The real-world lessons stay in the airplane.

Instrument flying outside the training lesson is a different job: the weather, the clearance, the radios, and the airplane you are actually in. Those lessons belong to that airplane and to your instructor. IFR Suite does not teach them. An article does not teach them either.

What a session is

One procedure, so the picture is familiar before you spend airplane time.

• A departure, until the runway and the first turns are familiar.
• The traffic pattern, until you can describe the circuit.
• An approach, from the initial segment through the missed approach.
• A hold. The entry is direct, teardrop, or parallel, chosen from your heading and from where you are relative to the inbound course.
• An intercept, and a DME arc.

There are more than 9,800 airports and navaids. Glass or round gauges. The instruments stay in English. The session panel follows the language you choose.

There is no radio and no microphone. The app does not play the ATIS, it does not copy a clearance, and it is not a source of charts. Time in the app is not flight time and not instrument time. It is not for a real flight.

Use a short session, then fly the same procedure with your instructor. What the real flight still has to teach you is not in the app.
