Make Landing in the Windy City a Breeze!

Make Landing in the Windy City a Breeze!

It’s not just the winds that make landing in the Windy City a challenge, especially if you’re flying into Chicago Executive (KPWK).

There’s always a good chance the winds will favor Runway 34. The problem is, there’s no approach to that runway except for a circle from Runway 16 and 30, with relatively high circling minima. Add to that ORD’s Class B airspace is just 5 miles south of KPWK, and there’s a 5,000-foot runway to take into consideration, and you have a recipe for a challenging landing, no matter how experienced you are.

Fortunately, there’s a better option.

Honeywell’s RNAV (RNP), also called RNP-AR, was developed for airports just like this. The RNAV (RNP) approach for Runway 34 provides minima down to a DA (H) of 271’ and a comfortable 3.2° glide path. Whether you’re navigating mountainous terrain or Class B airspace, the lateral and vertical precision of RNAV (RNP) provides stable guidance down to the runway. 

Eligibility for the Approach

To get approval for the KPWK RNAV (RNP) approach you need a qualified aircraft, qualified pilots and proper regulatory approval: FAA letters of authorizations (LOA) or operations specifications. Operators of non-US registered aircraft should consult their regulatory guidance for RNAV (RNP) and special instrument approaches.

Aircraft Qualification
Eligible aircraft must be certified for:

  • RNAV (RNP) to RNP 0.3 or RNP 0.1 lines of minima.
  • Radius to Fix (RF) legs.

 

Pilot Qualification
Both pilots must:

  • Be trained for RNAV (RNP) using a training program approved by the regulatory agency.  For operators of US-registered aircraft, this is already a requirement of LOA C384.
  • Review the KPWK RNAV (RNP) briefing package prior to using the approach. An approved briefing package is available from Honeywell.

Regulatory Approval

Honeywell’s KPWK RNAV (RNP) approach is considered a “special” because distribution of the procedure is restricted to authorized users. Operators of US-registered aircraft will need the following approvals:

  • LOA/Ops Spec C384 – Approval for RNAV (RNP) Approach Operations.
  • LOA/Ops Spec C081 – Approval for Special Instrument Flight Procedures.

Customers with non-US registered aircraft should contact their regulatory authority for approval requirements.

 

Current RNP Customers

If you’re already RNAV (RNP) authorized in your Honeywell equipped aircraft, the KPWK RNAV (RNP) is included in your navigation database. Just work with your FSDO to get the approach added to your C081 approval.

 

Future RNP Customers

If you’d like access to this and other RNP-AR approaches or just want to learn more, visit our RNP-AR webpage or contact us. Honeywell offers RNP consultancy services that make the approval process easy, with everything you’ll need to start flying Chicago Executive, Aspen and the 400 public RNAV (RNP) approaches currently available.
