Federal Aviation Administration, DOT Pt. 135, App. F The recorded values must meet the designated range, resolution and accuracy requirements during static and dynamic conditions. Dynamic condition means the parameter is experiencing change at the maximum rate attainable, including the maximum rate of reversal. All data recorded must be correlated in time to within one second. Accuracy (sensor input) Seconds per sampling interval Section2Section Unless Higher Accuracy Uniquely Required.

Remarks Discretes should show which systems are engaged and which primary modes are controlling the flight path and speed of the aircraft. For autoland/category 3 operations. Each radio altimeter should be recorded, but arranged so that at least one is recorded each second. For autoland/category 3 operations. Each system should be recorded but arranged so that at least one is recorded each second. It is not necessary to record ILS and MLS at the same time, only the approach aid in use need be recorded. For autoland/category 3 operations. Each system should be recorded but arranged so that at least one is recorded each second. It is not necessary to record ILS and MLS at the same time, only the approach aid in use need be recorded. A single discrete is acceptable for all markers. Record the master warning and record each - red - warning that cannot be determined from other parameters or from the cockpit voice recorder. If left and right sensors are available, each may be recorded at 4 or 1 second intervals, as appropriate, so as to give a data point at 2 seconds or 0.5 second, as required. A suitable combination of discretes unless recorder capacity is limited in which case a single discrete for all modes is acceptable. 531 VerDate Sep<11>2014 08:20 May 17, 2019 Jkt 247048 PO 00000 Frm 00541 Fmt 8010 Sfmt 8002 Y:\SGML\247048.XXX 247048
