Document-No.: 08.510.010.71e/ Revision: 3.10 16
For cross-country flights the QNH can be handled as follows:
(1) After being
switched on /
before start
determine QNH
automatically automatically or
by a long press of
(2) Crossing the
Transition Altitude
set to 1013 hPa /
29.92 inHG STD,
to fly Flight Levels by a long press of
(3) Going below the
Transition Level
determine QNH
automatically, to
fly MSL by a long press of
for approximately
setting the QNH
or manually
using /
(4) Before reaching
the traffic circuit
*)
determine QNH
automatically by a long press of
*)
Even if at (3) the automatic determination already has been performed,
it should be activated again at (4) shortly before reaching the traffic
circuit, as the vertical pressure gradient may deviate from the ICAO
normal atmosphere, what potentially decreases the accuracy of the
QNH determination at the large altitude of (3).
