What is the primary driver of the TNMCS rate?
Spare parts availability
What is the focus of the 4-/8-/12-hour fix rates?
Examining the repair process management
What may indicate a lack of thorough troubleshooting or inordinate pressure to commit aircraft to the flying schedule?
A high R/R rate
What is the relationship between the R/R rate, break rate, and fix rate to NMCM?
A strong correlation between the three rates may indicate problems
What is the key to minimizing downtime according to the TNMCM rate?
All of the above
What does a low MSE rate indicate about a unit?
That the unit is experiencing turbulence
What is the purpose of a unit's aggressive follow-up program for AWP deferred discrepancies?
To keep visibility on parts ordered for AWP deferred discrepancies
What is the goal of maintenance schedulers regarding AWM deferred discrepancies?
To keep the AWM rate as low as possible
What is a common reason for a CANN action to take place?
When base supply cannot deliver the part when needed
What is included in the CANN rate measurement?
All aircraft-to-aircraft and engine-to-aircraft CANN actions
What is the consequence of not scheduling maintenance with a more extensive maintenance action?
The aircraft will be scheduled down for a day
What is the relationship between the CANN rate and depot support?
The CANN rate is an indicator of depot support
A high Aircraft Availability rate indicates that the maintenance group is unable to provide sufficient aircraft to accomplish mission requirements.
False
The FSE rate measures the percentage of a fleet’s total active inventory that is available for flying.
False
Introducing intentional turbulence to avoid additional turbulence later is a bad management practice.
False
A low FSE rate may indicate that the unit has planned well and executed the schedule.
False
The Aircraft Availability rate is calculated by dividing the total time possessed by the depot possessed time.
False
Sticking to the printed flying schedule reduces personnel tension and allows for a better maintenance product.
True
Definitions of possessed codes can be found in AFI 21-103.
True
NMCM, NMCS, NMCB, and UPNR are types of possessed codes used in calculating Aircraft Availability.
True
A Code 3 break rate is an indicator of aircraft system reliability and maintenance quality.
True
Maintenance scheduling practices can affect the sortie UTE rate.
True
Operations and maintenance share the sortie UTE rate as an indicator of their combined performance.
False
The break rate is an excellent predictor of parts demand.
True
The TNMCM rate is primarily driven by spare parts availability.
False
The TNMCM rate is only used to measure the quality of maintenance performed in a unit.
False
Maintenance should schedule flying first and then support maintenance with the remaining aircraft available.
False
Awaiting Maintenance and Awaiting Parts are two categories of deferred discrepancies that can be resolved during a phase inspection.
True
The CANN rate measures the number of airframes out for parts.
True
A high CANN rate is desirable as it indicates efficient use of resources.
False
A unit can delay resolution of AWP deferred discrepancies indefinitely.
False
The 12-Hour Fix Rate is only applicable to fighter aircraft.
False
Maintenance schedulers can schedule an aircraft down for a week to work deferred discrepancies.
False
Supply relies on maintenance for replenishment.
False
Maintenance missing a scheduled action because an aircraft is pulled to support the flying program is an unreasonable occurrence.
False
Learn about the importance of aircraft availability in maintenance metrics, measuring the ability to provide sufficient aircraft for mission requirements. Understand how to calculate availability and the different codes used. Test your knowledge of flying-related metrics!
