9/ Ten spot landings
There were daily landing contests during the International
Air Rally 2004 held in eastern Canada in July. At the destination airports two
white lines were drawn across the beginning of the runway 100 feet apart. To
score, the aircraft main wheels had to touch down between the lines …and stay
down.
Each rally team had a minimum of two crewmembers, a pilot
and a navigator. These were competitive aviators, most with plenty of flying
experience.
It was fun to watch the landings. Each pilot seemed to
have his or her own technique. Here, tongue-in-cheek, are the ten most
interesting ones. For the sake of your airplane, please don’t try these at
home.
1/ Top Gun Arrival
For this approach, the pilot lowered full flaps, slowed to
minimum speed, set up a rapid sink rate and then added a handful of power to
control the angle of the approach. As the pilot neared the marks, he or she cut
the power and rode the airplane into the pavement.
A Top Gun Arrival could be spotted by watching for the
pilot’s face pressed against the inside of the windshield. As the airplane
ploughed nose-high toward the runway, the pilot’s jaw would be clinched and
the eyes would be staring transfixed at the lines. The accuracy of this method
was good but without an arrester cable and a hook, the airplane often bounced
out of the box.
2/ Let Gravity Do It
For this one, the pilot executed a power off, full flap
approach to a perfect, full-stall landing over the spot.
The success of this technique varied. Sometimes the
landing was completed ten feet above the runway, sometimes ten feet below. The
accuracy was not as good as the Top Gun Arrival but the rebounds were smaller.
3/ The Mother-in-law Approach
During the spot landings, if both crewmembers were pilots,
one would fly and the other would jump up and down and yell.
"You’re too high! Too slow! Add power! Dump the
flaps! Nose down... you missed."
The score on this technique depended on where the airplane
was in its cycle of gyrations when it arrived at the spot.
It was easy to see a mother-in-law approach coming. The
airplane would follow a roller-coaster path to the runway and the crewmember in
the right seat would be flailing against the seat belts.
4/ The Two-Pilot Tango
This technique required two domineering pilots and dual
controls. The airplane would zigzag its way to the runway with two red faces
grimacing in the windshield. Each pilot would be fighting the other for control.
Most of the time, they missed the mark. Sometimes they had trouble hitting the
runway.
5/ The Three-Pilot Tangle
This was a combination of the Two-Pilot Tango and the
Mother-in-law Approach. Two pilots in the front seats would be fighting for
control while a third pilot in the back seat screamed at them. The teams using
this technique had trouble finding the airport.
6/ The No-Pilot Approach
Sometimes two pilots thought that the other was flying.
The airplane would approach the lines in a gentle descent. The pilots would turn
and face each other with surprised looks and mouths wide open.
Several teams landed on the spot using this technique.
7/ "Have Arrived"
For this one, there would be no faces in the windshield.
Both team members would have their heads down watching the GPS, which had been
programmed to guide them to the spot.
This technique rarely worked. When the GPS flashed
"Have Arrived" the pilots would look up in time to see the nosewheel
careen off the spot followed by the airplane porpoising down the runway.
8/ Let George do it
Some crews coupled their autopilot to the GPS for the
approach. The result was either the same as the "Have Arrived" landing
or worse if there was any crosswind. The autopilot crabbed on final to correct
for the drift. The airplane would be tracking to the spot but the nose would not
be pointed at it. Often the pilot would push on the opposite rudder to
compensate. The autopilot would then add opposite aileron. The pilot would push
harder on the rudder.
By the time the airplane arrived at the spot, it would be
in a cockeyed forward slip. The pilot would disengage the autopilot to land; the
airplane would then obey the full rudder command and yaw wildly the other way.
The landing was known as "The Skippy".
9/ The Wheelbarrow Waltz
Sometimes the less experienced pilots would forget one
element of their approach. They might set up a descent but forget to slow down;
or do a perfect approach but forget to flare out; or fly their approach with the
power on all the way to landing. The result was always the same. The airplane
landed nosewheel first, often in the box. The fun part came next when the pilot
tried to steer the airplane on the runway with the mainwheels still in the air.
10/ The Slam Dunk
Some experienced pilots applied a new landing technique.
"The Slam Dunk" involved a low speed, flaps down, power on approach.
When the airplane was nearing the spot, the test pilot would retract the flaps,
cut the power, raise the nose and open the doors. The result was a combination
of the Top Gun Arrival and the Let Gravity Do It. If there were other pilots in
the airplane, they would be screaming.
It’s fun to joke but there are serious reasons for
pilots to have spot landing skills. Similar techniques are used for touching
down accurately on a short strip, on an off-airport landing or during a forced
approach.
Besides you might like to win the landing trophy at your
local airport.
To put the difficulty in perspective, remember that an
airplane traveling at 75 mph is covering more than 100 feet per second. If you
have to make adjustments as you approach the spot, it’s too late. Given the
pilot’s recognition time, reaction time and the airplane’s reaction time and
its speed, you have to be set when you are 500 feet from the target, or you
might as well go around.
The best way to gain proficiency is by practising.
Try landing in the space between two runway centre lines
at your home field. Pick a set of lines at the 1,000-foot mark. You’ll see
that it’s harder there than touching down accurately where you normally land.
Be careful. There is a strong tendency to concentrate on
the spot and ignore little things like airspeed, crosswind drift and height
above the runway. Take along a brave instructor or a safety pilot who can
scream.
When you think you’re good, try it with the power idling
from circuit height (except to warm the engine). After you master that, quit for
the day and then try it in different conditions, then at different airports and
then in different airplanes. Now you might be ready for the landing contest in
the next International Air Rally.
In the interest of advancing pilot skills and improving
scores in contests, I offer the following tips on spot landings during contests:
1/ Practise, as outlined above;
2/ Decide which crew member is performing the landing;
3/ Duct tape the rest of the crew on board. Cover their
mouth and eyes, and bind their hands and feet;
4/ Land the airplane, rubber side down and main wheels
first.
Good luck!
