Jeez, this is so intense?

If anyone of you can find the time and/or inclination to help with the
Qs themselves, I acknowledge thanks gratefully. Ignore Q12 of course

What a bizarre collection of questions. And poorly worded too. Surely
this isn't a literal transcription from the actual written exam?

And yes, there's a lot to learn before one is granted a pilot certificate.

Bank angle and roll rate.


Rate of turn only. Cross control, and you have bank & roll rate with no
turn.

No, the "needle" of "needle and ball" provides rate of turn only. The
turn coordinator provides an initial indication of rate of roll. That's
the difference between the two instruments.

It's not clear what you're correcting. You are right that I should have
written "turn rate" instead of "bank angle". It was kind of late. But you
do also get roll rate from the turn coordinator. It's not "rate of turn
only".

The turn coordinator senses roll and yaw. It exaggerates the roll and thus
indicates a standard rate turn before the aircraft is actually banked that
far. The exaggeration is good for an autopilot pickup because it reduces the
inherent lag in autopilot systems.

It is not good in turbulence because it makes it easy to over compensate.
That is why rate based autopilots like the S-Tec are not as smooth as
attitude based autopilots in turbulence. There are still arguments about
which is better, a turn coordinator or a turn and bank. A turn and bank is
better in turbulence. A turn coordinator is easier for a student to
visualize, although they seldom know just what they are seeing-----For
instance, a TC will indicate a bank on the ground when turning, when there
is clearly no banking going on.
