Fleet

Fleets are groups of aircraft that share common characteristics. A fleet defines capacities, route restrictions, SimBrief configuration, and default images that all aircraft in the fleet inherit. Individual aircraft can override these defaults when needed.

Accessing Fleet Management

In Orwell, go to Fleet → Fleet. You need the Manage Aircraft permission.

Fleet Structure

Your fleet structure can be as simple or complex as your VA needs. Most airlines start simple:

• B737

• A320

But you can split fleets by region or operation type:

• B738 - UK

• B738 - EU

Or even more granular:

• B738 - UK Charter

• B738 - UK Scheduled

• B738 - EU Charter

• B738 - EU Scheduled

Split fleets become powerful when combined with Allowed Prefixes to control which aircraft operate which routes.

Fleet Settings

General Tab

Field	Description
Name	Display name for the fleet (e.g., "B737-800 UK Ops")
Type Code	ICAO type designator (e.g., "B738"). Must be a real code supported by SimBrief.
Fleet Type	Determines capacity fields and cargo handling (see Fleet Types below)
Maximum Passengers	Number of passenger seats. Aircraft inherit this unless overridden.
Maximum Cargo	Cargo capacity in kg (commercial freight, not baggage). Aircraft inherit this unless overridden.
Maximum Containers	Container unit count. Aircraft inherit this unless overridden.
Allowed Prefixes	Which callsign prefixes this fleet can operate. Empty means all routes.
Hide in Phoenix	Hides this fleet from Phoenix → Resources → Aircraft
PIREP Scoring Group	Groups this fleet for PIREP scoring comparisons

Fleet Types

Type	Required Fields	Use Case
Passenger	Max Passengers	Pure passenger operations with no commercial freight
Passenger & Freight	Max Passengers, Max Cargo	Mixed passenger and cargo by weight
Passenger & Containers	Max Passengers, Max Cargo, Container Units	Passengers with containerised cargo
Cargo - Freight	Max Cargo	Dedicated freighter by weight
Cargo - Containers	Container Units	Dedicated freighter by container count

Allowed Prefixes

Allowed Prefixes control which routes a fleet can operate. Routes have callsign prefixes (like "BAW" or "SHT") configured in Settings → Callsign Parameters.

• Empty: Fleet can operate all routes

• With prefixes: Fleet only appears for routes matching those prefixes

When you remove a prefix from a fleet, routes using that prefix are automatically deallocated from the fleet.

SimBrief Integration Tab

Configure SimBrief defaults for all aircraft in this fleet. Individual aircraft can override these settings.

Enforced SimBrief Aircraft Profiles (Fleet-only) - Specify which SimBrief profiles pilots can choose when booking. This restricts pilot selection to approved profiles.

Other SimBrief overrides include:

• OFP Layout - Force a specific OFP format

• Airframe Equipment - Performance code, weight category, ETOPS settings, ICAO equipment

• Airframe Weights - Passenger/baggage weights, OEW, MZFW, MTOW, MLW, max fuel

• Fuel Planning - Contingency, reserve, minimum fuel values

• Performance - Fuel factor, climb/cruise/descent profiles

• Alternate Management - Override how SimBrief searches for alternates

ACARS Sounds Tab

Upload custom sounds for Pegasus to play during flights with this fleet. You can customise sounds for: boarding, pushback, safety briefing, climb, cruise, descent, approach, landing, and unloading.

Image Tab

Upload a default image for this fleet. Images are displayed in:

• Pegasus during flight

• Live Flight map when viewing flight details

• Phoenix aircraft resource pages

• Orwell fleet management

If no fleet image is set, vAMSYS falls back to Planespotters images when available. Individual aircraft images override the fleet default.

Recommended size: 400x300 pixels, highly optimised.

Inheritance

Fleets provide defaults that aircraft inherit:

Setting	Inheritance Behaviour
Capacities	Aircraft uses fleet value unless aircraft has its own override
SimBrief settings	Aircraft overrides take priority, then fleet, then airline defaults
Image	Aircraft image → Fleet image → Planespotters

Tips

• Start simple - Begin with basic fleets (B737, A320) and split later if needed

• Split fleets for route control - Multiple fleets with the same type code but different Allowed Prefixes lets you control which aircraft serve which routes

• Fleet filter setting - If using split fleets, check Settings → Booking & Dispatch → Flight Centre use Fleet Filters to control whether filtering uses fleet name or type code

• Pair profiles with overrides - Use Enforced SimBrief Profiles for weight handling, then add fuel planning overrides separately

• Scoring groups - Use PIREP Scoring Groups for fair scoring comparisons (e.g., separate turboprop and jet categories)
