On 5 April 2019 CASA made the Part 101 (Unmanned Aircraft and Rockets) Manual of Standards 2019 (MOS) which contained in chapter 5 the requirements for RPA operations Beyond Visual Line Of Sight (BVLOS). Class 1 operations no longer require the dreaded IREX (Instrument Rating Exam). For operations using class 2 EVLOS, an IREX is required. First, let’s understand what CASA means by EVLOS.
EVLOS is where the RPA is flown beyond the pilot’s visual line of sight but at least one visual observer is VLOS with the RPA or knows the exact location of the RPA. Essentially, the observer must be able to clear the air and ground environment around the RPA so careful selection of the observer’s location is critical in the planning of any EVLOS operation. Unlike VLOS requirements (CASR101.073(3)) the observer can use devices such as binoculars to observe the operating area but must not use these devices as the primary means of keeping the surrounding airspace and ground insight. CASA has divided EVLOS operations into 2 classes:
If EVLOS operations might be applicable to your operation, what does MOS101 require ReOC holders to provide to get an approval? Firstly, don’t just copy the MOS 101 chapter 5 into your manuals and think this will satisfy CASA. Read MOS 101 chapter 5 and the explanatory statements, search the CASA website or contact CASA for the latest information /advice on what they require from an EVLOS application. JARUS have also released a standard scenario for BVLOS operations in uncontrolled airspace which is well worth reading if you intend to do Class 2 EVLOS operations. MOS 101 directs you to develop practices and procedures for EVLOS operations so decide on your concept of operations (CONOPS), some essential questions are:
Visual Observer EVLOS
Once you have developed a CONOPS work through each section of the MOS developing detailed procedures and training requirements; you may feel like you are spending a lot of time here but it will all pay off when the unforeseen happens during an EVLOS operation. Once you have developed your procedures go and try them out under VLOS conditions, at a quiet location to see that they all work as envisaged. Once everything is documented you can submit your manuals to CASA. CASA may require you to demonstrate your EVLOS procedures, particularly, if you are requesting approval for Class 2 operations so you need to be prepared for this.
