FMC Navigation Check

If the IRS NAV ONLY, VERIFY POSITION, or UNABLE REQUIRED NAV

PERFORMANCE - RNP message is displayed in the scratch pad, or course

deviation is suspected, accomplish the following as necessary to ensure navigation

accuracy:

Actual position

Determine and compare with FMC position

Determine actual airplane position using raw data from VHF navigation or

ADF radios.

If radio navaids are unavailable:

FMC position

Compare with the IRS position

Use the POS SHIFT page of the FMC CDU. If the two IRS positions

are in agreement and the FMC position is significantly different, the

SP.11.12

FMC position is probably unreliable. The POS SHIFT page may be

used to shift FMC position to one of the IRS positions. This is

accomplished by line selecting the IRS or radio position and then

pressing the EXEC Key.

Actual position

Confirm with ATC radar or visual reference points.

Navigate using most accurate information available (continue to

monitor FMC position using VOR/ADF raw data displays on

non-flying pilot's navigation display).

CAUTION: Navigating in LNAV mode with an unreliable FMC

position may result in significant navigation errors.

Navigate by conventional VOR/ADF procedures, radar vectors from

ATC, dead reckoning from last known position, and/or use of visual

references.
