MISSED APPROACH−
Maneuver conducted when an instrument approach cannot be completed
ON COURSE−
Aircraft is established on the route centerline
OUT− Conversation is ended and no response is expected.
OVER− My transmission is ended; I expect a response.
PAN-PAN: Used by pilots to indicate something unusual with the aircraft that stops short of an immediate
emergency. When repeated three times, it indicates urgency and attention.
REQUEST FULL ROUTE CLEARANCE− Request that the entire route of flight be re
ad verbatim in an ATC
clearance.
RUNWAY− Defined landing and takeoff area. Runways are normally numbered in relation to their
magnetic direction rounded off to the nearest 10 degrees.
SIGMET (SIGNIFICANT METEOROLOGICAL INFORMATION)
−
A weather advisory issued concerning
weather significant to the safety of aircraft.
SQUAWK (Mode, Code, Function) − Specific modes/codes/functions on the aircraft transponder.
VFR (VISUAL FLIGHT RULES) - Rules for conducting flight under visual conditions. Also used to indicate
weather conditions that are equal to or better than minimum VFR requirements.
STAND BY− Request to pause for a few seconds, usually to attend to other duties of a higher priority. Also
means to wait as in “stand by for clearance.”
SUPER – An aircraft above “heavy” class. The Airbus A-380-800 (A388) is classified as super.
WILCO− I have received your message, understand it, and will comply with it.

US Law Regarding Use of Personal Electronic Devices Onboard Aircraft
In the US, the FCC (Federal Communications Commission) has jurisdiction over any RF-emitting electronic
device, and the FAA (Federal Aviation Administration) has jurisdiction on electronic devices in use on
board aircraft.
The PABM1 Passive Air Band Monitor does not have an internal RF oscillator, and does not emit RF energy
above 9 kHz, so it is exempt from FCC registration.
The FAA rules about using the PABM1 onboard aircraft is not straightforward. Section 91.21—formerly §
91.19—was established in May 1961 to prohibit the operation of FM receivers on board aircraft since they
were determined to interfere with the operation of navigation and communication systems. The FAA
subsequently determined other personal electronic devices (PEDs) could be potentially hazardous to
aircraft systems if operated aboard aircraft. Amendment 91-35 amended the scope of former § 91.19 to
prohibit the use of additional PEDs aboard certain U.S.-registered civil aircraft. Section 91.21, as adopted,
was drafted to require the air carrier or commercial operator to determine whether a particular PED will
cause radio frequency (RF) interference when operated aboard its aircraft. This AC uses the term
“operator” throughout to mean pilot in command (PIC), renter-pilot, or air carrier certificate holder.
