Thunder
The sound
emitted by rapidly expanding gases along the channel of a lightning
discharge. Over three-quarters of lightning's electrical discharge
is used in heating the gases in the atmosphere in and immediately
around the visible channel. Temperatures can rise to over 10,000
°C in microseconds, resulting in a violent pressure
wave, composed of compression and rarefaction. The rumble of
thunder is created as one's ear catches other parts of the
discharge, the part of the lightning flash nearest registering
first, then the parts further away.
Aero-Linx: ADS-B
Rulemaking
On May 27, 2010, the FAA published new rules contained in 14 CFR
§92.225 and §91.227 mandating airspace and avionics
performance requirements after January 1, 2020. The avionics
perform a function that is generally known as “ADS-B
Out” which transmits precise location and other information
about the aircraft to ground stations and other ADS-B equipped
aircraft.
"The expense of running this aircraft is significantly
lower than our aging aircraft. The older an aircraft gets, the more
expensive it is to maintain it..."

manager for Utility Helicopters at Redstone Arsenal, AL, commenting
on the introduction of the latest version of the Lakota, the
security and support model.
