Describe the actions that should be taken, time, height and other factors permitting, during a forced landing: Stress that pilots should be aware of wind velocities at all times. It is always preferable to be into-wind on a forced approach, but a suitable landing area is the prime consideration. In other words, it is better to land down-wind in an open field when the only alternative is to land in tall trees with the wind on the nose. Remind the student that turns and speeds above or below the manufacturer’s recommended speed in autorotation increase the rate of descent substantially. Discuss the problem associated with ditching a helicopter. Discuss the techniques of forced landing into trees, mountainous terrain and built-up areas. Point out that an engine failure when flying at low level over obstacles will result in a forced landing that is difficult to successfully accomplish without damage and injury. For this reason, pilots should always fly as high as the task and common sense allow. AIR EXERCISE Demonstrate forced approaches from a height that will allow the full procedure to be carried out without haste. Student practice Demonstrate practice forced landings of increasing difficulty from different altitudes. Student practice TIPS FOR INSTRUCTORS This is not a procedure that can be allotted a certain time period for the course and left at that. After students are competent they should be given surprise practise engine failures without sufficiently warning them on as many dual trips as possible. This enables students to practise the procedure regularly and will develop the judgement skills necessary to consistently make the selected area. 19 QUICK STOPS PREPARATORY INSTRUCTION Aim For the student to learn how to come to the hover into wind from various speeds, at a constant altitude Review Airspeed and Power Changes: Exercise 4 Motivation |
