# The instrument that show the attitude in the F-16 cockpit in a dive glide slope but nose up attitude what will show? [closed]

An F-16 Fighting Falcon is nose up at 25 degrees angle of attack (AoA) and unable to keep the level flight path but it is in a $$600$$ feet per minute dive slope. Does the attitude direction indicator (ADI) show more of the sky or more of the ground?

• Angle of attack is not a variable in the pitch attitude of the airplane. You can be at any AoA at any pitch attitude. What is the power setting? Jul 20, 2023 at 16:45
• The power setting is on the left side of the curve ,but I'm interested only the attitude showed on ADi ,regardless of the /climb /dive (here)velocity. Jul 21, 2023 at 5:16
• 600 FPM is 3 degrees or so flightpath below the horizon at normal approach speeds; it would be perhaps 1 degree below the horizon at 250 knots. So if your flightpath is -1 to -3 and your AoA is +25, your pitch can be estimated, as long as one assumes thing like wings level and some sort of reasonable airspeed. (If assumptions can include unreasonably slow forward speeds, ie a VTOL hanging in the air with barely any forward or vertical speed, then everything is "possible", if pretty wildly hypothetical.)

• "An F-16... is nose up at 25 degrees angle of attack (AoA)" -- this sentence is confusing. The implication is that "25 degrees" is meant to specify exactly how "nose up" the plane is. It sounds like you meant to say the pitch attitude is 25 degrees. Did you? Or did you mean to say something like "The nose is above the horizon at some unspecified angle, and the angle of attack is 25 degrees" --? Pitch attitude and angle of attack are two completely different things. Or by "is nose up" did you not actually mean that a/c was in a positive (nose-up) pitch attitude? Please clarify.

• (As long the a/c really "is nose up" relative to the horizon, the answer seems obvious.) On the other hand if the question is only meant to specify that the a/c is nose-up relative to the flight path, then you really need to say that explicitly, because that's not what we normally mean by "nose up". As it stands now the question is confusing. Jul 22, 2023 at 11:42
