Capability
Gyroscopes
Gyro overhaul at component level — bearings, rotors and balancing, rather than replacement of the whole instrument.
Overview
What we see, and what we do.
A gyro is a mechanical instrument spinning at high speed on small bearings, and almost everything that goes wrong with one is a mechanical problem with a mechanical fix. Noise, precession and slow erection are wear symptoms, not death sentences.
Rotor work and balancing are the parts most shops will not touch, which is precisely why they matter. An overhauled gyro that has been properly balanced runs quieter and lasts longer than one that has simply had its bearings swapped.
Equipment We Service
- Directional Gyro
- Attitude Gyro
- Rate Gyro
- Rate of Turn Gyro
- Vertical Gyro
- Gyro Rotor Assembly
- Gyro Bearing Set
- Gyro Drive Motor
Faults We See Most
- Audible rumble or whine on spin-up
- Excessive precession or drift
- Slow erection after power-up
- Vibration transmitted to the panel
- Failure to hold heading
- Intermittent flag or warning indication
Recognise one of these? Describe what was observed rather than what you think has failed — it is frequently a different unit.
Common Questions
Gyroscopes,
asked in practice.
- My gyro is noisy on spin-up. Does that mean it has failed?
- It means it is wearing. Rumble and whine come from the bearings, and caught early that is a straightforward overhaul. Left alone it becomes precession, then an unreliable indication, then an unscheduled removal at a worse moment.
- What difference does rotor balancing actually make?
- A rotor spinning at high speed slightly out of balance loads its bearings unevenly, so the instrument runs louder and the bearings wear faster. Balancing after a bearing change is the step most often skipped, and it is the difference between an overhaul that lasts and one that comes back.
