"FAA PTS limits are 3/4 scale deflection and +/- 10kts"
  • FAA = Federal Aviation Administration -> the US aviation authorities
  • PTS = Practical Test Standards -> examination rules for passing official tests
  • 3/4 scale deflection = out of dots -> three out of four dots off on a VOR/LOC/GS annunciator, actual degrees depending on High or Low sensitivity
  • +/- 10kts = speed -> usually the proposed speed, also valid for IAS on configured ILS, so if 450fpm@90kts needed never less 80, never above 100
