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.
