Altitude must be pre-flight cross-checked by comparing the aircraft's
altimeter with the GPS altitude displayed on the EFB application.
9.5 Initial Use After Purchase
Having set up your Sky Echo in accordance with the instructions above,
before flying it for the first time you will need to achieve an initial GPS fix in
your location. This first fix will take much longer than in subsequent use as
the Sky Echo needs to update its satellite Almanac to determine which are
'in-view' at your location. Having built an Almanac the Sky Echo can
disregard satellites that will be over the horizon and fix rapidly thereafter.
To achieve this first GPS fix, place your Sky Echo in an outdoor location
with a clear view of the sky above it. Whilst it can achieve a fix if affixed to
a window, this cannot be assured inside a building. Please be patient and
allow the fix to complete; a change of hemisphere from the Sky Echo's
point of manufacture could require up to an hour for it to rebuild its
Almanac.
