Craig is correct and I am guilty.
To the non-pilots.....from time to time you need to slap us up side the head. Almost everything in aviation is in acronyms, abbreviations, or some sort of code. Instead of giving us weather in plain English, we get Metars (local current weather) and TAFs (a forecast for an airport) and it is a string of numbers and letters. Our flight plans are in blocks of numerals or letters and numerals. So as you can see we are programmed to speak in "pilot".
Here are a few of the common "codes" explained. VFR means visual flight rules. That is how a flight is conducted and for a pilot to fly under those rules certain weather minimums must be met, such as 3 miles visibility and at least a 1000 foot ceiling. A pilot that flies visually in those conditions however is pushing the limit and most will fly only when the weather is better than that.
IFR means instrument flight rules. With the exception of landing minimums which can be as low as 1/2 mile visibility and a 200 foot ceiling, a pilot flying under IFR conditions can be in conditions in which he has absolutely no visual references outside the plane and he must rely on his instruments.
Range is how far a pilot will or can fly. Endurance is similar, but is expressed in terms of time. I typically can fly a maximum range of 600 miles, depending on the direction and intensity of the winds aloft, but because of fuel available my endurance is 4 hours, at which point I must be on the ground to refuel. That is a personal limit, but the FAA also stipulates fuel requirements and they are abolute requirements.
Weight and balance is a phrase often written as W&B, and before each flight a pilot must do a weight and balance calculation to insure the plane is within its gross weight limits and the load is such that the plane is within its specific center of gravity (CG) range.
We as pilots have all sorts of obscure ways of talking. Public domestic airports all have identifiers. They can be a combination of letters and numbers such as TN20 which is Seymour Airpark a small grass runway near Sevierville TN, or KTYS which is McGee Tyson Airport, the large airport which serves Knoxville, TN.
We use GPS to navigate. That is now a means common to car navigation so that should be understandable, but we also use VORs and NDBs, which are ground based aids to navigation that we can track to or from using radios in our planes. Some planes have APs (autopilots), MFDs (multi function displays), and almost every plane has NavComs which are combination radios for both communications and navigation.
A plane that is KI equipped and certified has equipment to deal with airframe icing. Icing is for whiskey and the devices are to enable the pilot to have some time to extricate him or herself from icing conditions which are a bad thing. Some planes have a StormScope or a Strikefinder. These devices map lightning strikes. Some planes have radar. Radar maps precipitation and can be used to discern light rain from heavy rain. These devices can help keep a pilot from thunderstorms, more conditions which are bad things.
The list can go on, but the important thing to remember is if in doubt, ask. Remember, every pilot and every plane is different so even if you understand the lingo, we still may not all be on the same wavelength.
Now, for you rescues....we pilots also do not understand your code words and lingo sometimes. I hear words and phrases that I assume relate to illnesses or breed specific terms and I may need your help in sorting out the code.
