Flight Planning and Dispatch

Seek Improved Efficiency

The aviation industry has relied on SkedFlex MISA for more than two decades to manage its business operations effectively with our proven, stable, and user-friendly tools.


Maintenance combines maintenance planning, forecasting, and tracking into one powerful form to keep your maintenance personnel doing what they do best: working on aircraft, while allowing maintenance management the ability to track cost, revenue, and easily create detailed invoices for maintenance work performed.


Accounting is integrated throughout MISA, allowing detailed accounting information to feed balance sheets, income statements, and trial balance reports. For companies that have their own accounting system, MISA can collect accounting data and pass it to other systems.

Inventory Management

Inventory management tracks every part, every time. From purchase or repair to receipt, installation, removal, overhaul, or swap. Each movement creates detailed accounting audit trails for inventory control, compliance, and valuation.


Purchasing is all-inclusive, making it easy to manage repairs, purchases, warranties, and vendor performance.

Human Resources

Human Resources tracks employee information, collects labor for any number of pay codes (and against multiple work orders) while creating an exportable payroll file for integration with any payroll service.


As an integrated solution, MISA leverages a holistic approach to create payroll weeks and payroll periods. MISA is flexible enough for special payrolls, adjustments, government program customers, and any payroll that may include special pay such as COLA, HOLA, Hazardous Duty Pay, etc.

Labor Tracking

An extensive labor tracking module that tracks individual work hours, cost collection, and customer billing, as well as employee scheduling, PTO management, and labor records needed for payroll and labor evaluation and planning.

Flight Operations

As a stand-alone product, MISA offers a ‘light’ version of the SkedFlex flight operations solution. This includes creating weekly flight schedules, pilot and aircraft assignments, dispatcher recordings of flight details, and data-tracking necessary to forecast and plan for aircraft maintenance.


It is a common practice for aviation companies to use multiple applications to manage their operations; whether custom-built, acquired from a third-party, part of a legacy system, or a combination thereof. Often, such applications have limited interfaces necessitating duplicate data entry – a recipe for inducing errors and decreasing efficiency. Even when interfaces exist, they can be difficult to manage and require resources to build, maintain, and support them.

MISA provides the solution for these issues by standardizing, streamlining, and integrating business processes across all the various departments and functional areas within the company; and this integration improves the bottom line while providing employees a user-friendly and consistent application experience across the whole organization.
