MANUAL POSITION UPDATE function
This function may be used on to update manually the FMGC position.
It should be used in exceptional cases when GPS is not available or not
installed. It is available on ground or in flight.
Caution:
Unless the update is performed precisely over an identified
position, this procedure is likely to introduce a greater error
than that which it is intended to correct.
Any NAVAID, WPT, RWY or AIRPORT which can be precisely overflown
may be used to update position.
In the following example, a position error is detected: raw data shows
LMG 036°/5.8 NM while map and BRG/DIST shows LMG 102°/23.4 NM.
An UPDATE position overhead LMG VOR will be performed.
