10,000 After Take-off?

Are airliners generally cleared to 10,000 after take-off? Is this the normal operating procedure? But some DPs have altitude restrictions below 10,000, right? Thanks for the comments.

Most SIDs ( Standard Instrument Departure) have altitude restrictions upon T.O.

For example my airport (YEG) SID clears you to 7000 ASL after T.O.

10,000 feet is a "magical" figure as noise abatement restrictions are in affect until 10K... at least the 250kt restriction. I believe it is also when you change the altimeter setting to 29.92??? Although I'm not sure...

Thanks for the info. Transition altitude is FL180. But does that altitude apply to all countries worldwide?

Thanks for the FL180... now that you mention it, It comes back to me....

Although I was just looking in a ATP training manual which states to set 29.92 just prior to reaching desired altitude??

Transition altitude is not always 18,000 feet. It depends what country you are flying in. Some countries are 10,000 feet.

Airliners departure clearance altitudes are directly related to the airspace physical structure, and what agency is controlling. It is different for every airport.

Noise abatment altitudes can be found in the departure procedure, and is seldom applicable after 1,000 feet AGL.

All SID's contain an altitude limit as a SID is a departure clearance.

Think of it as different air traffic control facilities "own" different chunks of the sky. When an airplane is handed off between one facility to another, they usually do it at or near the imaginary boundery between the two's airspace. Because some tracons "own" airspace up to a higher altitude, they might clear you up to a higher altitude initially/prior to handoff then others. In Miami, you will be climbed to 16000 prior to handoff. In Orlando, its up to 12000 prior to handoff. In some smaller airports, you may only get cleared to 8000 or 9000.

In Anchorage you usually get cleared to 20000.

OBAMA-WORST PRESIDENT EVER....Even SKOORB would be better.

Flights to the east and north out of SFO and OAK used to get FL230 in their predeparture clearance (with the 2000-ft crossing-restriction out of OAK), but no more. As I recall it's now 15000 ft.

SFO: departures from runways 1 ordinarily get initial clearance to 15000 ft, I think. For some reason departures from 28 only get 3000 initially.

OAK: runway 29 departures to N and E get 15000 initial, except cross 4 DME at or below 2000 (keeping them below SFO rwy 1 departures). Flights to the S will be crossing beneath Golden Gate arrivals into SFO at 11000, so they only get 10000 initial, along with the 2000 crossing restriction.

SJC: runway 30 departures get 5000 ft initial, presumably so that Modesto arrivals into SFO can be cleared to 6000 above them.

A couple of months ago I was scanning at CLE and heard an ERJ-145 pilot ask for clearance to 12,000 at departure. After a few exchanges for verification, he got the clearance. He explained then that they were flying an empty plane. I'll tell you, that ERJ went up like a rocket -- almost like a DC-9!

Attn: Timz

Actually 30L departures out of SJC headed for the North and East actually climb and cross above the arrival flow into SFO. Aircraft flying the Loupe9 departure make a right s/b within 3 miles after departure and then make another right turn to pass back over the SJC VOR at 15,000 and are then cleared on course, usually to Red Bluff or Linden VOR's.

As I recall Flygga and I are both right-- SJC departures are initially restricted below SFO-arrival airspace and then circle and climb above it. In any case the initial clearance is to 5000 ft.

After crossing the VOR, flights routed over Sacramento or Linden continue north for 20 miles or so before being cleared to turn NE or ENE, presumably to keep them clear of SFO-OAK arrivals from the east.
