Line 3 displays the Minimum Safe Altitude ( MSA )
IMPORTANT : The minimum safe altitude displayed is the altitude defined
by Jeppesen as “Grid Minimum Off-Route Altitude (Grid MORA)”. This alti-
tude is derived by Jeppesen for sectors which are one degree of latitude
by one degree of longitude in size. One degree of latitude is 60 nautical
miles. One degree of longitude is 60 nautical miles at the equator and pro-
gressively less than 60 nautical miles as one travels away from the
equator. One degree of longitude is approximately 50 nautical miles at the
southern most parts of the U.S. and is approximately 40 nautical miles at
the northern most parts of the U.S. The MSA altitude information is con-
tained in the database and is updated when the database cartridge is
updated.
The minimum safe altitude (MSA) provides “reference point” clearance
within these one degree latitude by one degree longitude sectors.
Jeppesen defines a reference point as “a natural (Peak, Knoll, Hill, etc.) or
man-made (Tower, Stack, Tank, Building, etc.) object”. Jeppesen states
the following about the Grid Minimum Off-Route altitude: “Grid MORA val-
ues clear all reference points by 1000 feet in areas where the highest
reference points are 5000 feet MSL or lower. MORA values clear all refer-
ence points by 2000 feet in areas where the highest reference points are
5001 feet MSL or higher”. The KLN 94 displays dashes for areas outside
the database coverage area or for areas where the Grid MORA is not
defined.
Line 4 displays the Minimum En route Safe Altitude ( ESA ).
IMPORTANT : When the KLN 94 is in the Leg mode, the minimum en
route safe altitude is the highest MSA sector altitude from the present
position to the active waypoint, then to the destination waypoint along the
active flight plan. See figure 5-4. When the KLN 94 is in the OBS mode,
the minimum en route safe altitude is the highest MSA sector altitude from
the present position to the active waypoint.
WARNING: The MSA and ESA altitudes displayed are advisory in
nature only. They should not be relied upon as the sole source of
obstacle and terrain avoidance information. Refer to current aero-
nautical charts for appropriate minimum clearance altitudes.
