10.1 Number of Flights
Time and weather permitting, each contestant shall be given an opportunity to make no more than two official flights in each competition event unless otherwise specified in the rules for a specific event. This limitation shall not apply at Record Trials. Unless otherwise specified in the rules for a specific event, a contestant in a duration event shall receive as his/her official score, the sum of the durations achieved by the contestant on all official flights.
It is suggested that the Contest Director carefully consider constraints imposed by the time and weather when deciding on the number of flights that is to be allowed each contestant in an event, since in many events a contestant who cannot make both flights will be at a severe disadvantage. In such cases, it is preferable to limit contestants to one flight in one or more events than to impose a hardship on contestants who could not make both flights due to lack of time or inclement weather. If such a limitation is necessary, it should be announced prior to any official flight by any contestant in the event being so limited. In circumstances where it is necessary to enact such a limitation after official flights have been made in an event, i.e., a sudden weather change, all contestants, regardless of how many official flights they have already made shall be bound by the new limits. In these circumstances, the Contest Director shall select for consideration only those flights of a contestant that would be qualified under the new limitation, and shall then choose the best of the selected flights as the official flight of that contestant in that event.
For example, if the Parachute Duration event must unexpectedly be limited to one flight per contestant, and a contestant has already made two flights, the Contest Director must first select only the flights that were returned, (since in single-flight Parachute Duration, the flight must be returned). If both flights were returned, the Contest Director shall select the better of the two flights as the official flight of the contestant.
10.2 Record Attempts
At the discretion of the Contest Director, any NAR member or Team may be allowed to attempt to set or surpass a United States Model Rocket Performance Record in any class of any event allowed in Rule 17.2, whether or not the event is listed on the sanction application for the meet. (See Rule 6.3.6.)
10.3 Official Flight Requirements
A flight is official if any part of the model leaves the launcher under a motor’s thrust phase; except in the case of a catastrophic failure according to the provisions of Rule 11.5, in which case the flight is not considered to be official. All models that do not leave the launcher subsequent to motor ignition shall not be considered as having made an official flight unless they are disqualified by the RSO for safety reasons. If the power pod or motor of a Boost Glider model disengages and proceeds into the air under power without the glider portion, the attempt shall be considered a disqualified official flight. A model that does not ignite enough motors to be in the proper total impulse class as per Rule 4.6 shall not be considered as having made an official flight unless its flight is disqualified for other reasons.
10.4 Return of Inaccessible Models
When the return of a model is required, and the contestant cannot return his/her model, but can point out (to a qualified official) the model, visible in an inaccessible place such as a tree, power line, lake, or rooftop where recovery would pose a personal hazard to the contestant, the Contest Jury has the option of scoring the model as having been returned. The Range Safety Officer, the Contest Director, members of the Contest Jury, or Timers or Trackers assigned to follow the contestant’s model are qualified officials for the purposes of this rule. The Contest Director shall state prior to the start of competition what distance limits such officials may travel to act as observers under this rule. This rule may be superseded by the rules of a specific event.
10.5 Recording of Returns
It is the responsibility of the contestant to ensure that the officials have noted on the entry card that the model has been returned, where it is so required.
