Back to Asia again, great place to pick up experience quickly, just out of Jakarta on the SID when radar tells me " N-#####, traffic, your six o'clock' climbing through your level, its an Airbus"
Only option, sit tight and hope he's got his TCAS on, as it was I saw him steam past me on the right about a mile offset.
Skyhawk a faster, more powerful aircraft behind you on final, will also be above you on the GS, and will probably be motivated to enter a climb in order to avoid spearing you (pilot is always the first at the scene of the accident) and will convert speed in to a climb rate that you can only dream of. So don't worry
More worrying is some xponder-less tw3t who cuts right across your GS when you are on a longish final, mistakenly thinking that he is transiting outside the zone. Now that has happened to me a few times, once close enough to encourage a change of underwear after landing
