With 10,000+hrs on helicopters, with one ACFT having an odd ball French military70mm primary attitude indicator requiring a dispensation from the department, guess they have a problem with it too. If you can only fit one 80mm instrument into your panel, perhaps it should be the ASI? -- Kind regards Daryl Mackay
