CHECK Original N-6 Normal Procedures SR20 Normal Checklist DEFINITIONS OF TYPES OF STARTS Warm Start – If the aircraft has flown within the last hour or two and the engine oil on the dipstick is warm or hot to the touch then the engine is warm. First Start of the Day – If the engine is cool to the touch and the oil on the dipstick is cool to the touch then the engine will need to be primed for the start. This would be typical of an aircraft that has just been pulled out of the hangar for the first flight of the day. Cold “Cold Soaked” Start (winter operations) – If the aircraft has been sitting in temperatures of ≤ 20° F (-7° C) for a period of more than two hours then the engine is “Cold Soaked” and will need to be primed at least 10 seconds and then boost for the start. Be sure the oil pressure comes up within 60 seconds after start. If it doesn’t, shut down the engine and inform maintenance. If the engine fires but fails to start and the firing diminishes in strength, the spark plugs have most likely become frosted and the aircraft must then be preheated to alleviate this problem. Flooded Start – If you have primed the engine and the presence of fuel under the aircraft is visible then you most likely have a flooded engine. Over priming is also evident by weak firing and puffs of black smoke from the exhaust stack. A flooded engine could possibly cause an engine fire on start. You should review the “Engine Fire During Start” checklist before continuing with a flooded start. Flooded Start Procedure 1. Fuel Pump...................................................................................... Off 2. Allow fuel to drain from intake tubes .........................(10-20 seconds) 3. Mixture .............................................................................. Idle Cutoff 4. Throttle ......................................................................................... Full 5. Crank Engine to Clear Fuel If engine fires, retard throttle and slowly advance the mixture to full rich. As the engine begins to run advance the throttle slightly to keep the engine running. If engine does not start, perform “First Start of the Day” procedure. Original N-7 Normal Procedures SR20 Normal Checklist 1. 2. 3. 4.

Maintain Positive Aircraft control at all times. 2. Check heading indicator with the magnetic compass. Reset heading indicator as necessary (if applicable to aircraft). 3. Maintain original heading, or circle present position over a prominent landmark. 4. If at low altitude, climb to a higher altitude. 5. Using GPS: Navigate to nearest airport 6. Using the sectional chart, attempt to locate and identify any prominent landmark. 7. Using available Navaids (VOR triangulation, GPS) to determine position. 8. If unable to determine position, commit to the six C’s: 1. 2. 3. 4. 5. 6. 9. CONFESS – Admit to yourself you are lost. CLIMB – Climb to avoid obstructions, gain better visibility and radio reception. CIRCLE – Pick a nearby landmark and stay in the general vicinity of the landmark. COMMUNICATE – Talk to ATC/FSS. COMPLY – Follow ATC/FSS instructions. CONSERVE – Monitor fuel available. If unable to determine a facility frequency, or unable to establish radio contact, transmit the situation on frequency 121.50 MHz (emergency). Original W - 10 WMU Procedures WMU Practice Areas and Safety of Flight IN-FLIGHT INTERCEPT PROCEDURES If you are intercepted by a U.S. Military or law enforcement aircraft, immediately: 1. Follow the instructions given by the intercepting aircraft. (See chart below) 2. Notify ATC, if possible 3. Attempt to communicate with ATC on the emergency frequency 121.5 MHz, giving the identity and position of your aircraft and the nature of the flight. 4. If equipped with a transponder, squawk 7700, unless otherwise instructed by ATC. If any instructions received by radio from any sources conflict with those given by the intercepting aircraft by visual or radio signals, request clarification while continuing to comply with the instructions given by the intercepting aircraft. I understand and will comply. Meaning Rocks wings and follows.(Also, at night, flashes navigational lights.) I understand and will comply. Intercepted aircraft response You have been intercepted. Rocks Wings. Meaning Rock wings. After acknowledgement initiates a slow level turn, normally to the left, into the desired heading. (Also, at night flashes the navigational lights>) You may proceed Intercepting aircraft signals Performs an abrupt breakaway maneuver consisting of a climbing 90 degree turn, or more, without crossing the intercepted aircraft’s flight path. WMU Procedures W - 11 Original Original W - 12 In Distress Cannot Comply DAY or NIGHT-Regular switching on and off of all available lights but in such a manner as to be distinct from flashing lights. DAY or NIGHT-Irregular flashing of all available lights. Aerodrome you have designated is inadequate Meaning Intercepted aircraft signals Raises landing gear while flying over runway between 1,000’ and 2,000’ and continues to circle the airport. (Also, at night, will also flash landing light.) Lowers landing gear, follows the intercepting aircraft and lands if the runway is considered safe. (Also at night shows steady landing lights on.)

WMU Practice Areas and Safety of Flight WMU Procedures WMU Practice Areas and Safety of Flight Loss Of Communication Immediate Action Items • Fly the airplane / Remain Calm • Check the volume controls and audio panel settings • Check for stuck microphone • Check microphone/headset jacks and plugs • Check circuit breakers and electrical system status VFR Conditions: if the failure occurs in VFR conditions, or if VFR conditions are encountered after the failure, each pilot shall remain under VFR and land as soon as practical. IFR Conditions: if the failure occurs in IFR conditions, A) Route. (1) Route ASSIGNED in the last ATC clearance received (2) If being VECTORED, by the direct route from the point of radio failure to the fix, route, or airway specified in the vector clearance. (3) In the absence of an assigned route, by the route that ATC has advised may be EXPECTED in a further clearance. (4) In the absence of the above, by the route FILED in the flight plan. B) Altitude. At the highest of the following altitudes or flight levels for the route segment being flown (1) The MINIMUM ALTITUDE for IFR operations (2) The altitude ATC has advised may be EXPECTED in a further clearance. (3) The altitude or flight level ASSIGNED in the last ATC clearance received C) Leave clearance limit. (4) When the clearance limit is a fix from which an approach begins, commence descent or descent and approach as close as possible to the EFC time if one has been received, or if one has not been received, as close as possible to the ETA as calculated from the filed or amended (with ATC) estimated time en route. (5) If the clearance limit is not a fix from which an approach begins, leave the clearance limit at the EFC time if one has been received, or if none has been received, upon arrival over the clearance limit, and proceed to a fix from which an approach begins and commence descent or descent and approach as close as possible to the ETA as calculated from the filed or amended (with ATC) estimated time en route.

Clasp both hands around the handle and pull straight down in a strong, steady and continuous motion. Maintain maximum pull force until the rocket activates. Pull forces up to, or exceeding, 45 pounds may be required. Bending of the handle-housing mount is to be expected. Warning: Jerking or rapidly pulling on the activation T-handle will greatly increase the pull forces required to activate rocket.
