Airspeed indicator calibration
Although your ASI may have been calibrated on a test rig before
installation in the aircraft, errors due to the positions of both the pitot tube
and the static vents may come into effect and need to be checked. If your
formation flying skills are up to standard you could formate on a
certificated aircraft flying steadily at given speeds and note any differences
on your ASI. Carry an observer to take down the numbers and so leave you
free to concentrate on the flying.
If you have a GPS (Global Positioning System) on board, fly into and out of
wind at steady indicated airspeeds noting the ground speed read-out both
ways then divide their total by 2 to obtain the actual airspeed. Don’t forget
to take into account the effect of density altitude.
Envelope expansion
Once you have fitted the stall strips you can start to expand the loading and
flight envelope of your Europa. The important thing here is to do this in
small increments.
Do not simply load it up to gross weight, aft C of G and take off in a 15 kt
cross wind and dive to V
ne
. This would be a totally stupid thing to do.
Extend the speed envelope in 5 kt increments checking for engine/propeller
vibrations, temperatures and pressures etc. Trim to each new speed
confirming that you have sufficient trim and control. With hands and feet
off the controls note any out of trim condition.
Carefully “tap” the control column and rudder pedals to confirm freedom
from vibration or flutter.
