XPRS Loft Duration / Extreme Altitude Contest Guidelines 

Note: Any flight made during the week of ARLISS / XPRS is qualified to enter.

Extreme Altitude:

Focused on motor classes H through O as well as a Two-Stage category

(any flight comprised of HP rocket motors in the booster and sustainer).

Note:  All rockets and / or motors meeting TRA safety requirements, including experimental motors and / or rockets are encouraged to participate.

• Clustered rockets will be considered based on total impulse of all motors.
• Flyers must be TRA or NAR certified for motor class they are entering. 
• TMP or NAR Jr Level 1 flyers must meet all the requirements of those programs with awards presented to the under 18 yr old participant.

Objective: 

To fly as high as possible with a successful recovery (including recovering within the FAA Waiver in effect at the time of the flight).  

• For all flights (including the booster and sustainer on two-stage flights) any damage must be limited to the same criteria as a TRA certification flight. 
• Non-deployment of recovery mechanism disqualifies a flight including the booster on two-stage flights.

Flight Data requirements:  

1. The highest recorded altitude from a “brand name” altimeter or flight computer must be entered on flight contest form and submitted in the contest box prior to 4pm on Saturday.
2. Note: Contest Coordinator(s) may ask to review altimeter / flight computer data if obvious questions arise, e.g. a clear data “outlier” or suspect data recorded by device.  For example, a K to K two stage flight that has a recorded altitude of 100k ft.
3. Otherwise, data submitted by each flyer is accepted on the honor system.

Awards: For each motor class certificates are given for 1st, 2nd and 3rd place

with a trophy awarded to the first place contestant.

Loft duration:

Is focused on flyers 17 yrs and younger and

encompasses motor classes A through G

Objective: 

To keep a rocket in the air as long as possible.  

• Flights are timed from launch to touchdown.  
• Rocket must be presented to LCO or RSO after each flight for inspection. 
• To qualify, the rocket must be in a re-flyable condition or returned to that status with minor field repairs.  
• Detached fins or non-deployment of recovery mechanism disqualifies a flight (unless rocket is designed as a “tumble recovery”).
• Contestant must present contest form to LSO or RSO prior to each flight.
• LSO or RSO must note the “loft duration” time on contest form and participant (or responsible parent) must insure that the contest form is filled out and returned to contest box prior to 4 p.m. Saturday.
• Clusters or staged rockets will be considered based on total impulse of all motors.

Note: LSO and / or RSO cooperation for timing and inspection will be required. 

Awards: For each motor class, certificates are given for 1st, 2nd and 3rd place with a trophy awarded to the first place contestant.

Decisions by contest Coordinator are final but appealable.
