Heading 145 , is it OK ?

Hello Guys
Well , this is my first post here in this nice forum and really excited to get beneficial from each other in our passion
I am wondering if its okay or not that ATC gives you for ex( turn left heading 145 ) instead of 140
is that okay ? is it okay to take heading not ending with 0 ? that is my point and I will be happy if there is any reference to that

I used headings ending in 5 on a reasonably regular basis. Also continue current heading - which may be 147.

SA: are you an ATCO asking pilots, or the other way around? ;) Welcome to the site and enjoy.

I don't have any international source to hand, but from CAP413 (UK RT Manual), the follow implies a heading need not end in a zero.

Quote:

For all transmissions, with the exception of those used for surveillance radar approaches or precision radar approaches, the word ‘degrees’ shall be appended to heading figures where the heading ends in zero, or in cases where confusion or ambiguity may result.

It’s defensive controlling. It distinguishes between headings and flight levels (which, in controlled airspace, usually end in a zero).

e.g. Turn right heading 295(degrees), climb flight level 260.

The “degrees” above is not mandatory (as in this case the heading ends in a 5).

In theory it’s to prevent level busts (where a crew could select the heading as a flight level, and vice versa).

During a ground controlled approach to a runway, such as a PAR (Precision Aproach Radar, not often provided these days) it was quite routine to be given a heading change of only two or three degrees to maintain the centreline.

Three hundred and sixty degrees to choose from, use them wisely!

Except in the Royal Navy where they would often give a 1 deg heading change.

Well, the world doesn't say degrees, altitude, millibars and so on...... It doesn't bother me, but I do either don't need the aircraft type.

I tend to only use headings ending in '5' so that I can drop the 'degrees'. I also frequently use 1 degree increment headings when providing an SRA.

I used to do that in my last few years; got the habit from Terminal Control.
