* F.F.: Fuel Flow in GPH
* TAS: True Airspeed is IAS corrected for instrument error, temperature, and pressure.
* Ignition: Retard spark above 2500 RPM with low blowers, and above 2400 RPM with high blowers. Except when the checklist directs otherwise, use Normal Spark below these RPM settings.
* Above table is calculated from Operations Manual graphs (pages A6-38, figure A6-36 (sheet 1 of 5) to A6-42, figure A6-36 (sheet 5 of 5). Use these tables for other flight conditions.
