AWOS: Automated weather observing system. A suite of weather sensors of many different configurations either procured by the FAA or purchased by individuals, groups or airports that are required to meet FAA standards. AWSS — automatic weather sensor system — is functionally the same as ASOS. A state or airport can purchase an AWOS with […]

Relevant Discussion: FAR part 107, AC 107-2 Operating Requirements: Avoid manned aircraft, and never operate in a careless or reckless manner. The drone must remain within sight. Alternatively, if you use first-person view or similar technology, you must have a visual observer always keep your aircraft within unaided sight (for example, no binoculars are allowed). […]

1. Satcom Satellite communication system — Aeronautical mobile satellite service developed as a primary communications link for remote areas and oceanic airspace. Satcom supports voice and data transmissions but is sometimes prone to long transfer delays. 2. ACARS Airborne communications addressing and reporting system — Air/ground datalink is the standard for ACARS, which has been […]

(Read part one here.) VLOF — Liftoff speed. Speed at which the aircraft becomes airborne. Back pressure is applied at VR (rotate) — a somewhat lower speed — so that liftoff actually happens at VLOF. VMCA or VMC — More commonly known as VMC (although VMCA is more correct). Minimum control speed with the critical […]
