Thank you for a great video. Quite informative. I am not working in the aviation industry, just interested in aircrafts. I have a question. From your videos, what I understand is that, the main flight controls are operated by pure physical muscle power, isn't it? It is not assisted by hydraulics? In the age of power assisted steering in cars, why are the flight controls are not power assisted? I assume in larger aircrafts, the controls are operated by hydraulics. So, up to which size of aircrafts are the flight controls not assisted?

Good work captain, thanks for the educational video, at 8:30 does this mean both props are rotating in the same direction? which one? and does it feel like a Cessna in take off? I mean do you have to apply right rudder during the take off roll? thanks

@FlywithMagnar 2 жыл бұрын

Both propellers are rotating clockwise when viewed from behind. As I say in the video, the rudder trim is set to neutral at take-off. The ATR has a natural tendency to go straight on the runway. When you rotate, there's a slight yaw to the left, but most pilots do not even notice it. Once established in climb, the aircraft is going straight. As the speed increases, there will be a need to trim the rudder to the right.

Hi captain! Amazing video as usual. In case of pitch disconnect, is there a way to fix which control column will be PF, or it a random chance ?

@FlywithMagnar 2 жыл бұрын

When both elevators are free, it's up to the pilots to decide who shall be PF.

@spinbirdman 2 жыл бұрын

Usually a pitch disconnect is manually done after an elevator jam, in which case, the pilot on the unjammed side will need to be the PF.

Hello, Captain. Why do we have the 180 IAS limit for ELEVATOR JAM and PITCH DISCONNECT? Is it to prevent structural damage to the control surfaces?

@FlywithMagnar 5 ай бұрын

No, it has to do with the controllability of the aircraft. When you have only one functioning elevator, you have reduced controllability, and the higher the speed, the higher the control forces.

@tovip2697 2 жыл бұрын

Hello Magnar, what a wonderful video! The rudder is quite complicate, but it seems to work very fine in terms of pilot comfort. I think you did a very good explanation for the working principle of the rudder. A little question came up during watching your explanations regarding the rudder: When you move both yaw trim switches to position "NOSE RH", does the spring tab move to the left (when viewing the rudder from top) or right, and what would be the indication? It is a bit confusing to me, since the switch is about the "aircraft nose", and the trim indicator shows the "motor displacement". From my understanding the trim tab must move left to yaw the aircraft to the right... *total confusion coming up*

@FlywithMagnar 2 жыл бұрын

When you move the trim switches to the right, the spring tab moves towards the left. This creates an aerodynamic force that moves the rudder towards the right, which in turn creates an aerodynamic force that moves the tailfin to the left, causing the nose to turn to the right. The deflection of the spring tab depends on two factors: Trim tab motor displacement and the airspeed.

@tovip2697 2 жыл бұрын

@@FlywithMagnar Thanks for confirmation. So the indicator in case the switches are moved to right ALSO point to the right (despite the trim tab is travelling to the left)?

Greetings Captain, I need ask a few questions to assist in understanding the system. Specifically, 1) With autopilot and yaw damper engaged . To trim the rudder in the yaw axis is the autopilot doing the trimming on the spring tab or only the rudder or both i.Or is it the yaw damper only providing the signals? 2} In manual flight when we move the yaw trim control switches are we acting on the spring tab only or on the rudder and spring tab simultaneously? I am somewhat confused. Many thanks

@FlywithMagnar Жыл бұрын

Rule #1: The rudder trim acts on the spring tab. The spring tab acts on the rudder, and the rudder deflection increases with the airspeed. Rule #2: To use the autopilot, the yaw damper must be engaged. In aircraft without glass cockpit, it is the pilot who acts on the rudder trim reagerdless of the status of the yaw damper and autopilot. In aircraft with glass cockpit (600 version), the rudder trim is automatic as long as the yaw damper is engaged.

Great video! I was just wondering why are the aileron indication displayed in white while the rudder trim indication is displayed in green in Autopilot for the 600 variant?

@FlywithMagnar Жыл бұрын

When the Autopilot (AP) is engaged, the aileron trim indicator is white, indicating it is inhibitted. When the AP is disengaged, the aileron trim indicator is cyan, indicating it can be operated manually. When the Yaw Damper (YD) is engaged, the trim indicator is green, indicating the rudder trim is automatic. When the YD is disengaged, the trim indicator is cyan, indicating it can be operated manually. Note: The AP can only operate when the YD is engaged.

Hello captain¡ in case of flaps asymmetry or flaps unlock that you have to land with reduced flaps, how do you decide if it’s going to be flaps 15 or flaps 0 table¿

@FlywithMagnar Жыл бұрын

Asymmetric flaps: Use the speed for indicated position. If it's between two positions, select the one that gives the highest approach speed. Flaps unlock: The flaps is at 0 position.

How do the elevator and rudder control cables/rods pass through the aft. pressure bulkhead without leaking cabin air or abrading?

@FlywithMagnar Жыл бұрын

Pressure seals are installed where cables (or rods) move through pressure bulkheads. The seal grips tightly enough to prevent excess air pressure loss but not enough to hinder movement of the cable. In other words, there's a small air leak, but this is acceptable. Reference: www.aircraftsystemstech.com/p/aircraft-rigging-aircraft-rigging.html

When you have a rudder mistrim, you must disconnect the autopilot and trim the rudder manually. In case of engine failure or shut down during cruise, you should reduce the speed to less than 180 kt to activate TLU low speed mode.

@FlywithMagnar 2 жыл бұрын

In the late 1980s, when ATR 42 was developed, the company considered that the market for STOL aircraft to be too small to be commercially viable. They were right because de Havilland Canada made excellent STOL aircraft, which sold in small numbers. However, when the Dash 8-100 and -200 are no longer are in production, there's a growing market for a 50-seater that can operate from 800 m runways. Therefore, modifying an existing design makes sense today.
