Hi: Anyone tell me what fly right base or left base means, and what fly over the numbers means? Thanks, Adkad

Let's see how too put this.

Every runway has a square Traffic pattern that most aircraft fly when comming into an airport, and it consists of an Upwind, Crosswind, Downwind, Base, and Final legs.

If an Aircraft takes off on runway 36 we'll say, he is heading 360* when he takes off, this is the Upwind leg. If he makes a right turn to heading 090* he is now on a Right crosswind for runway 36. Now about 1/4 mile out he'll turn right to 180* to enter a Right downwind for runway 36 which if you notice he is now parallel to the runway going the oppisite way on the right side of the runway. he will then turn right again to a heading of 270* which puts him on a Right Base for runway 36. and then one final turn to the right to a heading of 360* now puts him on Final for runway 36. If he were to do this on the Left side of the runway, and all turns are to the left, then he'll be on a Left traffic. Hope that kind of makes sense.

Very good picture and explaination here: http://en.wikipedia.org/wiki/Traffic_pattern

Now with the saying Fly over the numbers, it usually is that the controller is asking the Pilot to fly to a traffic pattern for a Parallel runway Say 36L from the pattern of 36R and he want the pilot to fly his base leg right over the threshold (area where the big numbers are painted.) and cross at 90* to the runway. or The controller wants the pilot to fly his Downwind Leg over the numbers of a Perpendicular runway.

Hope that helps a little, Let me know if you have more questions,
Kevin

Thanks Kevin. That does help. It was hard to picture it in my mind before but I think I have it. Last question-can you tell what is meant when the controller asks the pilot to "ident". Thanks, Adkad

I'm not Kevin, but I should be able to help with your question.

When a pilot is asked to "ident" he is being asked to press the IDENT button on his transponder. This will flash a symbol/message on the controller's scope and allow him to easily identify the plane on his cluttered display. Typically a controller will ask a flight to "Squawk XXXX and ident" which is instructing the pilot to change/confirm the Squawk code and then press the ident button.

Here is the official answer - http://www.faa.gov/ATpubs/ATC/Chp5/atc0503.html

Hope this helps!

Hey Chris-M: ever land your 757 on a 6000ft runway? The Ga Tech and Fla State football teams come here to CHO on a 757 and its a tight fit! On takeoff they have to do the old powerup with the brakes on before you roll. Also saw one of the SAM flights from Andrews doing touch and go at CHO in a 757. It looked like a leaf blower behind him when he lifted! Don't see big planes here very often, mostly Dash8 and RJ with a mix of corporate jets. Seeing a Gulfstream-V next to a Dash8 makes you realize how big that thing is too. Some people have all the fun!

Nope, I haven't been into Charlottesville. Getting in and out of 6,000' with a modern high-bypass 757 would be a snap though. How about landing and taking off from 6,006' of wet, coral-based asphalt (slippery, and not grooved) in a Boeing 727. Water at both ends of the runway. When flying the 'Island Hopper' or the 'Night Truk-Phonpei' runs, it was the norm. Consider the old-tech brakes on a 727, and how underpowered (compared to a 757) the 727 is and one can appreciate that effort! We 'spun' the weight and balance with a big whizz wheel to get out with as much cargo and pax that we could using 25-flap takeoffs and holding the brakes while the engines spooled up to full thrust. The CMI 727s were powered with JT8D-15 or -17 engines, which were higher thrust than the common -7 and -9 power used in the mainland.

It was a blast and I'm glad I was able to experience it from 1995-1998 out in the Guam base.

Here are some pics from somebody else's site that I found with images of the Island Hopper airports.

Squawk and Ident

DavidNVA had an accurate reply to your question.

This is what the antennas look like:
Bottom reflector is the "Primary Radar" antenna and gives the approach / departure controllers the raw radar video. The antenna on top of the main reflector is the "Secondary Radar" or beacon antenna that interrogates the aircraft's transponder and will paint the controller's display with the requested squawk numbers and altitude. When the pilot hits the "Ident" button on their transponder, the corresponding image will flash a special symbol, to make it easier for the controller to find the aircraft.

The radar system pictured here is seen at a lot of major airports and air bases, and typically has a 60 nautical mile range.

I used to work with this equipment in the 1980's and whenever a system was down for maintenance you would hear the controllers telling aircraft quite often that they were only viewing primary or secondary radar, to give the pilots a little warning to be on their toes.
