What it is
A procedure trainer, not a full simulator
IFR Suite focuses on the mental map of an IFR procedure: visualization, in-flight math, procedural proficiency, and situational awareness. It does not ask you to set up a conventional flight simulator.
Who it is for
Students, flight schools, instrument pilots refreshing their skills, pilots preparing for a checkride, and anyone who wants deliberate IFR practice.
What you need
A phone or a tablet. No extra hardware, no desktop simulator, and no other software.
