Seminole Operations Flashcards
Approach Speed of 100 KIAS within 10 NM of Airport.
Ensure that all ACP’s slow the aircraft to 100 KIAS within 10 NM of the airport. This procedure is required for training and crew cross-country flights. If ATC requests that you keep your speed up, the max speed will be 120 KIAS. The 100 KIAS assists on setting up for
the approach and allows for more time to scan the area for traffic avoidance.
Cruise Power Settings on Cross Country Flights
During preflight planning students will reference the Fuel and Power Chart and Speed Power Chart in Section 5 of the Piper Seminole Information Manual to determine 55% rated power.
Engine Starting Tips - Cold Weather and Weak Battery
Minimize the time the master switch is on when accomplishing the Interior Pre-Flight Check list
so as not to drain the battery unnecessarily. If the temperature is below 10 degrees F have the
engines preheated if it is the first start of the day.
Prime the engine with (4 strokes on 1979) or (4 seconds w/primer button on 2000) to spray fuel into the #1, 2 and 4 cylinders. Open the throttle about 1/4 inch. Do not cycle the throttle during start. Cycling the throttle may add too much fuel to the carburetor, which could cause an engine fire. You may continue to prime the engine after it begins to start until engine is running
smoothly. If the engine begins to start and then stops, turn the Master Off, Re-Prime the engine, Master
back to top > Revised: 11/29/2018
On and attempt another start. Normally engage the starter for no more than 5 seconds then release. Evaluate if more prime is
needed and attempt another 5-second start up to 10-second max. If no luck, try the other
engine. On both the 1979 and 2000 Seminoles when engaging the starter and the propeller turns less
than a full revolution and stops — RELEASE THE STARTER. A weak battery may not be strong
enough for the starter to rotate the prop through the compression stroke. A tried and true technique is to completely release starter, verify no prop movement and immediately engage the starter until the prop rotates through the compression stroke and
continues to rotate for start. This technique is called “Bumping the Starter”. Seminole Instructor Manual Bulletin 01-02 Page 2 of 2 2000 Seminole. If you keep the starter engaged and the prop stops at the compression stroke, the battery will be immediately drained. If no luck starting either engine, perform a Shut Down (Securing) Checklist and review the
POH/AFM for a possible external power start (4.13e) and/or contact MX/Flight Operations.
Following the first engine start, turn the alternator on and idle at no more than 1000 RPM for
approximately 3 minutes or until an indication of oil temp rising. Now idle the engine up to
approx 1200 RPM or 1500 RPM max to charge the battery until the amp meter is below 20
amps. At that point the battery should be sufficiently charged to start the second engine.
Cowl Flap Operation
● ON BEFORE TAKEOFF CHECKLIST, IF OUTSIDE AIR TEMPERATURE IS LESS
THAN 40F, CLOSE COWL FLAPS.
● ON BEFORE TAKEOFF CHECKLIST, IF OUTSIDE AIR TEMPERATURE IS 40F OR
HIGHER, OPEN COWL FLAPS.
● DO NOT OPEN COWL FLAPS AT AIRSPEEDS GREATER THAN 100 KIAS
Gear Horn is an Action Horn
● WHEN THE INSTRUCTOR HEARS THE GEAR HORN AN ACTION MUST BE TAKEN.
● WHEN SIMULATING AN ENGINE FAILURE WITH THE THROTTLE, THE GEAR HORN
SHOULD NEVER BE SOUNDED FOR MORE THAN 20 SECONDS.
● THE GEAR HORN SHOULD NEVER BE HEARD BELOW 1000’ AGL ON ARRIVALS.
● SILENCING THE GEAR HORN IS NEVER ACCEPTABLE IN THE AIRPLANE OR IN
THE SIM. TRAIN IN THE SIM AS YOU TRAIN IN THE AIRPLANE.
The gear horn is to be considered an action horn in the multi-engine training environment with
ATP. When the horn is sounded, extend the gear or apply power to maintain altitude and/or
climb. There are only four conditions when the gear horn should intentionally sound in the
training environment:
1. Performing the VMC Demo with the left throttle retarded, which is only accomplished at
or above 4000’ AGL.
2. Performing a gear-up, clean, power-off stall.
3. Performing a simulated engine failure with the throttle after takeoff or on a go- around
above 500’ AGL.
4. Performing a simulated engine failure prior to the final approach fix or segment
The gear horn should never sound below 1000’AGL unless the Instructor is utilizing engine failure scenario 3 for training in the takeoff or go-around maneuver. If the gear horn is heard below 1000’AGL except when operating in scenario 3, GO-AROUND
Emergency Descents – 120 KIAS
ATP conducts emergency descent training at 120 KIAS due to the frequency of simulated emergency descents for training purposes.
Engine-Out Training Scenarios in Four Phases of
Flight
Inducing Simulated Engine Failures
Simulate engine failures with the throttle or mixture only. ATP operations prohibit failing engines
with fuel selectors, magnetos, or any other method.
● Below 3000’ AGL - Throttle (except during the takeoff roll where mixture is permitted)
● Above 3000’ AGL - Mixture
● 4000’ AGL - Shutdown Altitude (Intentional engine shutdowns (feathering) for training purposes
restricted to 4000’ AGL and above)
If at any point the student does not correctly recover from these scenarios, the instructor
must immediately:
1. Take control of the aircraft
2. Stop training
3. Restore power on the affected engine
