Why is aft called aft?
The term ‘aft’ is derived from the Old English ‘æftan’, meaning ‘behind’. It is used to describe the inside rearmost part of the vessel, distinguishing it from the ‘stern’, which refers to the outside rearmost part. The maritime industry has its own language when it comes to naming parts of a ship. The forward of a ship is just as it sounds: It’s the most forward side, at the front of a cruise ship, facing the bow. The rear of a ship, at the direction of a ship’s stern, is called the aft.
Is aft or fwd better?
The forward is subject to the most movement out of anywhere on a ship. And the higher the deck, the more pronounced that rolling and swaying motion tends to feel. Movement at the aft is a bit less drastic than the forward, but still isn’t the most stable place for those who are prone to seasickness. If you are keen on a view out over the ship’s wake and the potential for scoring a larger veranda (and don’t mind the potential for some extra vibration), then the aft of a ship is probably the right move. Keep in mind, too, that there is a case to be made for forgoing both sides and simply booking a midship stateroom.
Why is cruise speed faster with aft cg?
Forward vs. The relationship between your aircraft’s performance and CG location is simple: by moving your CG forward and aft, you change the amount of tail down force and lift you need for stable flight. When you create more lift, you create more induced drag, and your performance goes down. While a forward CG enhances stability, it also increases drag and stall speed. Conversely, moving the CG aft may reduce drag and stall speed, but at the cost of stability. This trade-off is critical for pilots to understand, especially when managing fuel efficiency and stall recovery.Forward CG results in a more stable aircraft, potentially even so stable you won’t be able to effectively control it. Aft CG results in a less stable aircraft, making it more manoeuvrable, but if you go too far it will be unstable and impossible to control.The aft CG limit is the most rearward position at which the CG can be located for the most critical maneuver or operation. As the CG moves aft, a less stable condition occurs, which decreases the ability of the aircraft to right itself after maneuvering or turbulence.Before you go throwing everything possible into the baggage compartment, consider this: while having an aft CG definitely improves performance, in most light aircraft, the difference in will be a few extra knots of airspeed, and a little better climb rate.
What is better, aft or forward cg?
Remember, a forward CG can result in higher stall speeds and increased fuel consumption. So if you’re planning a flight with no need for extra stability, it might be worth managing your load to shift the CG slightly aft for better efficiency. Always ensure your CG is within the aircraft’s limits for safe operations. Key Differences: -Forward CG: More stable, slower cruise speed, higher stall speed. Aft CG: Less stable, higher cruise speed, lower stall speed.An airplane with an aft CG performs better than an airplane with a forward CG, but often suffers poor handling characteristics, especially in stall recoveries where it will have an increased tendency to enter a spin if the stall is uncoordinated.
