Here are the background facts:
This excercise has the objective to familiarise the student with the slow flight characteristics.
The steps are:
1)Establish straight and level, 90% RPM, 15 units AoA, hands out trimmed. (No specific airspeed, it just happens to be appr. 110 KIAS)
2) Add 5% RPM (so i set it at 95%) and establish a climb with 15 units AoA for 500 ft climb. No bank, whatsoever. (Again no specific airspeed, it just happens to be appr. 100-105 KIAS)
3) Reduce 5% RPM so you fly straight and level at the new altitude (Same parameters as step 1)
4) Reduce 5 % RPM (so i set it at 85%) and establish a dive with 15 units AoA for return to the initial altitude. No bank whatsoever. (No specific aispeed during the dive, it just happens to be appr. 115-120 KIAS).
My question is simple. Why is the airspeed different? The answer might be simple. I simply can't figure it out. Hope i clarified it as much as possible.
