Peggy Pal

Peggy Pal puts the numbers a tanker crew actually needs in one place — holdover times, wind additives, frag math, fuel planning and the mission timeline.

Made for KC-46 and KC-135 crews.

WINTER OPS • Holdover times from the 2026–27 FAA Holdover Time Guidelines. Set fluid type and concentration, precipitation, visibility, day or night, and OAT, and get the FAA range for those exact conditions. • METAR auto-fill: enter an ICAO and the app reads temperature, visibility and present weather off the current report, then selects the right FAA table. • Live countdown timer with a Lock Screen Live Activity, so the clock keeps running while you finish the checklist. Start it now, or back-date it to when the final application began. • The full FAA holdover tables are bundled in the app, so they are there with no signal. • Cold weather altitude corrections for IAF, FAF, MDA/DA and missed approach altitudes.

KC-46 WIND ADDITIVE • Set the wind on a graphic runway compass or type it in. Headwind component, crosswind component and vREF additive update live as you move the dial.

FUEL AND FRAG • Frag calculator: current fuel, offload remaining, bingo and planned exit time give you time remaining on station, max time on station with and without the frag, and fuel plus-minus. • Fuel load estimator: flight time, offload and desired landing fuel produce a ramp load with a tank-by-tank breakdown you can share. • KC-46 and KC-135 fuel flows built in, or enter your own.

MISSION TIMELINE • A full sequence of events from one takeoff time — show, brief, bus, takeoff and end of FDP, in Zulu and local. • Basic or augmented crew, local or TDY timelines, and editable offsets so the times match how your unit actually runs. • Optional duties prompt and standing aircrew notes, then share the SOE with the crew in a tap.

CREW REST • Post mission crew rest from departure and mission completion times, across time zones, ready to share.
