Roller Landings
Roller landings are usually executed with a final flap setting of LAND. When all
three wheels are firmly on the ground, leave the flaps and elevator trim in
their set position, open the throttle fully and fly the aircraft off at the same
speed as for a normal take-off.
There is no difference in technique if rolling with FULL flap.
At 70 kts. and with a positive rate of climb raise the flap to TAKE-OFF. Select
flaps UP on reaching 80 kts. and 150 ft.
Going Around
When the decision is made to go around, smoothly apply full power and raise
the nose to select the take-off attitude. If the aircraft was trimmed for a low
airspeed on the approach the control column pitch force may be significant.
The aircraft accelerates and climbs safely with FULL flap; raise the flaps within
the speed and height limitations and complete the After Take-off Checks.
Braking Techniques
As soon as the main wheels are on the ground lower the nose wheel to the
runway. Apply the wheel brakes gently at first to avoid locking a wheel; it is
difficult to detect if a wheel is locked from the cockpit.
Increase braking pressure as the groundspeed decreases. For optimum
braking performance, as the nose pitches down with the first braking
application, pull back progressively on the control column whilst keeping the
nose low with increased braking.
Nose Wheel Shimmy
Shimmy is vibration caused by the wheels of a moving vehicle. In an aircraft,
nose wheels and tail wheels are prone to shimmy. It can occur in any axis
and a disturbance in one axis can exacerbate vibration in another.
The IRIS G115E / Tutor T.1 nose wheel has an oil-filled shimmy damper but
problems can still occur if the runway surface is poor, the landing is poorly
executed or there is a technical defect in the nose wheel assembly.
