The power required at low altitude for a given IAS is
- unchanged with altitude.
- higher.
- lower.
kspyroglou asking:
How is that possible? The air is more dense, therefore the drag is increased, thus the thrust (power) should be increased
The vertical fin of a single engined aircraft is
- parallel with both the longitudinal axis and vertical axis.
- parallel with the longitudinal axis but not the vertical axis.
- parallel with the vertical axis but not the longitudinal axis.
kspyroglou asking:
Can someone explain?

- 104 nautical miles
- 100 nautical miles
- 96 nautical miles
huly asking:
My math says 100NM. Am I wrong?
Longitudinal dihedral (decalage) is:
- The angle of sweepback between the wing leading edge and a line perpendicular to the fuselage centreline
- The upward angle of the wings relative to the horizontal, which provides lateral roll stability in a sideslip
- The difference in angle of incidence between the wing and the tailplane — it contributes to longitudinal stability

Please explain. Thank you
