Jeppesen Route manual etc. Flashcards
Category of aircraft speeds on approach (ABCDE)
(Category A) Speed less than 91KT.
(Category B) Speed 91KT or more but less than
121KT.
(Category C) Speed 121KT or more but less
than 141KT.
(Category D) Speed 141KT or more but less
than 166KT.
(Category E) Speed 166KT or more.
On approach the DA (decision altitude) is referenced to?
What type of height?
Also what is the parenthetical decision height referenced to? (DH)
DA(H)
DA = MSL (mean sea level)
(DH) = TDZE or threshold elevation.
FAF (Final approach fix) is designated by?
It is designated in the profile
view of Jeppesen Terminal charts by the Maltese
Cross symbol for non-precision approaches and
by the glide slope/path intercept point on precision
approaches.
GRID MINIMUM OFF-ROUTE ALTITUDE (Grid
MORA)
The Grid MORA altitude
provides terrain and man-made structure clearance
within the section outlined by latitude and longitude
lines. MORA does not provide for navaid signal coverage
or communication coverage.
Grid MORA values derived by Jeppesen clear
all terrain and man-made structures by 1000ft
in areas where the highest elevations are 5000ft
MSL or lower. MORA values clear all terrain and
man-made structures by 2000ft in areas where
the highest elevations are 5001ft MSL or higher.
HEIGHTABOVE TOUCHDOWN (HAT)
The height
of the Decision Height or Minimum Descent Altitude
above the highest runway elevation in the touchdown
zone of the runway. HAT is published on instrument
approach charts in conjunction with all straight-in minimums.
HEIGHT ABOVE AIRPORT (HAA)
The height of
the Minimum Descent Altitude (MDA) above the published
airport elevation. This is published in conjunction
with circling minimums.
MINIMUM DESCENT ALTITUDE (MDA)
Is the lowest altitude specified in an instrument
approach procedure, expressed in feet above mean
sea level, to which descent is authorized on final
approach or during circle-to-land maneuvering until
the pilot sees the required visual references
MINIMUM ENROUTE IFR ALTITUDE (MEA)
The
lowest published altitude between radio fixes that
meets obstacle clearance requirements between
those fixes and in many countries assures acceptable
navigational signal coverage. The MEA applies
to the entire width of the airway, segment, or route
between the radio fixes defining the airway, segment,
or route.
MINIMUM
MINIMUM IFR ALTITUDES (USA)
Minimum altitudes
for IFR operations are published on aeronautical
charts for airways, routes, and for standard instrument
approach procedures. Within the USA, if no
applicable minimum altitude is prescribed the following
minimum IFR altitudes apply.
a. In designated mountainous areas, 2000ft above
the highest obstacle within a horizontal distance
of 4NM from the course to be flown; or
b. Other thanmountainous areas, 1000ft above the
highest obstacle within a horizontal distance of
4NM from the course to be flown; o
MINIMUM OBSTRUCTION CLEARANCE ALTITUDE
MOCA
The lowest published altitude in
effect between radio fixes on VOR airways, off airway
routes, or route segments which meets obstacle
clearance requirements for the entire route segment
and in the USA assures acceptable navigational
signal coverage only within 22NM of a VOR.
MINIMUM OFF-ROUTE ALTITUDE (MORA)
This is an altitude derived by Jeppesen. The MORA
provides known obstruction clearance 10NM either
side of the route centerline including a 10NM radius
beyond the radio fix reporting or mileage break defining
the route segment. For terrain and man-made
structure clearance refer to Grid MORA.
MINIMUM SAFE/SECTOR ALTITUDE (MSA)
Altitude depicted on an instrument chart
and identified as the minimum safe altitude which
provides 1000ft of obstacle clearance within a 25NM
radius from the navigational facility upon which the
MSA is predicated. If the radius limit is other than
25NM, it is stated. This altitude is for EMERGENCY
USE ONLY and does not necessarily guarantee
navaid reception. When the MSA is divided into sectors,
with each sector a different altitude, the altitudes
in these sectors are referred to as “minimum sector
altitudes”.
MINIMUM SECTOR
RUNWAY EDGE LIGHTS (USA)
The runway edge lights are white, except on
instrument runways amber replaces white on
the last 2000ft or half of the runway length,
whichever is less, to form a caution zone for
landings
THRESHOLD CROSSING HEIGHT (TCH)
The theoretical height above the runway threshold at which the aircraft’s glide slope antenna (or equivalent
position) would be if the aircraft maintains the
trajectory of the ILS glide slope, MLS glide path or
charted descent angle
TOUCHDOWN ZONE ELEVATION (TDZE)
The highest elevation in the first 3000ft of the landing surface.
