Instrument Procedures

Prepare for: Partial Panel and Loss of Primary Instruments

Flying and approaching with failed attitude or heading indicators.

Your CFI's syllabus and your airplane's POH come first. This page is a general study aid to help you show up prepared.

What you'll do

  1. Recognize the failure early by cross-checking all instruments.
  2. Cover the failed instrument so it can't mislead you.
  3. Use the remaining instruments: turn coordinator, altimeter, airspeed, compass, and backups.
  4. Use timed or compass turns and expect compass errors (UNOS/ANDS).

The standard you'll be held to

Quoted from the current FAA Airman Certification Standards for each level that tests this.

Instrument Rating ACS (FAA-S-ACS-8C)Task IR.VII.D · Approach with Loss of Primary Flight Instrument Indicators
  • Advise ATC or the evaluator if unable to comply with a clearance.
  • Complete a non-precision instrument approach without the use of the primary flight instruments using the skill elements of the non-precision approach Task (see Area of Operation VI, Task A).
  • Use single-pilot resource management (SRM) or crew resource management (CRM), as appropriate.

Prepare the night before

  • Practice compass turns.
  • Review gyroscopic instruments in the instruments lesson.

Common mistakes

  • Missing the failure because it fails slowly.
  • Over-controlling.

Questions to ask your instructor

  • How will you fail my instruments?
  • What backup instruments does this airplane have?
