ADS-B Out, are you prepared for the change?
ADS-B OUT (Automatic Dependant Surveillance – Broadcast) requires that the aircraft transmits its own GPS position via the Mode S transponder, regardless of whether the aircraft is being interrogated by a ground radar or by other aircraft’s TCAS. The GPS source must meet high accuracy and integrity requirements only available from a qualified WAAS GPS.
The European airspace mandate for ADS-B Out is effective from June 2020, and from January 2020 for US operations.
Understanding the ADS-B 2020 mandate.
Harry Lees, our principal European avionics consultant has over four decades of experience working across various types, here he explains the basics of ADS-B and why action is required sooner than later in your aircraft maintenance routine.
The European airspace mandate for ADS-B OUT is effective from June 2020, and from January 2020 for US airspace operations.
All aircraft with a MTOW of 5700Kg or above, OR a max cruising TAS of 250kts or above at ISA, must comply (the same requirements as the current EHS Mode S transponder mandate). The US has an extended mandate covering smaller General Aviation aircraft depending on their location.
- Your aircraft will not be permitted into controlled airspace, so no IFR operations.
- Your aircraft is likely to be effectively grounded
- Your airworthiness covenants with a lending bank are likely to have been broken
- Suffer from potential price rises due to supply and demand
- A lack of capacity availability at aircraft maintenance organisations capable of delivering the work
- A shortage of parts from the avionics suppliers. Already we are being advised of 8-10 week delays for parts.
