Maintenance Aircraft

When to use this

Add a new aircraft when expanding your fleet or transferring an aircraft into your maintenance programme. This creates the aircraft record that will be used for maintenance tracking, schedule compliance, and component assignment.

Steps

1. Click "Add Aircraft" in the top-right corner of the Maintenance Aircraft tab
2. Complete the Aircraft details section:
   • Aircraft Registration: Enter the registration (required, max 10 characters)
   • Serial number: Enter the manufacturer's serial number (optional)
   • Operator: Select the operator from the search field (required)
   • Date manufactured: Select the manufacturing date
   • ICAO Type Designator: Choose the aircraft type (required)
   • Aircraft model: Select the specific model variant if applicable
   • Nationality: Select the aircraft's country of registration
   • Passenger Seating Capacity: Enter the number of passenger seats (required)
   • Has Lavatory on Board: Check if applicable
   • Weight unit of measure: Select kg, lbs, or tonnes (required)
   • Maximum Take-off Weight: Enter MTOW in the selected unit
   • Schedule display colour: Choose a colour for calendar views
3. Configure Engine positions: Check which engine positions apply to this aircraft (e.g., Position 1, Position 2)
4. Set Feature flags:
   • Enabled for Flight Operations: Check to make aircraft available for flight scheduling
   • Enabled for Documents: Check to enable document management for this aircraft
5. Click "Submit": Save the new aircraft

Result

The new aircraft appears in the Active aircraft table. If engine positions were configured, empty slots appear in the corresponding columns. The aircraft is immediately available for engine assignments, maintenance action creation, and (if enabled) flight operations.

Notes & rules

• Registration must be unique: You cannot create two aircraft with the same registration
• Required fields are marked with an asterisk: Registration, Operator, Type Designator, Passenger Seating Capacity, and Weight unit
• Engine positions depend on aircraft type: The available engine positions reflect the selected aircraft type's configuration
• Feature flags control visibility: If "Enabled for Flight Operations" is unchecked, the aircraft won't appear in flight scheduling modules

When to use this

Edit an aircraft to update its configuration, change operators, modify seating capacity, or adjust feature flags. All fields can be modified except the unique aircraft ID.

Steps

1. Locate the aircraft: Use search or scroll through the Active aircraft table
2. Click the blue Edit button (pencil icon) in the Edit column
3. Update any fields as needed in the aircraft window
4. Click "Submit": Save your changes

Result

Changes are saved immediately. The table refreshes to show updated values. If you changed the aircraft type or engine positions, the engine slot columns update accordingly.

Notes & rules

• Changing aircraft type affects engine positions: If you change the aircraft type, verify that the current engine assignments are still compatible
• Disabling Flight Operations flag hides the aircraft: Unchecking "Enabled for Flight Operations" removes the aircraft from flight scheduling views

When to use this

Assign an engine when installing a new or existing engine into an aircraft engine position. You can either create a new engine record or move an existing engine from stores or another aircraft.

Steps to create and assign a new engine

1. Locate the aircraft and engine position in the Active aircraft table
2. Click the "+ Engine" dropdown button in the appropriate engine position column
3. Select "Create new engine"
4. Complete the Engine Assignment window:
   • Serial number: Enter the engine serial number (required)
   • Engine model: Select from the dropdown or create a new engine model
   • Aircraft: Pre-filled with the selected aircraft
   • Engine position: Pre-filled with the selected position
   • Date fitted: Select when the engine was installed
   • Total time on engine: Enter the current engine hours
   • Cycles on engine: Enter the current cycle count
5. Click "Submit": Save the engine assignment

Steps to assign an existing engine

1. Click the "+ Engine" dropdown button in the appropriate engine position column
2. Select "Add existing engine"
3. In the Move Engine window:
   • Select the engine: Choose from engines currently in stores
   • Date fitted: Select the installation date
4. Click "Submit": Move the engine to the aircraft

Result

The engine appears in the engine position column as a green button showing the serial number. The engine is now tracked for maintenance actions and time/cycle counts. If the engine type requires a propeller, a "+ Propeller" button appears below the engine.

Notes & rules

• Engine serial numbers must be unique: You cannot create duplicate engine serial numbers
• Engine model compatibility: Ensure the selected engine model is compatible with the aircraft type
• Moving engines closes previous assignments: When you move an engine from another aircraft, the previous assignment is automatically closed with a removal date

When to use this

Move an engine when performing an engine change, sending an engine for overhaul, or rotating engines within the fleet. Engines can be moved to stores (off-wing) or directly to another aircraft position.

Steps

1. Locate the engine in the Active aircraft table (shown as a green button with serial number)
2. Click the engine serial number button to open the dropdown menu
3. Select either:
   • "Move to stores": Remove the engine from the aircraft (off-wing)
   • "Move to another aircraft": Transfer the engine to a different aircraft
4. In the Move Engine window:
   • For stores: Select the removal date
   • For another aircraft: Select destination aircraft, engine position, and fitment date
5. Click "Submit": Complete the move

Result

The engine disappears from the original position. If moved to stores, it becomes available in the "Add existing engine" list. If moved to another aircraft, it appears immediately in the destination position. The previous assignment is closed with a removal date, and a new assignment is created.

Notes & rules

• Propellers move with engines: If a propeller is fitted to the engine, it remains attached during the move
• Time and cycles are preserved: Engine hours and cycles continue accumulating after the move
• Removal date cannot be before fitment date: The system validates date logic

When to use this

Assign a propeller when installing a new or existing propeller onto an engine. Only engines configured with the "Has Propeller" flag show propeller assignment options.

Steps to create and assign a new propeller

1. Locate the engine in the Active aircraft table
2. Below the engine button, click the "+ Propeller" dropdown
3. Select "Create new propeller"
4. Complete the Propeller Assignment window:
   • Serial number: Enter the propeller serial number (required)
   • Propeller model: Select from the dropdown or create a new propeller model
   • Engine: Pre-filled with the selected engine
   • Date fitted: Select when the propeller was installed
   • Total time on propeller: Enter the current propeller hours
   • Cycles on propeller: Enter the current cycle count
5. Click "Submit": Save the propeller assignment

Steps to assign an existing propeller

1. Click the "+ Propeller" dropdown
2. Select "Add existing propeller"
3. In the Move Propeller window:
   • Select the propeller: Choose from propellers currently in stores
   • Date fitted: Select the installation date
4. Click "Submit": Move the propeller to the engine

Result

The propeller appears below the engine as a green button showing the serial number. The propeller is now tracked for maintenance actions and time/cycle counts.

Notes & rules

• Propeller serial numbers must be unique: You cannot create duplicate propeller serial numbers
• Propeller model compatibility: Ensure the selected propeller model is compatible with the engine model

When to use this

Deactivate an aircraft when removing it from the active fleet, selling it, or placing it in long-term storage. Deactivation is a soft delete that preserves all historical data.

Steps

1. Locate the aircraft in the Active aircraft table
2. Click the red Deactivate button (ban icon) in the Deactivate column
3. Confirm the action in the confirmation window

Result

The aircraft is removed from the Active view and appears in the Deactivated view. All maintenance history, engine assignments, and documents are preserved. The deactivation date and time (UTC) are recorded.

Notes & rules

• Engines and propellers are not automatically deactivated: Components remain active and must be moved to stores or deactivated separately
• Deactivated aircraft cannot be used in Flight Operations: They are hidden from flight scheduling even if the feature flag is enabled
• You can reactivate aircraft: Switch to the Deactivated view and click the green Activate button

When to use this
