• Mitigations: o File IFR
o Remain on the ground until receiving an IFR release, instead of departing VFR to pick up a clearance in the busy airspace
❱ Possible delay contacting Albuquerque Departure because of terrain at my climb rate
• Mitigations:
o Follow procedures precisely to be predictable to ATC and other pilots
o Aviate, navigate, then communicate. Don’t worry
if it takes time to talk to Departure. I’ll be on aN IFR clearance even if I can’t talk right away
Expectations
❱ Full throttle will be about 23 inches manifold pressure at this pressure altitude and 2700 rpm
❱ Fuel flow and EGT will be higher than optimum; lean to about 1300°F and crosscheck this is about 21 gallons per hour per side at the beginning of the takeoff roll
❱ Takeoff roll is computed at 1,740 feet, obstacle clearance 2,690 feet
• I should lift off a little less than one-third of the way down the runway
• I should be at 50 feet above the ground about halfway down the runway
❱ Takeoff speed 84 KIAS and initial climb speed is 91 KIAS • I should be at about 60 KIAS at about 900 feet
(approximately five runway stripes) down the runway
• I will reach my liftoff speed about 11 stripes down the runway
o Reduce the usual 12° up VXME attitude to 10° to compensate for reduced power
o Delay gear retraction beyond initial “positive rate” until confirming that the positive rate of climb
is sustained (sometimes airplanes “settle” at high- density altitudes)
❱ Accelerate/stop distance is approximately 3,700 feet, leaving about 2,500 feet of runway remaining if I start my takeoff roll from the departure numbers
❱ Cruise climb will initially be about 700 feet per minute with leaning to target EGT each 1,000 feet in the climb
Normal Departure
❱ The Obstacle Departure Procedure for Runway 28 calls for a climbing left turn to the SAF VOR, then a climb in the published hold to MEA before departing en route
❱ From there a left turn to the southeast takes me toward my first fix, around the southern edge of the obscured mountains
❱ My filed altitude is 10,000 feet, which is the minimum obstacle clearance altitude along my direction of flight
❱ Altitude and precise departure route may be modified by ATC March 2019
