How is this quadcopter so stable with props so close to CG/Fuselage? [migrated]
How can this quadcopter be so stable having its propellers so close to the center CG. Isn't this suppose to affect its balance?
Here is an image with a top and bottom view, you can see how the props ...

Why was the noseless Sikorsky S-22 stable enough to fly?
Many airplanes have a fairly heavy nose protruding in front of the wing and a light tail, to put the center of mass forward enough to provide pitch stability.
But photos of the 1913 S-22 show that in ...

Is the neutral point the point where the airplane rotates about? [duplicate]
Is the neutral point the point where the aircraft rotates about and not the CP?
Consider you balance an RC-Airplane
on your fingertip.
Then you have the CP, where the sum of momentums is zero. Now ...

Are there weight sensors in each wheel so the computer can calculate the CG directly, without info about the cargo? [duplicate]
Or does the captain still have to do a pre-flight calculation involving center of gravity?

CG limits of Piper Pawnee?
In looking at a Piper Pawnee I found in the cockpit most of the expected documents, including a POH and a signed-by-A&P weight and balance sheet for that particular aircraft. The POH lists the max ...

Why does forward CG decrease controllability/maneuvarability?
Why is a larger elevator input required to change the pitch of an aircraft with a more forward CG? I would think intuitively that the farther forward the CG, the greater the arm between the elevator ...

Can passengers boarding back first tip back an airplane? [duplicate]
I came across this image and don't have any details nor do I know the exact reason, but it made me ask myself if passengers boarding to the back first can tip back an airplane?

Is there a reason why the vertical lines of some airplane envelope graphs are not parallel?
I am working on a project to develop an easy solution for mass and balance generation for my aviation club. (First example below)
I checked the Graph of a PA-44-180 from the POH and wondered why piper ...

Is the interpretation of "54 knots CAS at the aircraft’s maximum certificated takeoff weight and most critical center of gravity" subjective?
The newly proposed MOSAIC regulations state in §?61.316
(1) A maximum stalling speed or minimum steady flight speed without
the use of lift-enhancing devices (V S1 ) of not more than 45 knots
CAS, ...

Does CG change airspeed in a descent or glide?
If the CG of an airplane moves forward, would it fly a faster or slower airspeed in a descent?
Usually during a descent or landing, you'd use pitch to change airspeed and power to control descent rate....

Are there additional structural measures in airliners with asymemtrical seating arrangements?
I was recently flying onboard an A220 and was surprised by the asymmetrical five abreast seating arrangement.
Are there any structural measures (e.g. counter weights, ...) to balance out the aircraft ...

Aircraft CG limitations: what drives constraints beyond max weight & a single forward (and aft) limit?
In a chart like the one below, limitations on the max aircraft weight (upper horizontal line), forward-most CG (left vertical line), and aft-most CG (right vertical line) are fairly easy to understand....

Is this method to calculate a biplane's center of gravity using 57% of the biplane's gap and 23% of each wing's MAC correct?
Once you have the MAC for both wings and the CG balance point as a percentage of the MAC. connect the two CG positions with a line. Measure up between the wing Gap distance and place your center of ...
