Stick the power up which is becuase your below profile the airspeed will stay the same.....
I don't think that a single student would understand that statement. I am not trying to fly the aircraft at the moment and after reading it 10 times I still can't make it out.
Could it be that the aircraft is below profile in the question asked because of the "sink"? and perhaps it was 100% on profile and speed until that point so the power and the trajectory must have been correct. So increasing the power at 5ft above the tree tops will fix it?

Lets pause 12/13 for a minute and go back to 6.
We are flying straight an level in trim at 100Kt.
maintain straight and level flight while slowing to 80Kt.
Hands up those that will straight away pitch up to slow down?
maintain straight and level flight while increasing speed to 120Kt
Hands up those that will pitch down to speed up?
I hope that no instructor has their hand up.
Straight and level at different speeds-
Accelerate;
1. Increase power
2.
Prevent yaw, pitch and roll
3. as aircraft accelerates adjust attitude to maintain constant altitude
4 at desired speed set power and trim
Decelerate;
1. Reduce power
2.
Prevent yaw, pitch and roll
3. as aircraft decelerates adjust attitude to maintain constant altitude
4 at desired speed set power and trim
Simple.
That exercise should not change just because the trajectory is something other than horizontal.
Next deviations;
Aircraft is established straight and level at 100Kt, 2000ft in trim
Instructor "makes" aircraft 100ft low and askes student to regain 2000ft.
Student
simultaneously pitches up slightly to cause a climbing trajectory and increases power slightly to prevent speed loss. Aircraft is re-established at 2000ft in trim straight an level.
Instructor "makes" aircraftv 100ft high and asks student to regain 2000ft
Student
simultaneously pitches down to cause a descending trajectory and decreases power slightly to revent speed increase. Aircraft is re-established at 2000ft in trim straight and level.
All very easy.
