Skyranger Swift Operators Manual (issue 3)

Limitations 

3.1  Introduction    

This section includes the basic operating limitations for the Skyranger 
Swift.  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.
