1.02 VFR Flight Conditions
• MTPs:
– Terminology
– Minimum Visual Meteorological Conditions for
VFR Flight in Controlled Airspace
– Minimum Visual Meteorological Conditions for
VFR Flight in Uncontrolled Airspace
– Day VFR instruments
Terminology
• Visual Flight Rules
(VFR):
– The rules which
apply when flying
by means of visual
reference to the
ground
Terminology
• Instrument Flight
Rules (IFR):
– The rules which apply
when flying by means
of reference to the
instruments in the
cockpit
Terminology
• Special VFR Rules
(SVFR):
– The rules for
operating in
weather conditions
that are less than
VFR within a control
zone where some
aircraft are
permitted flight
under visual flight
rules
Terminology
• Visibility
– The ability, as determined by atmospheric
conditions and expressed in units of distance,
to see and identify prominent unlighted
objects by day and prominent lighted objects
by night
Ceiling
• The lowest height at which a broken or
overcast condition exists; or…
Ceiling
• The vertical visibility when an obscured
condition such as snow, smoke, or fog
exists (500’ in this example)
Terminology
• Flight Visibility
– The average range of visibility at any given
time forward from the cockpit of an aircraft in
flight
• Ground Visibility
– The visibility at an aerodrome as contained in
a weather observation reported by: ATC unit,
FSS, AWOS
Terminology
• Day or Daylight
– TC definition: the time between the beginning
of morning civil twilight and the end of evening
civil twilight
• Night
– TC definition: the time between the end of
evening civil twilight and the beginning of
morning civil twilight

cloud
• 2 C : Uncontrolled Below 1000’
– 2sm visibility, remain clear of cloud
VFR Instruments
• No person shall
operate a glider in
day VFR flight unless
it is equipped with:
– Altimeter
– Airspeed indicator
– Magnetic compass or
magnetic direction
indicator
– Two-way radio with
selectable frequency
(if in controlled airspace)
