Why Ground Reference?
One of the weakest parts of flight instruction is the failure
of the instructor to let the student know the 'why' of some of
the maneuvers as they relate to actual flight operations. Ground
reference is but one of these areas of weakness. Every ground
reference maneuver has the potential of being applied in a real
situation in the vicinity of an airport. We perform the four basics
close to the ground so that the student can become familiar with
the visual effects caused by ground movement under the aircraft.
Again, this perception is part of the approach to landing. The
apex of all ground reference maneuvers is the landing.
Flying relatively close to the ground greatly reduces the options
you have in event of an emergency. It's not all bad since in case
of a fire you can get to the ground more quickly. Select your
area for ground reference in a sparsely inhabited area with plenty
of emergency fields. At altitude we have always cleared prior
to every turn. There is no reason not to clear for ground reference
turns and every reason to continue what should be an ongoing habit.
Once you have cleared, look over the nose during the turn.
As with airports you are learning to divide your attention
between the ground and the airplane while maintaining control.
If you do not properly divide your attention you will have difficulty
maintaining a constant altitude and the desired ground track.
At 4500' a hundred-foot altitude deviation is not as significant
as it is at 500'. As changes in altitude and flight path occur
you will be making cockpit adjustments using the division of attention
skills required close to the ground. Ground reference maneuvers
are performed to increase your comfort level with ground proximity
before you begin intensive training with landings.
Any inability to understand and perform ground reference will
appear again during the instructional phase on landings. Winds
are never, but never, what ATC says they are or will be. The performance
of the airplane in relation to the ground track and speed tells
you the wind. When the airplane does not point where it is going,
it is because of the wind. When the groundspeed on a stabilized
approach (correct airspeed) is seemingly too fast or slow, high
or low, it is because of the wind. You must learn to fly airspeeds
during landing approaches and interpret any variations in pattern
and approach angle as due to wind.
When you have soloed and have an opportunity to practice ground
reference on you own you enter a new world of practice. Only practice
of the right kind will lead you beyond rote performance to competence
and finally to confidence. You may recognize that you are having
difficulty, and you may not. (Agnosia: You don't know what you
don't know) Contact the instructor and talk/walk through the maneuver
to make sure you understand the mechanics involved. This may solve
the problem, but if it doesn't, a flight lesson is going to be
the most economic solution. There is nothing worse you can do
in flying than practicing a procedure incorrectly.
Cross country flying not so apparently utilizes ground reference
skills To fly a given course in any wind you will be required
to make heading adjustments and bank adjustments. The higher altitudes
of cross country make ground track adjustments more difficult
to determine. The more readily you can make heading corrections
for a desired ground track the more efficient will be your cross
country flying. Some examiners hold a pilot to 1/8 mile of his
selected course. ( Good reason to make a 270 takeoff departure.
This way you can start your time and course directly over the
airport.
