"Experimental" On Initial Contact With Tower

[Auburntsts]

Simple advisory message. Like a pilot has to brief a passenger of the experimental nature of the aircraft before taking off.

No, not outdated at all.

Maybe not outdated but I question the usefulness for 2 reasons:

1. The rule applies only to towers and no other ATC facilities. Even though I fly IFR a lot, I can easily go on dozens of flights before I go on one where I need to talk to a tower.

2. Experimental, as a category, is meaningless by itself due to the huge range of aircraft performance that it encompasses. Plus Experimentals are quite common in many areas these days, at least compared to back in the day, so they aren't so unique to require the advisory, IMO.

Having said that, I comply with 91.319 (and my OPLIMs too as mine has the same requirement as the reg with regards to this) by prefacing my initial call to any tower with "Experimental RV 728TT...". Thereafter I drop the "Experimental" from all other subsequent communications and never use it all with Approach or Center.
