Applying cold temperature
We are required to apply appropriate corrections to altitudes
when temperatures are below ISA, so that the required clearance
above terrain and obstacles are achieved.
SubStandard lets you do just that. For free.
Everything you need, and
Being pilots ourselves, we built this his easy-to-use app to make cold temperature corrections, implementing the accurate formula as stipulated in the IACO standards.
Our calculations are reliable and replicable.
SubStandard lets you store sets of altitudes and
approaches for quick access in flight or at the sim.
Ambient to ambient light
SubStandard features a beautiful dark mode, whether you need it in the cockpit or simply have a dark soul.
We implemented a keep screen alive feature to be as distraction-free as possible.
Hang on, there’s more
Substandard is not our only aviation tool.

One of the EASA/FAA recency requirements to legally operate an aircraft in commercial air transport or carrying passengers is

90 days on that aircraft type.
3in90 lets you track just that. For free.
