An emergency situation is one in which the safety of the aircraft or of persons on board or on the ground is endangered for any reason
Types of emergencies
Fire on board the aircraft
Technical defects and instrument malfunction (engine failure, loss of pressurization, issues that can endanger the lives of people on board.
Shortage of fuel
Extreme bad weather
Sickness of a passenger or crew needing medical attention
Aircraft damage e,g bird strike
Illegal activity (bomb threat, hijacking)
It is an emergency procedure word used internationally as a distress voice radio communication.
Mayday procedure word originated in 1923, word derived from a French word meaning come and help.
All operators provide a manual of emergency procedures both to ground staff as well as flying staff.
Emergency briefing and training is mandatory and all staff are required to attend these sessions once a year, training records are subjected to audit checks.
Safety and emergency procedure training (SEPT)
The objective of the Safety and Emergency Procedure Training (SEPT) courses is to ensure crew are equipped with the necessary skills to handle any emergency or unusual situation that can occur on-board their aircraft and that they are informed of any new regulations, procedures or equipment.
In terms of CAA legislation, both flight deck and cabin crew are required to undergo SEPT recurrence training annually. Crews are also required to complete a skills test on board the aircraft on which they operate. Should they operate on more than one aircraft type, a skills test will need to be completed for each aircraft type
An emergency landing is a prioritized landing made by an aircraft in response to an emergency which contains an imminent or on-going threat to the safety and operation of the aircraft or involves a sudden need for a passenger or crew for necessary treatment for a medical emergency.

Example of an emergency landing
Navajo Save (quote from records)
On a late afternoon in June 1993, air taxi pilot Edward Wyer, a 45-year-old ex-RAF Tornado pilot, took off from Birmingham, England, on a flight to Norwich, about 130 miles due east. Aboard were seven passengers—a load that, in his eight-seat Piper Navajo, made even a low-rent charter airliner seem spacious. The two back-row fares sat with their knees in their faces, and Wyer had a traveler next to him in what normally would have been the copilot’s seat.
Some 40 miles west of Norwich, as Wyer slowly reduced power to begin his descent, there was a huge bang, the airplane shook like a soggy Labrador and both engines went silent.
The right engine, in fact, went away—tore itself from its mounts and fell off. It had shed one of its three prop blades, and the huge rotating imbalance ripped the engine loose. Nor was that the only damage done by the big aluminum blade. Flung with incredible force through the Navajo’s nose, it flew out the other side and into the left engine’s prop, killing that engine.
Meanwhile, the sudden asymmetry had snapped the Piper into a tight spin to the right, which Wyer managed to correct after only two turns—nice work even if you’re fully prepared for a practice spin in an intact airplane. Wyer tried his best to reach a satisfactory glide angle, but
Coming down fast, Wyer spotted an open field to his left and without hesitation turned toward it, even though the approach path was complicated by powerlines.It took two hands on the yoke and all his strength to manage the airplane, so there was no way Wyer could hand-pump the flaps and landing gear down with the emergency handle, but he managed to get over the wires and put the Navajo down on its belly so gently that the sole injury was to a passenger who later claimed whiplash.
Accident investigators were able to verify the exact place where the Navajo’s tail had first brushed a tall stand of crops, and the neatly cut swath showed that the airplane had sunk inch by inch over a 2,300-foot flare and slid a smooth 460 feet after ground contact
