Air Law

1.3.6.5 Flying under bridges

Flying between bridge pylons and under bridges, power lines, or similar is not

allowed without permission from the Civil Aviation Authority. (Bridge pylons

are considered a single obstacle, even if the distance between them exceeds

300 meters).

1.3.6.6 Transition altitude, transition layer, transition level

VFR flights above the transition altitude must be conducted at a flight level

according to the chart in BL 7-13. However, flights during ascent or descent are
exceptions.

In practice, when passing the transition altitude (3000 feet - except in the

Copenhagen Area, where it is 5000 feet), the altimeter must be set to the

standard setting of 1013.25 hPa.

When this is done, flights are not conducted in "altitudes above sea level," but
in a flight level indicated by the number of hundreds of feet the altimeter shows

relative to the standard setting, e.g., if the altimeter shows 4200 feet, this is
called flight level 42.

VFR flight is prohibited above FL 200, so the highest FL for VFR is FL 195 (see

the section on flight altitudes).

IFR flights are conducted in flight levels ending in "0".
