5.11 THE AIR DATA PAGES
The Bendix/King KAD 280 and KAD 480 air data systems
as well as specific models of Shadin Company air data
systems may be interfaced to the KLN 90B. When inter-
faced with one of these systems, the KLN 90B will display
real time air data parameters such as true airspeed (TAS),
static air temperature (SAT), total air temperature (TAT),
Mach number, density altitude, and pressure altitude.
With a TAS input from an air data computer and a compat-
ible heading input, the KLN 90B will calculate and display
real time wind data (magnitude and direction).
NOTE: Heading information inputs to the KLN 90B must
be in a format which is different than available from most
mechanical compass systems, including the Bendix/King
KCS 55A (KI 525A with bootstrap heading synchro) and
KCS 305 compass systems. However, the Bendix/King
KA 90 adapter as well as the compatible Shadin air data
system will convert three wire analog heading information
from these mechanical systems into the proper format.
Bendix/King electronic HSIs such as the EHI 40 and EHI
50 directly provide heading information to the KLN 90B.
The Other 9 and Other 10 (OTH 9 and OTH 10) pages are
used to display air data information if both a fuel manage-
ment system and an air data system are interfaced to the
KLN 90B. If there is no fuel management system, air data
information is displayed on the Other 5 and Other 6
pages. If there is no air data system interface, these
pages are not displayed.
NOTE: These air data pages receive inputs from air data
sensors and display real time air data information. They
are independent of the CAL 1, CAL 2, and CAL 3 pages
which rely on manual pilot inputs to calculate air data infor-
mation.
