Aviation disclaimer
Last updated 2026-07-31
Everything Conaer produces is advisory. It is not for navigation and it is not a dispatch release.
Conaer is not an FAA approved source and it is not a certified system. The certificate holder, the aircraft dispatcher and the pilot in command stay responsible for every flight, exactly as they were before this tool existed.
This page is the one we would want you to read first. It is short on purpose, and we mean every line of it.
Advisory only
The Alternate Engine tells you what it computed and why it computed it. That is the whole of what it does. It is a second set of eyes on a decision you are already qualified to make, and it does not make the decision.
- Not for navigation. Nothing here is a navigation source. Do not fly a route, an approach, a minimum or an altitude because this app showed it to you. Use your approved charts and your approved avionics.
- Not a dispatch release. Output from this app is not a dispatch release, is not part of one, and does not become one. A dispatch release is prepared and signed under 14 CFR 121.663 and carries the contents required by 14 CFR 121.687.
- Not a flight plan and not a weather briefing. Get those from the sources your operator and the FAA require.
- Not an approved performance or fuel calculation. Route and time estimates in this app are rough planning aids only.
Not an FAA approved source
Conaer has no FAA design approval, no technical standard order authorization and no type certificate. No part of this product has been certified by the FAA or by any other civil aviation authority. It is not approved avionics, it is not an approved dispatch system, and it is not named in the operations specifications of any operator unless that operator has put it there and has the authorization to do so.
Advisory software of this kind is normally evaluated and authorized by the operator, not design approved by the regulator. FAA Advisory Circular 120-76E describes that split for electronic flight bag applications: they carry no certification requirement for installation, they cannot replace equipment that regulations require, and the operator is responsible for evaluating what it authorizes. Treat Conaer the same way. If your operator has not evaluated and authorized it, it is a personal reference tool and nothing more.
Who stays responsible
Nothing on this site relieves anybody of a regulatory duty. Under 14 CFR Part 121 those duties sit with named people and with the certificate holder, and a piece of software cannot hold them, discharge them or share them.
The certificate holder conducting domestic operations is responsible for operational control. The pilot in command and the aircraft dispatcher are jointly responsible for preflight planning, delay and dispatch release. The dispatcher monitors the progress of each flight, issues the information necessary for its safety, and cancels or redispatches when the flight cannot operate safely as planned. The pilot in command is in command of the aircraft and crew during flight time and is responsible for the safety of the passengers, crewmembers, cargo and airplane.
The certificate holder prepares a dispatch release based on information furnished by an authorized aircraft dispatcher. The pilot in command and an authorized dispatcher sign the release only if they both believe the flight can be made with safety. A dispatcher may delegate authority to sign a release for a particular flight, but may not delegate the authority to dispatch.
The dispatch release has to contain the aircraft identification, the trip number, the departure airport, intermediate stops, destination and alternate airports, the type of operation, the minimum fuel supply, and the weather reports and forecasts for the airports concerned, which must be the latest available at the time the release is signed.
A dispatch release for an IFR or over-the-top flight has to list at least one alternate airport, unless the reports or forecasts show that for at least one hour before and one hour after the estimated time of arrival the ceiling will be at least 2,000 feet above airport elevation and the visibility will be at least 3 statute miles.
An airport may not be listed as an alternate in the dispatch release unless the weather reports or forecasts show that, at the expected time of arrival, the weather there will be at or above the alternate weather minima in the operations specifications of that certificate holder.
Read those five sections and you will notice something. Every one of them puts the duty on a person or on the certificate holder. Signing a release because a screen said the airport qualified is not compliance, and we would not want you to treat it that way. If the engine and your judgement disagree, your judgement and your operator procedures win.
Data can be stale or wrong
We build from public FAA and NOAA sources, and we cache what we fetch so the app stays quick and stays usable when a source is down. Cached data ages. Feeds fail. Publication cycles move. Our parsing of a chart or an operations specifications paragraph can be wrong, and we will not always know it is wrong.
The official sources of record are, and remain:
- FAA publications: the charts, the Chart Supplement, NOTAMs, the Aeronautical Information Manual, and the aeronautical data the FAA publishes on its own cycle
- NOAA and National Weather Service products, including METAR, TAF and the aviation weather products issued by the Aviation Weather Center
- The operations specifications issued to your certificate holder
- Your operator manuals and procedures
Where Conaer and any of those disagree, they are right and we are wrong. Please tell us when you catch one. A report from a working dispatcher is the fastest way a defect gets fixed.
The study products
Conaer Ground School, Dispatch Prep, the trainer at /fly and the safety management trainer at /sms are study aids. They are built from public FAA material such as the Airman Certification Standards, the FAA handbooks including the PHAK, the Aeronautical Information Manual and the Code of Federal Regulations.
- They are not FAA approved courses and they are not an approved training program under Part 121, Part 135, Part 141 or Part 142.
- They do not substitute for a certificated flight instructor, a ground instructor, an authorized training provider or a check airman.
- They do not provide any endorsement, sign off, certificate, rating or currency credit.
- They are not a substitute for the current FAA publications. Where a question, an explanation or a citation here disagrees with the current FAA source, the FAA source is correct.
- Passing a drill here is not evidence that you will pass a knowledge test, a practical test or an interview.
Availability
We do not guarantee that Conaer will be available, that data feeds will be reachable, or that any part of it will work at a particular moment. It runs on one host and it depends on external sources we do not control. Plan your operation so that Conaer being down changes nothing about your ability to dispatch a flight or study for a test.
