Approaching to land at a faster speed will
significantly add to the landing distance required,
and there usually is no provision in the handbook
to predict landing distance at higher approach
speeds. Congratulations, you just became an
unpaid test pilot. You can easily end up needing
more runway than you have available, especially if
your aiming point isn't at the start of the runway,
or the runway is wet or icy, or the airport sits
at a higher elevation. Even if you have plenty of
runway available, it is just considered poor form.
On the other hand, there are times when it is
appropriate to add a measured amount to the
usual approach speed for conditions such as gusty
winds. For example, if reported surface winds
at the airport are headwinds at 11 knots, gusting
to 19 knots you have a gust factor of 8 knots,
calculated by subtracting the steady wind speed
of 11 knots from the peak gust speed of 19 knots.
During gusty conditions, it's recommended to
add half of the gust factor to your usual approach
speed. In the above example, the gust factor is 8
knots, so you would add half of that, or 4 knots,
to the usual approach speed. The extra 4 knots
give you slightly more reserve energy to deal with
the loss of indicated airspeed in case that 19 knot
peak headwind changes to an 11 knot headwind
just as you approach the runway threshold.
SHORT FIELD APPROACH
Some manufacturers recommend a slightly
lower approach speed for short field landings
than normal landings with full flaps. Such a
recommended speed may reduce the margin to
as little as 15 percent above stall speed. Why?
Since the objective in that case is to touch down
at the earliest point and stop the airplane in the
shortest distance, having less reserve energy
helps reduce float and you can bring the airplane
to a stop in significantly less distance at the
slower touchdown speed. On the other hand,
flying this type of approach requires precise
technique, and with less float don't expect a
buttery smooth touchdown. Short field landings
are often firm arrivals. Follow the recommended
speeds and procedures found in your airplane's
operating manual.
BUILDING GOOD HABITS
Good energy management is important when
flying any airplane. Countless accidents have
occurred in light single-engine airplanes because
of poor energy management. The heavier the
airplane, the more time and altitude it takes
to recover from a low energy state. This is why
building good energy management habits early
on will form a good foundation for later. Because
swept-wing aircraft have poor low-speed
