View Full Version : ICAO speeds etc

4th Jun 2004, 20:37
FAA holding speeds are MHA-6000' 200KIAS
6001-14000' 230 '
14001- above 265

So i read somewhere else that ICAO speeds for holding are
<14000 230kts, 14-20000 240kts, 20000-34000 265kts, >34000 .83M

So who's using what speeds and where?

Also, is there an internet address that lists the range of speeds for the categories of aircraft; Initial approach, final approach, missed, visual manouvering etc?? Speeds are.....

Hi Maxpower. May I add that those are MAXIMUM holding speeds?
Second, not flying heavy iron, I'm able to just use 200 kias as my personal max speed, and that way don't have to bother memorizing speeds/altitudes/countries from the Jepp publications.

Reference range of speeds for the approach segments (pan ops only, I presume. I've never seen this for US/Canada) I don't know of internet locations, but again, the Jepp has them listed.

Hi Maxpower,

The speeds you mention are TERPS and this is used only in USA or its 'teritories' ie Guam...etc

The ICAO speeds are based on PANS OPS . This is from ICAO Doc 8168.

On the approach chart bottom left border you will notice annotations as to whether the approach requires Terps, Pans Ops, Pans Ops 3 or Pans Ops 4.

Pans Ops 3 is just a change of Holding Speeds above 14000' from Pans ops.
Pans Ops 4 is that the acceleration segmet on MAP has been deleted or rather not applicable.

In short, the Holding speeds for Pans Ops for Cat D a/c are:
<6000' - 210k, 6000' to 14000' - 220k, >14000' - 240k

MAP speeds Cat D : Intermediate 185k and Final 265k

Both Terps and Pans ops have diffrent circling calculation for the minima. Terps is based on an ostacle height of 300' whereas Pans ops 394'. So they have diffrent minima and safe radius.

Web sites I'm not sure of but all this info is in the Jepp ref manual.

Hope this helps:ok:

alright, i appreciate the replies here.

Its just that i've got an international airline interview next week, and from what others are saying, these are asked. I only have a FAR Aim book.

specifically, the range of speeds for initial, intermediate, final approach ,vis manouvering etc, max speeds for missed
for cat a,b,c,d,e,

Would they ask me these if i'm from the usa.


good weekend:ok:

Does the airline have any Cat A, B, C or E aircraft? There lies your answer i suppose!

If you are going to try to remember all these speeds is there enough memory for other stuff like....Fleet size? ....Destinations? Wing span?....engine power output?......seating capacity?....what is mach crit?.....what happens to the c of g after mach crit?...whats V2?...whats swept back?...what are the winglets for?what happens if one is not there? if two not there?....types of flaps on 747,777?...what is super crit wing?...when do you change kts to Mach?...what is RVSM and the altimeter limits or Nav equip req?.....How about RNP?.... man the list goes on!

If you want to learn these speeds i personally think Cat D.

Good Luck with the interview:ok:

Hi all,

Did I read somewhere that the FAA maximum holding speeds are different in New York and Washington DC, 5 or 10 slower!

Just a thought!

Well, I can tell you there are a few differences for Canada from the FAA norms, namely:

Propeller Aircraft (including turboprop)
MHA to 30000 feet 175 KIAS

Civil Turbojet
MHA to 14000 feet 230 KIAS
above 14000 feet 265 KIAS

Climbing when in holding pattern
Turboprop Aircraft Normal climb speed
jet aircraft 310 KIAS or less

There are some differences for military turbojet aircraft also.

Note that the holding speeds in the UK differ from ICAO standard. I can't find that bit of the AK AIP on line at the moment so I can't post the accurate data for all Cats. But it should be in the Jepps.

From memory, for Cat A and B, they are

Up to 14k 230kts
14k to 20k 240kts
20k to 34k 265kts

Unless the hold is part of a procedure where the speed is promulgated as being higher.

I know it is a bit sad remembering these but we had the ops inspector fly with us only yesterday and he asked me this exact question. I could not answer it which is why it is fresh in my memory now!

high speed descent.

Thanks for your input.
I have been studying alot (HBJ, pprune, etc), and you know what, each time i think i'm starting to cover alot of material, i come across more questions i havn't seen before??.

I don't know what rvsm is, or kts to mach, so off to the books,,

see ya:ouch:
