”Is this a new procedure or a change to an existing procedure? or
Are you trying to gain approval to operate to lower minima on an existing procedure that has OCH limited by obstacles in the Missed Approach?”
No – this is not a new approach. It was first flown about 10 years ago and has been flown by at least 9 Air Carriers since. It is a “special” approach requiring authorization due to the 8% gradient on the published miss for the approach. In fact I saw the same flight path for the OEI miss, shown on a Western Airlines procedure for this runway, (for takeoff) dated over 30 years ago.
”If there is an existing procedure are you simply designing an alternative missed approach for the OEI case?”
No – this is the same OEI flight path that other carriers have used – not sure of all or them used the exact same procedures – but some did.
”What type of approach?”
ILS
”How can you say that flight checking of the nav aid is not a factor?”
The referenced nav aid is a DME at the field used straight out until less than 5 miles – then headings are flown until passing abeam and very close to another nav aid almost on the field. I can’t see that signal reception would be a factor.
Sincerely,
