Is there a recommended inflation rate for forecasting future aircraft and engine values?

Our inflation rate views are at the macro level. i.e. we wouldn’t apply different rates to different aircraft. We produce all our future forecasts at a 0% constant rate of inflation and we currently take 2% as our baseline inflation rate assumption to apply to all assets but that sits alongside our 0%. We do limit the range of inflation rates that users can pick for our appraisals to between 0 and 3%, as outside 3% the assumptions we use to create our 0% future values wouldn’t be representative. We have different 0% future value projections for each aircraft type/value subseries, which is arguably how we might see the difference in the impact of inflation affecting different aircraft types in real terms.
