Official Methodology of the “JETVIP Reliability Index”

Nov 29, 2025

What is the JETVIP Reliability Index?

JETVIP Reliability Index is a proprietary system developed by the JETVIP team to evaluate the operational reliability of private aircraft.
The Index helps clients quickly understand how stable, predictable, and dependable a specific aircraft model performs in real-world operations.

This is not a “safety rating.”
All certified aircraft meet strict safety standards.

This is a rating of operational reliability, a crucial factor in business aviation:

  • frequency of AOG events,

  • incident and failure rates,

  • platform maturity,

  • engineering quality,

  • durability of avionics and engines.

All aircraft in our catalog will soon receive their individual JETVIP Reliability Index score.

This becomes the second unique rating system introduced by JETVIP:

  1. the model popularity score,

  2. the model reliability score.

Together, they allow our clients and partners to evaluate aircraft based on the perfect combination of price / reliability / popularity.


How the JETVIP Reliability Index is Calculated

Each aircraft model receives an individual score from 55 to 99, calculated using 24 parameters grouped into six core categories:


1. Platform Reliability (30%)

Based on the reputation and maturity of the aircraft family:

  • stability of engineering solutions

  • accumulated fleet experience

  • manufacturer’s engineering quality

  • known weak points of the model line

Example: Dassault Falcon and Pilatus platforms are traditionally among the most stable.


2. Operational Record & Failure Resistance (20%)

We analyze:

  • MTBF (Mean Time Between Failures)

  • average AOG downtime

  • total fleet flight hours

  • available operational reports

This category reflects how often the aircraft is prone to unplanned ground time.


3. Platform Age & Generation (15%)

Newer generations typically score higher:

  • NG / Gen2 / neo / E2 / NGX versions

  • modern avionics (G5000/G6000, ProLine Fusion, Honeywell Primus)

  • updated engines (PW600, Williams FJ44, GE Passport)

Older versions receive a downward correction.


4. Manufacturer Reputation (15%)

A comprehensive assessment of the brand:

  • consistency of engineering

  • build quality

  • avionics durability

  • long-term operational statistics

Example: Dassault, Gulfstream, Embraer and Pilatus are historically industry leaders.


5. Aircraft Class & Mission Profile (10%)

Different classes naturally have different reliability profiles:

  • long-range jets → highest reliability

  • light jets → medium

  • turboprops → very stable

  • regional aircraft → slightly lower

  • older Soviet/Russian platforms → below average


6. Model-Specific Parameters (10%)

Adjustments based on:

  • specific series (e.g., Learjet 24 vs Learjet 75)

  • engine version

  • known operational quirks

  • aggregated operator feedback


🎯 The Goal of the Rating

To help clients:

  • choose an aircraft that will not let them down,

  • minimize the risk of delays and rescheduling,

  • understand the real operational performance of each model.


🔥 Why the Rating Is Unique

Because it is based on:

  • real operator statistics

  • engineering and maintenance data

  • thousands of accumulated flight hours per platform

  • JETVIP’s own extensive internal database (aircraft, operators, routes)

No similar rating exists anywhere in the CIS region.


📌 Score Interpretation

  • 95–99 → Benchmark reliability

  • 90–94 → Very high

  • 85–89 → Above average

  • 80–84 → Stable and good

  • 75–79 → Average

  • 70–74 → Below average but acceptable

  • 65–69 → Low

  • 55–64 → Weak (older/rare platforms)

Model Reliability

The {{Model Name}} has a reliability rating of {{Rating}} / 100 according to the JETVIP Reliability Index.
This score reflects the aircraft’s operational stability, fleet maturity, manufacturer reputation, avionics generation, and known characteristics of the model.

What this rating means:

  • If Rating ≥ 90:
    This aircraft belongs to the most reliable category in business aviation. The likelihood of unscheduled downtime is minimal.

  • If 85–89:
    A highly stable model with solid engineering and predictable performance.

  • If 80–84:
    A reliable and well-balanced aircraft suitable for regular charter operations.

  • If 75–79:
    A moderate reliability level. Suitable when balancing cost and mission profile.

  • If 70–74:
    A working platform that may be older or simpler. Occasional AOG events are possible.

  • If <70:
    A less reliable platform by modern standards. We recommend checking the condition of the specific aircraft before booking.

What influences the score:

  • structural and engineering stability

  • aircraft age and avionics generation

  • engine reliability

  • manufacturer reputation

  • operational failure statistics

This rating helps clients choose an aircraft that will provide a comfortable, predictable, and disruption-free flight experience.
