Steep Spiral Flashcards
Purpose and relation to emergency landing
- develop division of attention, coordination, and energy management while dealing with changing altitudes, pitch, and bank while maintaining a constant distance around a point
- also has a practical application, able to lose altitude while staying over a selected point for landing in an emergency situation
Selection of an entry altitude
- manuever should be completed prior to reach 1500 AGL
- triple approximate altitude lost per turn and add 1500 ft to find entry altitude
Entry airspeed and power setting
- airspeed = cruise, around 105 knots, want to maintain around 85 knots during manuever
- power setting = power comes to idle just before beginning maneuver
- enter on the downwind
Selection of a proper ground reference point
- prominent visual landmark
- intersection is good idea
Division of attention and planning
- majority should be spent looking outside
- look inside to check airspeed, coordination, bank angle, etc
Coordination of flight controls
- important to maintain coordination throughout the entire maneuver bc we are at a reduced power setting, so uncoordinated flight leads to decreased performance and mushy controls
Maintenance of constant radius
- just like turns around a point
- higher GS = higher bank
Maintenance of constant airspeed
- pitch for airspeed
- trim can help hold pitch
CE, Improper pitch, bank, yaw, and power coordination during entry or completion
- initital bank will be steepest due to highest GS
- we take power out at beginning or maneuver = add power back at the end of manuever
CE, uncoordinated use of flight controls
- not maintaing coordinations leads to decreased performance as well as mushy controls
CE, Improper planning and lack of maintenance of constant airspeed and radius
- not choosing correct entry altitude
- higher GS = higher bank, changing GS throughout maneuver = changing bank
CE, Failure to stay orientated to the number of turns and the rollout heading.
- maintaing SA by choosing prominent visual landmark as well as noting Heading indicator in airplane, roads make this easy
