You could expect the standard ICAO intercept procedures.... think back to air law exam - Wing waggling etc. Albeit in a series a passes as they come past you. There would be a sharp break away after each pass so you knew not to follow. ie. First pass he wing waggles, you do the same (to show you're complying) he then breaks hard up and away and repositions behind. Second pass - alongside then gentle turn away which you follow, when he breaks away roll out and fly in a straight line. If he needs you to do more turn he'll come past again. You can get a FJ quite slow... think back to air shows and the slow passes. Although you can still accept a fair bit of overtake if you're doing 100kts. Hope that helps.
The Tucano incident was right place right time with the right experienced instructor on board. Not something that is trained for. We have QRA for that. + a Tucano can’t find you and intercept you IMC unlike QRA.
