During the approach to land, an aircraft encounters wind shear with a decreasing headwind. If the pilot makes no correcting action, the aircraft will experience a:
1. Rate of descent decrease
2. Rate of descent increase
3. Increasing airspeed
4. Decreasing airspeed
It is perhaps better to consider these questions in terms of the aircraft's energy:
- Headwind increasing / tailwind decreasing = gain of energy
- Tailwind increasing / headwind decreasing = loss of energy
In this question it states: 'an aircraft encounters wind shear with a decreasing headwind'. This will result in a loss of energy and so:
- Rate of descent increases
- Aircraft sinks below the approach / glide slope
- Airspeed decreases
- Increased risk of stall
