Possible disadvantages

• Cost

• Security Concerns
  Uploading sensitive documents to an external server for conversion could pose potential privacy and security risks.
• Limited Offline Functionality
  Users cannot convert documents offline, which restricts the service for users needing offline capabilities.

Possible disadvantages

• Coverage Limitations
  Despite extensive data collection, OpenSky Network may have gaps in data coverage, especially in areas with fewer contributors or less air traffic.
• Data Latency
  Due to the nature of its crowd-sourced data collection, there can be delays in data updates depending on the contributors’ setups and connectivity.
