T-45C TS & ADV BIFP-09
The following procedures assume a single aircraft with functioning radios and
transponder. If you are able to summon a wingman or make a lead change, you can
greatly reduce the problems encountered with an instrument failure. If you lose any
primary navigation or pitot static instruments on an IFR flight, you are required to notify
With each of these failures you should cross-check any suspect instrument indication
with the other cockpit if you are flying dual.
The T-45C display system consolidates traditional analog control, performance, and
navigation instruments into a digital multifunctional electronic array. This system is not
prone to electrical or mechanical malfunction.
In aircraft with exclusive analog instrumentation, pilots must be prepared to manage
multiple instrument failures, including flight director ADI and HSI components. The
T-45C cockpit is equipped with fundamental analog instruments; however, those data
outputs are duplicated within the digital display system. The analog instruments are
available as backups, should digital data sources become erroneous, unreliable, or lost.
Fortunately, the digital system is very reliable.
This workbook examines six categories of possible problems that may occur, which
involve aspects of the T-45C digital display system:
Single MFD failure
Right or left (both cockpits) MFD failure
Total (all four) MFD failure
Blank, missing, incorrect MFD data
MFD push-button failure
Data source failure
It also discusses failure of the following individual instruments:
Standby barometric altimeter
Standby airspeed indicator
