Talk:Attitude indicator

message: "If the horizontal lines and the dot are above the horizon line, the aircraft is gaining altitude and is pitched upward."
just because the nose is pointing upward it does not  mean you are gaining altitude, you also need enough airspeed am i right? (flight simulator user :) )
:I'm not a pilot, but I believe you're right. Usually, the nose must be pitched slightly upward to maintain level flight, at least in an airplane. It might have to be slightly down, however, in a helicopter. Those who know better should provide some input, either here or at the appropriate spot in the article. 76.21.8.213 (talk)
:Most aircraft require a nose up pitch attitude of 1 to 2 degrees to maintain a level flight path and normal cruise speed. If you increase either the pitch or the speed (or both) then the aircraft will climb. (I am a pilot btw) 92.24.141.28 (talk) 16:34, 10 May 2009 (UTC)
thread_title: Pitch vs. level flight

message: Pitch and bank are ANGLES.  Roll is a RATE (degrees/time).
The AI shows pitch and bank only, not roll.
Roll rate can be implied by the pilot by watching how fast the bank angle changes,
but the roll rate is not directly shown on the AI.
The (older) turn indicator shows turn rate only.
The modern turn coordinator shows turn rate + roll rate.
As you enter a turn, the plane has a high roll rate and low turn rate.
When the turn is established (and held with constant bank angle) roll rate is zero
and the indicator shows turn rate + (zero) roll rate.
Note that if the aircraft is rolling about the longitudinal axis and not turning,
the turn indicator will read zero, while the turn coordinator will register the changing roll rate.
A standard rate turn is 360 degrees in 2 minutes (for slower aircraft).
The turn coordinator (or turn indicator) has index marks for a standard rate turn.
A quick formula for bank angle to effect a standard rate turn is:
15% of airspeed (in knots) = bank angle.
For 90 Kt. bank angle = about 13.5 deg.
For 120 Kt. vabk angle = 18 deg.
The AI is used to set bank to a specific angle, then the turn coordinator
is used to monitor the quality of the turn via roll rate.  — Preceding unsigned comment added by 69.239.146.121 (talk) 19:07, 2 June 2013 (UTC)

message: So an Attitude Indicator does NOT work by measuring the direction of gravitational pull?  I thought it was a free-floating ball with the bottom full of something heavy.  Wouldn't a gyroscope become inaccurate due to the curvature of the Earth? Algr (talk) 01:09, 19 October 2021 (UTC)
