Couldn't add much more than the good stuff already posted. I agree especially with the 400ft/40kts; 300ft/30kts etc. This works very well in poor weather as something to hang your hat on and encourages the scanning of the ASI which is half of the problem sorted.
We used to be required to hover at up to FL100 in a previous job. No radalt goes that high, although we did have a doppler "along & across" hovermeter for the RHS only. When flying from the LHS we used to watch the digital doppler readout and aim for "all the zeros". We flew at whatever altitude we could get at max. continuous power. All manual stuff, up to 2 and a half hours flight time depending on fuel load. Pretty unreal stuff at times. Improved the IF scan no end, though.
War stories again...sorry!
