Faculty Advisors may notnot design, build or repair any part of the plane

Mission RequirementsMission Requirements

TakeoffTakeoff- Point when main wheels leave groundPoint when main wheels leave ground

- Regular Class: 200 ft ZoneRegular Class: 200 ft Zone- Open Class: 100 ft ZoneOpen Class: 100 ft Zone

Time LimitTime Limit- Five (5) minutes to complete successful takeoffFive (5) minutes to complete successful takeoff

The aircraft must remain intact during takeoff!!

Competition Circuit Competition Circuit RequirementsRequirements

At least One At least One 360° circuit of the field

- Each aircraft must fly past departure end of field

- Turn aircraft through 180° of heading

- Fly past approach end of takeoff zone prior to landing

Mission RequirementsMission Requirements

LandingLanding

- Touchdown to the point the aircraft stops moving- Regular Class: 400 ft Zone*Regular Class: 400 ft Zone*- Open Class: 200 ft Zone*Open Class: 200 ft Zone*

- Aircraft must remain on the runaway between landing limits to be considered successful landing.

* Rolling-out beyond the landing zone is allowed, provided the aircraft touches-down within the landing zone.

Mission RequirementsMission Requirements

After LandingAfter Landing

- Aircraft must takeoff and land intact to receive points for the flight attempt, with the exception of broken propellers

No Fly ZonesNo Fly Zones- 11stst Violation – Invalid flight attempt (no points) Violation – Invalid flight attempt (no points)- 22ndnd Violation – Disqualification from event Violation – Disqualification from event

Mission RequirementsMission Requirements

Repairs and AlterationsRepairs and Alterations

- Original design of aircraft presented in written and oral reports must be maintained during competition

- Alterations may only be made with the permission of the judges but will result in penalty points

Design ObjectiveDesign Objective

Regular ClassRegular Class

- Design aircraft that can lift as much weight as possible given dual design constraints of power and wing span limits

- Accurately predicting lifting capacity will result in bonus points

- Max aircraft weight of 55 lbs

Design ObjectiveDesign Objective

Regular ClassRegular Class

Flight Score = Raw Weight Score + Prediction Bonus + Empty Payload Bonus

Raw Weight Score = Weight Lifted in pounds × 4

Prediction Bonus = 20 – (predicted payload – actual payload)2

Design ObjectiveDesign Objective

Open ClassOpen Class

- Design aircraft that can lift as much weight as possible given max aircraft weight limit of 55 lbs.

- No wing span limit

Design ObjectiveDesign Objective

Open ClassOpen Class

Flight Score = Raw Weight Score + Prediction Bonus + Zero Payload Bonus + Stopping Bonus (must be in landing zone)

Raw Weight Score = Weight Lifted in pounds x 3

Prediction Bonus = 20 – (predicted payload – actual payload)2

***Open Class aircraft may earn a flat 20-point bonus by performing a flight with zero payload. This bonus will be available during Flight Round 1 only.

Design ObjectiveDesign Objective

Micro ClassMicro Class- The objective of Micro Class is to design

an aircraft that can carry the highest payload fraction possible while simultaneously pursuing the lowest empty weight possible.

- No wing span limit

Design ObjectiveDesign Objective

Micro ClassMicro Class

Flight Score = (10 – EW) x PF x 13

EW = Empty Weight

PF = Payload FractionPW = Payload Weight

PF = PW / (EW + PW)

***No prediction points are available for micro class
