Turn and Slip or Turn Coordinator Instrument Removed
If the electric turn and slip indicator or turn coordinator is to be removed, then the
existing Attitude indicator must be relocated to the empty turn and slip instrument hole.
Note: Aircraft with a rate-based autopilot – the autopilot is using the turn and slip
instrument for roll input and therefore this instrument must not be removed.
Turn and Slip or Turn Coordinator Instrument Retained
No Flight Director display - The existing attitude indicator if used as an attitude source to
the autopilot (no flight director display, and no EA100 installed) may be repositioned to
any position in the instrument panel, including the co-pilot side, as the turn and slip or
turn coordinator is retained in its original location as part of the backup attitude solution.
Flight Director display - If the existing attitude indicator includes a flight director display
then it must be relocated to a position within the pilot’s primary maximum field of view in
accordance with FAR 23.1321(a). The requirements are ±35 degrees from the pilot’s
centerline horizontally (± 21 inches from centerline as defined by AC 23-1311-1b) to an
area just below the basic T configuration to the glare shield vertically (see Figure 4-2
below). The EFD1000 E5 does not display flight director information.
