3. Limitations
3.1
Introduction
.
This section includes the basic operating limitations for the Skyranger. The
full limitations are contained in Homebuilt Aircraft Data Sheet (HADS) HM4,
which is used by the Inspector at Annual Permit renewal to ensure, amongst
other things, that the correct limitations are placarded in the cockpit.
3.2
Units.
When noting limitations, it is important to ensure that the limitations which
you are using use the same units and calibrations as the instruments in the
cockpit. The limitations shown below use knots CAS (Calibrated Airspeed);
your aircraft may have an instrument in mph, and in any case will read IAS
(Indicated Airspeed). The difference between IAS and CAS is basically the
accuracy of your Pitot-static system. The IAS limits for your aircraft were
determined when the aircraft was test flown, and are shown in Annex A to
this manual. There will also be a placard in the cockpit, however space is
allowed below for you to insert the IAS limitations and calibration details for
your aircraft.

Unless all errors are less than 2 knots, a copy of this calibration card must be
displayed in the cockpit near to the ASI.
