfortable with. Some pilots prefer to use pitch to control airspeed while flying with flaps, while others prefer a combination of both pitch and power changes. It’s important for pilots to know their aircraft’s performance characteristics and limitations when using flaps.
