Check/test display system 1.4.18.4.1
A. T-45C BIT system
1.
Four types of BIT
a.
Power-up BIT (PBIT): The power-up
BIT (PBIT) is the most extensive and is
automatically initiated when electrical
power is applied with weight-on-wheels
b.
Initiated BIT (IBIT)
(1) The Display BIT is a combination
Fig 1: Weight-On-Wheels BIT
of an IBIT of the DEU and an IBIT
Display -- Engine Operating
and Manual BIT (MBIT) of the
HUD and MFD
(2) The initiated BIT, IBIT, is similar to
the PBIT but it is less extensive.
The IBIT must be initiated by the
pilot and can only be performed
with weight-on-wheels because it
interrupts the normal operation of
the equipment
c.
Manual BIT (MBIT)
(1) The manual BIT (MBIT) may be
performed on the following
equipment: Data Entry Panel, IFF,
Multi-Function Display, TACAN,
UHF/VHF, VOR/ILS, and Yaw
Damper System (YDS)
(2) The MBIT interrupts the normal
operation of the equipment and
requires the pilot to observe the
results because they may not be
reported on the BIT display
