Go/No-Go point
Turbine engines require approximately ____ seconds to produce full power from flat pitch.
5 seconds
CAUTION: Caution is to be exercised for slopes greater than ___ degrees, since rigging, loading, and wind conditions may result in flight controls contacting the control stops

What type of approach has advantages/disadvantages such as:
Advantages: the ability to view RT and touchdown point from the beginning of approach and more time (altitude) to respond to changes/emergencies?
Disadvantages: More power required
Steep Approach
