Glide Slope

[Air Jamaica]

Hey guys i have a question i always here approch ATC tell a pilot that they must leave 5 on the glide slope, what does that mean. I know what a glide slope is but what does it mean to leave 5 on it?. thank you.

Hear this at Pearson, don't ya. It means the aircraft is to maintain 5,000 feet, then when they intercept the glideslope, to begin descending on it.

I just realized something... all this time I've known it as "glide scope" for some unknown reason.  I learned something new today...

Kind of like when you read the actual lyrics to a song that you had been singing wrong all those years:

"Must leave 5 on the glideslope?"

That sounds odd. Usually, at least in the US, we say, "Southwest 558 turn left heading 260 maintain 2300 until established on the localizer, cleared ILS 23 approach."

Interesting.

Ya that sounds like pretty sub-par phraseology, but then again its canada and things might be different there than what I am used to. 

[Greg01]

Well, I think the US is the exception rather than the rule, if you will.

For example, we say: "ASH2816, runway 23, taxi into position and hold."

In other countries, it'll most likely go like: "ASH2816, runway 23, line up and wait."

So....

Wow Greg you must be an old-timer, the procedure is called Taxi into Position and Hold but the phraseology is "position and hold."  They changed it about 5 years ago.

3-9-4. TAXI INTO POSITION AND HOLD (TIPH)

a. The intent of TIPH is to position aircraft for an imminent departure. Authorize an aircraft to taxi into position and hold, except as restricted in subpara f, when takeoff clearance cannot be issued because of traffic. Issue traffic information to any aircraft so authorized. Traffic information may be omitted when the traffic is another aircraft which has landed on or is taking off the same runway and is clearly visible to the holding aircraft. Do not use conditional phrases such as "behind landing traffic" or "after the departing aircraft."

b. USN NOT APPLICABLE. First state the runway number followed by the taxi into position clearance when more than one runway is active.

PHRASEOLOGY-
RUNWAY (number), POSITION AND HOLD.

Or, when only one runway is active:

POSITION AND HOLD.

EXAMPLE-"United Five, runway one eight, position and hold. Traffic a Boeing Seven Thirty Seven, six mile final."

JD,

I'm 17 years old. 

I couldn't remember if they specifically said "taxi into..." or just "position and hold" as my intern at BUF happened after they stopped TIPH...and we didn't have a waiver.

Thanks,
Greg
