IRS Reversions
IRS reversions depend on how many inertial reference systems are
installed. With two IRSs, either IRS can be transferred to the other side.
With three IRSs, the third IRS can be transferred to one or both sides.
The applicable EADI and EHSI annunciators are as follows:
D Dual IRS -- When IRS reversion is selected, the source side displays
IRS in an amber box, as shown in Figure 4--14.
