UKRA amendment to certification flight rules.

________________________

Certification flights:

With immediate effect the United Kingdom Rocketry Association are amending the rules relating to certification flights.

The amendment is as follows: _________________________________________ "A Certification flight will only be considered if the certifying vehicle employs a parachute as the primary means of recovery." _________________________________________

As a result, certifying flights that use aerodynamic drag as the prime recovery method will not be permitted in the future. In that: A main parachute must be employed to safely recover a certifying flyers airframe to earth.

UKRA should make it clear that this does not impact flyers wishing to safely fly airframes using drag recovery after they have successfully certified.

UKRA will honour any certification flights that have taken place, prior to today's amendment, from flyers that have gained their certification using aerodynamic drag as their main means of recovery.

UKRA Safety and Technical Committee are of the view that flyers should demonstrate a degree of competence with conventional recovery methods in order to gain access to insurance cover at higher power levels. We feel that this is in the best interests of the UK rocketry community as a whole.

Kind Regards

Damian Hall, on behalf of UKRA Safety and Technical Committee.

Apologies to all.

I neglected to change my identity prior to sending the last post. How embarrassing!

Because the name is changed the results remain the same?

I'm curious to know what sorts of parachutes you use that don't rely on aerodynamic drag....

This is truly good news. In my time on council i brought to the meetings my concerns over the use of alternative recovery methods such as saucers that do not deploy and separate method of recovery as not fully covering the spirit of the certification wich is after all to demonstrate some level of competance.

This brings us inline with tripoli who have not aloud drag recovery as the primary method of recovery for cert flights for some time now.

The concern i think is mainly to do with the use of saucers that don't deploy any form of recovery being used for cert flights as they don't really demonstrate any competance.

A flyer could cert L1 & L2 with saucers and never had to deploy a chute at any point and then be able to fly a big M motor.

I know Tripoli don't allow saucer only recovery method for certs, i remember getting an email from tripoli a while back when i questioned it in comaprison to our cert system.

Personally i would like to see dual deployment being madatory at level 2 or at least level 3.

What about a large boost glider R/C type?

That's the whole point.... to force new innovation, and speed up the development of anti-gravity research. Plus, it makes the job of being a spectator a whole lot more fun when you have to dodge all the failures.

what about streamers?

Not that I have anything against parachutes, some of my best friends were US T10's and MC4's. But there are alternate methods of recovery.

It's been a long night. That's my excuse anyway!

There is no such rule in TRA. However, some certification officials have taken it upon themselves to enforce the rule, even though it is not yet on the books..

I'd like to see the streamer you use on the L2 & L3 projects. 8-)

Who's concerned? BTW, designing a form of rocket that uses a recovery system other than a parachute, that safely recovers a rocket, requires and demonstrates extraordinary competence...

Who in TRA sent you that email??

Ha, but streamers must be deployed, so streamers will not be on the list..

You say that like it is a good thing.

That's allowed in Tripoli?

Making up the rules as you go along?

Point!!

Hopefully in a saucer!

Also plenty of CERTIFIED users cannot successfully deploy a chute. I thought the point of certifying (what do I know? I was only there when it was invented and personally certified the very first TRA members) is you can get a motor and airframe COMBINATION to work at all in light of motor handling and aerodynamic force issues.

In the past (what do I know? I was only there when it was invented and personally certified the very first TRA members), ANY recovery system, whatever it might be, simply had to function as designed.

DECIDING what to fly is part of the certification practice!
