FAA Instrument Ground Instructor IGI foundations cheat sheet

Specify inlet, drain and static-source conditions before predicting indications.

A blocked inlet with an open drain differs from a fully sealed pitot line.

Identify shared sensor and power dependencies before calling displays independent.

Scan links attitude, power and performance for the actual maneuver.

Ground reasoning does not establish practical recovery proficiency.

An IGI rating has ground-training privileges, not independent flight-instructor authority.

Filing an IFR flight plan alone is not an ATC clearance.

US radio-failure altitude selection uses the highest applicable value under the IFR branch.

Descent below minima requires more than recognizing an airport light.

Actual chart, clearance and aircraft limits govern missed-approach decisions.

A small dew-point spread indicates proximity to saturation, not certainty of existing fog.

Compare environmental and parcel lapse rates using the supplied assumptions.

Hemisphere and system geometry matter to wind-shift claims.

Visible cloud or radar boundaries do not contain every hazard.

Decode day, time, units, trends and scope before drawing conclusions.

A radial, bearing, selected course and aircraft heading are different quantities.

TO/FROM is not simply a report of aircraft nose direction.

DME is slant range, including the vertical component.

A pressure altitude is not automatically exact geometric separation.

Published instrument procedures take precedence over a generic display shortcut.

Define behavior, conditions and criteria before selecting a teaching method.

Recall, understanding, application and correlation require different evidence.

Diagnose the cause of an error before prescribing repetition.

Distinguish assessment reliability from validity.

Ground teaching authority does not itself authorize flight instruction or pilot privileges.
