E3D ZH101 Altimeter in Inches
Can any of you aircrew answer this question? Today, I (a humble air trafficker) spoke to an E3D (as it had a UK Mil reg and was a 8/23 sqn aircraft), and although it was a Brit aircraft (albeit with a non-UK sounding pilot (exchange?)), its altimeter was in inches rather than Mb. Can any one explain? Cheers.
