LBA Jet proceudres
 

Can any one help?

In the UK AIP when departing rwy32 at LBA, it says that no turn should be made until 500ft aal. However, it also advises a left turn to 314MAG at 0.5DME. However the jet reaches this turning point before 500ft aal, what to do?

Perhaps older coal burning ex Australian ones may, but newer French jets should be OK :E

A departure where the track is 15deg or less from the runway centerline is considered to be a straight departure. Thus the first "turn" in the procedure is at 2.1 DME ILF.

If one looks at a simple version of the numbers for obstacle clearance.

Climbing at 3.2% (there is no higher gradient specified for obstacle clearance) would take about 2.6nm from the DER to reach 500ft above DER.

Thus I understand the restriction is not to make the turn at 2.1dme unless at or above 500ft above DER.
