I have a hypothetical which I'm struggling to understand... hopeing one of the Masters out there can help me out :-)
Let's say we are in a gliding descent at the recommended glide speed of 70Kts on a still day. All of a sudden, we encounter a headwind of 20Kts. Are the following statements correct (?):
1. When the headwind is encountered, assuming there is no change in attitude, the IAS would increase to 90Kts
2. The maximum glide range will still be achieved at 70Kts, because this represents the best lift to drag ratio
3. The attitude of the aircraft should be increased to to get the IAS back to 70Kts to maintain the best glide speed (because the best lift to drag ratio hasn't changed)
4. Even though our ground speed is now 50Kts (20Kts slower than the start) the glide range will remain the same as the start, it will just take longer to get there
Any help would be much appreciated.
