Description of the Rally
The annual Air Rally gives aviators a chance to test their flight planning, navigation and pilotage skills. The rally course consists of two legs, each up to 250-300 nautical miles. While the endpoint of each leg is known beforehand, the actual course is kept secret until the day before the rally. Past years' courses can be found here.
In 2017, our two course legs will be:
- Hayward (HWD) to Redding (RDD)
- Redding to Reno-Stead (RTS)
On each leg of the course, there are several checkpoints which must be identified. There is also an airborne timing line near the destination airport for each leg that must be overflown. Prior to departure from Hayward each pilot turns in estimates of their expected flight time (takeoff to timing line) and fuel consumption (engine start to shutdown) for each of the two legs.
Rally participants are scored on a combination of:
- Checkpoint Identification
- Matching Predicted Time
- Matching Predicted Fuel Used
Sound easy? In recent years, rally winners have correctly identifed all course checkpoints, and generally been within 15 seconds and 1% of fuel consumption on each of the two rally legs!
Classes of Entry
Rally crews have a choice between four classes of entry. In a nutshell, the choices are:
- Analog or Digital for navigation (timing) and
- Analog or Digital for fuel consumption
If your aircraft is equipped with aftermarket GPS or digital fuel flow, you may still elect to fly in Analog class. Many participants choose to go this route in the name of proficiency and perceived scoring advantages. Simply disable or cover the offending digital instrumentation - this may be declared and checked at registration and aircraft impound. Rally crews can also mix and match classes - fly Digital Navigation and Analog Fuel - if desired. This allows for use of GPS-coupled EFBs and ADS-B without impacting fuel scoring. If your aircraft was certified with GPS or digital fuel flow (i.e. a G1000 panel), Digital class will be your only option. Not to worry - our 2015 rally winner flew a Cirrus in this configuration!
