    Hot surfaces are an integral part of the technological processes of agricultural crop processing. Hot surfaces' temperature, at critical points, may exceed their minimum ignition temperature. The article aims to experimentally monitor the behaviour of hay in the event of its exposure to radiant heat. The mentioned model is implemented using a hot-plate device. The hot plate has a defined temperature-time curve. Based on the temperature-time curve, the hot surface´s temperature is determined as the minimum ignition temperature of the examined hay sample. At the same time, the temperatures inside the tested material were monitored. The heterogeneity of these samples significantly affected the nature of thermal degradation of biomass samples. The hay ignition temperature (406 ° C) can serve as a tool to assess the risk of fire.

    The paper is focused on the precautionary landing, its procedures and decisions that affect the pilot during the flight and landing itself. The main purpose of the work is a detailed analysis of procedures, circumstances supporting the aforementioned decision, as well as safety landing training and the scope of exercises of this role in pilot training. The work describes in detail the methodology for precautionary landing, simulation of precautionary landing and analysis of the most ideal area for landing. Furthermore, the work mentions the legislation that affects flight training, as well as legislation governing in-flight emergency procedures. Last but not least, the possibilities of precautionary landing training and the most ideal procedures in an emergency situation are also described within. Theoretical knowledge was achieved by studying available materials and practice. The conclusion of the training of precautionary landing is to train the excercise in other training tasks than prescribed for precautionary and emergency landing. The result is a summary of information and practical advice for the correct execution of the landing with the least possible risk of injury to the flight crew and damage to property.
